[FIXED, RELEASE IN V3.0.0] UIWebView iOS Deprecated API Usage Warning ITMS-90809

[Johan-dutoit]

THIS HAS A MERGED FIX - IT WILL RELEASE IN V3.0.0 HERE*

See react-native-webview/react-native-webview#819

I have not yet submitted a new version of the app, but I searched my node_modules and found that this module referenced UIWebView too.

See: https://github.com/react-native-community/react-native-device-info/blob/8efe2efaba6b01a1d48a0238ff91ab8e9d39f4ab/ios/RNDeviceInfo/RNDeviceInfo.m#L118

I could submit a PR for that but then the Android part would also have to be asynchronous (as WKWebView evaluateJavascript is asynchronous). Is that fine @mikehardy?

[mikehardy]

Dang. This may be the time to finally do the big promise-based breaking change. I've got a bit of time this morning maybe I can crank it out. I don't want to just trickle in async changes when everything needs to go async really.

@Johan-dutoit / @radko93 I read through the linked discussion and did not see any statement on when it would become a hard requirement and fail an app store build vs just a warning. Could one of you guys dig and find when this becomes a hard fail? That will help prioritize

[mikehardy]

@radko93 I would definitely appreciate a PR that implemented the required API change - while I may not ingest it as is (because I want to do all the async changes at once) it would be really really helpful to me to have the ObjC portion of the PR from someone who knew what they were doing :-). If you converted it to a Promise at the same time I could probably just include the commit raw into the promise-ify commit stream anyway, to maintain attribution

[Johan-dutoit]

@mikehardy can we assume it's going to be with iOS 13? i.e. anything that targets iOS 13, which would mean less than 2 months away.

The documentation currently states the following, although we will have to check back once 13 is released.

Other than that, I've been unable to find a concrete timeline.

[mikehardy]

No one seems to know concretely in the react-native-community Discord chats or the webview component or stackoverflow. I think that's a reasonable guess though, thank you. If anyone posted the recommended ObjC changes that would help me 🙏 and we could get something up quickly to start working through project-specific testing etc

[mikehardy]

This is merged and will release with v3
