NSURL Error in XCode 8.2.1

Question

BEGINNER ALERT! Please talk to me like I'm a 5-year-old because I am new to this platform and language. I will be grateful and unoffended.

I have the following code in my Xcode project to open a website in the native browser from a button on the app home page:

@IBAction func faceURL(_ sender: Any) {

    NSURL *spotiURL = [NSURL URLWithString:@"https://www.facebook.com"];



    [[UIApplication sharedApplication] openURL:faceURL options:@{} completionHandler:^(BOOL success) {

        if (success){

            NSLog(@"Opened url");

        }   

    }];

}

On the line:

NSURL *spotiURL = [NSURL URLWithString:@"https://www.facebook.com"];

it's throwing the following error:

Expected "," separator Consecutive statements on a line must be separated by ";"

It recommends putting a

;

between the colon and

@

symbol before the URL. I know some of this is deprecated with the new Xcode and Swift format, but I can't find a straightforward answer for this particular issue. Thank you in advance for your wisdom.

It looks like you're trying to use Objective C code in a Swift method. If your project is written in Swift then this is (probably) the code you need:

@IBAction func faceURL(_ sender: Any) {

    if let facebookURL = URL(string: "https://www.facebook.com")
    {
        UIApplication.shared.openURL(facebookURL) // the open method you were using doesn't exist in Swift
    }
}

I'd suggest you work through a few tutorials to learn the basics of iOS development.
