In my storyboard view these white bars appeared at the bottom of every view. I can't remember what I did when they appeared, the only thing I can think of was that I tried to add a bar button but then deleted it, so maybe that created some sort of bar. However the bar doesn't show up when running the app in the simulator, it just has a visual in the storyboard.
Does anyone know what it is / why it appeared? and also how can I get rid of it. I got rid of a few by changing the view heights and then changing them back, but when trying to do the same in the first view when I clicked the white bar they all appeared again on every view.
Also, I've noticed some are within the view and some are an extension.
