In this short Swift code example, you will learn how to declare a function that can take variadic parameters. We use a variadic parameter to specify that the parameter can be passed a varying number of input values when the function is called.
The below code example will cover:
- Declare a function with variadic parameters,
- Call a function with variadic parameters by passing in two value,
- Call a function with variadic parameters by passing in three values.
Variadic Parameters Example in Swift
// Declare a function that can take variadic parameters func printOutFriendNames(names: String...) { for name in names { print(name) } } // Call the printOutFriendNames with two parameters printOutFriendNames("Sergey", "Bill") // Call the function with more parameters printOutFriendNames("Sergey", "Bill", "Max")
