* Run the tests on iOS 27.0
Bump the required simulator OS in the preview, UI and Compound tests, and the CI tool's default OS, from 26.5 to 27.0. Test devices stay the same.
iOS 27 writes transcoded videos 146 bytes larger, so update the expected sizes in MediaUploadingPreprocessorTests.
* Build and test on CI with Xcode 27
Select Xcode 27 in ci_common.sh and move every macOS workflow to the xcode-27 runner image, as macos-26 doesn't include Xcode 27. The Compound workflow now also creates its simulator on the iOS 27.0 runtime.
The xcode-27 runners are slower, so give the unit, Enterprise, Compound and snapshot recording jobs longer timeouts.
* Fix the preview snapshot layout on iOS 27
On iOS 27 the hosting controller applies the window's safe area when rendering, but the snapshot size comes from sizeThatFits, which ignores it. Component previews were shifted down and clipped at the bottom. Disable the hosting controller's safe area regions for these snapshots so the measured and rendered layouts match.
swift-snapshot-testing also renders into a window without a scene, and on iOS 27 a navigation stack in such a window reserves space for a large title it never shows, leaving a gap below the navigation bar. Attach the render window to the app's scene until swift-snapshot-testing handles it.
The invite users and add rooms screens sized their selected items row from a measured width stored in state, which is zero on the first layout pass, so snapshots could draw the row empty. Use containerRelativeFrame instead. The add rooms search previews now also wait for their results, and the search previews that show a clear button get a small precision tolerance, as it renders inconsistently in snapshots.
* Re-record the preview snapshots on iOS 27.0
Recorded on an iPhone SE (3rd generation) simulator running iOS 27.0 with Xcode 27.0 (27A266a). The changes come from iOS 27 rendering: text anti-aliasing, hyphenation and line breaking, navigation bars and toggles that now render in snapshots, lazy stacks that were blank on iOS 26, and pseudo-language locale formatting.
* Fix the UI tests on iOS 27
iOS 27 no longer exposes accessibility identifiers on SwiftUI menu items, so the space exploration test now finds them by label within the menu. On iPad, the start chat search field keeps focus after submitting and can swallow the next tap, so retry the tap if the create room screen doesn't appear.
* Re-record the UI test snapshots on iOS 27.0
Recorded on iPhone 17 and iPad (A16) simulators running iOS 27.0 with Xcode 27.0. The changes come from iOS 27 styling, like the keyboard height and glass borders. This also removes the iPad app lock setup snapshots, which have been orphaned since those tests stopped running on iPad.
* Fix the accessibility tests crashing on iOS 27
The accessibility tests' previews wrapper kept its ImageRenderer alive across the awaits that follow the render. On iOS 27, releasing it at that point tears down its view graph outside of a SwiftUI update, which hits an assertion and crashes the app. Release the renderer as soon as the image has been rendered.
* Keep the accessibility tests' image renderers alive on iOS 27
Releasing the ImageRenderer straight away wasn't enough: on iOS 27, releasing one that rendered a preview crashes SwiftUI whichever context it happens in. Keep the renderers alive instead. Each test launches a fresh app, so they only live for the one test.
* Share the UI tests' app settings with their mock user session
Since the user session flow reads its settings from UserSettings, the UI tests' mock user session was wrapping a fresh volatile AppSettings instead of the one the tests configure. The flags that skip onboarding weren't picked up, so every user session UI test got stuck on the notifications permission screen.
* Re-record the Compound snapshots on iOS 27.0
Apply the same safe area fix as the app's preview tests, so size-that-fits snapshots aren't clipped on iOS 27, and re-record the snapshots on an iPhone SE (3rd generation) simulator running iOS 27.0 in English (US).
* Fix a race reading the keyboard in the accessibility tests
On iOS 27 the QR code login screen's keyboard can be dismissing between checking that it exists and reading its frame, which fails the test. Snapshot it in a single query instead.
* use observation in unit and preview tests instead of the async stream
* use a parsing approach that is independent of the sourcery annotation
* Fix observation deferred fulfillments not receiving the initial value
Observation's observe only emits transitions, not the value present at subscription time. Drop the leading initial value from the affected transitionValues sequences and assert it directly with #expect instead.
* improved docs
* Enable Swift 6.2 with default main actor isolation for the app target
Turn on SWIFT_VERSION 6.2, SWIFT_APPROACHABLE_CONCURRENCY and SWIFT_DEFAULT_ACTOR_ISOLATION = MainActor for the ElementX target, matching the NSE and Share Extension (which already use 6.2 without the main actor default).
# Conflicts:
# ElementX.xcodeproj/project.xcworkspace/xcshareddata/swiftpm/Package.resolved
* Update the code generation templates for Swift 6
Emit nonisolated/@unchecked Sendable mocks and nonisolated string enums, and mark async mock methods @concurrent so they keep suspending like the real implementations (otherwise intermediate states are unobservable in tests). Includes the regenerated mocks and strings.
# Conflicts:
# ElementX/Sources/Mocks/Generated/GeneratedMocks.swift
* Make the data layer and services nonisolated and Sendable
Annotate the value-type models, Rust SDK proxy wrappers, timeline item graph, settings, logging and NSE-shared types as nonisolated, and conform the service protocols to Sendable so their existentials can cross isolation boundaries. These types run off the main actor and no longer inherit the target's default main actor isolation.
* Adopt the new isolation across call sites, mocks and signatures
Update call sites, closure signatures and mock configuration helpers to match the nonisolated/Sendable data layer, including the main actor isolated mock inits and the @Sendable filter on recentlyVisitedRooms.
^ Conflicts:
^ ElementX/Sources/Services/SecureBackup/SecureBackupController.swift
* Remove redundant @MainActor annotations
With the app target defaulting to main actor isolation, the explicit @MainActor on view models, coordinators, views and their protocols is no longer required.
* Fix concurrency hotspots surfaced by the migration
Resolve the room summary main-thread deadlock by moving diff processing onto AsyncStreams, add the SDKListener.onMainActor FIFO bridge for SDK callbacks, hop KVO/timer/UIKit callbacks to the main actor via assumeIsolated, add isolated deinits, and apply the few justified nonisolated(unsafe) escapes for queue-confined Apple APIs.
* Fix the unit tests for Swift 6 concurrency
Hop the waitForConfirmation body onto the caller's actor (Swift Testing runs confirmation closures off-actor), and adjust the affected suites and async signatures.
* offload diffs on concurrent threads instead of main actor
* make room info protocols sendable
* use a task group for fetching data so that everything runs concurrently in the TextRoomTimelineView when getting the preview.
* use the generic onMainActor implementation, which already makes a stream and send the continuation on the main actor.
* small pr comments issues being addressed
* update enterprise
* Update StaticCode to 1.1.0 and specify the required Swift isolation.
* fix ElementCallServiceTests
* update enterprise
* re-generate mocks
* update enterprise
* enterprise new code conformed to swift 6
