You can always switch back to one of the stable XCode versions during this time. While we aim to prioritize all the issues that might occur with this version to improve the stability of our platform continuously, this is still an experimental release, and we can not guarantee quick resolution times. If you decided to use this version and ran into any problems, we’d appreciate it if you could raise the matter with our support team.

Also, when the experimental label is removed, your build targets using “XCode 13.3.1 (Experimental)” will keep using the stable “XCode 13.3.1” version and not the “Latest Compatible Version”. To use this experimental version, you need to specifically select it as your XCode version, as the “Use Latest Compatible Version” option will set the latest stable version. This will enable you to build projects needing this version and help us prove it stable before the general availability. That’s why we decided to release Xcode 13.3.1 under an 'experimental' label for a few weeks. Still, given the nature and diversity of projects built using Unity Cloud Build, we prefer to release XCode 13.3.1 under the experimental label for a few weeks before setting the majority of the users to use this version automatically.

We’ve been working hard to support version 13.3.1 of XCode for the past months. We understand that having the latest XCode version is critical to your success. We sincerely apologize for the unexpected delay in launching XCode 13.3.1 due to several unforeseen issues.
