reloadData() is not reloading the data in a UITableView

I have a view controller with two table views in it and all their data comes from a single object. The second table view has a TextView in it that I can use to change the model object. When I enter text in the TextView, the top TableView (without the text field) updates, but not the bottom.

Tough to say what exactly is causing the problem, but it seems to be a timing issue.

In ViewController, change your didSet to this:

var timecard: Timecard? {didSet {
    if self.isViewLoaded {
        DispatchQueue.main.async {
            self.employeeTableView.reloadData()
            self.timecardTableView.reloadData()
        }
    }
}}

In your minimal example, that seems to fix the issue.

Without spending a lot more time on it, my guess would be that you've got a closure that's holding onto the cell being edited, preventing the table view from reloading? Maybe something similar to that.

On a side note -- you've got some rather unusual stuff going on. Generally a bad idea to assign things like this:

weak var viewController: ViewController?

And, it looks like your closures could be problematic in a couple ways (row index can change, looks like you're creating strong references that can cause retain cycles, etc).
