Answer 1

I had the same problem, after hours of searching, it turned out the problem was because in-call or hotspot status bar was toggled, (hotspot is on, in a phone call), to fix the problem, in appdelegate I added:

    func application(application: UIApplication, willChangeStatusBarFrame newStatusBarFrame: CGRect) {
    let windows = UIApplication.sharedApplication().windows

    for window in windows {
        window.removeConstraints(window.constraints)
    }
}
