How to make Xcode4 stop at NSAssert failure?

Question

Currently, my Xcode4 does not stop at NSAssert failure. How can I make it stop at NSAssert failure again?

Answer 1

Assertions are automatically disabled, by default, in a Release build. If you want assertions to work, do a Debug build, or turn off the Other C Flags build setting where assertions are turned off in the Release build.
