不能調用非功能型的值的UIColor]

我寫了這個代碼到斯威夫特，但代碼返回此錯誤消息的最後一行：不能調用非功能型的值的UIColor]

不能調用非功能型的價值「[的UIColor]」

import Foundation 
import UIKit 

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: 120/255.0, green: 120/255.0, blue: 50/255.0, alpha: 1), 
     UIColor(red: 130/255.0, green: 80/255.0, blue: 90/255.0, alpha: 1), 
     UIColor(red: 130/255.0, green: 130/255.0, blue: 130/255.0, 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，我想那是因爲你嘗試調用'顏色（位置）'這是不是一個函數（如錯誤說）。還請注意我修復了您在那裏濫用非英語變量的情況。 – nonchip

你犯了一些語法錯誤。 colores(posicion)應該colores[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: 120/255.0, green: 120/255.0, blue: 50/255.0, alpha: 1), 
    UIColor(red: 130/255.0, green: 80/255.0, blue: 90/255.0, alpha: 1), 
    UIColor(red: 130/255.0, green: 130/255.0, blue: 130/255.0, 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] 
    } 
}
