Code Sample

Provide a code sample or test case that highlights the issue.
If relevant, include your model definitions.
For larger code samples, links to external gists/repositories are preferred.
Alternatively share confidentially via mail to help@realm.io.
Full Xcode projects that we can compile ourselves are ideal!

Version of Realm and Tooling

In the CONTRIBUTING guidelines, you will find a script,
which will help determining these versions.

Realm version: latest

Xcode version: latest

iOS/OSX version: latest

Dependency manager + version: carthage latest

The error message suggests that you have a primaryKey() method on one of your Object subclasses that's returning the name of a property whose type is not Int or String. Can you do a search in your project for a function named primaryKey to see if you've overlooked one?

[sirvon]

found it!....i had a primary key on models I wasn't even using yet...models that wasnt even in the realm file.

All models you've defined are in the Realm file unless you explicitly specify a subset of the schema to use by setting Realm.Configuration.objectTypes.
