Emojica
A Swift framework for replacing iOS system emoji with custom emoji sets in UILabel and UITextView.
What is Emojica?
Emojica is a Swift framework that allows iOS developers to replace standard system emoji with custom emoji image sets in their apps. It solves the problem of limited emoji customization by enabling full control over emoji appearance in text views and labels, supporting real-time conversion and compatibility with all iOS 13 emoji.
iOS developers building apps that require custom emoji branding, themed emoji sets, or enhanced emoji presentation beyond the default system offerings.
Developers choose Emojica for its seamless integration with UIKit components, support for popular emoji sets like Twemoji, and safe fallback handling that ensures app stability even with incomplete image sets.
Overview
A Swift framework for using custom emoji in strings.
Use Cases
Best For
- Adding branded or themed emoji to iOS apps
- Replacing default iOS emoji with Twemoji or other custom sets
- Implementing real-time emoji conversion in chat or input fields
- Creating apps with unique emoji aesthetics for specific audiences
- Enhancing UILabel and UITextView with custom emoji support
- Building emoji-heavy applications like social or messaging platforms
Not Ideal For
- Apps targeting iOS versions below 13.0 due to untested compatibility and potential instability.
- Objective-C projects without Swift integration, as support requires source modifications and isn't officially provided.
- Cross-platform applications needing consistent custom emoji across iOS, Android, and web, since Emojica is iOS-only.
- Teams requiring zero-setup emoji customization, as some image sets like Twemoji need manual file renaming via a script.
Pros & Cons
Pros
Supports all iOS 13 emoji characters and sequences, ensuring compatibility with modern emoji standards without gaps.
Works with any custom emoji set like Twemoji or EmojiOne, and includes safe fallback to system emoji for missing images, preventing app crashes.
Integrates directly with UITextViewDelegate for live emoji replacement during typing, enhancing user experience in chat or input fields.
Allows converted emoji strings to be reverted to original representation, useful for data storage, editing, or backward compatibility.
Cons
Only tested on iOS 13+, with no guarantees for older versions, potentially excluding users on legacy devices or apps with broad version support.
Requires running a rename script for compatible sets like Twemoji and Noto Emoji, adding complexity and risk of file overwriting during integration.
Compatible sets like EmojiOne have missing code points (e.g., U+2640, U+2642), leading to gaps in emoji coverage unless fallbacks are used.
