How to read a text file while developing an ios app using xcode

Question

I'm now developing an iOS app using xcode(Swift). I want to import the data which is stored in a text file, and show the words from the text file on the screen. How can I import an existing text file into the project? Should I install anything? How can I read the text file and store the words in an array?

You can read a file easily in iOS. Follow these steps:

Step 1: Add a File into project

Step 2: Reading a file

EDIT

Swift:

    let filePath = Bundle.main.path(forResource: "File", ofType: "txt");
    let URL = NSURL.fileURL(withPath: filePath!)

    do {
        let string = try String.init(contentsOf: URL)

        // use string here
        print("read: " + string)
    } catch  {
        print(error);
    }

Objective-C:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"file" ofType:@"txt"];
NSURL *url = [NSURL fileURLWithPath: filePath];
NSString *string = [[NSString alloc] initWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];

Thanks!
