Unable to simultaneously satisfy constraints ranomly

[Ewg777]

CSNotificationView disappears randomly

 Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it. 
    (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
    "<NSAutoresizingMaskLayoutConstraint:0x1f524250 h=-&- v=--& CSNotificationView:0x141d72c0.width == UIView:0x15944d40.width - 320>",
    "<NSLayoutConstraint:0x1f524550 H:|-(4)-[UIActivityIndicatorView:0x1d836340]   (Names: '|':CSNotificationView:0x141d72c0 )>",
    "<NSLayoutConstraint:0x1f524510 H:[UIActivityIndicatorView:0x1d836340(44)]>",
    "<NSLayoutConstraint:0x1f5244d0 H:[UIActivityIndicatorView:0x1d836340]-(5)-[UILabel:0x1d8364c0'Establishing...']>",
    "<NSLayoutConstraint:0x1f524490 H:[UILabel:0x1d8364c0'Establishing...']-(10)-|   (Names: '|':CSNotificationView:0x141d72c0 )>",
    "<NSLayoutConstraint:0x1f524150 'UIView-Encapsulated-Layout-Width' H:[UIView:0x15944d40(320)]>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x1f5244d0 H:[UIActivityIndicatorView:0x1d836340]-(5)-[UILabel:0x1d8364c0'Establishing ...']>

Sample:

      let loader = CSNotificationView(parentViewController: self,
                                  tintColor: UIColor(red: 0, green: 0, blue: 0, alpha: 0.1),
                                  image: nil,
                                  message: message)
      loader.showingActivity = true
      loader.setVisible(true, animated: true, completion: nil)
