I would like to create a widget with a half-circular progress bar.
Like this:
struct HalvedCircularBar: View {
@State var progress: CGFloat = 0.5
var body: some View {
VStack {
ZStack {
Circle()
.trim(from: 0.0, to: 0.5)
.stroke(Color.blue, style: StrokeStyle(lineWidth: 12.0, dash: [8]))
.frame(width: 200, height: 200)
.rotationEffect(Angle(degrees: -180))
Circle()
.trim(from: 0.0, to: progress/2)
.stroke(Color.blue, lineWidth: 12.0)
.frame(width: 200, height: 200)
.rotationEffect(Angle(degrees: -180))
Text("\(Int(self.progress*100))%")
.font(.custom("HelveticaNeue", size: 20.0))
}
}
}
}
It's ok in the playground and app, but it cannot appear in the widget. When I removed the ".trim(from: 0.0, to: 0.5)" ,the circle appeared in the widget.
Why is the trim() method not available in ios14 widget ?
