API Breaking Changes

  • None.

Enhancements

  • Add SyncPermissionOffer and SyncPermissionOfferResponse classes to allow creating and accepting permission change events to synchronized Realms between different users.
  • Support monitoring sync transfer progress by registering notification blocks on SyncSession. Specify the transfer direction (.upload/.download) and mode (.reportIndefinitely/.forCurrentlyOutstandingWork) to monitor.

  • Fix a call to commitWrite(withoutNotifying:) committing a transaction that would not have triggered a notification incorrectly skipping the next notification.
  • Fix incorrect results and crashes when conflicting object insertions are merged by the synchronization mechanism when there is a collection notification registered for that object type.

2.2.0 Release notes (2017-01-12)

Sync Breaking Changes (In Beta)

  • Sync-related error reporting behavior has been changed. Errors not related to a particular user or session are only reported if they are classed as 'fatal' by the underlying sync engine.
  • Added RLMSyncErrorClientResetError to RLMSyncError enum.

API Breaking Changes

Deprecated API New API
-[RLMArray sortedResultsUsingProperty:] -[RLMArray sortedResultsUsingKeyPath:]
-[RLMCollection sortedResultsUsingProperty:] -[RLMCollection sortedResultsUsingKeyPath:]
-[RLMResults sortedResultsUsingProperty:] -[RLMResults sortedResultsUsingKeyPath:]
+[RLMSortDescriptor sortDescriptorWithProperty:ascending] +[RLMSortDescriptor sortDescriptorWithKeyPath:ascending:]
RLMSortDescriptor.property RLMSortDescriptor.keyPath
  • The following Swift APIs have been deprecated in favor of newer or preferred versions:

Enhancements

  • Introduce APIs for safely passing objects between threads. Create a thread-safe reference to a thread-confined object by passing it to the +[RLMThreadSafeReference referenceWithThreadConfined:]/ThreadSafeReference(to:) constructor, which you can then safely pass to another thread to resolve in the new Realm with -[RLMRealm resolveThreadSafeReference:]/Realm.resolve(_:).
  • Realm collections can now be sorted by properties over to-one relationships.
  • Optimized CONTAINS queries to use Boyer-Moore algorithm (around 10x speedup on large datasets).

Bugfixes

  • Setting deleteRealmIfMigrationNeeded now also deletes the Realm if a file format migration is required, such as when moving from a file last accessed with Realm 0.x to 1.x, or 1.x to 2.x.
  • Fix queries containing nested SUBQUERY expressions.
  • Fix spurious incorrect thread exceptions when a thread id happens to be reused while an RLMRealm instance from the old thread still exists.

    • migration block set with a sync configuration.
  • Greatly improve performance of write transactions which make a large number of changes to indexed properties, including the automatic migration when opening files written by Realm 1.x.

Bugfixes

  • Reset sync metadata Realm in case of decryption error.
  • Fix issue preventing using synchronized Realms in Xcode Playgrounds.
  • Fix assertion failure when migrating a model property from object type to RLMLinkingObjects type.

  • Logged-out users are no longer returned from +[RLMSyncUser currentUser] or +[RLMSyncUser allUsers].
  • Fix several issues which could occur when the 1001st object of a given type was created or added to an RLMArray/List, including crashes when rerunning existing queries and possibly data corruption.
  • Fix a potential crash when the application exits due to a race condition in the destruction of global static variables.
  • Fix race conditions when waiting for sync uploads or downloads to complete which could result in crashes or the callback being called too early.

Sync Breaking Changes (In Beta)

  • None.

API breaking changes

  • None.

Enhancements

  • Add the ability to skip calling specific notification blocks when committing a write transaction.

  • Fix some scenarios which would lead to inconsistent states when using collection notifications.
  • Fix several race conditions in the notification functionality.
  • Don't send Realm change notifications when canceling a write transaction.

2.0.4 Release notes (2016-11-14)

Sync Breaking Changes (In Beta)

  • Fix a crash that could occur when working with a RLMLinkingObject property of an unmanaged object.

2.0.2 Release notes (2016-10-05)

This release is not protocol-compatible with previous version of the Realm Mobile Platform.

API breaking changes

2.0.1 Release notes (2016-09-29)

Bugfixes

  • Fix an assertion failure when opening a Realm file written by a 1.x version of Realm which has an indexed nullable int or bool property.

2.0.0 Release notes (2016-09-27)

This release introduces support for the Realm Mobile Platform! See https://realm.io/news/introducing-realm-mobile-platform/ for an overview of these great new features.

API breaking changes

  • By popular demand, RealmSwift.Error has been moved from the top-level namespace into a Realm extension and is now Realm.Error, so that it no longer conflicts with Swift.Error.
  • Files written by Realm 2.0 cannot be read by 1.x or earlier versions. Old files can still be opened.

Enhancements

  • The .log, .log_a and .log_b files no longer exist and the state tracked in them has been moved to the main Realm file. This reduces the number of open files needed by Realm, improves performance of both opening and writing to Realms, and eliminates a small window where committing write transactions would prevent other processes from opening the file.

Bugfixes

  • Fix an assertion failure when sorting by zero properties.
  • Fix a mid-commit crash in one process also crashing all other processes with the same Realm open.
  • Properly initialize new nullable float and double properties added to existing objects to null rather than 0.
  • Fix a stack overflow when objects with indexed string properties had very long common prefixes.
  • Fix a race condition which could lead to crashes when using async queries or collection notifications.
  • Fix a bug which could lead to incorrect state when an object which links to itself is deleted from the Realm.

1.1.0 Release notes (2016-09-16)

This release brings official support for Xcode 8, Swift 2.3 and Swift 3.0. Prebuilt frameworks are now built with Xcode 7.3.1 and Xcode 8.0.

API breaking changes

  • Deprecate migrateRealm: in favor of new performMigrationForConfiguration:error: method that follows Cocoa's NSError conventions.
  • Fix issue where RLMResults used idinstead of its generic type as the return type of subscript.

Enhancements

  • Improve error message when using NSNumber incorrectly in Swift models.
  • Further reduce the download size of the prebuilt static libraries.
  • Improve sort performance, especially on non-nullable columns.
  • Allow partial initialization of object by initWithValue:, deferring required property checks until object is added to Realm.

Bugfixes

  • Fix incorrect truncation of the constant value for queries of the form column < value for float and double columns.
  • Fix crash when an aggregate is accessed as an Int8, Int16, Int32, or Int64.
  • Fix a race condition that could lead to a crash if an RLMArray or List was deallocated on a different thread than it was created on.
  • Fix a crash when the last reference to an observed object is released from within the observation.
  • Fix a crash when initWithValue: is used to create a nested object for a class with an uninitialized schema.
  • Enforce uniqueness for RealmOptional primary keys when using the value setter.

1.0.2 Release notes (2016-07-13)

API breaking changes

  • Attempting to add an object with no properties to a Realm now throws rather than silently doing nothing.

Enhancements

  • Swift: A write block may now throw, reverting any changes already made in the transaction.
  • Reduce address space used when committing write transactions.
  • Significantly reduce the download size of prebuilt binaries and slightly reduce the final size contribution of Realm to applications.
  • Improve performance of accessing RLMArray properties and creating objects with List properties.

Bugfixes

  • Fix a crash when reading the shared schema from an observed Swift object.
  • Fix crashes or incorrect results when passing an array of values to createOrUpdate after reordering the class's properties.
  • Ensure that the initial call of a Results notification block is always passed .Initial even if there is a write transaction between when the notification is added and when the first notification is delivered.
  • Fix a crash when deleting all objects in a Realm while fast-enumerating query results from that Realm.
  • Handle EINTR from flock() rather than crashing.
  • Fix incorrect behavior following a call to [RLMRealm compact].
  • Fix live updating and notifications for Results created from a predicate involving an inverse relationship to be triggered when an object at the other end of the relationship is modified.

1.0.1 Release notes (2016-06-12)

API breaking changes

  • None.

Enhancements

  • Significantly improve performance of opening Realm files, and slightly improve performance of committing write transactions.

Bugfixes

  • Swift: Fix an error thrown when trying to create or update Object instances via add(:_update:) with a primary key property of type RealmOptional.
  • Xcode playground in Swift release zip now runs successfully.
  • The key parameter of Realm.objectForPrimaryKey(_:key:)/ Realm.dynamicObjectForPrimaryKey(_:key:) is now marked as optional.
  • Fix a potential memory leak when closing Realms after a Realm file has been opened on multiple threads which are running in active run loops.
  • Fix notifications breaking on tvOS after a very large number of write transactions have been committed.
  • Fix a "Destruction of mutex in use" assertion failure after an error while opening a file.
  • Realm now throws an exception if an Object subclass is defined with a managed Swift lazy property. Objects with ignored lazy properties should now work correctly.
  • Update the LLDB script to work with recent changes to the implementation of RLMResults.
  • Fix an assertion failure when a Realm file is deleted while it is still open, and then a new Realm is opened at the same path. Note that this is still not a supported scenario, and may break in other ways.

1.0.0 Release notes (2016-05-25)

No changes since 0.103.2.

0.103.2 Release notes (2016-05-24)

API breaking changes

  • None.

API breaking changes

  • None.

Enhancements

  • None.

Bugfixes

  • Fix a bug that sometimes resulted in a single object's NSData properties changing from nil to a zero-length non-nil NSData when a different object of the same type was deleted.

0.103.0 Release notes (2016-05-18)

API breaking changes

  • All functionality deprecated in previous releases has been removed entirely.
  • Support for Xcode 6.x & Swift prior to 2.2 has been completely removed.
  • RLMResults/Results now become empty when a RLMArray/List or object they depend on is deleted, rather than throwing an exception when accessed.
  • Migrations are no longer run when deleteRealmIfMigrationNeeded is set, recreating the file instead.

Enhancements

  • Added invalidated properties to RLMResults/Results, RLMLinkingObjects/LinkingObjects, RealmCollectionType and AnyRealmCollection. These properties report whether the Realm the object is associated with has been invalidated.
  • Some NSErrors created by Realm now have more descriptive user info payloads.

Bugfixes

  • None.

0.102.1 Release notes (2016-05-13)

Bugfixes

  • RLMLinkingObjects properties declared in Swift subclasses of RLMObject now work correctly.
  • Fix an assertion failure when deleting all objects of a type, inserting more objects, and then deleting some of the newly inserted objects within a single write transaction when there is an active notification block for a different object type which links to the objects being deleted.
  • Fix crashes and/or incorrect results when querying over multiple levels of LinkingObjects properties.
  • Fix opening read-only Realms on multiple threads at once.
  • Fix a BadTransactLog exception when storing dates before the unix epoch (1970-01-01).

API breaking changes

  • None.

Enhancements

  • Add a method to rename properties during migrations:
    • Swift: Migration.renamePropertyForClass(_:oldName:newName:)
    • Objective-C: -[RLMMigration renamePropertyForClass:oldName:newName:]
  • Add deleteRealmIfMigrationNeeded to RLMRealmConfiguration/Realm.Configuration. When this is set to true, the Realm file will be automatically deleted and recreated when there is a schema mismatch rather than migrated to the new schema.

Bugfixes

  • Fix BETWEEN queries that traverse RLMArray/List properties to ensure that a single related object satisfies the BETWEEN criteria, rather than allowing different objects in the array to satisfy the lower and upper bounds.
  • Fix a race condition when a Realm is opened on one thread while it is in the middle of being closed on another thread which could result in crashes.
  • Fix a bug which could result in changes made on one thread being applied incorrectly on other threads when those threads are refreshed.
  • Fix crash when migrating to the new date format introduced in 0.101.0.
  • Fix crash when querying inverse relationships when objects are deleted.

0.101.0 Release notes (2016-05-04)

  • Crashing while in the middle of a write transaction no longer blocks other processes from performing write transactions on the same file.
  • Improve the performance of refreshing a Realm (including via autorefresh) when there are live Results/RLMResults objects for that Realm.

Bugfixes

  • Fix an assertion failure of "!more_before || index >= std::prev(it)->second)" in IndexSet::do_add().
  • Fix a crash when an RLMArray or List object is destroyed from the wrong thread.

0.100.0 Release notes (2016-04-29)

API breaking changes

  • -[RLMObject linkingObjectsOfClass:forProperty] and Object.linkingObjects(_:forProperty:) are deprecated in favor of properties of type RLMLinkingObjects / LinkingObjects.

Enhancements

  • The automatically-maintained inverse direction of relationships can now be exposed as properties of type RLMLinkingObjects / LinkingObjects. These properties automatically update to reflect the objects that link to the target object, can be used in queries, and can be filtered like other Realm collection types.
  • Queries that compare objects for equality now support multi-level key paths.

Bugfixes

  • Fix an assertion failure when a second write transaction is committed after a write transaction deleted the object containing an RLMArray/List which had an active notification block.
  • Queries that compare RLMArray / List properties using != now give the correct results.

  • The block for -[RLMArray addNotificationBlock:] and -[RLMResults addNotificationBlock:] now takes another parameter.
  • The following Objective-C APIs have been deprecated in favor of newer or preferred versions:
Deprecated API New API

RLMRealmConfiguration.path RLMRealmConfiguration.fileURL
RLMRealm.path RLMRealmConfiguration.fileURL
RLMRealm.readOnly RLMRealmConfiguration.readOnly
+[RLMRealm realmWithPath:] +[RLMRealm realmWithURL:]

+[RLMRealm schemaVersionAtPath:error:] +[RLMRealm schemaVersionAtURL:encryptionKey:error:]
+[RLMRealm schemaVersionAtPath:encryptionKey:error:] +[RLMRealm schemaVersionAtURL:encryptionKey:error:]
  • The following Swift APIs have been deprecated in favor of newer or preferred versions:
Deprecated API New API
Realm.removeNotification(_:) NotificationToken.stop()
Realm.Configuration.path Realm.Configuration.fileURL
Realm.path Realm.Configuration.fileURL
Realm.readOnly Realm.Configuration.readOnly
Realm.writeCopyToPath(_:encryptionKey:) Realm.writeCopyToURL(_:encryptionKey:)

API breaking changes

  • None.

Enhancements

  • None.

Bugfixes

  • Mark further initializers in Objective-C as NS_DESIGNATED_INITIALIZER to prevent that these aren't correctly defined in Swift Object subclasses, which don't qualify for auto-inheriting the required initializers.
  • -[RLMResults indexOfObjectWithPredicate:] now returns correct results for RLMResults instances that were created by filtering an RLMArray.
  • Adjust how RLMObjects are destroyed in order to support using an associated object on an RLMObject to remove KVO observers from that RLMObject.
  • -[RLMResults indexOfObjectWithPredicate:] now returns the index of the first matching object for a sorted RLMResults, matching its documented behavior.
  • Fix a crash when canceling a transaction that set a relationship.

0.98.3 Release notes (2016-02-26)

Enhancements

  • Initializing the shared schema is 3x faster.

Bugfixes

  • Using Realm Objective-C from Swift while having Realm Swift linked no longer causes that the declared ignoredProperties are not taken into account.

Enhancements

  • Aggregate operations (ANY, NONE, @count, SUBQUERY, etc.) are now supported for key paths that begin with an object relationship so long as there is a RLMArray/List property at some point in a key path.

  • Fix a deadlock when queries are performed within a Realm notification block.
  • The ANY / SOME / NONE qualifiers are now required in comparisons involving a key path that traverse a RLMArray/List property. Previously they were only required if the first key in the key path was an RLMArray/List property.
  • Fix several scenarios where the default schema would be initialized incorrectly if the first Realm opened used a restricted class subset (via objectClasses/objectTypes).

0.98.1 Release notes (2016-02-10)

  • Fix a crash when deleting an object containing an RLMArray/List with active notification blocks.
  • Fix duplicate file warnings when building via CocoaPods.
  • Fix crash or incorrect results when calling indexOfObject: on an RLMResults derived from an RLMArray.

0.98.0 Release notes (2016-02-04)

  • NSPredicate's SUBQUERY operator is now supported. It has the following limitations:
    • @count is the only operator that may be applied to the SUBQUERY expression.
    • The SUBQUERY(…).@count expression must be compared with a constant.
    • Correlated subqueries are not yet supported.

Bugfixes

  • None.

API breaking changes

  • None.

Enhancements

  • Swift: Added Error enum allowing to catch errors e.g. thrown on initializing RLMRealm/Realm instances.

  • Many forms of queries with key paths on both sides of the comparison operator are now supported.
  • Add support for KVC collection operators in RLMResults and RLMArray.
  • Fail instead of deadlocking in +[RLMRealm sharedSchema], if a Swift property is initialized to a computed value, which attempts to open a Realm on its own.

  • Improved performance of most simple queries.

Bugfixes

  • The interprocess notification mechanism no longer uses dispatch worker threads, preventing it from starving other GCD clients of the opportunity to execute blocks when dozens of Realms are open at once.

API breaking changes

  • Swift: Results.average(_:) now returns an optional, which is nil if and only if the results set is empty.

Enhancements

API breaking changes

  • Xcode 6 is now supported from the main Xcode project Realm.xcodeproj. Xcode 5 is no longer supported.

Enhancements

  • Support subclassing RLMObject models. Although you can now persist subclasses, polymorphic behavior is not supported (i.e. setting a property to an instance of its subclass).
  • Add support for sorting RLMArray properties.
  • Speed up inserting objects with addObject: by ~20%.
  • readonly properties are automatically ignored rather than having to be added to ignoredProperties.
  • Updating to core library version 0.83.1.
  • Return "[deleted object]" rather than throwing an exception when -description is called on a deleted RLMObject.
  • Significantly improve performance of very large queries.

Enhancements

  • Updating to core library version 0.83.0.

  • Added methods to update or insert (upsert) for objects with primary keys defined.
  • [RLMObject initWithObject:] and [RLMObject createInRealmWithObject:] now support any object type with kvc properties.
  • The Swift support has been reworked to work around Swift not being supported in Frameworks on iOS 7.
  • Improve performance when getting the count of items matching a query but not reading any of the objects in the results.
  • Add a return value to -[RLMRealm refresh] that indicates whether or not there was anything to refresh.
  • Add the class name to the error message when an RLMObject is missing a value for a property without a default.
  • Add support for opening Realms in read-only mode.
  • Add an automatic check for updates when using Realm in a simulator (the checker code is not compiled into device builds). This can be disabled by setting the REALM_DISABLE_UPDATE_CHECKER environment variable to any value.
  • Add support for Int16 and Int64 properties in Swift classes.

Bugfixes

  • Realm change notifications when beginning a write transaction are now sent after updating rather than before, to match refresh.
  • -isEqual: now uses the default NSObject implementation unless a primary key is specified for an RLMObject. When a primary key is specified, -isEqual: calls -isEqualToObject: and a corresponding implementation for -hash is also implemented.

0.84.0 Release notes (2014-08-28)

API breaking changes

  • The timer used to trigger notifications has been removed. Notifications are now only triggered by commits made in other threads, and can not currently be triggered by changes made by other processes. Interprocess notifications will be re-added in a future commit with an improved design.

  • Allow unregistering from change notifications in the change notification handler block.
  • Significant performance improvements when holding onto large numbers of RLMObjects.
  • Realm-Xcode6.xcodeproj now only builds using Xcode6-Beta6.

Bugfixes

  • Fix crashes and assorted bugs when sorting or querying a RLMArray returned from a query.
  • Notifications are no longer sent when initializing new RLMRealm instances on background threads.
  • Handle object cycles in -[RLMObject description] and -[RLMArray description].
  • Lowered the deployment target for the Xcode 6 projects and Swift examples to iOS 7.0, as they didn't actually require 8.0.
  • Support setting model properties starting with the letter 'z'
  • Fixed crashes that could result from switching between Debug and Relase builds of Realm.

  • Proper implementation for [RLMArray indexOfObjectWhere:]
  • The default Realm path on OS X is now ~/Library/Application Support/[bundle identifier]/default.realm rather than ~/Documents
  • We now check that the correct framework (ios or osx) is used at compile time.

Bugfixes

  • Fixed rapid growth of the realm file size.
  • Fixed a bug which could cause a crash during RLMArray destruction after a query.
  • Fixed bug related to querying on float properties: floatProperty = 1.7 now works.

0.81.0 Release notes (2014-07-22)

API breaking changes

  • None.

Enhancements

  • Updating to core library version 0.80.3.
  • Added support for basic querying of RLMObject and RLMArray properties (one-to-one and one-to-many relationships). e.g. [Person objectsWhere:@"dog.name == 'Alfonso'"] or [Person objectsWhere:@"ANY dogs.name == 'Alfonso'"] Supports all normal operators for numeric and date types. Does not support NSData properties or BEGINSWITH, ENDSWITH, CONTAINS and other options for string properties.
  • Added support for querying for object equality in RLMObject and RLMArray properties (one-to-one and one-to-many relationships). e.g. [Person objectsWhere:@"dog == %@", myDog] [Person objectsWhere:@"ANY dogs == %@", myDog] [Person objectsWhere:@"ANY friends.dog == %@", dog] Only supports comparing objects for equality (i.e. ==)
  • Added a helper method to RLMRealm to perform a block inside a transaction.
  • OSX framework now supported in CocoaPods.

Bugfixes

  • Fixed Unicode support in property names and string contents (Chinese, Russian, etc.). Closing #612 and #604.
  • Fixed bugs related to migration when properties are removed.
  • Fixed keyed subscripting for standalone RLMObjects.
  • Fixed bug related to double clicking on a .realm file to launch the Realm Browser (thanks to Dean Moore).

0.80.0 Release notes (2014-07-15)

API breaking changes

  • Rename migration methods to -migrateDefaultRealmWithBlock: and -migrateRealmAtPath:withBlock:
  • Moved Realm specific query methods from RLMRealm to class methods on RLMObject (-allObjects: to +allObjectsInRealm: ect.)

Enhancements

  • Added +createInDefaultRealmWithObject: method to RLMObject.
  • Added support for array and object literals when calling -createWithObject: and -initWithObject: variants.
  • Added method -deleteObjects: to batch delete objects from a Realm
  • Support for defining RLMObject models entirely in Swift (experimental, see known issues).
  • RLMArrays in Swift support Sequence-style enumeration (for obj in array).
  • Implemented -indexOfObject: for RLMArray

Known Issues for Swift-defined models

  • Properties other than String, NSData and NSDate require a default value in the model. This can be an empty (but typed) array for array properties.
  • The previous caveat also implies that not all models defined in Objective-C can be used for object properties. Only Objective-C models with only implicit (i.e. primitives) or explicit default values can be used. However, any Objective-C model object can be used in a Swift array property.
  • Array property accessors don't work until its parent object has been added to a realm.
  • Realm-Bridging-Header.h is temporarily exposed as a public header. This is temporary and will be private again once rdar://17633863 is fixed.
  • Does not leverage Swift generics and still uses RLM-prefix everywhere. This is coming in #549.
