This folder contains ObjectBox.json, a Chartage "index" for binary frameworks. The advantage of using binary distribution is that those are slimmer than the "github" definition. Using "binary" instead, never causes Carthage to check out the Git repository. Thus updates are faster and less disk space is used.
Warning
The Carthage release is deprecated. See the root README for more details.
In your Cartfile, you typically add a line like this:
binary "https://raw.githubusercontent.com/objectbox/objectbox-swift/master/cartspec/ObjectBox.json"
