Swift – Split lines in a string into an array

Split a string with multiple lines into an array in Swift

To convert a given string with multiple lines into an array of lines in Swift, split the string by new line character using components() method of String class instance.

For example, if you would like to split a given string str by new line character, and get the lines in an array, use the following syntax.

str.components(separatedBy: "\n")

The above method returns the lines of string in an array.

Examples

1. Get the lines in a given string as an array

In this example, we take a string value in str, where the string is contains multiple lines, where the lines are separated by new line character. We shall split this string, and get the lines in an array linesArray. Each element in the resulting array is a line (string) from the original string.

main.swift

import Foundation

let str = "Hello World!\nApple is red.\nBanana is good."
let linesArray = str.components(separatedBy: "\n")
print(linesArray)

Output

Conclusion

In this Swift Tutorial, we have seen how to split a given multiline string into a string array of individual lines, with examples.
