There is a property on the UIGestureRecognizer class called "cancelsTouchesInView" which defaults to YES. This will cause any pending gestures to be canceled. The Pan gesture is getting recognized first since it does not need to have a "touch up" event, so it cancels the Swipe gesture.

If you want both gestures to be recognized, try adding:

[yourPanGestureInstance setCancelsTouchesInView:NO];

You can call them in parallel by implementing the following method of the UIGestureRecognizerDelegate protocol:

- (BOOL)gestureRecognizer:(UIPanGestureRecognizer *)gestureRecognizer 
shouldRecognizeSimultaneouslyWithGestureRecognizer:(UISwipeGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

Use requireGestureRecognizerToFail: to recognize the gesture if the other gesture recognizer did not executes.

[rightSwipe requireGestureRecognizerToFail: panGesture];

A swipe and a pan gesture can not be recognized at the same time because a swipe gesture is just a special type of pan that has to be faster, short lived, and in one direction.

What you should do is setup the pan gestures to require the swipe gesture to fail before they can start. You will need to set each of the UISwipeGestureRecognizer to be a requireGestureRecognizerToFail on the UIPanGestureRecognizer

override func viewDidLoad() {
    super.viewDidLoad()

    let swipeGestures = setupSwipeGestures()
    setupPanGestures(swipeGestures: swipeGestures)
}

private func setupSwipeGestures() -> [UISwipeGestureRecognizer] {
    let swipeUp = UISwipeGestureRecognizer(target: self, action: #selector(self.handleSwipes))
    let swipeDown = UISwipeGestureRecognizer(target: self, action: #selector(self.handleSwipes))

    swipeUp.direction = .up
    swipeDown.direction = .down

    circleView.addGestureRecognizer(swipeUp)
    circleView.addGestureRecognizer(swipeDown)

    return [swipeUp, swipeDown]
}

private func setupPanGestures(swipeGestures: [UISwipeGestureRecognizer]) {
    let panGesture = UIPanGestureRecognizer.init(target: self, action:#selector(self.handleThePanUp))
    for swipeGesture in swipeGestures {
        panGesture.require(toFail: swipeGesture)
    }
    circleView.addGestureRecognizer(panGesture)
}

Thanks for the tip . I have another Tap gesture that i use just once in order to increase the size of the view. Do you think it will conflict with the UISwipeGesture and the UIPanGesture ? Can I setup the speed of the pan so that it increases the counter in a slowly manner ?

Tap shouldn't interfere. You could set it up so the counter is increased when you pan x points so as you pan, it can increase more than once.

Should I set up the speed in the extension of the UIPanGesture ?

You would handle that in handleThePan: by checking for how far the pan has moved and updating your counter the appropriate amount.

By definition, a swipe gesture is necessarily also a pan gesture -- both involve translational movement of touch points. The difference is in the recognizer semantics: a pan recognizer looks for the beginning of translational movement and continues to report movement in any direction over time, while a swipe recognizer makes an instantaneous decision as to whether the user's touches moved linearly in the required direction.

By default, no two recognizers will recognize the same gesture, so there's a conflict between pan and swipe. Most likely, your pan recognizer "wins" the conflict because its gesture is simpler / more general: A swipe is a pan but a pan may not be a swipe, so the pan recognizes first and excludes other recognizers.

You should be able to resolve this conflict using the delegate method gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:, or perhaps without delegation by making the pan recognizer depend on the swipe recognizer with requireGestureRecognizerToFail:.

With the conflict resolved, you should be able to simulate a one-finger swipe by quickly dragging the mouse. (Though as the mouse is more precise than your finger, it's a bit more finicky than doing the real thing on a device.) Two-finger pan/swipe can be done by holding the Option & Shift keys.

Nice answer. But I don't think the pan gesture wins because it's more general, but rather because it's a continuous gesture (where a swipe is a discrete gesture) so a pan is recognised before a swipe. The swipe is only recognised on the finger being raised, the pan is recognised almost immediately after the finger starts moving. Swipe vs. Pan is covered well in the Event PG under "Declaring a specific order for two gesture recognizers".

Swipe Gesture will work when you drag your finger only in certain directions (swipe up,swipe down,swipe left, swipe right). For example swipeable cells in table view controller. Pan Gesture will work when you drag your finger in any directions. You can give acceleration or deceleration to it. FOr example, moving a object from one place to another place or spinning a spinner..

Short and sweet.

I like this explanation; clarify the point in a short English.

UIGestureRecognizerDelegate
gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:

method might be useful. If you simply return YES from this method, both gestures can be recognized at the same time, so you can respond properly to both.

recognizing simultaneous gestures does not give me the desired behavior that i am aiming for. swipe left supposed to move UIView from one location to another and pan gesture moves it as well but based on your touch panning and velocity. thanks.

It sounds like the pan recognizer can let you move the view with your touch, but then if a swipe is detected, you can set a flag telling the pan to stop working, as the swipe behavior will take over. Do you think that might accomplish what you're trying to do?

that's a great idea and it is what i am trying to achieve, is there a simpler implementation without writing or overriding your own touchesBegan, Moved, Ended methods to flag and let the current gesture stop and pass to the next gesture behavior? thanks.

Yes, what I'm suggesting is to keep your gesture methods, return YES from that delegate method I mentioned, and then have an internal class property (a BOOL should be enough, I think) like didSwipe. In the beginning of your swipe recognizer method, set it to YES - this will only happen when a swipe is recognized. In your pan method, wrap the whole thing in an if statement: if (!self.didSwipe) {...}, so this part will only be executed if there wasn't a swipe or hasn't been a swipe yet. You may need to also take care of resetting that variable at some point.

thank you for your suggestion, i think the solution will work. will implement it and see if i can get the desired behavior.

You can use the UISwipeGestureRecognizer state and can do as what you want. Have a look on the following code,

- (void)swipeGestureMethod:(UISwipeGestureRecognizer *)recognizer {

   CGPoint point = [recognizer locationInView:[recognizer view]];
   if (recognizer.state == UIGestureRecognizerStateBegan) {

   } else if (recognizer.state == UIGestureRecognizerStateEnded) {

   }

    myView.center = CGPointMake(lastLocation.x + translation.x,

Well, I figured out the answer to my own question. Not sure if this is the most efficient/cleanest way to do it, but it was the only way to get the desired effect. Here is my solution: In my overlayView, I overridded

override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
    if miniView.frame.contains(point) || miniView.isOpen {
        return true
    }
    //pass the tap onto other views
    return false
}

This basically allowed me to say if the view should have userInteraction, which I based upon certain criteria (the tap was inside my miniView or the miniView had enlarged). But, when I return false, then it would let the touch pass through. If you do not have this method overrided and the overlayView had userInteractionEnabled, then the overlay view would literally eat all the touches. With this method, I am able to still keep the userInteractionEnabled on the overlayView, but decide when the touches should pass through to somewhere else.

Then, in my parentView, I added a pan gesture. I made parentView a UIGestureRecognizerDelegate, and implemented this function:

override func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
    //if the final page is the first page (i.e. the user only has one pic), then we don't want swiping that could interfere with the card swipe.
    if let pan = gestureRecognizer as? UIPanGestureRecognizer {
        let velocity = pan.velocity(in: self)
        let isVertical = abs(velocity.x) < abs(velocity.y)
        let isUpwards = getPanDirection(velocity: velocity) == .up
        return (theBumbleScrollView.isAtFinalPage && isVertical && isUpwards) || theBumbleDetailView.isOpen
    }
    return true
}

This allowed me to see when the pan gesture was about to begin, and depending on what I return (true or false), it would change the state to .failed for the pan gesture. Basically, canceling it the gesture. This is a helpful Stack OverFlow post on this: Limit UIView movement to only vertical or horizontal axis

Now, my pan gesture was failing according to my specified criteria, but I needed to tell my scrollView that its pan gesture could get to panning, if my custom pan gesture had failed. That is where this handy line came in require(toFail: ...):

let pan = UIPanGestureRecognizer(target: self, action: #selector(self.isPanning(pan:)))
    pan.delegate = self
    self.addGestureRecognizer(pan)
    theScrollView.panGestureRecognizer.require(toFail: pan)

When I set the pan gesture onto the parent view, I basically told the scroll view's pan gesture (which apple built in automatically) that it should be next in line should custom pan gesture fail.

That was the solution that allowed me to sometimes scroll on my scrollView but other times be able to scroll upon my overlayView. Hope I can save someone the day that it took me to figure this out. I also created a github repo of my sample project (names of views are different), if anyone would like to see the sample code. https://github.com/danielchangsoojones/Bumble-App-Clone/tree/master

Assuming you have some other handler implemented for the pan gesture, can't you just do:

this could work but handlePan (with its own implementation of touchesBegan, Moved, Ended which is a bit complex for a noob) is actually on a different library being used on view controller. thanks.
