在快速抛出无效参数类型错误时，将数组传递给函数

pretty basic question here but it has me stuffed...

这是一个很基本的问题，但它让我很困惑……

I'm trying to call a function (defined in another class) using this method:

我正在尝试使用这个方法调用一个函数(在另一个类中定义):

 var idarray = Profile.getIDArray(Globals.friendlist);

where Globals.friendlist is an array of Profiles (i.e. [Profile?] )

Globals.friendlist是一个配置文件数组(例如[Profile?])

Now here is my function for .getIDArray

这是。getidarray的函数

func getIDArray(inputarray:[Profile?]) -> [String] {
  //Blah - code that returns an array of Strings
}

Whenever I try to compile this I keep getting the following error:

每当我试图编译它时，我总是得到以下错误:

Cannot invoke 'getIDArray' with an argument list of type '([Profile?])'

Now here is where I'm confused - because I'm pretty certain that my function is accepting [Profile?] as the parameter type!

这里我有点困惑，因为我很确定我的函数接受[Profile?]作为参数类型!

What's going wrong - is there something introduced in swift that I am unaware of?

出了什么问题——斯威夫特有什么我不知道的东西吗?

You are invoking getIDArray as a type method. Probably you are missing a class or static keyword in the func declaration:

您调用getIDArray作为类型方法。可能您在func声明中缺少一个类或静态关键字:

class func getIDArray(...  // if Profile is a class

static func getIDArray(... // if Profile is struct or enum
