I have seen similar problems reported but find myself unable to fix this. I have datePicker and a segmented control as subviews in a stack, built on the interface builder. These display on the interface builder with the correct white color text but once the app builds on the simulator, it displays as black text. I have tried setting the value for the color in viewDidLoad using: datePicker.setValue(UIColor.white, forKeyPath: "textColor") but with no luck. I'm not sure if the fact they are in a subview is the problem, and I'm just missing a tick box somewhere? It's especially confusing that it seems to display properly on the storyboard but as soon as the app loads it reverts to black. Could this be a bug in Xcode? Many thanks for any help.
