[assertion] Error acquiring assertion: <Error Domain=RBSAssertionErrorDomain Code=3 "Target is not running or required target entitlement is missing" UserInfo={RBSAssertionAttribute=<RBSDomainAttribute| domain:"com.apple.webkit" name:"Background" sourceEnvironment:"(null)">, NSLocalizedFailureReason=Target is not running or required target entitlement is missing}>
How do I set this entitlement? I've been googling with little success. I am assuming I am doing something dumb and forgetting a setting in either the info.plist of my entitlements.plist. I just haven't been able to find it.
TIA.
@Wally McClure Try to create a new entitlement file and name it Entitlements ,check details :https://learn.microsoft.com/en-us/xamarin/ios/deploy-test/provisioning/entitlements?tabs=windows#adding-a-new-entitlementsplist-file .
There already is an Entitlements.plist file in the iOS project.
Consider raising your issue on github : https://github.com/xamarin/Xamarin.Forms/issues .
Thanks. I am back on this today.

That might sound weird, but ensure the WKWebView has a parent view. If it's not - try to create an empty UIView and add WKWebView as a subview.
