Cannot open with Xcode version 15.4

[longbow007]

The alert says:
cannot be opened because it is in a future Xcode project file format. Adjust the project format using a compatible version of Xcode to allow it to be opened by this version of Xcode.

Oh, sorry. I developed it using Xcode 16.0.0 Beta 6, and I'll handle it later. If you're interested, feel free to submit a PR to fix it.
