Error "ld: library 'clang_rt.osx' not found" after upgrading to Xcode 15

After upgrading to XCode 15, when I run yarn tauri dev I am getting the following build failure:

  = note: ld: warning: ignoring duplicate libraries: '-lSystem', '-lobjc'
          ld: warning: search path '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/14.0.3/lib/darwin' not found
          ld: library 'clang_rt.osx' not found
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

it is looking for a version of clang that is not present, since I now only have 15.0.0:

ls -alh /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang
total 0
drwxr-xr-x   3 root  wheel    96B Feb  2 19:45 .
drwxr-xr-x  21 root  wheel   672B Feb 23 03:06 ..
drwxr-xr-x   5 root  wheel   160B Feb 23 03:03 15.0.0

How does Tauri determine which directories to put in the linker path?

Cleaning the target directory fixed it:

cd src-tauri
rm -rf target

I also ran a yarn upgrade before that to upgrade @tauri-apps/cli-darwin-arm64@1.5.9 to @tauri-apps/cli-darwin-arm64@1.5.11, but I don't think it made a difference.

Is manually deleting the target directory the best way to clean? I didn't see a cli option for this.

Yeah it is. You can also run cargo clean in the src-tauri folder, but it's virtually the same as deleting it yourself.

WDYT about adding yarn tauri clean to provide a consistent UX for yarn users? That was the first place I looked for it.

Let me know if you'd take a PR.
