I think there was some kind of change in the way the IPA packages were built in 4.22. My IPA are all around that size, but after submitting to the app store, testflight delivers reasonable app sizes (70 - 90Mb) for my app. I haven’t looked into it properly, but rest assured the size appears to be okay, just a different delivery package of some kind.
For the crash on phone, clear your projects build / binary / intermediate and saved folders. Any old build data from 4.21 may interfere with what you end up packaging. Backup your project first (of course) and mind out for the folders containing your icon/splash image resources unless you want to add them into the project again.
The following works for me in some situations like that.
- delete Saved, Intermediate, Build and Binaries folders
NOTE: One (or more) of these folders contains the configured splash screens and icons for the project. After deleting you will need to add them again manually (errg). Check which folders when you attempt this. I have taken to leaving these image resources/folders in place and deleting the other files.
