+## Xcode version can't be located
+
+In some scenarios, building a .NET MAUI app on iOS or Mac Catalyst may attempt to use an Xcode version that's no longer installed. When this occurs you'll receive an error message similar to:
+
+```
+xcodebuild: error: SDK "/Applications/Xcode_14.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk" cannot be located.
+xcrun: error: sh -c '/Applications/Xcode_14.1.app/Contents/Developer/usr/bin/xcodebuild -sdk /Applications/Xcode_14.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -find dsymutil 2> /dev/null' failed with exit code 16384: (null) (errno=Invalid argument)
+xcrun: error: unable to find utility "dsymutil", not a developer tool or in PATH
+```
+
+In this scenario, you should update the *~/Library/Preferences/Xamarin/Settings.plist* file to specify the version of Xcode that's installed on your machine.
