Excuse my ignorance, but I’ve not done an Xcode upgrade before. I thought I’d simply go to apple, download the .dmg file, double click it, and voila! However, after doing this (the .dmg file is a 1.56GB file), if I run Xcode by clicking the icon at the bottom of the screen, when it loads, if I check the version, it still says 4.3.2. So obviously, I haven’t done something needing to be done.
Also, I’m not duplicating the message anymore so I can’t give an exact quote, but when launching Xcode I got a message that it didn’t recognize the device. I presume this is my iPad, which was provisioned as a development device before I upgraded the iOS to version 6 on it.
Perhaps my question can be answered by simply pointing me to an appropriate document. The websites I’m finding all seem to be about problems after upgrading. I haven’t got that far yet, I don’t think.
If you have downloaded the DMG file, you will need to double click on it so it can mount the image file .In that dmg file there is the xcode file you need and copy that into your applications folder. If you already have a xcode app in there it will override it.
Otherwise if you are not a developer, it is indeed easier to just download it from the app store. Good Luck:-)
