Question

I need to read and write data to/from a text file, but I haven\'t been able to figure out how.

I found this sample code in the Swift\'s iBook, but I still don\'t kno

You may find this tool useful to not only read from file in Swift but also parse your input: https://github.com/shoumikhin/StreamScanner

Just specify the file path and data delimiters like this:

import StreamScanner

if let input = NSFileHandle(forReadingAtPath: "/file/path")
{
    let scanner = StreamScanner(source: input, delimiters: NSCharacterSet(charactersInString: ":\n"))  //separate data by colons and newlines

    while let field: String = scanner.read()
    {
        //use field
    }
}

Hope, this helps.
