ios - Swift append gives missed argument error -

my code fine before adding color: uicolor existing class. after adding color: uicolor append part of code giving error (missing ',' argument).

i have pasted part of code. please see bottom line error.

import foundation import uikit    class destinationtype {      var name: string                    // name of destination type     var destinations : [destination]    // destinations in type      init (name:string, includedestination:[destination]) {         self.name = name         self.destinations = includedestination     }      class func destinationtypes() -> [destinationtype] {         return [self.summer(), self.winter()]     }      private class func summer() -> destinationtype {          var destinations = [destination]()          destinations.append(destination(name: "antalya", description: "very", imagename: "antalya.png", color: uicolor.greencolor)  

// expected ',' seperator }

if need, find class file below.

import foundation import uikit  class destination {      var name : string     var description : string     var image : uiimage     var color : uicolor      init (name:string, description:string, imagename:string, color:uicolor) {         self.name = name         self.description = description         if let img = uiimage(named: imagename) {             image = img         }          else {             image = uiimage(named: "default")!         }         self.color = color     } } 

greencolor misses parentheses. needs greencolor().

swift's error messages more misleading giving hint wrong :-(
