# instanceDelay

Specifies the delay, in seconds, between replicated copies. Animatable.

## Declaration

```swift
var instanceDelay: CFTimeInterval { get set }
```

## Discussion

Discussion The default value is 0.0, meaning that any animations added to replicated copies will be synchronized. The following code shows a replicator layer being used to create an animated activity monitor. The replicator layer creates 30 small circles forming a larger circle. The source layer, circle, has a 1 second animated fade out and each of the copies offsets the time of the animation by 1 / 30 seconds. let replicatorLayer = CAReplicatorLayer()       let circle = CALayer() circle.frame = CGRect(origin: CGPoint.zero,                       size: CGSize(width: 10, height: 10)) circle.backgroundColor = NSColor.blue.cgColor circle.cornerRadius = 5 circle.position = CGPoint(x: 0, y: 50) replicatorLayer.addSublayer(circle)       let fadeOut = CABasicAnimation(keyPath: "opacity") fadeOut.fromValue = 1 fadeOut.toValue = 0 fadeOut.duration = 1 fadeOut.repeatCount = Float.greatestFiniteMagnitude circle.add(fadeOut, forKey: nil)

let instanceCount = 30 replicatorLayer.instanceCount = instanceCount replicatorLayer.instanceDelay = fadeOut.duration / CFTimeInterval(instanceCount)       let angle = -CGFloat.pi * 2 / CGFloat(instanceCount) replicatorLayer.instanceTransform = CATransform3DMakeRotation(angle, 0, 0, 1) The following illustration shows the result of the above code:
