Swift 无法调用非函数类型[UIColor]的值

我已将此代码写入Swift，但最后一行代码返回此错误消息：

无法调用非函数类型“[UIColor]”的值

你犯了一些语法错误<代码>颜色（posicion）应该是

颜色[posicion]

struct Colores {
  let colores = [UIColor(red: 210/255.0, green: 90/255.0, blue: 45/255.0, alpha: 1),
    UIColor(red: 40/255.0, green: 170/255.0, blue: 45/255.0, alpha: 1),
    UIColor(red: 3/255.0, green: 180/255.0, blue: 90/255.0, alpha: 1),
    UIColor(red: 210/255.0, green: 190/255.0, blue: 5/255.0, alpha: 1),

    UIColor(red: 3/255.0, green: 50/255.0, blue: 90/255.0, alpha: 1)]


  func regresaColorAleatorio() -> UIColor{
    let posicion = Int(arc4random()) % colores.count
    return colores[posicion]
  }
}

嗯，我想这是因为你试图调用

colors（position）

，这不是一个函数（正如错误所说）。另外请注意，我修复了您对非英语变量的滥用。嗯，我想这是因为您试图调用
