.hash give EXC_BREAKPOINT (code=EXC_ARM_BREAKBOINT

I'm trying to implement the Hashable protocol on my object using EVCloudKitDao where all properties will be used for the hash by using reflection. For some of the properties I'm getting the error:

EXC_BREAKPOINT (code=EXC_ARM_BREAKBOINT

When I filter out the key's that has this problem, then sometimes key that went ok before will suddenly get this error.

Here is a screenshot of the error:

The entire code that has this problem can be found at: EVReflection.swift

I get the error the moment i request a .hash on an object that has the EVCloudKitDataObject as it's base object.
