[quote='788684022, MobileTen, /thread/756036?answerId=788684022#788684022, /profile/MobileTen'] Then change link from an empty string to a valid URL string to prevent the URL init from returning nil. [/quote] The string starts as nil until the end user supplies one. I'm struggling to prevent fetching until the link is valid. Do you have a suggestion for what to put there for the init that won't blow up for the end user?

Okay, I changed things up a little for testing. Progress: // BrowserViewController.m #import <UIKit/UIKit.h> #import <WebKit/WebKit.h> @interface IABrowser : UIViewController { UIWindow *window; } @property (nonatomic, strong) WKWebView *webView; @end @implementation IABrowser - (void)viewDidLoad { [super viewDidLoad]; #pragma clang diagnostic push #pragma clang diagnostic ignored "-Wdeprecated" window = [[ UIApplication sharedApplication] keyWindow]; #pragma clang diagnostic pop self.webView = [[WKWebView alloc] initWithFrame:self.view.bounds]; [ [ [ window subviews ] objectAtIndex: 0 ] addSubview: self.webView]; // [self.view addSubview:self.webView]; NSLog(@"viewDidLoad"); } - (void)loadURL:(NSString *)urlString { NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:request]; NSLog(@"loadURL"); } @end When I click the button in the UI that should spawn this webView I get the log message that says 'loadURL' but nothing actually appears on screen. I know I'm missing something simple but I truly don't know what it is.
