I think I got it, I needed to add this let dest = documentsURL.resolvingSymlinksInPath() Thanks.

I tried it two ways, let documentsURL = try fileManager.url(for: .downloadsDirectory, in: .userDomainMask, appropriateFor: nil, create: false) // and let path    = NSSearchPathForDirectoriesInDomains(.downloadsDirectory, .userDomainMask, true)[0] as String let documentsURL     = URL(fileURLWithPath: path)

I think you misread my query.

Submitted. Thanks.

It's not that it trying to install an old version, but MacOS 13 SDK. The question is why it can't stop doing this.

Problem is solved. Xcode is looking for an non-existent symlink. There is no "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.0.sdk". Instead, there is drwxr-xr-x 8 maurice staff 256 May 28 00:43 MacOSX.sdk lrwxr-xr-x 1 maurice staff 10 May 28 00:16 MacOSX13.3.sdk -> MacOSX.sdk lrwxr-xr-x 1 maurice staff 10 May 28 00:16 MacOSX13.sdk -> MacOSX.sdk When I manually added the symlink lrwxr-xr-x 1 maurice staff 10 May 28 00:44 MacOSX13.0.sdk -> MacOSX.sdk Everything started working again.
