How to add text to the last line of a text file

[iT-Boyer]

Consulting chatgpt gives the following tips, but the append method is not found in pathkit：

import PathKit

let path = Path("/path/to/file.txt")
let text = "Hello, PathKit!"

do {
    try path.append(text) //add text to the last line of a text file
} catch let error {
    print(error)
}
