How to zoom in Xcode on a code window

Question

How do you zoom in to see code better in xcode. I'm looking for a shortcut, and not to change the projects display preferences. Also using CTRL + two fingers on mouse is not suitable as I'm using a multi-monitor set up and that zooms both monitors. I only want to zoom in on the code text. I found another solution here that allows zooming on the storyboard : Storyboard Zoom In/Out Keyboard Shortcut but this doesn't work on any of the code files.

Any ideas?

Answer 1

For XCode 9 and above:

• Use Cmd + + to increase text size
• Use Cmd + - to decrease text size

Answer 2

I'm using xcode 7:
1. Xcode menu-> Preferences.
2. Choose the tab Fonts & Colors.
3. Choose theme on the left side.
4. On the right side cmd+A to choose all type of source.
5. In font field, click to T icon.
6. Choose a font size that you want to set.
