Why does IF >< function doesn't work

Hi,

Can someone please help me with this issue, I am quite new in this, I am using Swift for 2 days now and I am facing an weird thing...If anyone can please explain me what is wrong in this code...the IF >< function doesn't work as it doesn't recognise the higher number...I will attach the picture here and also the code if you guys can please explain what I am doing wrong...I am trying to fix this for couple of hours and I get stuck here....Thanks in advance!

import UIKit

let leftNumber = ["2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "02", "03", "04", "05", "06", "07", "08", "09", "010", "011", "012", "013", "014", "002", "003", "004", "005", "006", "007", "008", "009", "0010", "0011", "0012", "0013", "0014", "0002", "0003", "0004", "0005", "0006", "0007", "0008", "0009", "00010", "00011", "00012", "00013", "00014"]

let randomName = leftNumber.randomElement()!

let rightNumber = ["2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "02", "03", "04", "05", "06", "07", "08", "09", "010", "011", "012", "013", "014", "002", "003", "004", "005", "006", "007", "008", "009", "0010", "0011", "0012", "0013", "0014", "0002", "0003", "0004", "0005", "0006", "0007", "0008", "0009", "00010", "00011", "00012", "00013", "00014"]

let randomName2 = rightNumber.randomElement()!

let trimmedString = randomName.replacingOccurrences(of: "^0+", with: "", options: .regularExpression)

let trimmedString2 = randomName2.replacingOccurrences(of: "^0+", with: "", options: .regularExpression)

if trimmedString > trimmedString2 {

print ("Number 1")

}

else if trimmedString2 > trimmedString {

print ("Number 2")

}

You're comparing Strings, not numbers, and "3" comes after "13", at least in Swift's default String sorting.

Thank you very much for the fast response!!

So can you please give me an idea how to make this work? How can I make random numbers based on the numbers I have there?

I suggest you either look up how to customize String comparison or how to convert Strings to numbers.

Thanks, will go back to practice now, it makes sense for me now!
