I am creating an application extension (appex), to be precisely, a smartcard extension, my question is,

can an appex contain a Frameworks folder with a dylib in it?

like, sample.app/Contents/Frameworks/mylib.dylib

I woul like to load a dylib from there.

Is it possible or allowed to do that?

sample.app/Contents/Frameworks/mylib.dylib

That definitely works.

On macOS putting the dynamic library inside the appex should work as well.

IMPORTANT iOS is more strict about this stuff. Specifically:

iOS does not support third-party dynamic libraries. If you need this you have to wrap the library in a dummy framework.
iOS requires that such frameworks be embedded in the top level app.

Neat-o!

I don’t know but, even if I did, I’m not allowed to discuss The Future™. As always, if you’d like the system to do something that it doesn’t currently do, you should file an enhancement request describing your requirements. Please post your bug number, just for the record.

I have seen that CryptoTokenKit is open for public use on IOS starting from iOS 13 and Xcode 11, which is a good thing.

Not sure whether it will work also with usim. Somebody tried this?
