init(timerInterval:countsDown:)
Creates a progress view for showing continuous progress as time passes.
Declaration
nonisolated init(timerInterval: ClosedRange<Date>, countsDown: Bool = true)Parameters
- timerInterval:
The date range over which the view progresses.
- countsDown:
If
true(the default), the view empties as time passes.
Discussion
Use this initializer to create a view that shows continuous progress within a date range. The following example initializes a progress view with a range of start...end, where start is 30 seconds in the past and end is 90 seconds in the future. As a result, the progress view begins at 25 percent complete.
struct ContentView: View {
let start = Date().addingTimeInterval(-30)
let end = Date().addingTimeInterval(90)
var body: some View {
ProgressView(interval: start...end
countsDown: false)
}

By default, the progress view empties as time passes from the start of the date range to the end, but you can use the countsDown parameter to create a progress view that fills as time passes, as the above example demonstrates.
The progress view provided by this initializer omits a descriptive label and provides a text label that automatically updates to describe the current time remaining. To provide custom views for these labels, use init(value:total:label:currentValueLabel:) instead.
