如何回滚到Xcode 6.4，Carthage

Question

I download Xcode 6.4 from here http://adcdownload.apple.com/Developer_Tools/Xcode_6.4/Xcode_6.4.dmg . Then select previous Xcode for build:

~ xcode-select -s "/Applications/Xcode_6.4.app/Contents/Developer"

But I can't compile libraries with Carthage . I get error:

2015-09-18 19:13:58.057 xcodebuild[13961:788602] stream error: stream error at offset 8: unsupported version number ('1.04')

On other computer after Xcode 7 update, the same issue. Libraries doesn't compile, but errors is different.

~ carthage version
0.8.0

Cartfile:

github "Alamofire/Alamofire" "1.3.1"

Answer 1

I was getting the same error. I just ran the update command with sudo. Here is the full list of steps that worked for me:

• Renamed Xcode 7.x application to Xcode 7
• Downloaded Xcode 6.4.
• Updated Cartfile to: github "Alamofire/Alamofire" "1.3.1"
• Ran the the carthage update with sudo:

 sudo carthage update

Terminal's output:

Januszs-Mac-mini: janusz$ sudo carthage update

*** Building scheme "Alamofire iOS" in Alamofire.xcworkspace
