Read different sections of a string

I store some files in file manager and I need three data string in their name that I can do the necessary modification, they data I need are two ids and one timestamp, something like that

"hdh3npHvjjkdfydlz-jfoabcotmdbnadp-1657155181" 

I want to read each of them separately, those three data is separated by one – and the number of the characters may be not the same for different files. Can anyone help me to do that?

>Solution :

If I understand you correctly, you want to extract each piece of info from the string using a hyphen as a delimiter? If so, you could use:

import UIKit

let myString = "hdh3npHvjjkdfydlz-jfoabcotmdbnadp-1657155181"
let components = myString.components(separatedBy: "-")

for c in components {
    print(c)
}

Or alternatively:

let items = myString.split(separator: "-")

for i in items {
    print(i)
}

Either one will separate the string into individual pieces using the hyphen as a delimiter.
