AFAIK https://github.com/rust-lang/docs.rs/issues/1957#issuecomment-1365862227 is still correct, there is no way we can ship the necessary sdk to properly support cross-compiling to apple targets. You will need to either avoid the objc_exception dependency when building on docs.rs or get them to detect docs.rs and skip trying to build the C code.

this sounds like

the actual solution is #1957 (building on target platform + necessary SDKs)
until then, the crate authors can make the crate build via cross compilation with conditional compilation.
