@Claude31 Unfortunately I need my code to be performed before the orientation animation happens, not when it already completed.

Anyone?

Please I appreciate any general suggestion

By further investigation it looks like hitting >800MB in size, even split across multiple .xcassets files, immediately triggers the error. Though, I couldn't find anything mentioning an hard limit on assets file size, only thing I could find was <=4GB cap on bundle size, which I don't even remotely hit.

@DTS Engineer This is the whole error by the way: CoreUI: Error: unable to add asset to store *** Terminating app due to uncaught exception 'IBPlatformToolFailureException', reason: 'The tool closed

@DTS Engineer creating an empty project and copy/pasting the assets catalog does indeed reproduce the issue, the problem is that such catalog contains over 3k files total and its size is around 1.2GB, I don't think one can attach samples that large. Of course in that 1.2GB there are assets that do not contribute to the issue, and I'm trying to slowly find a minimal set of assets that causes the issue to appear. Apple Support seems to require at most 50MB which is basically impossible for the scope of the project. The issue appears with every version of XCode, it just fails with this error when building with Archive scheme, but runs and builds fine if a simulator or physical device is selected.

@DTS Engineer I ended up moving part of the images from the assets catalogs to the bundle files, that is, I just dragged around 700MB of images under the project folder, and was then able to compile and send to the App Store. It looks like images were not corrupted so it wasn’t a problem with images. Still don’t know what caused it, my best bet is that the OS kills the process after it drains the CPU (it goes to 100% usage on all the mac I tried) for about 140 seconds.
