Hello everyone,I have a query with regards to Game Center authentication capabilities. While taking this method into consideration I arrived at an edge case for which I would request some additional information or guidance. In the following event: 1.An user boots the app on an iOS device and authenticates with a Game Center account 2.Then resets the device to erase hishers information of it (maybe to sell it) 3.Picks up another device to play the same app on, but this time he does not sign in with a Game Center account 4.The user plays for a while and makes some progress 5.Then decides to sign back into the previously used Game Center account. At this point a conflict would arise between the existing progress information between the Game Center account and the local progress (achieved without the Game Center account). Given the available documentation, would it pose a concern to show user a warning dialog informing that due to the Game Center sign-in, the user can now either overwrite his current pro

I cannot sign out of my iCloud account via system prefs. Also, I am unable to select the Contacts checkbox nor the Notes check box in my iCloud account is system prefs. This is the cause for iMessage not displaying names and only numbers I'm guessing. Anyone found a solution to get contacts working?I additionally cannot enable iCloud Drive, Mail or Back to My Mac. I am able to check the checkbox, but it is immediately removed.

This is a follow up to the thread, Troubleshooting the launch of local user XPC Launch Agent, in the original (and now archived) Dev Forums.Based on further tests, I assume there must be some configuration that I'm not setting up correctly, as opposed to the code.I started from scratch again with a fresh Xcode Project. This time, I based the code mostly on the example code posted by Apple Engineer eskimo1 in this thread (which uses an privileged Launch Daemon) with a modification or two based on the code posted by Apple Engineer dsorresso in this thread. As I assume that their code can be expected to work (i.e.- to help rule out a coding error on my part). Except that I modified the code so that it works with/as an XPC Service Launch Agent without the privileged aspect and which resides inside of the user's home directory.The following was all done on OS X 10.10.3 (14D136) Yosemite and built with Xcode 6.3.2 (6D2105).* I first started off both the command line interface program and the XPC Service Launch Agen

SecKeychainRef ...; SecKeychainStatus status; err = SecKeychainGetStatus(keychain, &status); if(err == noErr) { if((err = SecKeychainUnlock(keychain, keychainPassword.size(), pass, pass != 0))) { throw unable to unlock keychain; } } else if(err == errSecNoSuchKeychain) { const char* pass = keychainPassword.empty() ? 0 : keychainPassword.c_str(); if((err = SecKeychainCreate(keychainPath.c_str(), keychainPassword.size(), pass, pass == 0, 0, &keychain))) { throw unable to create keychain; } k.reset(keychain); }I use a code like this to Unlock the keychain and create it if not exists, then I have a test case were several servers use the same keychain, and they could run this code concurrently if separate processes.In such case I see that SecKeychainGetStatus some times fails with error: 100022 description: UNIX[Invalid argument]. Could this be related to concurrent calls to SecKeychainUnlock/SecKeychainCreate on the same keychain?Any recomendations on how to handle this execenario in wic

Hi,My iPad app was approved yesterday morning (about 30 hours ago) and shows as Ready for Sale in iTunes Connect, yet it is still not available in the app store. I know this process can sometimes take a few hours but I don't think it should take this long.Should I keep waiting or is there something else I can do?

Can anyone suggest what I need to do to get the new Swift Standard Library to run with Xcode 7 beta on OS 10.10.3 (i.e. _not_ 10.11 beta)?I consistently get Unable to find a suitable target device as soon as I go to a playground page with executable code in it. Prompted by a Stackoverflow suggestion for a previous version of Xcode, I have tried creating an iOS 9 simulator device, but that has not solved the problem. Unlike a full-fledged project, a playground does not seem to have any way of attaching it to a device, real or simulated.

Two parts to session:Transitioning to IPv6-only networksReducing Delays in NetworkingTransitioning to IPv6-only networksMore mobile carriers are moving to IPv6 networksIn Ye Olde Days, cellular data networks used IPv4. As IPv4 addresses ran out, NAT was introduced to make IPs go further.To fix the long-term problem, mobile carriers are now moving to IPv6. But they're also having to support IPv4 with NAT.The carriers want to drop IPv4 with NAT, so they're deploying DNS64/NAT64 to handle translation between IPv4 and IPv6 networks.DNS64 synthesizes an IPv6 address for an IPv4-only serverNAT64 performs IPv6 to IPv4 address translationApp Store apps need to be IPv6 ready - It will be an app submission requirement later in 2015.Enabling IPv6 test network from a Mac1.

Hello Everyone,Like many others i installed Watch OS 2 on my Apple Watch a few days after WWDC. Since then the experience of using the Watch was a complete nightmare. I have had many problems including contacts not syncing via my iPhone, not receiving notifications, home screen freezing , the watch running warm against my skin, and worst of all poor battery life. My watch only seem to last 4 hours on a single charge ever since the beta was installed. Even though Apple has not documented a way to downgrade. I decided to try to figure out a solution on my own. I tried many things like downgrading my iPhone to iOS 8.3 to see if I could force a downgrade, nothing happened. I even tried resetting the watch back to factory settings and setting up as a new watch, still nothing happened. The Apple watch app even showed me an alert saying that my iOS was out of date to use the watch. As a final resort i reupgraded my iPhone to iOS 9 just to get the Watch paired up to use, until the next beta or until somebody figured

There is an app that I want to get, but it is not in the iTunes App Store. Is there a way I can request to get it into the App Store?
