It is possible, I was doing it before Objective Pascal was created.
Just use the functions in the objective-c runtime, read:



But I warn you that doing this is a terrible choice. Objective Pascal
is the way to go. I've been working in Objective Pascal in the LCL
Cocoa interface and it's pretty good IMHO. But if you are masochistic
you can use the runtime instead of Objective Pascal.

The Cocoa interface is advancing fast. I am even running out of known
bugs, so other people testing would be appreciated.

I don't see how Lazarus would break cross platform. That's a wierd statement.

You got the order inverted here. It is not FPC/Lazarus that are less
Apple friendly. It is Apple that is each time less Pascal friendly,
and for that matter also each time less C/C++/Java friendly. Apple
wants you to use Swift (or whatever it's called).
