In iOS, there have been two webviews for a few years now, UIWebView and WKWebView. Historically, Ionic apps have used UIWebView, but no longer. Ionic now uses WKWebview by default when building for iOS. We strongly believe WKWebview is the best option for any app, as it features many improvements over the older, legacy webview (UIWebView). These features include: 1. JIT conversion of JS code down to machine code, which runs much faster 2. Improved rendering performance 3. Less memory consumption 4. Better adherence to web standards 5. Reliable scroll events (important for virtual-list) We wanted to make sure that people could easily switch to WKWebView without many issues, but there are still some things that you’ll need to consider. Update Ionic CLI WKWebView plugin needs latest Ionic CLI in order to work properly. Please make sure that your global CLI is using the latest 3.x release. If not, please upgrade: npm uninstall -g ionic npm install -g ionic Upgrading to...
