This is going to be another day where I get to play with SwiftUI because I can’t get any real work done right now and am dealing with lots of interruptions.
This morning, I returned to yesterday’s mouse inventory sample to try to get my rounded corners working. Several people suggested that I implement my interface using a
ZStack and a
Rectangle, so I tried that first.
To my surprise, the
Rectangle expanded my
VStack and I haven’t to date figured out how to constrain its size to be no more than its sibling. I wanted the rectangle to grow weakly instead of pushing the title and total items towards the edge of the parent view, the way it did in this screenshot:
Here’s what it looks like without the monster-sized
Rectangle, which I think is a much more appealing layout:
So instead, after messing around a bit, it occurred to me that everything is a view or at least everything is kind of view-ish and if so, then I could possibly apply my corner rounding to
Color, which I did.
And surprise, this is what I got:
Isn’t that cool?
Although the final layout is exactly what I wanted, if you think about it, it’s not that intuitive that system uses tight placement for this and lax spacing for the one with the
In fact, as a developer, I’m not happy about not having direct control over the tightness of either layout or an obvious way to relate
ZStack siblings. If there’s a way to describe how much content hugging I want in a
ZStack layout and how to prioritize which item in that layout should guide the others, I haven’t discovered it. If you have, please let me know!
I’m still trying to learn to best use the deeply mysterious
Length (and, no, don’t tell me “it’s just
CGFloat“, because clearly it isn’t “just” that with all the
UnitPoint stuff, and so forth) and apply layout relationships. Today, time allowing, I’d certainly like to learn more about the mysterious
View created from a swift tuple of
View values and see where it is used, the
ForEach, which computes views on demand,
EquatableView, and so forth.
