Discussion
When you display a template image, use this method to set the tint color to apply to that image. With a template image, WatchKit uses only the alpha channel of the image to define a shape. To create a template image from an existing image, call the withRenderingMode(_:) method on an existing UIImage and specify the UIImage.RenderingMode.alwaysTemplate rendering mode.
An image object applies the tint color only when it contains a single template image. It does not apply the tint color to animated images or images that are not configured as template images.
