I've opened an iOS project - with Xcode 4.4.1 - that I hadn't opened for 2 months (ie with Xcode 4.3). First, Xcode was crashing constantly right after displaying the project navigator saying something like "Failed to associate working tree".
I tried to fix it by removing xcuserdata files and the project.xcworkspace directory as well.
Now, Xcode opens without crashing but in the scheme view, it is shown as a Mac OS X project whereas both the project and the target are correctly set to a "Latest iOS" base SDK.
How can I fix that without having to recreate a project and copy all my source files?
EDIT: i'm using Git with a GitHub remote.
make a new scheme for ios by clicking on the current scheme then "new scheme"
