struct SampledAnimation<Value> where Value : AnimatableData

An animation that cycles through a series of frames at a constant interval. To specify the data that the animation samples, set one of the `frames` properties that matches the animated property's type. For example, set the ``SampledAnimation/frames-2j4nj`` property to interpolate <doc://com.apple.documentation/documentation/swift/float> values. The following code designates a ``SampledAnimation`` to animate a propery of type <doc://com.apple.documentation/documentation/swift/float> by specifying the generic typed syntax. The code queues an array of values: `1.0`, `2.0`, and `3.0`. ```swift // Define the animation type. typealias SampledAnimationType = SampledAnimation<Float> // Define the animated property values. let frameArray: [Float] = [1.0, 2.0, 3.0] ``` To determine how fast the animation progresses from frame to frame, define this structure's ``SampledAnimation/frameInterval`` property. The following code specifies a one-second delay between value changes before initializing the animation object. ```swift // Define a one-second frame interval. let interval: TimeInterval = 1 // Create the animation. let sampleAnim = SampledAnimationType( frames: frameArray, name: "sampledAnim1", frameInterval: interval isAdditive: true, bindTarget: .transform, blendLayer: 100, repeatMode: .autoReverse, fillMode: .backwards, trimStart: 1.0, trimEnd: 10.0, trimDuration: 9.0, offset: 2.0, delay: 1.0, speed: 2.0 ) ```
