Other than this info:
Is there any other definitive list (as of UE4.12) that describes specific ways to reduce the packaged ipa size as much as possible?**
I am currently using PakBlacklist-Shipping.txt and have excluded unrquired plugins.
The current TappyChicken version downloaded from the AppStore today is 67MB
https://itunes.apple.com/gb/app/tappy-chicken/id821841075?mt=8
However, if I repackage the Tappy Chicken project with optimisations I can never get it below 94MB.
I have seen Michael Noland’s comment about optimising Tappy Chicken down to 28MB (which is probably no longer valid), nonetheless, I don’t know how this was achieved.:
