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

I had this same issue when loading a bunch of very large images (5000px x 5000px) in UIImages. Luckily the images were not supposed to be anywhere near that big and I just needed to resize them.
