Probably a bad call to have individual cells observing the model. The point of the UITableViewDataSource protocol is to give you a place to handle changes in the model without tying it directly to the view components. Cells can be dequeued (effectively removed) and dequeued dynamically by the tableview.

If you set up a separate object as the tableview's datasource and to receive notifications of change from the model then you can decouple your model from your view.

This is essentially the Model > View > Controller trinity we are intended to write our code in the image of. Remove the dependency between your UI and the model by putting a controller object in the middle.

Read the guide for better explanation and guidance on this.

If this answer doesn't help the exact problem could you expand on the issue you're having?
