[Bug] "ITMS-90809: Deprecated API Usage" in Xamarin.Youtube.Player.iOS

[HealsCodes]

After adding the NuGet package for Xamarin.YouTube.Player.iOS to my project and submitting a version to TestFlight I receive the following mail from Apple:

Dear Developer,

We identified one or more issues with a recent delivery for your app, "xxxxxxx" x.x.x (x.x.x.x). Your delivery was successful, but you may wish to correct the following issues in your next delivery:

ITMS-90809: Deprecated API Usage - Apple will stop accepting submissions of apps that use UIWebView APIs starting from December 2020 . See https://developer.apple.com/documentation/uikit/uiwebview for more information.

After you’ve corrected the issues, you can upload a new binary to App Store Connect.

Best regards,

Taking a quick look over the sources it seems that the YouTube component for iOS is still using / referring to the now long deprecated UIWebView instead of using WKWebView.

NuGet version: Xamarin.YouTube.Player.iOS v0.1.6

This issue also seems present in Xamarin.iOS.MaterialComponents.

grep -r "UIWebView" .

Binary file ./iOS/obj/iPhoneSimulator/Debug/mtouch-cache/MaterialComponents.framework/MaterialComponents matches
Binary file ./iOS/bin/iPhone/Release/.../Frameworks/MaterialComponents.framework/MaterialComponents matches
Binary file ./iOS/bin/iPhoneSimulator/Debug/.../Frameworks/MaterialComponents.framework/MaterialComponents matches

@gadeweever which version does this relate to? I'm also using MaterialComponents (72.2.0.1) and don't get a reference:

./packages/Xamarin.iOS.MaterialComponents.72.2.0.1/lib/Xamarin.iOS$ grep -i UIWebView MaterialComponents.dll
./packages/Xamarin.iOS.MaterialComponents.72.2.0.1/lib/Xamarin.iOS$ strings MaterialComponents.dll | grep -c -i UIWebView 
0

Compared to YouTube.Player.iOS (0.1.6):

./packages/Xamarin.YouTube.Player.iOS.0.1.6/lib/XamariniOS10$ grep UIWebView YouTube.Player.iOS.dll
Binary file YouTube.Player.iOS.dll matches
./packages/Xamarin.YouTube.Player.iOS.0.1.6/lib/XamariniOS10$ strings YouTube.Player.iOS.dll | grep -c UIWebView
117

@Shirk This is on 72.2.0.1. Does the grep change if you also run it on your build output folder?

EDIT: According to this: #745 the pre-release package for MaterialComponents should not have this reference. Consider my addition off-topic.

Any solution for this I am facing same issue

No, none - ended up writing a wrapper around YouTube's iframe API that exposes the javascript interface as a native class.
