**Cartfile**

Cant share cartfile due to pricavcy reasons
We download the binaries using carthage update from artifactory. Binary dependency has been specified in Cartwright file . It normally fails intermittently. Have verified nothing wrong from artifactory;s end

Below is the detailed analysis

CONSOLE: 3:09 crash was in thread 11 (Project.downloadBinaryFrameworkDefinition):
Dictionary.subscript.getter

So, a nil value in a dictionary? (json?)

**Actual outcome**
Carthage did or did not download the binaries from the Artifactory

**Expected outcome**
Carthage should have downloaded the binaries mentioned in the Cartwright file
