    Just updated my device with iOS 6.0, and now XCode 4.5 doesn't see my device anymore.

    In the run window, it only says "iOS Device".
    In Organizer, it says "This device is not currently connected."

    I have pull out the cord and re-connect it, wait until iTunes does it sync thing, and then wait
    patiently because it's so darn slow now...and then....

    "XCode quit unexpectedly"

    Restart XCode again, and its back to "iOS Device". This is plain stupid.
    Do they have a bunch of monkeys at Apple testing this before they release it?

    No, I change nothing. XCode 4.5 is extremely slow in finding my device now.
    This is due to iOS 6.0 being installed. My device is a iPod Touch 4.

    I don't have to re-connect my device as I discovered.

    I have to wait up to 3-5 minutes now for XCode 4.5 to find my device. Apparently, XCode has
    lost its brain.

    Then, when I try to compile and run my app on the device, I have to wait another 3-5 minutes
    for XCode 4.5 to figure it out again.

    This is ridiculous. I can't work like this. I rebooted everything. Still slow.

    Will be going back to iOS 5.1.1 after I figure out how to do it.

    Make sure some other process is not interfering. For example I always have had issues when I do not pay attention and realize that iTunes is doing a backup of my iPhone. Then I have a delay of xcode not seeing my device.

    Thanks, but I don't think iTunes and XCode are fighting over my device at the same time.
    Nor do I think the problem is related to the latest version of iTunes or XCode.
    In fact they both struggle with the same problem.

    iTunes is slow to sync/backup my device everytime it runs.

    XCode is slow to recognize my device as a debugging device. It has to look for
    my provisioning profiles on the device.

    So, it must be iOS 6.0 running on my iPod Touch 4. This is something Apple must fix.

    I was able to get iOS 5.1.1 running again, so I'm back in business.

    If I had to guess what the problem was, I would say hardware is to blame.
    The iPod Touch 4 was not designed to handle iOS 6.0. It's slow and slugglish.

    Specs for the iPod Touch 5 has changed:
    CPU: A4 -> A5
    RAM: 256MB -> 512MB
    HD: 8GB -> 32GB

    It's expecting twice the memory and twice the space, and just turns into a power hog.
    I wouldn't be surprised if it eats away at your battery life twice as fast too.

    So, I wouldn't recommend anyone to upgrade to iOS 6.0 if they have a iPod Touch 4.
    If you do, you better have a backup plan. Save your IPSW file for iOS 5.1.1, otherwise
    iTunes will delete your old IPSW files without your permission if you try to upgrade.

    Similar problem on iPhone4s

    I have a similar problem on my iPhone4S and iPad 3rd gen, it takes a long time to deploy the app on the device, while it is fast on the simulator
