parse out a number in a Specific position from an integer in SWIFT

Hello,

How i can get any number from an integer in any position

example: var number = 74401

how do i get the number 4 or any number i want, ?

It depends, are you looking for the index of the number of 4, or are you looking to return any number in the thousands position? (or the hundreds position, you have two 4s)

Try this: It breaks a number into an array of characters, then converts the character back to an integer to sum it up. Put this into a playground:

var number = 74401
var sum = 0
var charArray = Array(String(number))

for char in charArray {

    var digit = String(char).toInt()

    sum += digit!
}

sum

in fact i want to sum all the numbers

74401 => 7+4+4+0+1

so i need to get a single digit in each loop iteration

Thank u
