IOS13 CNMutableContact Bug
The problem doesn't occur in iOS 13, but in iOS 13.1.
I think this is a problem with the CNContactViewController, not CNMutableContact.
I'm sorry, but I don't know how to avoid it because of Apple's framework.
Send a bug report to Apple.
CNContactViewController discard message Xamarin
ok, after long search, i`ve found a solution.
to make it work i've added to info.plist values described in official xamarin documentation.
https://docs.microsoft.com/en-us/xamarin/ios/app-fundamentals/localization/
and now it works perfectly. but it is not obvious solution
PS: and for the future, Dear commentators, don't answer in such manner: "I created a new project and just open the CNContactViewController, everything works well on my side. I can't reproduce the issue" - It doesn't bring any useful information. better no answer than answer like this.
How to use CNContactViewController just for creating new contacts? (Swift)
You are using this view controller wrong.
You must not push it onto an existing view controller. Instead you instantiate a UINavigationController with the CNContactViewController as its root view controller, and present the navigation controller as a presented view controller. You must then dismiss the presented navigation controller yourself, in your implementation of contactViewController(_:didCompleteWith:)
.
Also watch out for this bug, which makes this view controller largely unusable:
