Linker Error

[atrt7]

I fixed the compilation issues by doing #import <Foundation/Foundation.h> in some files. now I get a linker error

Undefined symbols for architecture armv7:

probably has something to do with @available only working on macOS (sigh...), there is a possible fix for it here: theos/theos#380

make sure you have a 13.0 sdk in $THEOS/sdks or change the sdk used here https://github.com/opa334/AltList/blob/main/Makefile#L3
