I\'ve implemented a Today widget for my application +Quotes which displays the day\'s quote within the notification center with the help of these Apple Docs. What I\'d like
Swift 2 version, according to Apple Doc
extensionContext?.openURL(NSURL(string: "foo://")!, completionHandler: nil)
Swift 3 version
extensionContext?.open(URL(string: "foo://")! , completionHandler: nil)
And don't forget to add Custom URL Schemes into Info.plist
Info.plist
