Quite an old question, but still. Hope it will be helpful for somebody. If I've got the author's question right, the idea is to detect whether the tap has began recognizing and to perform an action. Like if you don't want target to trigger only when the user releases the finger but already when he touch it for the very first time.

An easy way to do so is to make an extension for UITapGestureRecognizer like below:

fileprivate class ModTapGestureRecognizer: UITapGestureRecognizer {
    
    var onTouchesBegan: (() -> Void)?
    
    override func touchesBegan(_ touches: Set, with event: UIEvent) {
        onTouchesBegan?()
        super.touchesBegan(touches, with: event)
    } 
}

Later in your code you can use it like so:

let tapRecognizer = ModTapGestureRecognizer()
tapRecognizer.addTarget(self, action: #selector(didTapped))
tapRecognizer.onTouchesBegan = {
   print("Yep, it works")
}
yourView.addGestureRecognizer(tapRecognizer)

And you're awesome!
