Flag Kit
A collection of beautiful flag icons in PNG and SVG formats with framework support for Apple platforms.
What is Flag Kit?
FlagKit is an open-source library that provides a collection of beautifully designed flag icons for use in apps and on the web. It solves the problem of sourcing and integrating high-quality, consistent flag assets by offering over 250 flags in PNG and SVG formats, along with native framework support for Apple platforms.
Mobile and web developers, particularly those building iOS, macOS, or tvOS applications that require country or region flag displays, such as in localization features, user profiles, or geographic content.
Developers choose FlagKit for its professionally designed icons, easy integration via popular package managers, and the convenience of having styled and unstyled flag variations readily available, saving time compared to manually creating or sourcing flag assets.
Overview
Beautiful flag icons for usage in apps and on the web.
Use Cases
Best For
- Displaying country flags in user profile settings
- Building localization or region selection interfaces
- Adding geographic indicators to maps or location-based apps
- Creating educational or travel-related applications
- Enhancing UI with styled flag icons for badges or avatars
- Quickly prototyping apps that require international flag assets
Not Ideal For
- Cross-platform projects targeting Android or web without Apple ecosystem integration
- Applications requiring real-time flag updates for geopolitical changes or new country additions
- Teams needing deep customization like custom color schemes or animations beyond provided shapes
- Projects with strict bundle size constraints where including all 250+ flags is prohibitive
Pros & Cons
Pros
Provides over 250 professionally designed flag icons in PNG and SVG formats, ensuring consistency and beauty across applications, as highlighted in the README's emphasis on simplicity and beauty.
Includes a dedicated framework and Asset Catalog for easy use on iOS, macOS, and tvOS, with support for Swift Package Manager, Carthage, and CocoaPods, making installation straightforward per the installation section.
Offers flags in various shapes like circles, squares, and rounded corners, in addition to original rectangular flags, allowing for quick customization, as demonstrated in the sample project mentioned in the README.
Contains flags for over 250 countries and regions, supporting a wide range of locales for international applications, which is a key feature listed in the description.
Cons
The README explicitly states that styling is not supported on macOS, restricting UI consistency and flexibility across Apple platforms, which is a notable omission for developers targeting macOS.
While PNG/SVG files are available, the framework and Asset Catalog are tailored for Apple ecosystems, making it less suitable for cross-platform projects that don't use iOS, macOS, or tvOS.
Flags are provided as static files without an update mechanism, so developers must manually handle changes if flags evolve due to political or regional updates, which isn't addressed in the documentation.
