Carthage: Option to check that built dependencies are up to date

[olejnjak]

Hi,

I'd like to ask if there is an option to check that my locally built dependencies are up to date. I don't mean if they are using the latest version available (carthage update).

For several reasons we ignore the whole Carthage directory in gitignore so the case would be that the project uses some dependency in version let's say 1.0.0. Whole team works on it and someone updates it to 1.0.1 so Cartfile.resolved is updated. If in 1.0.1 version is no breaking change other wouldn't notice.

My idea would be to store a copy of Cartfile.resolved in Carthage directory so we can add a build phase script which compares actual Cartfile.resolved and the version in Carthage directory, which would be almost similar to the behavior that Cocoapods do.

Thanks

So there's a version file written for each build, for use with the --cache-builds flag (documented here) which can be passed to both bootstrap and build. When it detects that you're up to date it will skip building a dependency. That's not exactly what you want, as there's no command to check the cache values without a build being run, but the code exists so it could be a future enhancement to extract the code to run by itself in a separate command, and verify that bootstrap == the cache value.

In the meantime if you get in the habit of running a bootstrap with '--cache-builds' you can at least run it without fear of waiting for redundant builds

Yep we use --cache-builds as this is the main reasons we switched from Cocoapods. If I find a while to look into this I could try to implement it if it would be a desired enhancement.

YES! Thanks!
