Library for creating UIImage from Emoji.
- Designers like to use Emoji in the app interface, but the AppStore may reject the app if emojis are used as a prerendered images. [1]
From App Store Review Guidelines:
4.5.6 Apps may use Unicode characters that render as Apple emoji in their app and app metadata. Apple emoji may not be used on other platforms or embedded directly in your app binary.
To get around this limitation, you can generate Emoji in runtime using this library.
- You can use Emoji as text, but it's not always convenient. Sometimes you need to use emojis as an avatar placeholder or make emojis grayscale.

- Create more built-in image processings
- Find a way to get a high-quality images
To view the sample app open Emoji.workspace and run Example target.
You also can use SwiftUI preview canvas in Example/ContentView.swift` file.
