Fixes a crash in MeshGL.originalIDs when built with Swift 6.4 (Xcode 27 beta). The bug is in Swift itself (swiftlang/swift#91375); this release avoids the pattern that triggers it. Swift 6.3 (Xcode 26) and earlier are unaffected.
If you reach this through a package that depends on Manifold-Swift, run swift package update to pick up the fix.
