This is a joke... we are starting with one file the ContentView, and the guy says, just by sharing on iCloud it adds some new things... Not in here... and suddenly the app has 3 new files inside, and no idea what are inside these...: AssistantTab, TeasTab, TeasWheelView... Thats a real weird way to teach...

Just use 'Apple Configurator' instead of Xcode to install on your device and it's working.... until Apple fix this and so many other bugs...

15.3 still the same problem... you download a container, you then replace the container with the one you just downloaded, and it will give this error ... wanted to modify an element in it, (restore an older more complete Db, but not possible anymore as it was in some earlier version... so I try to just download, and reupload, replacing, but its not working... Apple always more buggy....
