Answer 1

Use facebook POP animation For drop dragged view to resting with animation

private func resetViewPositionAndTransformations() {        

    let resetPositionAnimation = POPSpringAnimation(propertyNamed: kPOPLayerTranslationXY)
    resetPositionAnimation.fromValue = NSValue(CGPoint: CGPoint(x: dragDistance.x, y: dragDistance.y))
    resetPositionAnimation.toValue = NSValue(CGPoint: CGPointZero)
    resetPositionAnimation.springBounciness = cardResetAnimationSpringBounciness
    resetPositionAnimation.springSpeed = cardResetAnimationSpringSpeed
    resetPositionAnimation.completionBlock = {
        (_, _) in
        self.layer.transform = CATransform3DIdentity
    }

    layer.pop_addAnimation(resetPositionAnimation, forKey: "resetPositionAnimation")

    let resetRotationAnimation = POPBasicAnimation(propertyNamed: kPOPLayerRotation)
    resetRotationAnimation.fromValue = POPLayerGetRotationZ(layer)
    resetRotationAnimation.toValue = CGFloat(0.0)
    resetRotationAnimation.duration = cardResetAnimationDuration

    layer.pop_addAnimation(resetRotationAnimation, forKey: "resetRotationAnimation")

    let overlayAlphaAnimation = POPBasicAnimation(propertyNamed: kPOPViewAlpha)
    overlayAlphaAnimation.toValue = 0.0
    overlayAlphaAnimation.duration = cardResetAnimationDuration
    overlayAlphaAnimation.completionBlock = { _, _ in
    }
    overlayView?.pop_addAnimation(overlayAlphaAnimation, forKey: "resetOverlayAnimation")

    let resetScaleAnimation = POPBasicAnimation(propertyNamed: kPOPLayerScaleXY)
    resetScaleAnimation.toValue = NSValue(CGPoint: CGPoint(x: 1.0, y: 1.0))
    resetScaleAnimation.duration = cardResetAnimationDuration
    layer.pop_addAnimation(resetScaleAnimation, forKey: "resetScaleAnimation")
}
