I’ve been trying to make an iOS distribution build for a client to send to him via TestFlight, but when I upload the build to App Store Connect, we get an email about how the app uses the UIWebView API and that we should be using WKWebView. The thing is, neither he nor myself have any idea what could be using UIWebView. I’ve read online that Unity Ads and Unity IAP can use it, but we’re not using either of those.
I did a search through the Xcode project files using the command “grep -r “UIWebView” .” in terminal, and it shows that UIWebView is being referenced in some capacity in libiphone-lib.a in the Xcode project folder, but I have no idea where to go from that, as I can’t directly open that file. I understand that it holds Unity’s libraries in it, and I’m wondering if maybe the reason for this issue is because of the Unity version I’m using. Since most of the game is written in JavaScript, I’m having to work in Unity 5.5.3p1 (My client is pretty adamant about sticking to that right now). Since UIWebView was an accepted API back when Unity 5 was prominent, could the issue be with the Unity version I’m using? Or could it be something else altogether? I’ve searched all over the place and can’t find a definitive answer, so any help would be invaluable, thanks!
You are correct that this issue is caused by your Unity version being out of date. Unity has since removed references to UIWebView in later versions. “libiphone-lib.a” contains a portion of the iOS support code, and it is not possible to patch static library directly.
Darn, that’s what I was afraid of. Thank you for the info though!
