You should create the webView in the main thread – (void)createWebView{ if (![NSThread isMainThread]) { dispatch_async(dispatch_get_main_queue(), ^{ [self createWebView]; }); return; } self.webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)]; //Rest of my code }
Right now, WKWebView instances will ignore any of the default networking storages (NSURLCache, NSHTTPCookieStorage, NSCredentialStorage) and also the standard networking classes you can use to customize the network requests (NSURLProtocol, etc.). So the cookies of the WKWebView instance are not stored in the standard Cookie storage of your App, and so NSURLSession/NSURLConnection which only uses … Read more
Have you tried setting it like this? let config = WKWebViewConfiguration() config.setValue(true, forKey: “allowUniversalAccessFromFileURLs”)
I’ve successfully used the SPI -[WKWebView _printOperationWithPrintInfo:] passing the usual [NSPrintInfo sharedPrintInfo]. Note that you CAN’T use -runOperation on the returned NSPrintOperation. You must use -runOperationModalForWindow:…. which is quite similar. The problem resides in the WebKit internals that expects a running runloop and a preview to be made internally to know the number of pages. … Read more
To stop ‘white flash’ on your dark background, do this webView.opaque = false This doesn’t really solve background colour issue, but at least it stops ‘white flash’ you are experiencing. Apparently there seem to be no way to change background colour of WKWebView before loading HTML on it. Swift 4 webView.isOpaque = false
These and other issues are all fixed as of iOS 13.
This is a simplified version of what I have used to load local files in a project of mine (iOS 10, Swift 3). I have just updated my code (7.5.2017) after testing it out again on iOS 10.3.1 and iPhone 7+ as requested by Raghuram and Fox5150 in the comments. I just created a completely … Read more

Answer (Big thanks to @paulvs ) To check if your WKWebView has loaded easily implement the following method: import WebKit import UIKit class ViewController: UIViewController, WKNavigationDelegate { let webView = WKWebView() func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) { print(“loaded”) } override func viewDidLoad() { super.viewDidLoad() let url = URL(string: “https://www.yourwebsite.com/”) ! let request = … Read more
Got this working by using the same WKProcessPool for all the webviews. First create a process pool once somewhere: processPool = [[WKProcessPool alloc] init]; Then use it when creating WKWebviews. The pool must be set in the init method, not afterwards. WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init]; config.processPool = processPool; webview = [[WKWebView alloc] initWithFrame:frame … Read more
