Dear Apple,The requirement of my application is that can delete cache/cookies in WKWebview. I tried somthing and it working as well in iOS 9 upwards. But there are no way to do it in iOS 8. Please let me know if there is a way to remove cache/cookies in iOS 8 or it can not remove?#Note: I want to remove cookies immediately, ie stay at WKWebview but click url to another site it will delete.Thanks,Phong Tran.
