code 65 result after getting a Carthage update failure

[ghost]

How can I fix this?
What does mean the code 65, "failed with exit code 65"?

You can take a look at the Carthage log to know what's going on:

tail /var/folders/zv/vlyntqt95mqg59jkprg_qghm0000gn/T/carthage-xcodebuild.1C5NyQ.log

If you're on Xcode 8, I'm fairly certain it's related to the fact that v2.2.5 is neither Swift 2.3 compliant, nor has the SWIFT_VERSION flag set to 2.3. The team is working on it, in the meantime, you can try using the Charts2.2.5-swift2.3 branch.
