WKWebView was first introduced on iOS 8. With Apple finally release a deadline for all apps to migrate away from UIWebView, this series and this post is here to help you explore the features of WKWebView. In this blog post you will create a simple web browser with some basic features such as displaying content, back and forward.
One of the most interesting things coming out with Xcode 11 is SwiftUI's PreviewProvider, which provides a way to preview the UI during development instantly on multiple devices, multiple settings at the same time.
To preview UIViewController and UIView, you need to download previewing code from NSHipster
Since we are making this browser with a navigation bar, our main UIViewController needs to be embedded inside a UINavigationController. Therefore the previewing code would be like this:
