How to attach debugger to iOS app after launch?
I'll leave this here since neither of the other 2 answers gave me quite enough detail without a little bit of a struggle.
Run your app in the simulator and take note of the name in the Debug navigator
Plug in your device and don't forget to select your device as the target
- Debug > Attach to Process > By Process Identifier (PID) or Name
- Enter the name from step 1 and attach. That should be all you have to do.
- Attach your device connected your Mac
- Debug > Attach to Process by PID or Name
- In the dialog sheet, enter the name of your App as it appears in the
Debug navigatorwhen started via Xcode (e.g. Target's name not bundle-id).
If the app is already running, the debugger will attach to the running process. If it isn't running, it will wait for the app to launch and then attach.
