I have facing this issue while trying to launch the app on iPhone. Any clues?
LogPlayLevel: Instruments Usage Error:
Unknown device specified: “”LogPlayLevel: ERROR: Launch Failure
LogPlayLevel: RunUAT ERROR:
AutomationTool was unable to run
successfully. PackagingResults: Error:
Launch failed! Failed to launch on
device. Make sure your install of
Xcode matches or is newer than the OS
on your device.
It was running fine and then I tried to run on another device but I got this issue and when I tried to use the same device again, the issue persisted.
OS: Mac
Environment: Xcode and UE4.18
