Why are you adding imageViews onto self.view 12:02, but constraint it to contentView anchors? I guess we should add imageViews onto contentView

Thanks. Great video. :)

I've been doing programmatic UIKit for a few months now and it's really strange to me why you have to set the width and height after already constraining all for sides.

Interestingly, you set `hConst = UILayoutPriority(50)` which is identical to

Apple's documentation says this: " When you send a systemLayoutSizeFitting(_:) message to a view, the size fitting most closely to the target size is computed. This priority is quite low. It’s generally not appropriate to make a constraint at exactly this priority. You want to be higher or lower."

So I suppose it would be better to set it higher or lower. In any case, `priority` is a new concept for me, so thanks for teaching me this. It's already coming in handy as I came here trying to solve a particular problem.

Do you know how I can have the same kind of layout but with scaleAspectFit? I want the images to not get cut and take the whole width of the screen. For that, the height of the image would have to be variable, so I can't set a height constraint, but without a height constraint the images aren't placed one right after the other anymore.

Can you do videos on programmatic CollectionViews?
