Set Target/General/Deployment info to Hide status bar. Set None for Status Bar in VCs in storyboards. Added the following code to all VCs.
override var prefersStatusBarHidden: Bool {
return true
}
Briefly hides status bar but immediately reappears.
Only the prefersStatusBarHidden of the root-level view controller matters — here, the split view controller. The split view controller wants a status bar; it gets a status bar. That is all that matters.
You could try subclassing UISplitViewController, setting prefersStatusBarHidden in your subclass, and using that subclass in the app.
