What is a monospace font in iOS?

I want a monospace font for my UILabel in my iOS application.

Unfortunately, I could not find one. Even "American Typewriter" was not actually monospaced. What is a monospace font available in XCode?

iOS mono-spaced fonts

Courier  
Courier-Bold  
Courier-BoldOblique

iosfonts.com maintain a list of all iOS fonts.

This webpage detects your installed system fonts and returns a fairly comprehensive list.

Looking at an old listing of fonts shipped with iOS I see several one monospace fonts.

(eg. Andale Mono, Monaco, Courier New)

For 2018 it's only Menlo and Courier.

If your intent is to display numbers and you don't care about the specific font used, you can do this:

UIFont.monospacedDigitSystemFontOfSize(
    UIFont.systemFontSize(),
    weight: UIFontWeightRegular)

Adobe just released a nice monospaced font Source Code Pro in both TTF and OTF formats. It's licensed with the Open Font License so it is available for free use within applications, including commercial applications. You will need to add the font file as a resource in Xcode, by setting the UIAppFonts key in the info.plist to point to the SourceCodeProRegular.ttf file.

Now in your code you can set, for example:

    self.textView.font = [UIFont fontWithName:@"Source Code Pro" size:14];

Expanding upon @reggie-pinkham's answer, I built this JS Bin for folks to use as a live test page; to save future reader's some time, here's a few screen shots using iOS Simulator on Mavericks:

iPad Air, iOS 8.1

iPhone 6 plus, iOS 8.1

As of iOS 13, San Francisco (SF) Mono is available. Couldn't find a way to set this in interface builder, but by code it's:

let font = UIFont.monospacedSystemFont(ofSize: 17.0, weight: .regular)

If you're looking for a monospace font for numbers, then try "Helvetica Neue".

A list of built-in fonts available on iOS: http://iosfonts.com. Courier and Menlo seem to be the only monospace fonts in there.

SwiftUI

You can use Font's instance method monospacedDigit

Text("0123456789")
    .foregroundColor(.white)
    .font(Font.custom("San Francisco", size: 20).monospacedDigit())

You can access system fonts in monospaced with the following Font factory method:

static func system(Font.TextStyle, design: Font.Design) -> Font

Example:

let monospacedBody = Font.system(.body, .monospaced)

Other usage:

let serifTitle = Font.system(.title, .serif)

In the meantime there is a good Monospace font available from Apple, that can be downloaded here: Apple SFUI Here is how to add the fonts to Xcode: Add fonts to xcode
