Font	Best For
OpenDyslexic	Readers with dyslexia
Atkinson Hyperlegible	Users with low vision
Lexend	Improving reading fluency
Inter	UI elements and screen readability
Open Sans	General-purpose readable content
Inconsolata	Code and monospace content

Quick Start

SwiftUI

import AccessibleFonts

struct ContentView: View {
    var body: some View {
        VStack {
            Text("Hello, World!")
                .font(.accessible(.openDyslexic, size: 17))
            
            Text("Bold Text")
                .accessibleFont(.lexend, size: 24, weight: .bold)
        }
    }
}

UIKit

import AccessibleFonts

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let label = UILabel()
        label.font = UIFont.accessible(.atkinsonHyperlegible, size: 17)
        label.text = "Easy to read text"
    }
}

AppKit

import AccessibleFonts

class ViewController: NSViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let textField = NSTextField()
        textField.font = NSFont.accessible(.inter, size: 17)
    }
}

Features

Automatic Font Registration

Fonts are automatically registered when you first use them. No setup required!

// Just use the font - registration happens automatically
Text("Hello").font(.accessible(.lexend, size: 17))

If you prefer explicit control:

// Register all fonts at app startup
try AccessibleFonts.registerAll()

// Or register specific families
try AccessibleFonts.register(.openDyslexic)

Dynamic Type Support

All APIs support Dynamic Type on iOS, iPadOS, tvOS, and watchOS:

// SwiftUI - automatically scales with text style
Text("Headline")
    .font(.accessible(.lexend, size: 28, relativeTo: .headline))

// UIKit - uses UIFontMetrics for scaling
let font = UIFont.accessible(.lexend, size: 17, textStyle: .body)

Weight and Style Variants

// Different weights
Text("Thin").font(.accessible(.inter, size: 17, weight: .thin))
Text("Regular").font(.accessible(.inter, size: 17, weight: .regular))
Text("Bold").font(.accessible(.inter, size: 17, weight: .bold))
Text("Black").font(.accessible(.inter, size: 17, weight: .black))

// Italic (where available)
Text("Italic").font(.accessibleItalic(.inter, size: 17))

Fallback Handling

If a font can't be loaded, the API gracefully falls back to a system font:

• Debug builds: Triggers an assertion failure so you can fix the issue
• Release builds: Silently uses a matching system font
