What are the font attributes of the text in prefersLargeTitles property?

Question

I'm trying to re-create the look of the prefersLargeTitles property. To that end, I was wondering if anyone can tell me the font and font size used for this property?

The reason why I'm trying to re-create this on my own is that when I hide the navigation bar in my view controller, the prefersLargeTitles property becomes automatically disabled and hidden. So the goal is to re-create this property as a custom UILabel instead.

TL:DR

Font	Color
SFUI-Bold 34.00pt	labelColor

You can check using the Debug View Hierarchy.

Here's all the properties:

Object

Class name	Address
UILabel	0x13680d3b0

Label

Text	Text	Lines	Behavior
Title	White:0 Alpha:1 (labelColor)	1	Enabled On
Plain Text	.SFUI-Bold 34.00pt		Highlighted off
	Aligned Natural

Baseline	Line Break	Min Font Scale
Align Baselines	Truncate Tail	0

Highlighted	Shadow	Shadow Offset
nil color	nil color	w 0 h -1

View

Layer	Layer Class	Content Mode	Tag	Interaction
<_UILabelLayer: 0x600003cae350>	_UILabelLayer	Left	0	User Interaction Enabled Off, Multiple Touch Off

Alpha	Background	Tint
1	White:0 Alpha:0 (clearColor)	R:0 G:0.48 B:1 A:1 (systemBlueColor)

Drawing
Opaque On
Hidden Off
Clears Graphics Context On
Clip To Bounds Off
Autoresize Subviews On

Accessibility (Is Accessibility Element, Not Focused)

Value	Traits	Elements	Description	Hint	Identifier	Actions
null	Header	null	Title	null	null	null

Answer 2

You can also get the values from the Typography section of the Human Interface Guidelines as they can vary from 31pt to 60pt depending on the user's chosen font size with Dynamic Type. There are separate tables for the base sizes:

and the accessibility sizes:

If you want to implement as a custom label for whatever reason, you can just let dynamic type do that for you rather than specifying exact point sizes as well:

mylabel.font = UIFont.preferredFont(forTextStyle: .largeTitle)
