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")
