I just couldn't find utf-8 encoding for character like following:

enter image description here

I think that it is quite possible to create this in code, as a composed character from two dashes: / and \, but I do not know what characters to compose.

Possibly U+2039.

print("\u{2039}") // ‹

Or U+276E.

print("\u{276E}") // ❮

I'm not certain if this will work for a navigation item, but you could make use of NSAttributedString to have string with different sizes of the substrings within it. This is described in detail in this great answer:

As an example for your case:

let myAttributeBack = [ NSFontAttributeName: UIFont(name: "HelveticaNeue-UltraLight", size: 30.0)!]
let attrString = NSMutableAttributedString(string: "\u{276E} ", attributes: myAttributeBack)

let myAttributeText = [ NSFontAttributeName: UIFont(name: "HelveticaNeue-UltraLight", size: 15.0)!]
let backString = NSAttributedString(string: "back", attributes: myAttributeText)

attrString.appendAttributedString(backString)

myLabel.attributedText = attrString

However, as you write below, perhaps it's not possible to use attributed strings for title of a navigation bar item. Then I'd assume that the navigation bar example you showed above simply contains an image with the back bracket and a string "back" for the title text.

  • the first one is correct, but too small. Can I increase the size somehow? I need to assign it this way: `navigationItem.leftBarButtonItem?.title = "\u{2039}Back"`. `attributedTitle` doesn't work. – Bartłomiej Semańczyk Jan 07 '16 at 11:10
  • Hmm you should be able to increase the size of only parts of a text field (attributed strings). however I'm not sure it will work with the navigation button. 1 min (see also if possibly U+276E can, added into answer). In your example above, it looks as if the "<" is of quite larger font than the text. – dfrib Jan 07 '16 at 11:17
  • Is there a third one slightly bigger than the previous one?:) – Bartłomiej Semańczyk Jan 07 '16 at 11:19
  • I haven't been able to find one, but I think you want to use one of the two above and use `NSAttributedString`. Trying something out, a few mins :) – dfrib Jan 07 '16 at 11:31
  • I think this is impossible to assign `NSAttributedString` to the `title` of `leftBarButtonItem`. – Bartłomiej Semańczyk Jan 07 '16 at 11:34
  • @BartłomiejSemańczyk I see, then it's gonna be tricky... Perhaps the above example is using an image + text? – dfrib Jan 07 '16 at 11:38
  • Alternatively create your own custom UILabel that the navigation bar makes use of. The UILabel can make use of attributed strings. – dfrib Jan 07 '16 at 12:04

Maybe U+003C

print("\u{003C}") // <

Is it this:

The code is U+276C. see https://en.wiktionary.org/wiki/%E3%80%88
