在函数声明中将函数设置为变量

Set function as variable in function declaration

我想在函数声明中将函数作为变量,而不是在声明的函数中调用该变量。如何在 Swift?

伪代码:

let something = 0

func one() {
    print("one")
}

// Definition
func two( funcVariable: Void, number: Int) {
   print("\(number)")
   funcVariable() // here I want to call variable function 
}

// Call
two(funcVariable: one(), number: somethhing)

怎么做?

感谢示例代码。

操作方法如下:

let something = 0

func one() {
    print("one")
}

// Definition
func two(funcVariable: () -> Void, number: Int) {
   print("\(number)")
   funcVariable()
}

// Call
two(funcVariable: one, number: something)
