What's Changed
- Broaden the
swift-syntaxdependency range to600.0.0..<605.0.0, allowing SwiftSyntax 603.x and future 604.x releases while preserving the existing SwiftSyntax 600.x compatibility window. - This improves package resolution for Xcode 26.6 / Swift 6.3 and leaves room for Xcode 27 / Swift 6.4 prerelease toolchains.
Validation
swift testpassed with Xcode 26.6 / Swift 6.3.3.
