Sample Project


   Possible regression with a header in a ListView with Xamarin.Forms (and higher) on Iphone 4 IOS 7.1. We have the same problem with the latest version of Xamarin.Forms ( However, we no longer can reproduce the problem with an iPhone 5C IOS 8.3 and we had no problem with Xamarin.Forms 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

**Actual Results:**

   App crashes. 

**Expected Results:**

   No crash. 

**Build Date & Platform:**

   XF 2.0

Still crashing as of  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 / iOS 10 / iPhone 6. For me, the issue does not exist.
