How do I get an array order number of the text give in that array? [duplicate]

We can use an array [String] to get the number text from its number.

let number = ["One", "Two", "Three", "Four", "Five"]

e.g. number[0] means "One"

How do I get a simple order number of the text in the array having just its text ("Five" etc.) using Dictionary?

I tried a function like that:

let number = ["One", "Two", "Three", "Four", "Five"]
func getNumber(_ numberText: String) {
    if numberText == "One" {
        print(0)}
    if numberText == "Two" {
        print(1)}
    if numberText == "Three" {
        print(2)}
    if numberText == "Four" {
        print(3)}
    if numberText == "Five" {
        print(4)}
}

getNumber("Two")

But it has nothing common with the initial array at the top. Please help guys 🙏
