The \"Debug / View Debugging\" menu is always grayed out for me in Xcode 5 (and 6), even when the target is stopped at a breakpoint. How do I enable it?
By adding support for 64bit (arm64) in your target, View Debugging is enabled for 64bit devices (iPhone 5s, iPhone 6 and iPhone 6 Plus)
In your target build settings make sure under Architectures that standard architectures is checked $(ARCHS_STANDARD), and under Valid Architectures you have arm64.
