Question

How to remove text between parentheses in a string using Swift

Answer 1

import Foundation

func cleanString(_ text: String) -> String {
    // Step 1: Remove parentheses and their content (non-greedy)
    let withoutParen = text.replacingOccurrences(
        of: "\\([^)]*\\)",
        with: "",
        options: .regularExpression
    )
    
    // Step 2: Collapse multiple spaces into one
    let collapsedSpaces = withoutParen.replacingOccurrences(
        of: "\\s+",
        with: " ",
        options: .regularExpression
    )
    
    // Step 3: Trim leading/trailing spaces
    return collapsedSpaces.trimmingCharacters(in: .whitespacesAndNewlines)
}

let original = "Hello (remove this) from the future (and this too)"
let cleaned = cleanString(original)

print("Original: \(original)")
print("Cleaned : \(cleaned)")



/*
run:

Original: Hello (remove this) from the future (and this too)
Cleaned : Hello from the future

*/
