How to Iterate over Words in String in Swift ?

Answer

To iterate over words in a string in Swift, you can use the components(separatedBy:) method to split the string into words, then use a loop to iterate over the resulting array.

✐ Examples

1 Iterate Over Words in String Using Space Separator

In this example,

We create a string named str with a string value.
We use the components(separatedBy:) method to split the string into an array of words using a space character as the separator.
We use a for loop to iterate over each word in the array.
Inside the loop, we print each word to standard output.

Swift Program

import Foundation

let str = "Hello World from Swift"
let words = str.components(separatedBy: " ")
for word in words {
    print(word)
}

Output

Hello
World
from
Swift

2 Iterate Over Words in String Using Comma Separator

In this example,

We create a string named str1 with a string value containing words separated by commas.
We use the components(separatedBy:) method to split the string into an array of words using a comma as the separator.
We use a for loop to iterate over each word in the array.
Inside the loop, we print each word to standard output.

Swift Program

import Foundation

let str1 = "apple,banana,orange,grape"
let words = str1.components(separatedBy: ",")
for word in words {
    print(word)
}

Output

apple
banana
orange
grape
