Can you add the target to the CI and local dev?

@Thomasdezeeuw do you mind if I use target_env = "apple" ? Instead of changing this every time Apple releases a new device

I think that is deprecated. Or was that target_family?

target_vendor is being deprecated: https://github.com/rust-lang/rust/issues/100343. For now let's stick with explicit OS, I don't really want to deal with all the target stuff a the moment, at least we know that this works.

target_vendor = "apple" will not be deprecated unless an alternative appears, see https://github.com/rust-lang/rust/issues/100343#issuecomment-2065159934, so I think you can safely use that

Let's still go with target_os for now, we'll let the dust settle on vendor vs. family vs. os, etc. first.

@Thomasdezeeuw do you think that we can merge ?

[Thomasdezeeuw]

I want to merge #520 first, then it's a lot easier to add new targets.

[Darksonn]

520 has been merged now.
