Use if let to parse the optional value:

if let value = result {
    print(value)
}

webView.evaluateJavaScript("(function() { return 'this'; })();", completionHandler: { result in //Handle your variable if let value = result { print(value) } }) I get error, Initializer for conditional binding must have optional type – user3173952 Jun 19 '17 at 16:36
