[BUG] ".framework" tweaks injecting not work

[user919722]

I‘m having trouble injecting the .framework part of a tweak into apps via LC‘s tweak page (the tweak was specifically designed to work on jailed devices).

I‘ve attached what exactly I am injecting and what the framework looks like as images below.

First, I simply tried extracting the dylibs + framework from the .deb file, which resulted in the following error:

I managed to fix that by changing the dylib‘s paths to @rpath. I also included libsubstrate.dylib. I can confirm that the dylib-part of the tweak successfully loads in now.

However, the .framework part still doesn‘t load in. I‘ve tried deleting every dylib from the tweak folder (even libsubstrate) and then tried opening an app to see what error I would get. I didn‘t get an error message similar to the one above (no error at all actually). The same happens if I delete everything but the framework and libsubstrate.dylib: no error message and the app loads in like no tweaks are injected.

Now I‘m kinda at a loss. I didn‘t change anything about the .framework part of the tweak (simply copy pasted it from the .deb). I‘m using LC 3.2.0. Can LC not load any frameworks as tweaks or am I doing something wrong?

Any help appreciated!

Yes, this is a bug, I'll fix that soon. However it is unlikely that tweaks with assets will work with LiveContainer's tweak loader due to file location issues even if they are designed for rootless environment. It's recommended to directly inject the tweak to the app itself.
