How to check validity of URL in Swift?

Question

Trying to make an app launch the default browser to a URL, but only if the URL entered is valid, otherwise it displays a message saying the URL is invalid.

How would

Answer 1

Try this:

func isValid(urlString: String) -> Bool
{
    if let urlComponents = URLComponents.init(string: urlString), urlComponents.host != nil, urlComponents.url != nil
    {
        return true
    }
    return false
}

This simply checks for valid URL components and if the host and url components are not nil. Also, you can just add this to an extensions file
