Can you pass a typed array to a function within an enum in swift? -

in swift app, i've created enum function takes array of clbeacon objects it's argument (i.e., [clbeacon]). no clang errors enum, when try use enum, clang complains can't invoke function argument list of ([clbeacon]). here's code:

enum beaconarraystate {      case noobjectonscreen, firstobjectonscreen, firstobjectoffscreen      mutating func check(beacons: [clbeacon]) -> beaconarraystate {          switch self {              case firstobjectonscreen:                 return .firstobjectonscreen             case firstobjectoffscreen:                 return .firstobjectoffscreen             case noobjectonscreen:                 if beacons.count > 0 {                     println("push screen associated beacon \(beacons[0].minor)")                 }                 return .noobjectonscreen         }     } } var beaconarraystate: beaconarraystate = .noobjectonscreen  func beaconmanager(manager: anyobject!, didrangebeacons beacons: [anyobject]!, inregion region: clbeaconregion!) {     let knownbeacons = beacons.filter{$0.proximity != clproximity.unknown}     //send updated beacons array perform parsebeacons     nsnotificationcenter.defaultcenter().postnotificationname("updatenotificationpriorities", object: knownbeacons)      beaconarraystate = beaconarraystate.check(knownbeacons [clbeacon]) } 

this gives: error - cannot invoke 'check' argument list of type '([clbeacon])'

the code in case statements irrelevant , not yet determined, why error on invocation?

the problem code calling check method statically while function not static @ all. check function not mutating function dont need mutating keyword. make work make follow change beaconarraystate = beaconarraystate.check(knownbeacons [clbeacon]) or if want check method mutate change :

mutating func check(beacons: [clbeacon]) {      switch self {      case firstobjectonscreen:         self = .noobjectonscreen     case firstobjectoffscreen:         self = .firstobjectoffscreen     case noobjectonscreen:         if beacons.count > 0 {             println("push screen associated beacon \(beacons[0].minor)")         }         self = .noobjectonscreen     } } 

then call beaconarraystate.check(knownbeacons [clbeacon]) , becaonarraystate new value
