Unable to open the Encrypted Kingdom with a debugger attached to the process. Mistake

How can I prevent this error when my application crashes while keeping my rights encrypted?

I noticed that the sample projects provided by Realm works great, why is my exception an exception?

Unable to open the encrypted Kingdom with a debugger attached to process *** Application terminated due to uncaught exception "RLMException", Reason: "Unable to open the encrypted Kingdom with a debugger attached to the process

The instructions say that I should set " REALM_DISABLE_ENCRYPTION = YES ", but where do I do that? Is there a way to get around this so that I can still debug the encrypted version? Is value set to NO when loaded into app store?
