WKWebView in Interface Builder

Question

It seems that the IB object templates in XCode 6 beta are still creating old-style objects (UIWebView for iOS and WebView for OSX). Hopefully Apple will update them for the modern WebKit, but until then, what is the best way to create WKWebViews in Interface Builder? Should I create a basic view (UIView or NSView) and assign its type to WKWebView? Most of the examples I find online add it to a container view programmatically; is that better for some reason?

Answer 1

You are correct - it doesn't seem to work. If you look in the headers, you'll see:

- (instancetype)initWithCoder:(NSCoder *)coder NS_UNAVAILABLE; 

which implies that you can't instantiate one from a nib.

You'll have to do it by hand in viewDidLoad or loadView.

Answer 2

As pointed out by some, as of Xcode 6.4, WKWebView is still not available on Interface Builder. However, it is very easy to add them via code.

I'm just using this in my ViewController. Skipping Interface builder

import UIKit import WebKit  class ViewController: UIViewController {      private var webView: WKWebView?      override func loadView() {         webView = WKWebView()          //If you want to implement the delegate         //webView?.navigationDelegate = self          view = webView     }      override func viewDidLoad() {         super.viewDidLoad()          if let url = URL(string: "https://google.com") {             let req = URLRequest(url: url)             webView?.load(req)         }     } }
