It seems that this issue is related to Element’s ARC. I’ve tried equivalent objc code which works.

Sort of. performSelector says it’s returns an id, but in reality, it doesn’t in this case:

Also note this line:
The aSelector argument should identify a method that takes no arguments. For methods that return anything other than an object, use NSInvocation.

Indeed, performSelector is defined to only be safe for methods returning an object or void, afaik.

not even void.
