Draw Animated Text Effects With SwiftUI TextRenderer

This article explains how to use SwiftUI's TextRenderer API to draw custom animated text effects while preserving text features like Dynamic Type, localization, and accessibility. It covers creating a minimal renderer, attaching it with the textRenderer modifier, and using custom TextAttribute to mark specific text ranges for effects. Examples include drawing highlights behind marked runs, with code snippets targeting iOS 18, iPadOS 18, and macOS 15+. The article emphasizes keeping text as real SwiftUI text rather than converting to images.
