Same here, but only when running in Apple Watch series 4 simulator, iOS is working fine with the latest release

There's not much I can do to help you with just a screenshot of a crash.

I'm seeing the same issue but only when running my app on iOS 9.x. 10.x and above is alright.

Looks like I've found my issue:
In one of my Realm Objects I've declared a variable public var slug: String? however this is normally ignored, on iOS 9 (built with XCode 10) its not being ignored.
I've just put @objc public dynamic var slug: String? and I can create the realm object again without exceptions.

@neoplastic Exactly, my problem was solved identically with what you said, but in my case, I had a var var customGroupedBy: String? that shouldn't be read by Realm, it must just be an object property. To solve that I added this property in ignoredProperties function from Realm and this worked flawlessly

Thanks for the additional info; I can now reproduce this.

Looks like this is actually just #5781, and the fix for that (#5783) was incorrect and only worked by coincidence.

Thanks everyone and @tgoyne . Please let me know when this fixes was live and I will close the issue. Right now setting as non-optional is the only way.
