I've cloned this iOS application from github and tried running carthage with carthage update as outlined in the documentation. However when I do, I get an error stating (in fact, this is my whole terminal output):
Deans-MacBook-Air:SwiftWeather deang$ carthage update

The following build commands failed:

Code Sign error: No code signing identities found: No valid signing identities (i.e. certificate and private key pair) matching the team ID “(null)” were found.
CodeSign error: code signing is required for product type 'Framework' in SDK 'iOS 8.4'
A shell task failed with exit code 65:

Deans-MacBook-Air:SwiftWeather deang$
And the Cartfile looks like this:
github "Alamofire/Alamofire"
github "SwiftyJSON/SwiftyJSON"
Now I don't know if this is specific to the project (though I don't think so, it's quite a popular one and no one else seems to be complaining). So I'm inclined to think it's something I'm doing wrong or something that's wrong with my environment.
You can build/install the App without paying on Xcode 7, just login in your Apple ID into Xcode.
