Good question @Blackjacx . I was using it only for pure binaries so haven't that case. You have to verify that, but it could work since there are two recursive copies of framework made and only binary and Info.plist becomes modified.
Do you know what I can do if the framework doesn't have an Info.plist file?
I can't remember if I had such a case but I believe you should make one by hand inside (skip plist step and make it manually after merge). I am not sure if that also applies to static binaries, those could have no plist, so it should work without it.
Hello there, so I recently had to convert openCV2 ncnn and openmp and I ended up creating a new working script, it looks like this:
#! /bin/bash
find "." -name '*.framework' -type d | while read -r FRAMEWORK

What when the framework contains resources? Are they also transferred to the XCFramework? Cannot see any references.
