I need to implement pulse animation which is currently display in current location of esrimap. I need to show this animation in marker. Is there any way to do it?

Thank you for your question! Creating a pulsing marker similar to the "current location" marker is pretty similar to the method outlined here: Make a pulse animation in AGSPictureGraphics

You would create a symbol using a picture marker symbol which is a blue circle, then set up a timer to vary the size. Here's an example using a two simple marker symbol combined into an `AGSCompositeSymbol`; the size of the blue circle is changed when the timer fires:

(view in My Videos)

A rough outline of the code:

var symbolToPulse:AGSSimpleMarkerSymbol!

...

symbolToPulse = AGSSimpleMarkerSymbol(style: .circle, color: .blue, size: 18.0)

let sms2 = AGSSimpleMarkerSymbol(style: .circle, color: .red, size: 12.0)

let compositeSym = AGSCompositeSymbol(symbols: [symbolToPulse, sms2])

pulser = AGSGraphic(geometry: mapPoint, symbol: compositeSym, attributes: nil)

...

timer = Timer.scheduledTimer(timeInterval: 0.1,

target:self,

selector: #selector(updateSize),

userInfo: nil,

repeats: true)

...

let startSize: CGFloat = 18.0

let endsize: CGFloat = 36.0

...

func updateSize() {

var size = symbolToPulse.size + 1.0

if size > endsize {

size = startSize

}

symbolToPulse.size = size

}

Hope that helps!
