What is the difference between Debug and Release mode ?

HI Amiya,

Debug: When you are running the app in your device, which is connected through wire to your system.

Release: basically for submitting to the apple review / for releasing the app for client review. You can save an .ipa file in this scenario.

Debug mode adds code to the project to allow it to be debugged.

Release mode removes the extra code.

Big difference.

Always do final testing on the device in Release mode.

The Release mode enables optimizations and generates without any debug data, so it is fully optimized. . Lots of your code could be completely removed or rewritten in Release mode. The resulting executable will most likely not match up with your written code. Because of this release mode will run faster than debug mode due to the optimizations.
