**PadScaler** is a library for easy UI scaling between iPhone and iPad (11", 13", and future models). It automatically adapts interface element sizes for different screen sizes.

🚀 Installation

PadScaler can be installed using Swift Package Manager (SPM).

1. Installation via Swift Package Manager

Xcode (Recommended Method)
  1. Open File → Add Packages... in Xcode.
  2. Enter the repository URL:

`` https://github.com/quasaryy/PadScaler.git ``

  1. Select the version (Up to Next Major Version → 1.0.0).
  2. Click Add Package and attach PadScaler to your target.
SPM in Package.swift

If you are using Swift Package Manager manually, add the dependency in Package.swift:

dependencies: [
    .package(url: "https://github.com/quasaryy/PadScaler.git", from: "1.0.0")
]

Then import it into your code:

import PadScaler

📌 Usage

PadScaler provides convenient methods for adapting UI element sizes.

1. Scaling sizes (scaledSize)

Scales numeric values for iPad based on standard multipliers:

let scaledValue = 10.scaledSize

✅ Result:

  • 10 on iPhone
  • 16 on iPad 11"
  • 20 on iPad 13"

If you need to set custom multipliers:

let customScaled = 10.scaledSize(smallPadMultiplier: 1.5, largePadMultiplier: 2.3)

If only the large iPad multiplier is set, the small iPad multiplier will be automatically calculated:

let autoScaled = 10.scaledSize(largePadMultiplier: 2.3)

✅ Result:

  • 10 on iPhone
  • 1.839 (automatically calculated) on iPad 11"
  • 23 on iPad 13"

2. Adaptive sizes (adaptiveSize)

Allows specifying different values for iPhone, iPad 11", and iPad 13":

let adaptive = adaptiveSize(phone: 5, smallPad: 7.6, largePad: 8.7)

✅ Result:

  • 5 on iPhone
  • 7.6 on iPad 11"
  • 8.7 on iPad 13"

3. Using with SwiftUI

PadScaler works great with SwiftUI:

Text("Adaptive Text")
    .font(.system(size: 16.scaledSize))
    .padding(20.scaledSize)

🛠 Configuration

1. Global configuration (shared instance)

PadScaler.setSharedConfiguration(ScalingConfiguration(
    defaultSmallPadMultiplier: 1.5,
    defaultLargePadMultiplier: 2.2
))

Now scaledSize will use these multipliers by default.

2. Using a custom instance

If you need to use different configurations in different places, create a separate instance:

let customPadScaler = PadScaler.newInstance(ScalingConfiguration(
    defaultSmallPadMultiplier: 1.8,
    defaultLargePadMultiplier: 2.5
))
let scaled = customPadScaler.scaledSize(10)
