Installation

Simply follow standard SPM conventions:

Swift Package Manager

Manual Installation

• Add package(url: "https://github.com/roz0n/Veximoji.git", from: "2.0.0") to your application’s Package.swift file.

Via Xcode

1. Open your project within Xcode and select File > Swift Packages > Add Package Dependency from the status bar menu.
2. Paste the HTTPS Github link: https://github.com/roz0n/Veximoji.git and click Next.
3. You’ll be asked to define package options. Up to Next Major is a safe default which accepts any version up to the next major release, click Next to proceed.

Once the package finishes downloading, should now see it listed in the Project Navigator on the left-hand pane. Likewise, feel free to select the project file, and Veximoji should be listed under the Swift Packages tab. Xcode will also automatically add it to your main project target under the “Frameworks, Libraries, and Embedded Content” header.

CocoaPods

CocoaPods support is in the works.

API

The Veximoji API is very concise and well-documented. It organizes emoji flags into four distinct categories:

Category	Definition	Example
country	flags for countries with an ISO 3611-1 alpha-2 code	JP
subdivision	flags for subdivisions with an ISO 3611-2 code	GB-ENG
international	flags for exceptionally reserved ISO 3166-1 alpha-2 codes	EU or UN
unique	flags not related to individual countries or subdivisions	.pirate or "pirate"

Categories

Each of the above categories are available in array-form via publicly exposed short-hand variables:

typealias EmojiFlagCategory

• A typealias of Veximoji.FlagCategories, an enum representing the above categories.

EmojiFlagCountryCodes: [String]

• Computes and returns all supported ISO 3166-1 country codes.

EmojiFlagSubdivisionCodes: [String]

• Computes and returns all supported ISO 3166-2 subdivision codes.

EmojiFlagInternationalCodes: [String]

• Computes and returns all supported exceptionally reserved ISO 3166-1 codes.

In the event you would like to validate any of the above manually, validation methods are publicly exposed for your convenience.

validateISO3166_1(code:) -> Bool

• Returns a boolean indicating whether a given string is a supported ISO 3611 alpha-2 country code by checking whether or not it is contained within the CFLocaleCopyISOCountryCodes collection
• For more information on supported country codes visit the CFLocaleCopyISOCountryCodes page of the Apple Developer Documentation

validateISO3166_2(code:) -> Bool

• Returns a boolean indicating whether a given string is a valid ISO 3611-2 subdivision code
• Currently, only Great Britain’s subdivision codes are supported as they are the only subdivisions with iOS-supported emoji flags

validateExceptionalReservation(code:) -> Bool

• Returns a boolean indicating whether a given string is a valid ISO 3166-1 exceptionally reserved code.
