keyframeAnimator(initialValue:repeating:content:keyframes:)

Loops the given keyframes continuously, updating the view using the modifiers you apply in body.

Declaration

nonisolated func keyframeAnimator<Value>(initialValue: Value, repeating: Bool = true, @ViewBuilder content: @escaping  @Sendable (PlaceholderContentView<Self>, Value) -> some View, @KeyframesBuilder<Value> keyframes: @escaping (Value) -> some Keyframes) -> some View

Parameters

  • initialValue:

    The initial value that the keyframes will animate from.

  • repeating:

    Whether the keyframes are currently repeating. If false, the value at the beginning of the keyframe timeline will be provided to the content closure.

  • content:

    A view builder closure that takes two parameters. The first parameter is a proxy value representing the modified view. The second parameter is the interpolated value generated by the keyframes.

  • keyframes:

    Keyframes defining how the value changes over time. The current value of the animator is the single argument, which is equal to initialValue when the view first appears, then is equal to the end value of the previous keyframe animation on subsequent calls.

Discussion

Note that the content closure will be updated on every frame while animating, so avoid performing any expensive operations directly within content.
