ios 5.1 with xcode 4.2 for iOS development
I updated my iPhone to iOS 5.1.
My operating system is Snow Leopard.
Now I need the sdk 5.1 to develop, with xcode 4.2.
Where can I download it?
Any suggest?
Solution:
Downgrade to ios5.0 or update to Lion
You can’t.
You need to update to Mac OS 10.7 Lion in order to get the latest version of Xcode with the 5.1 SDK.
The last installable version of Xcode on Snow Leopard will be 4.2. Apple really wants developers to keep up to date on everything, whether MacOS or iOS.
