Exception:

Thread 1: Exception: "
Your application has presented a UIAlertController (<UIAlertController: 0x7fc267851800>) 
	of style UIAlertControllerStyleActionSheet 
		from UINavigationController (<UINavigationController: 0x7fc26b035a00>). 

The modalPresentationStyle of a UIAlertController with this style is UIModalPresentationPopover. 

You must provide location information for this popover through the alert controller's popoverPresentationController. 

You must provide either a sourceView and sourceRect or a barButtonItem.  

If this information is not known when you present the alert controller, you may provide it in the UIPopoverPresentationControllerDelegate method -prepareForPopoverPresentation."

Fix

controller.popoverPresentationController?.sourceView = cell.contentView // fix #56

The popoverPresentationController will be nil on iOS, so this as no effect when on iPhone.
Using the cell.contentView, will have the popover with a callout pointing to the cell from which the event originated. The same applies to Sign out flight and Sign Out All Squadron Cadets.
