Image in Tableviewcell Swipe Action

Image in TableViewCell swipe action

In the second image, the green is the UIContextualAction's backgroundColor and the white is the tintColor.

The image is treated as a template image — that is, its colors are ignored, and instead it is drawn transparent where your image is transparent, and drawn opaque with the tintColor where your image is opaque.

So, basically you would need to reverse your settings: set the background color to white and change the tint color to the darker green shown in your image. Setting the tint color is not easy, but you could do it, for example, in your app delegate didFinishLaunching using the appearance proxy, as suggested here (though this may have other unwanted side effects):

UIImageView.appearance(
    whenContainedInInstancesOf: [UITableView.self])
        .tintColor = // whatever that green is
