问题
So I migrated my AppIcons and LaunchImages to Images.xcassets, which is working fine it seems. But I made some modifications to the launch images, and now I went to commit the changes (I'm using a local-only git repo), and it seems Images.xcassets is not allowed to be committed to source control? Right-clicking on it, all the source control options are greyed out. And it doesn't show up in Xcode 5's new "global" commit dialog.
Seems ridiculous not to allow the assets file to be committed, am I missing something?
回答1:
This is most likely a bug in Xcode. Please file a bug report with Apple: http://bugreport.apple.com
As a workaround use the "global" commit dialog and select "File View" in the top of the side bar. The relevant files should then show up.

Almost 2 years later, the same functionality exists for Xcode 7.1. The workaround that Matthias offers still allows you to upload assets.xcassets.

Quitting the Xcode & reopening the project again worked!

An alternative could be to try something along the lines of:
cd /to/the/folder/
git ls-files --others --exclude-standard | grep .imageset | xargs git add
git commit...
