Cell heights "wrong on load" when changing heights at runtime

Question

My current project nicely shows changing the height of cells, when you select a cell¹. Everything is perfect.

But, in my current code, when you first launch the app, the heights are wrong.

As soon as you select/unselect some rows or perhaps scroll, everything is perfect.

I can't find the problem. Already tried tableView.reloadData() in viewDidAppear, doesn't help. Any ideas? What could cause this?

¹ By the way if you're just starting with autolayout the example data is from the popular demo of how to make a (static) variable height cell at: appcoda.

Answer 1

Use

reloadSections(NSIndexSet(index: 0), withRowAnimation: .Automatic)

instead of reloadData()
