split a string into an array of words in swift

To split a string into an array of words in Swift, you can use the components(separatedBy:) method of the String class. This method splits the string into an array of substrings based on a given delimiter.

In this case, the delimiter we want to use is the white space character (" "), which separates words in a sentence. Here's an example of how to split a string into an array of words:

main.swift
let sentence = "The quick brown fox jumps over the lazy dog"
let words = sentence.components(separatedBy: " ")
print(words) // ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"]
199 chars
4 lines

In this example, we first define a string variable sentence that contains the sentence we want to split into words. We then call the components(separatedBy:) method on sentence and pass in the delimiter as an argument.

The result is an array of strings words, where each element contains a word from the original sentence. We print out words using the print() function to verify that the split was successful.

Note that components(separatedBy:) returns an array of strings, so the resulting array words is of type [String]. If you need to perform additional operations on this array, you can use array methods such as .count and .map().
