Question

How to create an array containing a range of characters in Swift

Answer 1

import Foundation

func createCharRangeArray(startChar: Character, endChar: Character) -> [Character] {
    if endChar < startChar {
        return [] // Return an empty array for invalid input
    }

    var charArray: [Character] = []
    if let startValue = startChar.asciiValue, let endValue = endChar.asciiValue {
        for charValue in startValue...endValue {
            let scalar = UnicodeScalar(charValue) 
            charArray.append(Character(scalar))
        }
    }
    
    return charArray
}

let charRange = createCharRangeArray(startChar: "b", endChar: "k")

print(charRange)



/*
run:

["b", "c", "d", "e", "f", "g", "h", "i", "j", "k"]
