How to Replace multiple Spaces with a Single Space in String in Swift ?

Answer

To replace multiple spaces with a single space in Swift, you can use regular expressions with the replacingOccurrences method of the String class.

✐ Examples

1 Replace Multiple Spaces with a Single Space in a String

In this example,

We create a string named str with a string value containing multiple spaces.
We create a regular expression pattern \s+ to match one or more whitespace characters.
We use the replacingOccurrences method of the string object str to replace all occurrences of the pattern with a single space.
Finally, we print the modified string to standard output.

Swift Program

import Foundation

let str = "Hello   World    from    Swift"
let modifiedStr = str.replacingOccurrences(of: "\\s+", with: " ", options: .regularExpression)
print("Modified string: \(modifiedStr)")

Output

Modified string: Hello World from Swift

2 Replace Multiple Spaces with a Single Space in Another String

In this example,

We create another string named str1 with a string value containing multiple spaces.
We create a regular expression pattern \s+ to match one or more whitespace characters.
We use the replacingOccurrences method of the string object str1 to replace all occurrences of the pattern with a single space.
Finally, we print the modified string to standard output.

Swift Program

import Foundation

let str1 = "Swift    is   a    powerful  language"
let modifiedStr1 = str1.replacingOccurrences(of: "\\s+", with: " ", options: .regularExpression)
print("Modified string: \(modifiedStr1)")

Output

Modified string: Swift is a powerful language
