Use WKWebView instead of UIWebView #321
Description
It would be nice if there were a way to use WKWebView instead of UIWebView when using the <WebView> component, as WKWebView has substantial performance benefits.

It also comes with problems. Would like to differentiate between the 2 as separate components.
LinusU commentedon Mar 27, 2015
@drkibitz What kinds of problem? The only thing I can think of is that it requires iOS 8. Maybe we can choose
UIWebViewwhen on iOS 7 and lower, otherwise useWKWebKit.gabro commentedon Mar 27, 2015
WKWebViewis known to be "broken" or at least unfinished. Here's a relevant thread about why (for instance) Google Chrome for iOS still usesUIWebView: https://code.google.com/p/chromium/issues/detail?id=423444A relevant fragment of the discussion:

We should have WebViewIOS and WKWebViewIOS instead of a generic WebView component. Anyone up for the renaming and providing both implementations?
chandlervdw commentedon Mar 31, 2015
While still buggy, it looks like Telerik has implemented a
WKWebViewplugin for Cordova that gracefully degrades toUIWebViewin <= iOS 7. I agree with @vjeux that we could go ahead and split the components, setting the stage for a workingWKWebView.jaygarcia commentedon Mar 31, 2015
+1 on @vjeux's suggestion.
sophiebits commentedon Mar 31, 2015
Why do we need both?
vjeux commentedon Mar 31, 2015
@spicyj we should be able to expose all the platform features and let the developer pick the one that makes sense for their use case.
sophiebits commentedon Mar 31, 2015
I agree in principle but my understanding is that UIWebView is preferable only if you need a synchronous API (or need to do low-level configuration), neither of which are super compelling reasons from the JS side. I'm okay either way I guess but the
UIWebView/WKWebViewvsWebViewIOS/WKWebViewIOSsuggested naming is odd to me.joewood commentedon Mar 31, 2015
Isn't there still an issue with WKWebView in that it cannot load from a local resource, it has to load over http? Telerik included a mini-http server in the Cordova plugin to workaround this issue, as far as I remember. Just mentioning, as it may not be as simple as a drop-in replacement.

+1 I use Semantic-ui to build my mobile app on iOS , and it kind of slow , maybe the WKWebView will speed it up

Does anyone happen to know if the JIT is enabled in JSContext on desktop?

@hramos any word on if there are going to be instructions on building on iOS from source anytime soon? I would love to poke around on this and other issues, but as I believe we discussed before, the only instructions to build from source are for Android and they are here https://facebook.github.io/react-native/docs/building-from-source.html. Am I missing something? Are there any guides for building from source for iOS?
amloelxer commentedon Jun 19, 2018
Also/ or if someone could explain it to me, I would be happy to make a PR to the docs

I opened this issue over 3 years ago. The lack of action on it has once again blocked a major feature.
smathson commentedon Jul 10, 2018
@ckknight If lack of action is blocking a major feature for you, consider using https://github.com/CRAlpha/react-native-wkwebview. We are using it in production with no problems.

👋 related to this whole
WebViewtopic, just wanted to let you know that "something is moving": within the core we decided to try an planning an "extraction" of this component into its own separate repo for easier maintenance.You can follow along and give feedback here: react-native-community/discussions-and-proposals#3
jamonholmgren commentedon Sep 10, 2018
Because https://github.com/react-native-community/react-native-webview uses WKWebView by default, I'm not planning to migrate this issue over there. This issue can probably be closed.
kelset commentedon Sep 10, 2018
Sounds good to me - closing
luisnaranjo733 commentedon Sep 10, 2018
Should we consider WebView to be officially deprecated from RN and migrated to react-native-community?
kelset commentedon Sep 10, 2018
Basically, yes. It will be properly announced when 0.57.0 is released but yeah, that's what will happen.
