How work genmoji

Genmoji is a new feature introduced by Apple that allows users to create personalized emoji-like images, which can be used to express emotions, objects, and scenes in a more customized way. Unlike traditional emoji, which are standardized Unicode characters, Genmoji are unique rasterized bitmaps that cannot be described by a Unicode text character. They are handled using the NSAdaptiveImageGlyph API, which supports using Genmoji and other personalized images in applications.

Genmoji can be integrated into apps that support rich text. If your app already uses rich text views, enabling Genmoji could be as simple as enabling support for adaptive image glyphs. This feature is natively supported by rich text views, and system serialization frameworks have been updated to support it. Genmoji can be used in various contexts, such as blog posts, messages, and notifications, but they are not suitable for text-only items like email addresses or phone numbers.
