Cannot use a predicate that compares dates in Magical Record

Question

I am making a method that will remove all of my NSManagedObjects that were not updated in the last sync.

- (void)removeStaleObjects {

        // Delete obje

It also looks to my that your predicate is formatted correctly. Here are a couple things you can do:

1) When debugging this, print out that predicate. You should see something like:

updatedDate < {some integer value}

Dates are stored as integers under the covers, and a predicate converts it properly as well. If your predicate isn't printable in the debugger, you'll know right away

2) Check your updatedDate type. Make sure that's a date (I trust it's already a date, but you didn't specify in your question)

3) Make sure your Node object has the updatedDate attribute on it.
