Question

How to find the second largest word in a string with Swift

Answer 1

import Foundation

func secondLargestWord(in str: String) -> String? {
    let words = str.components(separatedBy: CharacterSet.whitespacesAndNewlines)
    
    let sortedWords = words.sorted { $0.count > $1.count }
    
    guard sortedWords.count > 1 else {
        return nil
    }
    
    return sortedWords[1]
}

let str = "Swift is a powerful programming language for iOS, iPadOS, macOS"

if let secondLargest = secondLargestWord(in: str) {
    print("The second largest word is: \(secondLargest)")
} else {
    print("There are not enough words in the string.")
}




/*
