title: Change from UIWebView to WKWebView
body: <p><strong>I'm trying to change my <code>UIWebView</code> to <code>WKWebView</code></strong>.</p>
  
  <p>My <code>WebPageViewController</code> just looks this simple on Storyboards:
  <img src="https://i.stack.imgur.com/CLZn6.png" alt="enter image description here"></p>
  
  <p>I'd like to implement the Reading View and back buttons and estimated progress, but I'm not sure if I'm even getting this first step right.</p>
  
  <p>If the first step is right though, and I'm wanting to set up the configuration, am I adding something like this to my code?:
      <code>WKWebViewConfiguration *theConfiguration = [[WKWebViewConfiguration alloc] init];</code></p>
  
  <p>And would I need to add a <code>@property (strong, nonatomic) WKWebViewConfiguration *configuration;</code> to get it all working?</p>
  
  <p>Here's my code changes so far if needed:</p>
  
  <p><strong>WebPageViewController.m UIWebView</strong></p>
  
  <pre><code>@property (strong, nonatomic) IBOutlet UIWebView *webView;
  
  -(void)viewWillAppear:(BOOL)animated {
      NSURL *url = [NSURL URLWithString:stringWeb];
  
      [self.webView loadRequest:[NSURLRequest requestWithURL:url]];
  }
  </code></pre>
  
  <p><strong>WebViewController.m WKWebView</strong></p>
  
  <pre><code>@property (strong, nonatomic) IBOutlet WKWebView *webView;
  
  -(void)viewWillAppear:(BOOL)animated {
  NSURL *url = [NSURL URLWithString:stringWeb];
  
  [self.webView loadRequest:[NSURLRequest requestWithURL:url]];
  }
  </code></pre>
