Getting the error while building the SwiftJSON framework to the Some Xcode project through Carthage Dependency Manager.
Sivaramaiahs-Mac-mini:GZipDemoApp vsoftMacmini5$ carthage update --platform iOS

A shell task (/usr/bin/xcrun xcodebuild -project /Users/vsoftMacmini5/Desktop/GZipDemoApp/Carthage/Checkouts/GzipSwift/Gzip.xcodeproj CODE_SIGNING_REQUIRED=NO CODE_SIGN_IDENTITY= CARTHAGE=YES -list) failed with exit code 72:
xcrun: error: unable to find utility "xcodebuild", not a developer tool or in PATH
I solved that problem by setting the Command Line Tools in Xcode. Go to:
Xcode > Preferences > Locations
And select the command line tool from the dropdown. If you have only one version of Xcode installed, there should be only one option. If you have several versions of Xcode, then you must choose the one you need.
