This sample demonstrates how to open a WMS layer from a URL and display it in a map.
How it works
AGSWMSLayer provides an initializer called init(url:layerNames:) that takes a WMS service URL and an array of layer names available in the WMS service. The URL must be the URL to the GetCapabilities endpoint of the WMS Service. The sample loads the WMS Layer using load(completion:) method. And on successful completion, the layer is added to the collection of map's operational layers.
