My computer setup is I work from an account with regular (non-admin) privileges. I login into the admin account to install apps, update the OS, that kind of stuff, but work is from the reduced privileges account. And, when in it, I cannot preview swiftUI views in Xcode. Incredibly frustrating, have tried everything including a complete wipeout of the disk and reinstall, but no luck. Don't have any iOS simulator targets installed, it's macOS target I am working on. If I fire up xcode from the admin account it's all good, previes work and so on. Not so in the non-admin account, consistenly getting the Cannot preview in this file. Failed to launch xxxx Also tried elevating the privileges of the account to Admin, rebooting, no luck. Tried creating a new account, non-admin or admin, no luck. The detailed error repeats something along the lines of: == PREVIEW UPDATE ERROR: GroupRecordingError Error encountered during update group #3 ================================== | FailedToLaunchAppError: Fail
