Single vs Double Tap

    I am trying to have two distinct actions: single tap and double tap (two quick taps). What happens though is that both actions get called. Is there a way around this?

    Drop 2 TapGestures and in the double ones set "Taps Required" to 2 in the Inspector.

    Hi @marco. I did this already but when I double tap (at least in the simulator), it also triggers the one tap Action event.

    Also, the one tap conflicts with swipe up for instance, as swiping requires tapping and swiping.

    Any solution?

    Hi @ingurgite
    we'll do our best to add a way to fire a gesture (in your case the single-tap) only when another gesture fails (in your case the double-tap) in the next release.

    A new function for the gesture recognizer objects, named requireToFail(), will be available in the next release.
    You will be able to add the following code in the WillShow event of the container of the two tap gestures:
    (where TapGesture1 is the single-tap and TapGesture2 is the double-tap)

    Thanks a lot @andrea. Out of curiosity, when do you think the next release will be out?

    @ingurgite, the new official release will be available in about two weeks.
    In the meantime, you could try the new beta release that includes this new method:
    Creo build18340

    Thanks Andrea. It works. It's great.

    However, this beta version crashes every time I stop the simulator :(

    Hi @andrea, I am coming back to you as it seems the requireToFail() functionality is not yet in the stable release. Can you confirm or did something change?

    Hi @ingurgite , the `requireToFail()` method is included in the newly released version and it is documented in the superclass documentation: UIGestureRecognizer
