Fix provided in #7882 results in issues on iOS Apps running on Simulators and on Devices #8255
Comments
Thanks to @mauroa. With his help, I could remove this blocker temporarily by installing older iOS Simulators on XCode 11.4. Xamarin.iOS team - the navigation / event issues is also faced in my app for a two level navigation scenario in the masterdetail page setup - where navigating from detail page to the subdetail page is not working. The subdetail page link is not even firing any event. This issue exist even in iOS 13.2.2, 13.0. So, it is likely that a bug on these scenarios was already out there but got amplified in XCode 11.4. |
Actually, I misread. I'm unsure if this is |
I wonder if iOS 13.4 actually changed behavior and Xamarin.Forms needs to react accordingly but on the what I am not sure |
This is the key which leads me to believe that
This is a behavioral change if you use an older simulator you are using an older iOS like 13.2 so this is not Xamarin.iOS fault |
@dalexsoto - I disagree with your assumption there. I have distinct behavior of the app responding to my navigation bar buttons differently in iOS 13.4 and 13.2. More than happy to do screen share. The same code base works just fine on Android. You really may want to see it to for further analysis on your end. |
Please read the comments from #7882 that pretty much points to events not getting fired at for different situations when clicking various types of Xamarin Form ViewControls. |
We have a repro and believe we understand the bug. A fix is in work. |
