I built my project for iOS and on the iPhone the App Icon is not showing the way it should be. It looks like an empty sketch, check the screenshot attached.
The image is a simple 128x128 png file which worked on a former project. The weird part is, that right after building it on my iPhone via Xcode, the Icon at first is shown normally, but then after a few moments the Icon changes to the sketch attached. In the settings of the iPhone, where you have every app listed, the icon appears normally! Also in Xcode the Icon was looking normally. Does anybody have the same issue? What is wrong?
The last time I published an iOS app was about 6 - 7 years ago ^^. However I do remember that for iOS you HAD to provide the icons in all available resolutions. So it wasn’t enough to provide one icon. That’s probably because Apple always demands a high quality standard. They never scale down a larger icon if they need a smaller one. You have to provide the lower resolution versions yourself.
Note that this is just from my memory and just reflects the issues we had 6+ years ago. Things might have changed, but it’s the first thing you should check.

The second answer was the solution. Have to set the Location to “Relative to Project”.
