Change a NSURL's scheme

Question

Is there an easy way to change the scheme of a NSURL? I do realize that NSURL is immutable. My goal is to change the scheme of an URL to \"https\" if t

Answer 1

Swift5

extension URL {
    func settingScheme(_ value: String) -> URL {
    let components = NSURLComponents.init(url: self, resolvingAgainstBaseURL: true)
    components?.scheme = value
    return (components?.url!)!
}

}

Usage

if nil == url.scheme { url = url.settingScheme("file") }
