How to disable animation for changing GMSMarker position in iOS?

Question

According to documentation you can change marker position with animation:

Marker position. Animated.

Do you know how to disable this animation?

Answer 1

Suppose your reference for marker is mainMarker which is a GMSMarker object

var mainMarker:GMSMarker?

And suppose this is your function to change marker position without animation

func changeMarkerWithoutAnimation() {
    mainMarker?.map = nil
    mainMarker = nil
    let changedPosition = CLLocationCoordinate2DMake(22.9734, 78.6569)
    mainMarker = GMSMarker(position: changedPosition)
    mainMarker?.title = "Hello World"
    mainMarker!.map = mapView
}

This will change your marker's position without animation.

Answer 2

As implemented in google maps samples, you should use CATransaction for this purpose.

let changedPosition = CLLocationCoordinate2DMake(22.9734, 78.6569)
CATransaction.begin()
CATransaction.setAnimationDuration(0.0)
marker.position = changedPosition
CATransaction.commit()
