Claude, thanks for your feedback and advice. I deinstalled Xcode completely from my iMac and reinstalled XCode from the AppSore. After installing, I went back to my project and it seems Xcode has a problem with the simulator iPhoneXS with I normally use due to my device. After selecting the iPhone13 in the Canvas it looks ok. I will test this if I have time to code. I keep you updated, it this possible or a strange observation? Gerd

If I go back to the latest Xcode 12…. Will this help for an interim solution? Thx
