To fix it, you can disable the lazy loading of the view:

<pre><code>SFSafariViewController *viewController = [[SFSafariViewController alloc] init...];
(void)viewController.view;
...
[controller presentViewController:viewController animated:YES completion:nil];
</code></pre>

Update

Turns out the old answer didn't work, it just worked since I put breakpoints. If I added a thread sleep seems it worked in XCode9, but that's not the best solution. Anyone have another better solution?

<pre><code>SFSafariViewController *sfcontroller = [[SFSafariViewController alloc] initWithURL:url];
if (@available(iOS 11.0, *)) {
 [NSThread sleepForTimeInterval:0.5f];
}
sfcontroller.delegate = self;
[controller presentViewController:sfcontroller animated:NO completion:nil];
</code></pre>

Old Answer

I have the same issue as genaks and tinkered around with SFViewController.

Seems like this code works for me

<pre><code>SFSafariViewController *sfcontroller = [[SFSafariViewController alloc] initWithURL:url];
if (@available(iOS 11.0, *)) {
 SFSafariViewControllerConfiguration *config = [[SFSafariViewControllerConfiguration alloc] init];
 config.barCollapsingEnabled = NO;
 sfcontroller = [[SFSafariViewController alloc] initWithURL:url configuration: config];
} else {
 // Fallback on earlier versions
}

sfcontroller.delegate = self;

[controller presentViewController:sfcontroller animated:YES completion:nil];
</code></pre>

In ios 11, they introduce SFSafariViewControllerConfiguration, and by default the barCollapsingEnabled is true and it seems the one that causing my blank SafariView. Hope this solves yours too

blocks|key|1610511|text|到目前为止，对我来说唯一起作用的是以以下方式使SafariViewController成为根视图控制器-|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1610512|++++((XYZAppDelegate+*)[UIApplication+sharedApplication].delegate).window.rootViewController+=+self.svc;

The only thing that has worked so far for me is to make the SafariViewController the rootviewcontroller in the following manner - 

<pre><code> ((XYZAppDelegate *)[UIApplication sharedApplication].delegate).window.rootViewController = self.svc;
 [((XYZAppDelegate *)[UIApplication sharedApplication].delegate).window makeKeyAndVisible];
</code></pre>

We had this issue: our URL was <code>https://our-side.com/index.html</code> (an Angular site that would redirect to the <code>/account</code> route). When we removed the <code>index.html</code>, the <code>SFSafariViewController</code> loaded correctly!

I have tried to do it using delay and make view of controller loading.Both are working for me.

Method 1. Using delay.

<pre><code>DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
 let controller = SFSafariViewController(url: url)
 controller.modalPresentationStyle = .overFullScreen
 self.present(controller, animated: true, completion: nil)
 controller.delegate = self
 }
</code></pre>

Method 2. Loading view.

<pre><code> let controller = SFSafariViewController(url: url)
 let _ = controller.view
 controller.modalPresentationStyle = .overFullScreen
 self.present(controller, animated: true, completion: nil)
 controller.delegate = self
</code></pre>

I have a SFSafariViewController opening at the click of a button inside a UIActionSheet. It has been working fine and is still working fine on all the versions of iOS except iOS 11. Is there something they have changed regarding the SFSafariViewController in iOS 11 or in Xcode 9.0 that might have caused this issue?

UPDATE - So it seems like its Xcode 9.0 that is causing this issue. I have tried running it on different iOS versions and all of them seem to be giving this issue. It used to work fine when I ran it using Xcode 8.3.3, something I don't have anymore :(

Here's the code - 

<pre><code>- (void)presentWebView:(NSString *)url {
url = [url stringByReplacingOccurrencesOfString:@" " withString:@"+"];
url = [url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *URL = [NSURL URLWithString:url];

if (URL) {
 if ([SFSafariViewController class] != nil) {
 SFSafariViewController *sfvc = [[SFSafariViewController alloc] initWithURL:URL];
 sfvc.delegate = self;
 [self.tabBarController presentViewController:sfvc animated:YES completion:nil];
 } else {
 if (![[UIApplication sharedApplication] openURL:URL]) {
 NSLog(@"%@%@",@"Failed to open url:",[url description]);
 }
 }
} else {
 // will have a nice alert displaying soon.
}
</code></pre>

}
