UITable won't load this class is not key value coding-compliant for the key salesDatatext.'

Question

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key salesDatatext.'

Crashes at upon loading this screen. Is the problem because I'm expecting a mixture of text and integers back, or should I be looking for integers?

I'm lost. Please help. I am new the iOS realm and especially Swift. I apologize for asking a dumb question but just assume I'm slow and will more than likely follow up on your comments with more questions. Please be patient with the noob.
