Бих искал да създам персонализиран WKWebView клас, защото искам да задам персонализиран HTTP хедър. Но получавам тази грешка:
Методът за отмяна със селектор 'loadRequest:' има несъвместим тип '(NSURLRequest) -> WKNavigation?'
import WebKit
class CustomWkWebView: WKWebView {
override func loadRequest(request: NSURLRequest) -> WKNavigation? {
var mutable_request = request.mutableCopy() as! NSMutableURLRequest
mutable_request.setValue("SHOTWORKS_IOS_APPLICATION", forKey: "App-MyParameter")
return super.loadRequest(mutable_request.copy() as! NSURLRequest)
}
}

Методът за писане е същият като моя код.
Написал съм го само по предложение.
Не знам защо не можах да отменя.
Какво трябва да направя?
След заснемането е тази грешка.
