How to check if a string starts with a substring from an array of substrings in Swift

Answer 1

import Foundation

func startsWithAny(string: String, substrings: [String]) -> Bool {
    for substring in substrings {
        // Use hasPrefix to check if the string starts with the substring
        if string.hasPrefix(substring) {
            return true
        }
    }
    return false // Return false if no substring matches
}

let string = "abcdefg"
let substrings = ["xy", "poq", "mnop", "abc", "rsuvw"]

// Check if the string starts with any substring from the array
if startsWithAny(string: string, substrings: substrings) {
    print("The string starts with a substring from the array.")
} else {
    print("The string does not start with any substring from the array.")
}



/*

The string starts with a substring from the array.
