    Great! Nice Job!

  • Shashank

    Really cool to see you guys working on performance. That’s always been the biggest issue especially on older devices.

  • Kévin

    Working really well thanks ! PouchDB doesn’t work with it by default though so I’ve switched to is a nice workaround.

    • Young Park

      Hi, I’m also using PouchDB but I’m getting this error.. after installing wkwebview. any help?
      WebSQL threw an error Error: Error code 14: unable to open database file

      • yesimahuman

        Web SQL is not available in WKWebView as it was deprecated. Are you seeing this issue with Ionic 2 Storage or something else? If it’s Storage, we’re close to releasing a tweak of the Storage engine to not use WebSQL anymore

        • Young Park

          Have you guys ever tested with PouchDB? Just wondering because i tried with different adapters
          but seems non works.

          • danbucholtz

            We did not test PouchDB. We tested local storage using the Ionic API, WebSQL/sqllite, IndexedDB, file access, and a few other use cases. WebSql is disabled in WKWebView, and IndexedDB does not work in iOS 9. My guess is that is why PouchDB is failing. Can you tell PouchDB to use sqllite? Nolan Lawson (PouchDB maintainer) makes a sqllite Cordova plugin that we have tested with (

            Have you test IndexedDB? Still not working? Maybe you can test FruitDOWN adapter from pouchdb

          • Young Park

            I tested both websql and indexedDB (using Fruitdown).
            none works, since wkwebview do not support both.

            PouchDB author suggested to use cordova-sqlite adapter, but not stable at this point.

          • Kévin

            It works for me very well like I said with

            I’m on [email protected]

            here is how I import PouchDB

            var PouchDB = require(“pouchdb”);

            (window).PouchDB = PouchDB;

      • interferences-studio

        I go the issue when using the wkwebview : WebSQL threw an error : SecurityError: DOM Exception 18. With the previous web view, it was working properly
        I am using PouchDB 5.4.5 and cordova-plugin-sqlite2. Any idea ?

  • jokeyrhyme

    I noticed that “Plugin Repository” links to the Ionic fork from the original Apache copy of this plugin.

    Will we see these changes included in the upstream Apache version (which has a nice NPM name)?
    Or will we see the fork published to NPM under a different name?

    • danbucholtz

      We’re working with the Cordova team to get our changes eventually merged in to the main WKWebView plugin repo. We’re actively looking for beta testers so we can resolve any issues before we proceed with that process.


      • Joshua Rubin

        Would love to see this- been struggling with layout and animation glitches (and iOS version dependence) in my Cordova project. It’s pretty critical that the community moves to a supported web view. (And would be happy to beta).

  • Hanz Gan

    Been waiting for this! Keep pushing the limits!

  • ghenry22

    Awesome to see this, if the holes in wkwebview can be plugged so it’s actually usable that is fantastic. Just gave it a try on my project which is currently using ionic2 beta10 and came across one issue you might want to look at or document:

    If you use the cordova-plugin-splashscreen, make sure that the autohidesplasscreen value is set to true in your config.xml as below:

    Otherwise an exception is thrown in the native code that it cannot remove an observer from CDVsplashscreen and your app will hang. You can reproduce by adding the splashscreen plugin with the value set to false on any default project and just watch the native console output in xcode. Does throw anything in the javascript console so if you aren’t running in xcode you will be incredibly frustrated.

  • Guillaume

    What about taking pictures? I’ve had this issue with wkwebview for a while and nothing seems to have been done so far…

  • Ralf Kistner

    The benefits are a little over-stated here.

    1. I’ve found effectively no memory improvements in practice. The memory is simply moved from the main process to an external process used for the web view. In the conference app example, I’d guess that the external process would consume around 140MB of RAM.

    2. The Chrome quote is not relevant to Cordova apps. In Chrome, it now means that when the webview process crashes, only the single tab is affected. In a Cordova app however, the webview process crashing would mean taking down the entire app anyway. It will likely end up with a blank white screen, which could be even worse than crashing.

    That said, I have found that WKWebView fixes a few significant UI glitches that I haven’t been able to work around in UIWebView (especially glitches related to scrolling).

    I also expect the XHR workaround in this fork to make migrating to WKWebView significantly easier.

    • Wei Keat Ho

      Hi @rkistner:disqus , I do agree the memory usage is shifted from the main process to the external process. It’s 3 months since you’ve posted here, Is there a remedy for this? Something to clear the external process memory usage before the blank white screen appears… Ionic state.go has memory leakage in version 1.2.4. Does upgrading the ionic version help?

      • Ralf Kistner

        I’m not actually using this in production yet. Not sure if there are any remedies.

  • Oliver Faderbauer

    How does this copare to Crosswalk? AFAIK Crosswalk wraps the webview and provides additional performance (somehow automagicly). So does this now replace crosswalk, or will they work together?

    Or am i just comparing apples and bananas?

    • Manu Martinez-Almeida

      Crosswalk is a Android only technology. You should expect a similar crosswalk performance in iOS with WKWebView!

      • Oliver Faderbauer

        Well that makes sense, nice 🙂 Thanks for the clarification.

      • Mike Callaghan

        Also, isn’t Crosswalk designed for older Android devices that don’t use Chrome by default? This seems more for modern iOS devices.

      • Easy2Meet

        It does seem like crosswalk also has a wkwebview project targeted at ios. I haven’t tried it, but you should therefore be able to use crosswalk for both ios and android. (is there anyone with the experience to back this up?)

  • Nick Kenens

    God, I love you guys so much.

  • Luís Cunha

    Your commitment not only to ionic but also cordova and performance makes me very happy =)

  • t_specht

    Those are fantastic news! Can’t wait to implement this in my application!

  • Nicolás Broggi

    Does this work with Ionic View? I upload my app but it returns “UIWebView”

    • Tim Lancina

      Not yet! But we’ll probably add it in a future release.

      • Nicolás Broggi

        Ok! Thanks!

  • sandeepperkari

    Hi, I have added WKWebview plugin to my Ionic project yesterday, I see XHR errors, pages not loading, I see the following errors in the console “CDVWKWebViewEngine: XHR intercepted”, “CDVWKWebViewEngine: requested path can not be accessed: file:///var/containers/Bundle/Application/”, Failed to load resource: Origin null is not allowed by Access-Control-Allow-Origin. Can some one help me out?

  • Sagiv Frankel

    worked nicely on the simulator but failed on the device.

    Does this work nicely with crosswalk?

    On another note, when ever I change anything with plugins my app goes haywire.
    Could you guys maybe do a post on the plugin system?
    I recently stumbled upon this – which helps out a lot but I still don’t understand:
    – How do I lock down a specific version? Ionic state seems to only save the package name.
    – why do some plugins get saved in the config.xml? should they be in both the config.xml and the package.json.

    Working with the plugin systems can be a big challenge sometime and more info would help a lot.

  • Easy2Meet

    Did anyone have experience swapping the Telerik wkwebview plugin with this plugin?
    The Telerik plugin (for example) does not support the latest version of Cordova-IOS, so swapping would be awesome for us.

  • Zarko Hristovski

    Heads up for anyone using localForage (and angular-localForage). I had slightly older versions of them libs in place and noticed one blocking issue after manual debugging – $localForage.setItem would not return at all.
    Just for reference, this was observed in an Ionic 1 app.

    Unsure of the reason but make sure you are on the latest version of the libs (1.4.2 and 1.3.1 respectively at this moment). Once updated the problem was gone.

  • Marco

    I used wkwebview in the past. If you use inapprobrowser plugin too, pay attention. We had big issues with it and removed the wkwebview plugin. We used the inappbrowser plugin for paypal, so it was a big issue for us. Dunno if it’s solved yet.

    • Jiří Voseček

      Will try it in a few days.

  • Zarko Hristovski

    Here’s one more general heads-up as something to be aware of in a scenario where you have to move existing users over to an instance running in WKWebView:
    “Persisted data lost when moving to WKWebView”

  • Shion

    Phaser games don’t work inside Ionic with this plugin.

  • Miloslav Skacel

    HttpOnly cookies are not attached to request. Cookie based authentication is thus not working for me in WKWebView, but it is working in UIWebView.

  • Ctibor Laky

    Plugin helped me to get smooth scrolling on some views where it was broken, for example views with infinite-scroll lists.
