On Xamarin Forms 18.104.22.168, the ListView is broken on iOS 10 beta's. Setting ListViewCachingStrategy to RecycleElement freezes the app. No errors occur, app just freezes. Setting ListViewCachingStrategy to RetainElement fixes my simple ListViews.
However setting ListViewCachingStrategy to RetainElement on a complex ListView that has many DataTemplateSelector's, the app freezes once again.
Xamarin Forms 22.214.171.124 works on iOS 10 beta without any issues.
Xamarin Forms 126.96.36.199 on iOS 9 works without any issue.
Confirmed on physical iOS 10 beta 8 devices, iPhone 6S and iPad Air.
Attached is a very simple project show that won't work on iOS 10 beta, but changing ListViewCachingStrategy to RetainElement works.
I believe this bug might be similar to https://bugzilla.xamarin.com/show_bug.cgi?id=43907

I'm experiencing this very freezing problem for a while now (actually since the release of Xamarin.Forms 188.8.131.52) and since iOS 10 is no more beta, a fix would be awesome!
Same issue here.
Would like to submit an update before the big release of iOS10;
iOS 10 just got released and I had to find out, that nothing is fixed. Not even in the latest XForms pre-release.
Any update on this issue?
This is also an issue when ListViewCachingStrategy is RetainElement, but a ViewCell has ContextActions.
@Michael is correct we also see this behaviour with RetainElement lists that have ContextActions :/
There seems to be Xamarin.Forms 184.108.40.206 out now on nuget. For me it's working again with ContextActions in a custom view cell. Hope Apple will approve the new version quickly...
Upgraded my project from Xamarin.Forms 220.127.116.11 to 18.104.22.168 and I don't experience the freezing bug anymore. Thanks.
Should be fixed in 2.3.2. Thank you!
