Are you sure that you’re using realm-cocoa 10.6? I see this in your log: Realm Cocoa v10.0.0-beta.5

[Muhammad_Awais]

yes i am installing pod realmSwift and i have updated it too

[Andrew_Morgan]

You should see something like this in the logs if you’re using 10.6

If you’ve been making schema changes then you may have confused sync. Try deleting the app from the simulator and removing sync from your backend Realm app and then enable it again. When you install the app again, both sides of the sync will start from a clean point.

[Andrew_Morgan]

Consider switching from Cocoa Pods to SPM – I find it much easier to work with.

[Muhammad_Awais]

can you send me latest SPM for realm

[Andrew_Morgan]

In Xcode, choose the option to add a new dependency…

… set the repo to https://github.com/realm/realm-cocoa.git and the version to 10.6 or 10.7. You can then remove the Pod

Thanks It has been resolved after remaking the models and schema.
