Answer 1

You may try with this:

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

Answer 2

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).
