I’m working on updating an iPhone application with a minor change in its default configuration. It’s been awhile since I’ve built it last, though, and so I’ve upgraded Xcode to 4.2 and included iOS 5 support in the latest builds.
When I go to test on the device, I get the following assertion error:
2011-11-02 20:57:18.869 RoseBandwidth[903:707] Tried to add item, got result: -25243
2011-11-02 20:57:18.870 RoseBandwidth[903:707] *** Assertion failure in -[KeychainItemWrapper writeToKeychain], /Users/tim/code/RoseBandwidth/Classes/KeychainItemWrapper.m:312
2011-11-02 20:57:18.872 RoseBandwidth[903:707] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Couldn't add the Keychain Item.'
I’m using the implementation of the KeychainItemWrapper class from Apple’s GenericKeychain project. It’s worth noting that this error only shows up on the device, not in the Simulator (and I’m aware of the access group restriction differences between platforms, but usually I thought that caused problems on the Simulator, not actual hardware).
Why would I be getting this error back? I’ve touched nothing relevant to the keychain-related parts of the app; it stores and retrieves data exactly like it used to.
Okay, I couldn’t quite get your project to build, but from How to share keychain data between iOS applications I think you might want to check your entitlements file. At least in the github project you didn’t have anything specified in the Keychain Access Groups.
