Read a text file with swift

There are several posts already. But none helps me in my task. Sometimes error message appears: "The file "Text.strings" couldn't be opened using text encoding Unicode (UTF-8)." Sometimes the text is shown in strange format. Why?

import Foundation



func printLine() -> String {

    let filename = "Text"

    var text: String

    var myCounter: Int

    

    guard let file = Bundle.main.url(forResource: filename, withExtension: "strings")

    else {

        fatalError("Couldn't find \(filename) in main bundle.")

    }



    do {

        let contents = try String(contentsOf: file, encoding: String.Encoding.utf8 )

        let lines = contents.split(separator:"\n")

        print(contents)

        print(lines)

        myCounter = lines.count

        print(myCounter)

        text = String(myCounter)

        } catch {

            return (error.localizedDescription)

        }

        return text



}

This is the content of the text file:

"Text 1";
"Text 2";
"Text 3";
