Two things to look at. Did you turn on more than one architecture to compile (armv7 and arm64 together)? It works for me (and or build machines use this to make both sets of libraries and so files), but that may be part of the problem. Also, try deleting the contents of Binaries, Intermediate, and Saved in your project’s directory and load the project in the editor and try packaging again; maybe something got messed up.
