NSPopover .appearance property is NSAppearance in Swift, not NSPopoverAppearance as per the docs
Raw
gistfile1.swift
// The docs say that the appearance property of an NSPopover should be set to an
// NSPopoverAppearance enum but it actually expects an NSAppearance instance.
// e.g., in an NSViewController subclass:
let popover = NSPopover()
popover.contentViewController = self.storyboard?.instantiateControllerWithIdentifier("someViewController") as? NSViewController
popover.appearance = NSAppearance(named: NSAppearanceNameVibrantLight)
popover.behavior = NSPopoverBehavior.Transient
// etc.
