This is how to load a rtf file

NSURL * url = [NSBundle.mainBundle URLForResource:@"example"
                                    withExtension:@"rtf"];
NSData * content = [NSData dataWithContentsOfURL:url];
NSError * e;
NSAttributedString * aText = [[NSAttributedString alloc]
                              initWithData:content
                              options:@{NSDocumentTypeDocumentAttribute: NSRTFTextDocumentType}
                              documentAttributes:NULL
                              error:&e];

self.textView.attributedText = aText;

  1. Drag your TextView control (I had to click 3 times until it said NSTextView) to your AppDelegate.m file underneath the first @interface line. Mine was @interface AppDelegate (). The reason for the three clicks is because by default when you drag a TextView control on a window, it creates 3 controls and it's only the inner, inner one that is set to NSTextView. The other controls deal with scrolling and screen clipping. Then, choose to create an outlet and name it something like txtRich or whatever you want. This created this entry for me in my case:
@property (unsafe_unretained) IBOutlet NSTextView *txtRich;
  1. Find a class method where you want to load the RTFD. I did mine in the AppDelegate.m under applicationDidFinishLaunching. Inside that, paste something like this:
NSBundle *myBundle = [NSBundle mainBundle];
NSString *sFile= [myBundle pathForResource:@"myrichfile" ofType:@"rtfd"];
[self.txtRich readRTFDFromFile:sFile];

You may be wondering where this mainBundle comes from, and if you have to declare it somewhere. The answer is no. It's freaking magic, created by default, just like the NSNotificationCenter defaultCenter variable. It refers to your own application bundle.

  1. Now, use TextEdit to create a file myrichfile.rtfd. Save it in your project folder. Drag it to your project window under the Supporting Files. When you get prompted, go with the defaults. This bundles it with your project in a Resources folder.

myTextView.attributedText =
[   NSAttributedString.alloc
    initWithFileURL:[ NSBundle.mainBundle URLForResource:@"filename" withExtension:@"rtf"  ]
    options:nil
    documentAttributes:nil
    error:nullptr
];

What you've done so far will get you the name of the file, you need to go one step further and actually read the contents of the file into an NSString, using something like:

NSError *err = nil;
NSString *fileContents = [NSString stringWithContentsOfFile:filePath 
                           encoding:NSUTF8StringEncoding
                           error:&err];
if (fileContents == nil) {
    NSLog("Error reading %@: %@", filePath, err);
} else {
    myTextView.text = fileContents;
}

That will work for plain text (assuming your file is in UTF8 encoding); you'll have to do something a lot fancier for RTF (UITextView doesn't know how to display RTF).

You may try with this:

NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
myTextView.text  = myText;
