How do I set transparency with FlatUIColors in Swift?

Use the optional alpha parameter in the color functions, like FlatUIColors.emerald(0.25) for 25% opacity. This is directly supported by the library, as shown in the code examples, with alpha as a CGFloat between 0 and 1.

Is FlatUIColors compatible with SwiftUI?

FlatUIColors returns OSColor objects, which can be used in SwiftUI by converting to Color or integrating with UIKit/AppKit views. However, it's primarily designed for UIKit/AppKit, so direct SwiftUI usage may require extra steps.

Can I add my own colors to FlatUIColors?

No, FlatUIColors does not support adding custom colors as it's a static library with predefined colors. You would need to define additional colors separately in your project or fork the repository.

FlatUIColors vs. UIColor extension for custom colors: which is better?

FlatUIColors is better for quick access to standardized Flat UI colors, ensuring design consistency. For custom or diverse color needs, a UIColor extension offers more flexibility but requires manual setup and maintenance.

How to install FlatUIColors without CocoaPods?

The README only provides CocoaPods installation instructions. For other methods, you might need to manually add the source files or check if the library supports Swift Package Manager, which isn't mentioned, potentially limiting setup options.

Does FlatUIColors support dark mode in iOS?

No, FlatUIColors provides static colors without built-in support for dark mode variants. Developers must handle color adaptations for dark mode manually using iOS's trait collections or additional code.

What is FlatUIColors?

FlatUIColors is a Swift library that provides a collection of predefined colors from the Flat UI palette for iOS and macOS development. It solves the problem of manually defining and maintaining consistent Flat design colors in Swift projects by offering easy-to-use static methods that return platform-appropriate color objects.

Target Audience

iOS and macOS developers building applications with a Flat UI design aesthetic who want quick access to standardized colors.

Value Proposition

Developers choose FlatUIColors for its simplicity, platform-awareness, and time-saving convenience over manually defining Flat UI colors, ensuring design consistency with minimal code.

Overview

Flat UI color palette helpers written in Swift.

Use Cases

Best For

Adding Flat UI colors to iOS apps with Swift
Ensuring color consistency in macOS applications
Quick prototyping with predefined design system colors
Avoiding manual color hex code management
Building apps following Flat design principles
Supporting both iOS and macOS with a single color library

Not Ideal For

Projects requiring dynamic color theming or semantic color systems beyond Flat UI
Apps built with cross-platform frameworks like Flutter or React Native that need ecosystem-agnostic color libraries
Teams preferring Swift Package Manager over CocoaPods for dependency management
Design systems needing built-in dark mode variants or accessibility-focused color adjustments

Pros & Cons

Pros

Predefined Flat Palette

Includes over 40 named colors from the Flat UI design system, such as turquoise and sunflower, eliminating manual hex code definitions as listed in the README.

Platform-Aware Implementation

Uses OSColor typealias to automatically return UIColor for iOS and NSColor for macOS, ensuring cross-platform compatibility shown in the usage examples.

Alpha Transparency Support

Offers an optional alpha parameter in color functions, allowing easy transparency adjustments without extra code, as demonstrated with FlatUIColors.emerald(0.25).

Clean Static API

Colors are accessed via static methods on the FlatUIColors struct, providing a type-safe and intuitive interface for developers, per the key features.

Cons

Limited to Flat UI

Only supports the Flat UI color palette, making it unsuitable for projects requiring other design systems like Material Design or custom color schemes.

Static Color Definitions

Colors are hardcoded and cannot be easily extended or customized, restricting flexibility for advanced theming or color manipulation.

Dependency on CocoaPods

Installation requires CocoaPods as stated in the README, which may not align with projects using alternative package managers like Swift Package Manager.
