Xcode 6.3 not running iOS 8.4 - update to 6.4 fails
I have upgraded my iOS to 8.4, then I tried to run Xcode 6.3, it asks it can't mount the device since it's running 8.4 version (".. running a version of iOS that is not supported by this version of Xcode.") When I try to upgrade Xcode to 6.4 - update fails every time with error message (try again using purchases). Any suggestions how to solve this? Delete /Applications/Xcode.app . Download Xcode 6.4 from the Apple Developer Download site. Mount the .dmg and extract Xcode.app into /Applications . Marlon Ruiz You don't need to delete /Applications/Xcode.app. Open a terminal. Copy this: xcode
