GMSMapView animateToCameraPosition zoom in - zoom out animation

I think there is no direct way you can archive the same animation in the Google Maps iOS SDK.

A workaround can use iOS's dispatch_after method, first you can define a method to delay how many seconds you want:

func delay(#seconds: Double, completion:()->()) {    let popTime = dispatch_time(DISPATCH_TIME_NOW, Int64( Double(NSEC_PER_SEC) * seconds ))    dispatch_after(popTime, dispatch_get_main_queue()) {        completion()    }}

Then you can zoom out your camera, move to a location, then zoom in with the delay method:

delay(seconds: 0.5) { () -> () in    var zoomOut = GMSCameraUpdate.zoomTo(kGMSMinZoomLevel)    mapView.animateWithCameraUpdate(zoomOut)    delay(seconds: 0.5, { () -> () in        var vancouver = CLLocationCoordinate2DMake(49.26,-123.11)        var vancouverCam = GMSCameraUpdate.setTarget(vancouver)        mapView.animateWithCameraUpdate(vancouverCam)        delay(seconds: 0.5, { () -> () in            var zoomIn = GMSCameraUpdate.zoomTo(kGMSMaxZoomLevel)            mapView.animateWithCameraUpdate(zoomIn)        })    })}

You use your own zoom value, I use kGMSMinZoomLevel and kGMSMaxZoomLevel here.

Swift 4:

   func delay(seconds: Double, closure: @escaping () -> ()) {    DispatchQueue.main.asyncAfter(deadline: .now() + seconds) {        closure()    }  }

Then call it :

    delay(seconds: 0.5) { () -> () in            let zoomOut = GMSCameraUpdate.zoom(to: 10)            self.mapView.animate(with: zoomOut)            self.delay(seconds: 0.5, closure: { () -> () in            var vancouver = CLLocationCoordinate2DMake(49.26,-123.11)            var vancouverCam = GMSCameraUpdate.setTarget(vancouver)            self.mapView.animate(toLocation: vancouverCam)            self.delay(seconds: 0.5, closure: { () -> () in                 let zoomIn = GMSCameraUpdate.zoom(to: 15)                 self.mapView.animate(with: zoomIn)                })            })        }
