Any way to show ProgressView() when Done button tapped

My App uses Sprite Kit. When you change the setting in the setting view that requires redraw of the Sprite Kit scene, it takes a couple of seconds to go back to the Sprite View from the Setting View. I want to show a ProgressView() after Done button is tapped to indicate the App is running all right. But ProgressView() does not appear when it is triggered by the tap action of the Done button. Probably because the view is already unloaded or gets inactive. Is there any way of showing ProgressView() when Back/Done button is tapped?
