Found multiple versions of Xcode in /Applications/ error

Updated over 3 weeks ago

Issue

A build using fastlane can fail with the following error message:

Build failed to compile with Xcode-14.2 - Found multiple versions of Xcode in '/Applications/'

Possible solutions

Our Xcode stacks can indeed contain multiple versions of Xcode but in most cases, this should not cause a problem. If the error occurs, we recommend checking the full log of the xcodebuild command. To do so, turn off xcodebuild_formatter in fastlane, or export the logs as a build artifact. The actual root cause will be visible in the log and that is absolutely needed to debug this issue. Please enable verbose logging within the step as well.
