2.4.3

Fixes

• Fixed a launch crash on older iOS runtimes when built with Xcode 27. Explicitly constructing TupleView in the legacy blur-background fallback prevents unavailable TupleContent metadata from entering the container's view type. (#22)
• Preserved the existing gray warning background and its content on iOS 14, macOS 11, and tvOS 14.

Verification

• Existing XCTest suite: 94 tests passed with no failures (swift test -q); the Swift Testing runner also reported 3 passing tests.
• Independently reproduced the original launch crash on an iOS 18.5 simulator using Xcode 27.0 (27A266a). The patched host reached its rendering callback and remained running.
• Confirmed that the patched iOS 15-target executable has no undefined TupleContent references.
• Confirmed that the modified background code compiles for an iOS 14 target. Legacy-runtime rendering, other platforms, and physical devices were not runtime-tested in this verification.

Thanks

• Thanks to @JoshHrach for reporting the Xcode 27 / older-iOS launch crash, diagnosing the unavailable TupleContent reference, and proposing the initial fix in #21.
• Thanks to @gewill for the compatibility-preserving fix in #22 and the accompanying integration validation.
