Crash on - [ResponsiveLabel performActionAtIndex:] in swift 3.0

[davehenke]

Perhaps I'm defining my closure wrong, but when defining a closure to work with a responsive label, the subsequent action execution attempts to pull a closure out of self.textStorage at memory address 0x00000

In this example, cell.containedView is a ResponsiveLabel, and hashtagResponder is an ivar defined as:

fileprivate var hashtagResponder: PatternTapResponder?

hashtagResponder = { [weak self] hashtag in
    if let strongSelf = self, let hashtag = hashtag {
        strongSelf.delegate?.didTapHashtag(name: hashtag, storySectionController: strongSelf)
    }
}
cell.containedView.enableHashTagDetection(attributes: [NSForegroundColorAttributeName : UIColor.primaryBrand, RLTapResponderAttributeName : hashtagResponder! as AnyObject])

(lldb) po tapResponder
0x0000000000000000

This is not a reuse issue, because the controller that owns the PatternTapResponder is still in memory.

Any help is appreciated.

Even when removing the dependency in the closure on self (just calling print(hashtag)), which should limit the closure to acting on a String and therefore remove the need to mark my class definition as @objc, it still does not appear to work. Even marking my controller as @objc and moving the closure from an ivar to defining it inline, I can't get it to work.

let hashtagResponder: PatternTapResponder = { string in
    print("test")
}
cell.containedView.enableHashTagDetection(attributes: [NSForegroundColorAttributeName : UIColor.primaryBrand, RLTapResponderAttributeName : hashtagResponder as AnyObject])

I am having the same issue with Swift 4
