Initializer

init(_:value:total:)

Creates a progress view for showing determinate progress that generates its label from a string.

Declaration 宣言 

init<S, V>(_ title: S, value: V?, total: V = 1.0) where Label == Text, CurrentValueLabel == EmptyView, S : StringProtocol, V : BinaryFloatingPoint
Available when Label conforms to View and CurrentValueLabel conforms to View.

Parameters パラメータ

title

The string that describes the task in progress.

value

The completed amount of the task to this point, in a range of 0.0 to total, or nil if the progress is indeterminate.

total

The full amount representing the complete scope of the task, meaning the task is complete if value equals total. The default value is 1.0.

Discussion 議論

If the value is non-nil, but outside the range of 0.0 through total, the progress view pins the value to those limits, rounding to the nearest possible bound. A value of nil represents indeterminate progress, in which case the progress view ignores total.

This initializer creates a Text view on your behalf, and treats the title similar to init(verbatim:). See Text for more information about localizing strings.
