Thanks for tagging me!
The ObjFW runtime itself does not contain anything about release, retain or autorelease - these are all part of ObjFW (as in the framework). As ObjFW also supports the Apple runtime, as well as mixing with Foundation code, it so far only provides objc_retain and objc_release when they are missing, to make ARC work. They just call into the corresponding methods on the object and do nothing else.
How will this change work from the Apple runtime? Will objc_retain/objc_release call the retain/release on the object if it implements its own? Should I drop my own retain/release implementation from my root object if I am compiling against the Apple runtime?
I'm mostly concerned about mixing ObjFW and Foundation code while using the Apple runtime here. ObjFW with the ObjFW runtime and no Foundation is easy to change.
