How to find the length of the shortest word in a string with Swift

Answer 1

import Foundation

func shortestWordLength(in text: String) -> Int {
    // Split on whitespace; filter removes empty strings
    let words = text
        .components(separatedBy: .whitespacesAndNewlines)
        .filter { !$0.isEmpty }

    // Return 0 if no words exist
    return words.map { $0.count }.min() ?? 0
}

func main() {
    let input = "Find the shortest word length in this string"
    let result = shortestWordLength(in: input)

    if result == 0 {
        print("No words found.")
    } else {
        print("Length of the shortest word: \(result)")
    }
}

main()



/*
run:

Length of the shortest word: 2
