Does anyone have an idea what's going on here? \r\n\r\nThe timer starts but no matter what I do it wont stop.\r\n\r\n```swift\r\nfunc animateStatusIcon(stop: Bool? = nil){\r\n        \r\n        let icon = NSImage(named: \"statusIcon\")\r\n        let iconActive = NSImage(named: \"statusIconActive\")\r\n        \r\n        let timer = Timer.every(0.4.seconds) {\r\n            self.statusItem.image = icon\r\n            Timer.after(0.2.seconds) {\r\n                self.statusItem.image = iconActive\r\n            }\r\n        }\r\n            \r\n        if(stop == true){\r\n            print(stop!)\r\n            print(\"should stop now\")\r\n            timer.invalidate()\r\n        } else  {\r\n            print(stop)\r\n            print(\"start\")\r\n            timer.start()\r\n        }\r\n        \r\n    }\r\n```\r\n","author":{"url":"https://github.com/benpixel","@type":"Person","name":"benpixel"},"datePublished":"2017-05-10T15:53:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/36/SwiftyTimer/issues/36"}
