What fixes the error This version of Xcode isn't supported...
If the error message This version of Xcode isn't supported in this version of macOS frustrates you a lot or interferes with your normal use, let's resolve it with these methods below:
Method 1: Check macOS compatibility
Before diving into any updates or installations, the first step is to verify that the version of Xcode you're using is compatible with your current macOS version. Apple usually provides a compatibility chart that shows which Xcode versions work with each macOS version. For example, Xcode 16 beta requires a minimum of macOS 14.5.
How can we know that? This can be found in Apple's official developer documentation. By ensuring that your software is aligned with Apple's requirements, you can avoid unnecessary errors.
If you find that your macOS version/Xcode is outdated, updating either of them to the latest release is crucial.
- For macOS update: Apple menu > System Settings > General > Software Update, update it if there is something new.
- For Xcode update: App Store > Search for Xcode > Click Update if an update is available.
Alternatively, if you downloaded Xcode beta from the Apple Developer site, visit the site to download the latest stable release.
- Go to the Apple Developer website.
- Sign in with your Apple ID.
- Browse the More Downloads section to find older versions of Xcode.
- Download and install the appropriate version.
Therefore, remember not to open the new Xcode beta on an old macOS version~
Method 2: Uninstall and reinstall Xcode completely
In some cases, incomplete or corrupt installations of Xcode can cause compatibility issues. A full reinstallation can resolve these problems. To completely uninstall Xcode, simple deletion in the Finder or Launchpad is not enough. The related data will remain in the library, slowing down the performance of Mac.

- Finder > Applications > Utilities > Terminal.
- Enter xcode-select --install or open/Applications/Xcode-15.4.0.app/Contents/MacOS/Xcode then press the Enter key.
