Set sort order for UIStackView

Question

Is it possible to set a sort order for a UIStackView? For example, I want to sort it by time. Each subview has a time property which is just an Int.

I know you can sort a UITableView by sorting the array and then refreshing the table but UIStackView doesn't have delegates and data sources like that so I don't know how to go about this. It just seems to go by the order you add the subviews in which makes it challenging to add a view in the middle without removing everything first.

Why? Because certain tools are made to perform certain tasks. It doesn't mean you can't use them... but you wouldn't use a hammer to screw in a screw. — Fogmeister, Jul 18 '17 at 21:53
Glad I could be of some help :D Good work getting it working :D — Fogmeister, Jul 20 '17 at 15:15
Well I was thinking about how I was going to refresh the data in the view with a refresh control and I was feeling lazy so I refactored it to use a table view. — Marcel, Jul 20 '17 at 15:19

Maybe read the documentation?

The stack view manages the layout of all the views in its arrangedSubviews property. These views are arranged along the stack view’s axis, based on their order in the arrangedSubviews array.

So can a sort this array whenever I want without worrying about performance? – Marcel Jul 18 '17 at 18:47
That is a get only property but reading the documentation did help. – Marcel Jul 18 '17 at 18:57
https://developer.apple.com/documentation/uikit/uistackview/1616232-arrangedsubviews has all the specific information you should need. If you're doing this so often that performance might be an issue, you should use UICollectionView or UITableView – GetSwifty Jul 19 '17 at 00:15

You can remove all arrangedSubviews and add or insert them again in you own order. Make sure this subviews is not hidden, because stackView sort them to head of arrangedSubviews array
