When I attempt to launch an app from Xcode 11 (gm seed 2) to my attached iPhone running iOS 13 the I see the app launch with a white screen but then the iOS process hangs for about *60 seconds* before the app finishes launching. If I un-check "debug executable" on the target then this behavior does not happen. If I launch the app on the phone directly (without xcode) it launches normally. If I launch the app on the phone and attempt to attach the debugger from xcode I get the same (one minute) hang.
This only happens on one of my machines even though both are using the same setup (only diff is that one is a laptop and one is a desktop). So I am assuming something is wrong or corrupted with the "debug support" that was installed on first connect to the new xcode... But I can find no reference to how to re-init that. I have tried the "unpair phone" option in devices in xcode but it does nothing. I don't see anything in settings related to developer profiles or debug symbols.
Anything I can do to reset the phone with respect to debgging support / symbols installed by xcode? Any other thoughts?
