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.

Setup Previews for your project

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:

    // this is perfect for non-greyscale source images, and images that have both highlights and shadows that should be preserved
    // white will stay white and black will stay black as the lightness of the image is preserved
