Xcode 26's macOS 26 SDK automatically imports _DarwinFoundation modules, which are incompatible with Embedded Swift mode. This causes build failures with errors like: error: module '_DarwinFoundation1' cannot be imported in embedded Swift mode This fix explicitly sets the target to arm64-apple-macos14 in the simulator toolset, which avoids the macOS 26 SDK's implicit Foundation imports while still producing a working simulator binary. Changes: - Add swiftCompiler section with explicit target and flags to disable implicit module imports - Add explicit target to cCompiler section Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
