Since nobody seem to have encountered the same issue with iOS 13, I'll try to re-formulate the question.
Regardless of the iOS version, how would you handle the Xcode configuration in order be be able to import .app files in the app?
(I mean the setting in the Document Types and in the Imported Type UTIs in the Info.plist / target settings)
have you found any solution? i facing the same problem.
Unfortunately I haven't found any solution yet.
I've even asked this on StackOverflow, but at the moment any answer yet.
What about you? Did you find anything yet?
