Thanks, it look promising. But if I use this code (filled dots with {print ("hello")} and Text("..."), app hangs up and prints in console:
2020-11-20 11:44:39.064295+0100 GlyphDesigner[45633:2671193] [Layout] Unable to simultaneously satisfy constraints:
"<NSAutoresizingMaskLayoutConstraint:0x60000119abc0 h=-&- v=-&- _NSTextContentView:0x7fee4561c870.minX == 0 (active, names: '|':NSTextView:0x7fee45673c80 )>",
"<NSAutoresizingMaskLayoutConstraint:0x60000119ada0 h=-&- v=-&- H:[_NSTextContentView:0x7fee4561c870]-(380)-| (active, names: '|':NSTextView:0x7fee45673c80 )>",
"<NSAutoresizingMaskLayoutConstraint:0x60000119ae90 h=--& v=--& NSTextView:0x7fee45673c80.width == 318 (active)>"
)
Will attempt to recover by breaking constraint
<NSAutoresizingMaskLayoutConstraint:0x60000119ada0 h=-&- v=-&- H:[_NSTextContentView:0x7fee4561c870]-(380)-| (active, names: '|':NSTextView:0x7fee45673c80 )>
Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens. And/or, set a symbolic breakpoint on LAYOUT_CONSTRAINTS_NOT_SATISFIABLE to catch this in the debugger.
But I have no idea where to set constrains in this case.

I hope this is an ID: FB15716546
Those circles are defined in brown noise random positions and sizes, but generated PDF has visible grid, many circles are became elipses. Smallest circle in picture has size 1pt x 1pt.
Instead of using GeometryReader and SwiftUI structs for dot shape, I used Canvas and draw paths into its context
For now like this, in a simplest way
struct ContentView: View {
@ObservedObject var manager = Manager()
var body: some View {
...
VStack {
ScrollView([.horizontal, .vertical]) {
DotTestView(dots: $manager.dots)
.frame(width: manager.size.width,
height: manager.size.height)
}
HStack {
Button(action: {
Task {
await manager.updateDots(in: manager.size)
}},
label: {Text("start")})
Button(action: {
print ("stop")},
label: {Text("How to Stop")})
}
}
...
}
}
Manager keeps all configuration data, has @Published var dots:[Dot]. Simple as that.
And a problem is that Rainbow Wheel does not allow me to touch any Button. I suspect:
@MainActor
public struct DotGenerator {....}
but I don't know how to make it different way in Swift6
Bindings in superview was defined inside body.
