AppCode lets you compare files in two folders against their file size, content, or timestamp. The differences are displayed in the Differences Viewer for Folders:

Use the following toolbar buttons to filter the list:
: click to display files that are present in the left folder, but are missing from the right one.

Compare different files in two folders
Sometimes a file may be present in one folder, and another file with a similar name in the other folder (for example, VCS_library_1.4 and VCS_library_1.5). These may be versions of the same file that you want to compare. Also, there may be a situation when you think a file was renamed, but is otherwise identical to a file in another folder. AppCode lets you compare two files, one of which is present in the right folder, and another one in the left even though such files are treated as different entities.
Select the files you want to compare in the left and the right pane.
Click the Compare New Files with Each Other icon on the toolbar. The differences between the selected files will be displayed in the bottom pane.
Compare any text sources
Apart from comparing files' or folders' contents, you can open an empty Differences Viewer and paste any text or drag files into the right and left panels to compare. This can be useful, for example, if you want to compare an application's console output with the output of the same application albeit a little modified.
Press ⌃⇧A and start typing to locate the Open Blank Diff Window action.
Paste any text you want to compare in the left and right panels.
- Assign a shortcut for the 'Open Blank Diff' action
In the Preferences dialog ⌃⌥S select Keymap and locate this action under Version Control Systems | Diff & Merge.
- Swap sides
You can swap sides in the Diff Viewer by pressing the icon on the toolbar.
