Another… easy fix.
Could not locate installed application
Whenever I receieved this frustrating error when trying to debug my app on a live device, it kept frustrating the heck out of me… until I realised that I’d forgotten to turn back on Automatic Signing in XCode.
I usually leave it off for Fastlane, which does all my certificates n such for me, but yeah this wasn’t exactly the most… forthcoming error to have.
Hope it helps someone.
