Xcode is the primary development tool for an iOS developer. When I was learning mobile development, learning a core set of keyboard shortcuts for Xcode helped take some of the complication out of this dense tool and keep me focused on my work.

You can check out the full Xcode Cheatsheet here.

And below are a few of my favorite Xcode shortcuts:

⌘ B Build
⇧ ⌘ B Analyze
⌘ R Run
⌘ I Profile
⌘ U Test
⇧ ⌘ K Clean
⌃ ⇧ ⌘ W Remove Assistant Editor
⌘ ↩ Show Standard Editor
⌥ ⌘ ↩ Show Assistant Editor
⌃ ⌘ M Show All Issues
