Don't forget to import the necessary framework first.
import SafariServices
//Objective-C
@import SafariServices;
Instantiate a SafariViewController
instance.
let safariVC = SFSafariViewController(URL: URL(string: "your_url")!)
//Objective-C
@import SafariServices;
NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.google.com"]];
SFSafariViewController *sfvc = [[SFSafariViewController alloc] initWithURL:URL];
Optionally you can also tell SafariViewController to enter reading mode if possible once it's done loading.
let safariVC = SFSafariViewController(URL: URL(string: "your_url")!, entersReaderIfAvailable: true)
//Objective-C
NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.google.com"]];
SFSafariViewController *sfvc = [[SFSafariViewController alloc] initWithURL:URL entersReaderIfAvailable:YES];
Present the view controller.
present(safariVC, animated: true, completion: nil)
//Objective-C
[self presentViewController:sfvc animated:YES completion:nil];
