Probably your server constant gets deallocated right after calling server.run() maybe you need to keep a global reference somewhere

well doesn't seems to work in Xcode 12.5... That's what the template holds .toolbar {             #if os(iOS)             EditButton()             #endif             Button(action: addItem) {                 Label("Add Item", systemImage: "plus")             }         } my bad I didn't see I had to change also the header and put everything in a navigationController

the biggest mistake I made was to activate iCLoud desktop and Document folder on my new M1 Mac. everything hangs forever impossible to delete files on desktop I have to go on iCloud web to remove file from the cloud then go command line style in the terminal rm -r and stuff that is really a big issue. poor performance
