A seriously frustrating and naturally time-consuming issue paralyzed me today.
Apple recently released the iOS 5.1.1 update to its mobile devices. Sounds minor and it probably was. But 5.1.1 also signaled the end of life for using OS X 10.6 Snow Leopard for developing for newer OS versions. Snow Leopard supports devices with iOS up to 5.1. Yup, not 5.1.1. Just 5.1. Not much of a heads up but well – time to move on to Lion. So I do.
Today came another surprise. The most current release version of Xcode – 4.3.2 – did not appear to enjoy my iPhone and its iOS 5.1.1. Organizer saw the device, added it to the provisioning portal team (removed, added, removed, added, etc.) and added and removed the provisioning profile for the app. Still, Xcode would fail to recognize the device and stick with the blank 'iOS Device' in the execution scheme.
Finally, I stumbled across this post in Apple's Developer Forum:
"The latest Xcode for Snow Leopard is 4.2 and that appears to be the highest it will go. 10.6.8 is required for iOS support.
The latest Xcode for Lion as of 5.7.2012 is 4.3.2, which requires 10.7.3 and is needed to work with iOS devices at iOS v5.1.x – v4.3.2 is an application that will be installed to your /Applications folder. Xcode 4.3.2 comes with 5.1 SDK and supports iOS 5.1.1…connect your device and let Xcode download 5.1.1 symbols."
The part I seemed to be missing seemed to be the "let Xcode download 5.1.1 symbols".
Further digging on StackOverflow had the answer: essentially power cycle your iOS device and THEN reconnect it to your Mac. Let iTunes start up and finish its scan of the device. Then close it and start Xcode. I ended up also restarting my machine. I then created a NEW project and had it detect the iOS 5.1.1 device successfully.
Still, I am unable to get projects that were created before 5.1.1 came out to detect the device. Luckily nothing is major there but this is clearly a rather grim bug in Xcode.
