iOS app crashes, xcode says 'Lost connection to X's iPhone' when debugging

Question

My app crashes and I need some advice to find and fix the problem. It is not a device or cable problem because it happens with all devices and not only when debugging. Xcode

Answer 1

Just to add that I had the same issue running my app both on and old Ipad 3 and Iphone 6. What ended up being the problem was I had accidentally saved 2 images of the project as a 40mb and a 20mb version. So it was a memory issue. I downsized them as 1mb each, and issue solved.
