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];
}
