Get url schema programmatically in Swift 3.0

func getURLSchema() -> String?{

    guard let schemas = Bundle.main.object(forInfoDictionaryKey: "CFBundleURLTypes") as? [[String:Any]],
        let schema = schemas.first,
        let urlschema = schema["CFBundleURLName"] as? String
        else {return nil}

return urlschema 

}

This does not get the url scheme, it gets the url identifier (often called the url name).

Here is some simple code to get the scheme:

    func getURLSchema() -> String{

        guard let schemas = Bundle.main.object(forInfoDictionaryKey: "CFBundleURLTypes") as? [[String:Any]],
            let schema = schemas.first,
            let urlschemas = schema["CFBundleURLSchemes"] as? [String]
        else {return "nil"}

        guard let urlschema = urlschemas.first
        else {return "nil"}

        return urlschema

    }

thanks
