How to Split A String Into an Array In Swift?

9 minutes read

To split a string into an array in Swift, you can use the components(separatedBy:) method of the String class. This method takes a delimiter as a parameter and returns an array containing the substrings that are separated by the delimiter in the original string. For example, if you have a string "Hello, World!" and you want to split it by the comma delimiter, you can use the following code:

1
2
3
let str = "Hello, World!"
let delimiter = ","
let array = str.components(separatedBy: delimiter)


After running this code, the array will contain two elements - "Hello" and " World!". You can then access and manipulate these elements as needed.

What is the NSMakeRangeFromString function in Swift and how can it be used to split a string into an array?

In Swift, there is no built-in function called NSMakeRangeFromString. However, you can achieve the same functionality by using the range(of: options: range: locale:) method provided by the String class.


Here is an example of how you can split a string into an array using the range(of: options: range: locale:) method:

1
2
3
4
let inputString = "Hello, Swift, World"
let delimiter = ","
let stringArray = inputString.components(separatedBy: delimiter)
print(stringArray) // Output: ["Hello", " Swift", " World"]


In this example, we first define the input string and the delimiter character ("," in this case). We then call the components(separatedBy:) method on the inputString object, passing in the delimiter as a parameter. This method splits the inputString into an array of substrings based on the specified delimiter.


Alternatively, you can use the components(separatedBy:) method on the String class to split a string into an array based on a delimiter.


How to split a string into an array by special characters in Swift?

In Swift, you can split a string into an array by special characters using the components(separatedBy:) method. Here's an example of how to split a string by a special character, such as a comma:

1
2
3
4
5
6
let string = "apple,banana,orange"

// Split the string by comma and store the results in an array
let array = string.components(separatedBy: ",")

print(array) // Output: ["apple", "banana", "orange"]


In this example, the components(separatedBy:) method is used to split the string "apple,banana,orange" by the comma character. The resulting array contains three elements: "apple", "banana", and "orange". You can replace the comma , with any other special character to split the string by that character.


How to split a string into an array by a regular expression pattern in Swift?

You can split a string into an array using the components(separatedBy:) method in Swift with a regular expression pattern as the separator. Here's how you can do it:

1
2
3
4
5
6
7
8
import Foundation

let string = "Hello, World! This is a sample text."
let pattern = "[,.! ]+" // Regular expression pattern to split by commas, periods, exclamation marks, or spaces

let components = string.components(separatedBy: NSRegularExpression(pattern: pattern, options: []))

print(components)


In this example, the components(separatedBy:) method is used with an NSRegularExpression object created with the specified regular expression pattern [,.! ]+. This pattern matches one or more occurrences of commas, periods, exclamation marks, or spaces. The resulting array components will contain the substrings of string split by the specified pattern.


Make sure to import Foundation at the beginning of your file in order to use NSRegularExpression.
