Question 1

How do I use Emojica with Twemoji in my iOS app?

Accepted Answer

Download the Twemoji image set, run the included rename.sh script to format file names, then configure Emojica with the image set and integrate it into your UILabel or UITextView using the convert method. This ensures proper emoji rendering without manual image handling.

Question 2

Does Emojica work on iOS 12 or lower?

Accepted Answer

Emojica is only tested on iOS 13 and above, and the README states lower versions haven't been verified. While it might run, compatibility isn't guaranteed, so it's risky for apps supporting older iOS versions without extensive testing.

Question 3

Emojica vs building custom emoji support from scratch?

Accepted Answer

Emojica saves development time by handling emoji parsing, conversion, and fallbacks automatically, whereas building from scratch requires implementing Unicode sequences and image rendering manually. However, for simple needs or full control, a custom solution might be more lightweight.

Question 4

How to enable real-time emoji conversion in a UITextView?

Accepted Answer

Implement the textViewDidChange delegate method and call emojica.textViewDidChange(textView) to convert emoji live as the user types. This updates the text view's attributed text immediately, providing seamless visual feedback.

Question 5

Can Emojica be used with SwiftUI?

Accepted Answer

Emojica is designed for UIKit components like UILabel and UITextView. For SwiftUI, you'd need to wrap it in a UIViewRepresentable, but this isn't documented and could require extra effort for integration and performance tuning.

Question 6

What happens if my custom emoji set is incomplete?

Accepted Answer

Emojica uses the original system emoji as fallback for missing images, so your app remains stable and functional. This safety feature prevents crashes but may result in mixed emoji styles if the set has gaps.
