update command should have option to only build those that were updated

[marcvanolmen]

--only-build-modified

• With this option, After fetching and checking out, the build command should build only those that fetched actually new commits.

So much this!

[masa-beheim]

Great suggestion. :thumbsup: Would save a lot of time.

+1 another option should be to specify the framework to update: carthage update Alamofire

[NachoSoto]

@sprint84 that's #610

[devashish2203]

+1 for this.. would save a lot of time specially on CI systems

[NachoSoto]

This was done in #972.

Oops my bad, I misread the issue again! At least now you'll be able to do this manually :)

@NachoSoto How are we able to do this manually?

You're now able to specify a list of dependencies to update/build. carthage update Alamofire.

[damirstuhec]

@mdiep Thanks. I knew about it but forgot that it also builds the dependencies of the dependency getting updated, so I thought it doesn't work as expected.

[nirmalchoudhari]

is it working?

[tmspzz]

this is the same as --cache-builds if I understand correctly. So I would say yet, it works.
