NSSet *dataTypes = [NSSet setWithArray:@[WKWebsiteDataTypeDiskCache,
                                         WKWebsiteDataTypeMemoryCache,
                                         ]];
[[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:dataTypes
                                           modifiedSince:[NSDate dateWithTimeIntervalSince1970:0]
