This may be associated to the issue I am seeing with Selections on CollectionView

[https://github.com//issues/10160]

This is critical. I guess I should not be to hasty in updating my Mac to the latest version. But now I am stuck and can't release my app due to Gesture Recognizers not working.
Hopefully a fix will be released soon.

lhughey · 2020-04-01T16:04:33Z

YES. This is a critical error that shouldn't have made it past UI smoke tests. All of my gesturerecognizers in iOS are broken, across multiple projects.

I'm also using
Mac Catalina 10.15.4
VS2019 16.5.2
Xamarin VS package 13.6.0.11
Xamarin.Forms 4.5.0.495
Xcode 11.4

EvanMulawski · 2020-04-01T18:04:13Z

May be due to this new delegate method on UIKit.UIGestureRecognizerDelegate:

gestureRecognizer:shouldReceiveEvent:

chamons · 2020-04-01T18:42:37Z

Appears related to xamarin/xamarin-macios#8255 and @dalexsoto is running it down there.

Fixes xamarin/Xamarin.Forms#10162 Fixes xamarin#8255 Xcode 11.4 introduced a new protocol member to `UIGestureRecognizerDelegate` and our initial proposed default value for `ShouldReceiveEvent` is not playing well with the world.

InquisitorJax · 2020-04-01T19:01:16Z

Pretty easy to repro: just create a new Master Detail from the template, run the iOS app.
None of the items on the main page with navigate through to item detail because of the broken tapgesturerecognizer behavior.

dan5602 · 2020-04-01T19:04:26Z

@InquisitorJax - Looks like the issue has been found and fixed already - well at least in macios

chamons · 2020-04-01T19:05:51Z

Fix is in PR, once we get a package we will validate. We believe we have this sucker pinned down.

InquisitorJax · 2020-04-01T19:06:51Z

@chamons that's great news - what does the release eta look like - I would imagine very many people who upgraded are now dead in the water because of this :(

rezamohamed · 2020-04-01T19:25:55Z

I literally wasted so much time with the Mac OS upgrade and Visual Studio not syncing and now for the past day dealing with this thinking it was my code. Pretty frustrated with Xamarin right about now...I am just venting. Sorry!

ezavil · 2020-04-01T19:31:41Z

In a physical device with 13.3 OS it seems to work correctly, in the simulator with version 13.4 it fails...

The update works. Thanks Xamarin Team

dotMorten · 2020-04-08T03:48:44Z

Can also confirm the reproducer I listed above now works, so the ArcGISRuntime Map controls are back in working order

taublast · 2020-04-08T06:31:30Z

Lastest vs 2019 16.5.3 installed xam ios 13.16.0.13 but can't test as provisioning profiles and certificates are not received from mac anymore and are not listed in VS dropdowns on windows. Did not have this problem with previous VS version. I have xcode 11.4.
Is it by design and we have to setup all apple accounts on windows now? I have a feeling it checks only apple accounts on windows and shows nothing instead of syncing them from mac.. Created an apple account on Windows as a workaround.

OMG UPDATE this is by design: https://developercommunity.visualstudio.com/comments/962872/view.html

Even more <Image> stopped showing remote images on iOS with this update. SIlly replacing with ffimageloading <CachedImage> as a workaround.. I feel at times of forms 3 and below when was spending more time fighting framework bugs than creating an app.. Sigh

InquisitorJax · 2020-04-08T06:47:17Z

@taublast I think that's a separate issue. I had it with the 16.5.2 update, but this update worked fine. I had to provision new profiles to get it to work again.

mshwf · 2020-04-08T07:34:50Z

@taublast this happens with me a lot. And I have to restart Visual Studio /Mac/ Windows/ re-install the provisioning profiles.. , to get them back in Visual Studio. Sometimes they don't, and I have to build on Mac.

myonlinegolfclub · 2020-04-08T12:57:58Z

The update works. Thanks Xamarin Team

CNBoland · 2020-04-08T14:03:16Z

Delete Obj / Bin Folders, clean, rebuild solution and try closing / opening VS.

What have you tried ?

odapplications · 2020-05-07T21:08:09Z

Does not work on physical device. Strange how some tap gestures work on ios but not all. All work fine on android.

odapplications · 2020-05-09T00:36:43Z

Ios 13.3 it was not working when set in xaml. But in the .cs file it seems to be working. Using latest xamarin forms.

wocar · 2020-05-23T06:04:35Z

It doesnt work for me, now with iOS 13.5.

I upgraded visual studio to the latest libraries and now works. ty

LGFox · 2020-06-23T23:28:05Z

TapGestureRecognizer doesn't work on iOS 13.5.1 again. And I publish this app to production. :-(
Updating VS to the latest 8.6.5 (build 23) fixes this issue.

gcadmes · 2020-06-25T15:10:10Z

I'm not having any issues with TapGesture's on iOS 13.5.1

andyfmking · 2020-07-07T09:46:34Z

I'm having issues with multiple tap gesture recognizers on a grid on iOS 13.5

I have a recognizer for 1 tap, and a second recognizer for 2 taps, both on the same grid.

Only gesture recognizer with 1 tap fires on iOS while both gesture for 1 tap, and 2 taps fire on Android.

This means iOS fires only the first gesture with least number of taps and ignores all others.

Expected behavior is as on Android.
When tapped once, handler for 1 tap should fire and when tapped twice the handler for 2 taps should fire e.t.c

Tested on XF 4.6 and 4.7 on Visual studio Mac 8.6.5(build 23) and Microsoft Visual Studio 2019 Ver. 16.6.3

I'm using TouchEffect, with panckeview
