Swift 5

    func simple_scrollToBottom() {
        let textCount: Int = text.count
        guard textCount >= 1 else { return }
        scrollRangeToVisible(NSRange(location: textCount - 1, length: 1))
    }
}

// Usage
textView.simple_scrollToBottom()

Answer 2

Make a range, specifying encoding, to the last character, then scroll to that range Something other than utf8 might be appropriate depending on your content

let range = NSMakeRange(self.OutputTextView.text.lengthOfBytes(using: String.Encoding.utf8), 0);
self.OutputTextView.scrollRangeToVisible(range);

Answer 3

Try this if you have problem on iOS 7 or above. See this SO answer.

- (void)scrollTextViewToBottom:(UITextView *)textView {
    NSRange range = NSMakeRange(textView.text.length, 0);
    [textView scrollRangeToVisible:range];
    // an iOS bug, see https://stackoverflow.com/a/20989956/971070
    [textView setScrollEnabled:NO];
    [textView setScrollEnabled:YES];
}

This works for me! :D

CGPoint bottomOffset = CGPointMake(0, self.textView.contentSize.height - self.textView.bounds.size.height);
[self.description1 setContentOffset:bottomOffset animated:YES];
