iOS 10 has introduced new method to open a URL, see below:

Swift 3:

let url = URL(string:"http://www.booleanbites.com")! if #available(iOS 10.0, *) {     UIApplication.shared.open(url, options: [:], completionHandler: nil) } else {     // Fallback on earlier versions     UIApplication.shared.openURL(url) } 

Objective C:

NSURL *url = [NSURL URLWithString:@"http://www.booleanbites.com"];  if ([[UIApplication sharedApplication] respondsToSelector:@selector(openURL:options:completionHandler:)]) {     [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:NULL]; }else{     // Fallback on earlier versions     [[UIApplication sharedApplication] openURL:url]; }
