0.3.0

0.3.0 makes many changes from 0.2.0. Where possible, old names and types are available with deprecation attributes; these will soon be removed.

• Updated threading model:
  • MobiusLoop is now single-threaded
  • MobiusController runs a loop on a single background queue.
  • Fixed several issues around hard-to-avoid assertions in loop teardown.
• New EffectRouter and EffectHandler replace EffectRouterBuilder (which is deprecated along with several helpers).
• Effects in First and Next are now an array rather than a set. This doesn’t imply an ordering guarantee, but does mean that effects don’t have to be Hashable.
• Various things renamed or changed from methods to properties to better conform to Swift API Guidelines and for internal consistency:
  • Initiator is now Initiate, and is only used with MobiusController.
  • MobiusLoop.getMostRecentModel() becomes latestModel.
  • MobiusController.getModel() becomes model.
  • Connectable.InputType and OutputType become Input and Output; Connection.ValueType becomes Value.
• Update is now a struct. This isn’t leveraged by Mobius itself at the moment, but makes it easier to write transformations on updates in a fluent style.
• For consistency, MobiusController is created through a makeController() method on Mobius.Builder instead of being initialized with a builder argument.
• All methods on MobiusLogger now have default do-nothing implementations.
• ConsoleLogger has been replaced with SimpleLogger, which can take a consumer function to use instead of print.
• NoEffect and BrokenConnection are deprecated.
• MobiusHooks.ErrorHandler now returns Never rather than Void.
• Mobius no longer adds a public extension to NSRecursiveLock.
• There are more documentation comments than there used to be.
• Tooling updated to Swift 5.0 and Xcode 11.0.
• Swift Package Manager is explicitly supported for all Apple platforms; Carthage and CocoaPods are supported for iOS only.
