Hey @DTS Engineer thanks for your reply. I am using the release version, no Beta. Xcode Version 26.2 (17C52) Simulator iPhone 13 mini, iOS 18.5 Version 26.0 (1062.1) SimulatorKit 954.5 CoreSimulator 1051.17.7

I have the same issue with XCode 16. I assume that Apple does that on purpose to remind people to download the latest iOS Runtime. But it feels very buggy and took me some time to solve.
