I would like to implement a feature in the prepareInterfaceForExtensionConfiguration function of the AutoFillCredentialProvider extension that returns to the main app. Since the extension prohibits the use of openURL from sharedApplication, can I use the openURL function of NSExtensionContext through UIResponder? Would this violate Apple’s regulations? private func openContainerApp() { let scheme = "momoshare://" let url: URL = URL(string: scheme)! let context = NSExtensionContext() context.open(url, completionHandler: nil) var responder = self as UIResponder? let selectorOpenURL = sel_registerName("openURL:") while (responder != nil) { if responder!.responds(to: selectorOpenURL) { responder!.perform(selectorOpenURL, with: url) break } responder = responder?.next } }
