Can't drag down the View Controller

[sasan-soroush]

Hi Leo,
Hope you're doing awesome!
When I present the View Controller from popup bar I can't drag it down, I have seen similar issues on this repo but I couldn't find out how to resolve this issue,
I have a custom TabBarController & NavigationController, I don't know if it has to do anything with this issue,
Although it is working fine when I add it to new projects just for testing so I guess it is sth wrong with my project,
I wonder what can cause this behavior,

right now I just added a swipe gesture recognizer with .down direction to close the pop-up but I really like how it feels and looks on the original working version,

Also, The presented View Controller doesn't have any gesture recognizers when I try to print view.gesturerecognizers,
can it be related to this?

This is the core code for my custom tab bar controller:

class BaseTabBarController: UITabBarController {
    override func viewDidLoad() {
        super.viewDidLoad()

        let demoVC = FullScreenMusicPlayer()
        demoVC.popupItem.title = "Hello World"
        demoVC.popupItem.subtitle = "And a subtitle!"
        demoVC.popupItem.progress = 0.34
            
        self.presentPopupBar(withContentViewController: demoVC, animated: true, completion: nil)
    }
}

and this the View Controller that is being presented:

class FullScreenMusicPlayer: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        view.backgroundColor = .red
    }
}

Thanks in advance

Hello,
Have you overridden the viewForPopupInteractionGestureRecognizer property? That’s the only reason I can think of that would make it not work, since the controller in the video seems a simple one. Or disabled interaction with LNPopupInteractionStyleNone.

If you can create a small project where this reproduces, I can take a look why the gesture recognizer is failing. My instinct says user error, rather than framework failure, but I can at least give you an idea why.

I can reproduce your issue with a swipe gesture added. Have you removed that gesture from view?

[sasan-soroush]

Yeah, I just comment that out when I am trying to figure out what is going wrong,
at first, I assumed that maybe another library is adding another gesture recognizer but when I print all of them as you said, there is no other gesture recognizer.

Wait, just remembered from another discussion. Do you use Mixpanel? They add a gesture recognizer to the window (🤦‍♂️), which breaks the framework gesture recognition logic.

[sasan-soroush]

Wow finally we know why it was behaving like this, I was going crazy,
You're absolutely right, Mixpanel was the reason for this issue, do you know how should I deal with that ?

[LeoNatan]

Remove Mixpanel? I have no idea what it does, or why it has to add a gesture recognizer to the window. If you must use it, please open an issue with them. Thanks

[sasan-soroush]

Sure!
I feel relieved because of knowing what is wrong now!
I will talk to other developers to see if we can remove this or disable the gesture recognizer,
BTW, thank you so much for your patience and help ! that means a lot.
