XCODE auto save code when build and run?

Question

How to tell Xcode to save the source code automatically without prompting, each time I hit on the build and run?

Answer 1

1. Xcode preferences
2. Pick 'Building' tab
3. Lower right corner "For unsaved files:" pick "Always save".

Answer 2

Xcode Preferences → Building → Build Options → For Unsaved Files → Always Save?

Answer 3

it seems this is the default behaviour in the current xcode 5. hopefully it will return so we can turn it OFF and dont have this painfully slow rebuild.
