Core Data Relationships - Chapter 23

After going through chapter 23, my app isn’t quite working. There is a problem with the photo tags: when I transition to the tags view controller, no tags appear in the table view. I am able to add a new tag at which time all previously added tags show up.

Tags that have been checked seem to still be checked when they finally appear in the table you after forcing their presence by adding a new tag. The data seems to be passed correctly to the tag view controller, but tags are just not showing up when the tag view controller is initially presented.

Driving me crazy. Any ideas?

Figured it out. Missing the updateTags() in TagsViewController.viewDidLoad()
