[self.webView.configuration.websiteDataStore removeDataOfTypes:[NSSet setWithObject:WKWebsiteDataTypeCookies] modifiedSince:[NSDate distantPast] completionHandler:^{ // Notice that this is not called. NSLog(@"Cleared cookies"); }]; Expected Results: The completion handler is called and cookies are cleared. Actual Results: The completion handler is not called and cookies are not cleared. 1114655 1 shreyasv 2015-08-04 11:09:16 -0700 rdar://22120241 1115040 2 andersca 2015-08-05 10:18:32 -0700 I can't reproduce this, can you please attach a test app that shows the problem? 1115050 3 shreyasv 2015-08-05 10:37:24 -0700 Reproducibility on simulator 0/5 Reproducibility on device 5/5 Or in other words this bug only affects device builds. 1116422 4 shreyasv 2015-08-10 17:55:31 -0700 I can't repro this bug anymore.
