How to load a string from a file in your bundle

Paul Hudson       @twostraws

If you have an important text file built into your app bundle that want to load it at runtime fact, String has an initializer just for this purpose. It’s called contentsOfFile, and here it is in action:

if let filepath = Bundle.main.path(forResource: "example", ofType: "txt") {
    do {
        let contents = try String(contentsOfFile: filepath)
        print(contents)
    } catch {
        // contents could not be loaded
    }
} else {
    // example.txt not found!
}

That code loads a file called example.txt into a string called contents.
