iOSOpenDev command line tool build error

Those days, I upgraded my Xcode to XCode6. Then when I compiling a command line tool, it gave me 1 error that

target specifies product type 'com.apple.product-type.tool', but there's no such product type for the 'iphoneos' platform

1)
sudo xcode-select -s PATH_TO_XCODE

2)
sudo xcodebuild -license
xcodebuild -license

Reinstall iOSOpenDev and it should work

Cocoa
