Pass an array to a function in Swift throwing invalid parameter type error -

pretty basic question here has me stuffed...

i'm trying call function (defined in class) using method:

 var idarray = profile.getidarray(globals.friendlist);

where globals.friendlist array of profiles (i.e. [profile?] )

now here function .getidarray

func getidarray(inputarray:[profile?]) -> [string] {   //blah - code returns array of strings }

whenever try compile keep getting following error:

cannot invoke 'getidarray' argument list of type '([profile?])'

now here i'm confused - because i'm pretty function is accepting [profile?] parameter type!

what's going wrong - there introduced in swift unaware of?

you invoking getidarray type method. missing class or static keyword in func declaration:

class func getidarray(...  // if profile class  static func getidarray(... // if profile struct or enum
