v0.9.0

⚠️ Breaking changes

• Minimum deployment targets raised: iOS 15.0 (was 13.0), macOS 12.0 (was 11.5), tvOS 15.0 (was 13.0), watchOS 9.0 (was 6.0). visionOS 1.0 is unchanged.
  Projects that need older OS versions must stay on 0.8.2.
• There are no public API changes.

Improvements

• Xcode 27.1 / Swift 6.4 compatibility; the Xcode project now builds in Swift 6 language mode (SWIFT_VERSION = 6.0), matching Package.swift.
• Replaced the deprecated NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(_:) in DelegatedStorage.object(forKey:) with the non-deprecated unarchiver API, keeping the same behavior (archived NSCoding objects keep decoding). The library now builds without deprecation warnings.
• Added GitHub Actions CI (.github/workflows/ci.yml) on the xcode-27 runner image using Xcode 27.1: SwiftPM resolve + clean build + tests on macOS, tests on iPhone 17 Simulator (iOS 27.0), build checks for macOS, Mac Catalyst, iOS, tvOS, watchOS and visionOS, and an external-consumer integration check. Added Dependabot for the workflow actions.

Tests

• swift test compiles and runs again with Swift 6 (it failed to compile before): test classes are isolated to @StorageActor, expectations use fulfillment(of:), and the non-isolated allTests lists were removed.
• Removed the dead Linux scaffolding (Tests/LinuxMain.swift, XCTestManifests.swift), which referenced a non-existent module and is not used by SwiftPM on current toolchains.
• Added StorageTests (18 tests): primitive/codable/NSCoding round trips, missing keys, removal, register(defaults:), key hashing and value encryption, wrong key / authentication tag errors, corrupted data, DataConvertible edge cases and SymmetricKey round trip. Total: 56 tests.

Documentation

• Clarify that SingletonStorageDelegate uses in-memory storage. #42 Thanks @dajiaohuang!

Tooling

• Disabled the wrapPropertyBodies, wrapFunctionBodies, blankLinesBetweenScopes and wrapArguments SwiftFormat rules, which newer SwiftFormat versions flag on the existing code style.
