It's rather very simple. Consider the following Array object.

var names: [String] = ["jack", "rose", "jill"]

In order to obtain the index of the element rose, all you have to do is:

names.index(of: "rose") // returns 1

Note:

• Array.index(of:) returns an Optional.

• nil implies that the element isn't present in the array.

• You might want to force-unwrap the returned value or use an if-let to get around the optional.
