Bug Can't upload to TestFlight (ITMS-90809: Deprecated API Usage - UIWebView)

We are on Unity 2019.4.13, getting this warning when uploading to TestFlight (due to UIWebView).
ITMS-90809: Deprecated API Usage

I am not using Unity Ads in the project. I know that this was related, but we are not using it.

Examining the built .ipa, i can see that UnityFramework framework has a reference to UIWebView:


Also, according to these bug report, i am not sure if our version includes the fix or not (and if not - WHY?!)

PLEASE ADVISE ON WHAT TO DO TO FIX THIS

 

OK found the problem, 2 seconds after posting this - problem is with Bolts.framework (comes with FacebookSDK)

 

So, how did you fix this? Did you edit the code and change UIWebView for WKWebView?

 

@Starbox It's funny but i honestly can't remember. I am pretty sure we upgraded to the latest Facebook SDK and the issue was gone. What version of FB SDK are you using?

 

Hello,
Thanks for replying! I remember that all advertising SDKs were rushed into updates because of this restriction. However I use Unity Ads as of now so I wondered if this was more a general thing because I had been updating about everything I could think of and this error still keeps coming up. I've already scorched a few build version just to probe the uploader and see if I were getting blocked again.
I may have found one culprit file so I'll start a new thread.
