    hi everyone~ I`m upgrading my ios app to obtain ios7 compatibility

    but it keeps crashing in start-up with error message “Failed to load AOT module mscorlib in aot-only mode.”

    I`ve already read the solution in unity wiki

    "Problem: Program crashes and debugger reports: “Failed to load AOT module ... in aot-only mode.”

    Possible Causes: Unknown cause. Possibly another bug in the Unity iPhone build pipeline.
    Possible Solution: Delete the app in the device (using Xcode Organizer) then install it again. "

    I tried it but it`s not worked.

    any solutions???

    Sounds like you Xcode project is broken. When building from Unity try to choose replace instead of appending existing Xcode project.

    Yes, Unity 4.2.1 is tested to work with Xcode 5 GM fine (except build&run and some bugus warnings).

    Mantas is our lead iOS dev. I'd fully expect he's tested on his own machine if he says it works.

    Actually I'm very suspicious about your claims, considering the Xcode 5 GM build was only released the other day.
    So personally I do not believe this has gone through proper testing, this is my opinion.

    $Error.png

    So lets look at example screenshot.
    Firstly un-ticking the external Xcode 4 does nothing.

    So with it ticked it produces a error as seen on screen visible in Unity3d editor.
    So is Unity trying to launch Xcode 4 or looking for it?

    - Two things happened here, either you have not tested latest Xcode Build to confirm to community.
    - Second its my machine setup when installing Xcode 5 overiding Xcode 4 - which could be the case also I admit.
    - Under external tools no mention of Xcode 5- so you saying also by default Xcode 5 acts as Xcode 4

    This error (and the tick in Editor) is related to Build&Run function, which is not working with Xcode 5 GM as I mentioned above. Though this error isn't fatal, it just means you need to open project in Xcode and hit Build manually. Yes, I tested it on my machine with various Unity 4.x flavours and it works.

    Typically top 2 reasons why people get error like the one you posted above are:
    a) Broken Xcode project. (Solution is just to rebuild from Unity and replace project from scratch instead of appending)
    b) Broken Unity installation. Solution is reinstalling it by using these precaution steps:
    - unmount all Unity install images in Finder
    - re-mount the latest Unity dmg
    - run the installer
    - open your project with freshly installed Unity and replace your Xcode project when building with it.

    All our projects compile and run just fine with Unity 4.2.1 and Xcode 5 GM.
    As Mantas said, only build and run is not working and there are some warnings.

    I'm curious - can you have both xcode 4 and xcode 5 on your machine and build to the xcode of your choosing?

    Yes, that's is possible. Though Unity will prefer Xcode 5 for opening project and Build&Run won't work for it, but you still can manually open project in any Xcode you want and click build there.

    Yesterday I bought Mountain Lion, installed it, then got Xcode 5. Not only can I not build run, I can't even open XCode 5. It never starts up. Not sure if that's because it can't start up with a Unity 4.2 project from last session or what. Anything I should try? I ALWAYS use Replace, not Append.

    BUMP!

    When will Unity be updated to fix what apple changed in the scripting interface of XCODE 5 so we can get back to automatic build and run?

    For those of you who have this problem you can simply remove XCODE 5 and go get the last build of XCODE 4 from the apple developer site and install it and get back to mostly normal.
