Possible regression with a header in a ListView with Xamarin.Forms 184.108.40.20671 (and higher) on Iphone 4 IOS 7.1. We have the same problem with the latest version of Xamarin.Forms (220.127.116.1190). However, we no longer can reproduce the problem with an iPhone 5C IOS 8.3 and we had no problem with Xamarin.Forms 18.104.22.16847 on Iphone 4 IOS 7.1.
When I am on a page containing a ListView with a header and I do a PopAsync via NavigationPage my app crashes.
**Steps to Reproduce:**
1. Run the attached sample on an iPhone 4 iOS 7.1 device/simulator
2. Press the button to navigate forward.
3. Press back
**Build Date & Platform:**
Reproduce it on Xamarin.Forms 22.214.171.12417-pre5 on iOS 6 device (iPod) under iOS 6.1.5
I found description with log on Xamarin forum : https://forums.xamarin.com/discussion/59887/crash-when-going-back-to-a-view-on-iphone-4
remove listview Header fix this crash.
Still crashing as of 126.96.36.19929. If I set the the ListView Header to null in the OnDisappearing event of the page, it no longer crashes and I can use the ListView Header on iOS 7. This is not ideal because I have to manage this and recreate the header OnAppearing.
I tested this in XF 188.8.131.52-pre2 / iOS 10 / iPhone 6. For me, the issue does not exist.
