SwiftUI Developers Replace Deprecated APIs With Alternatives
An expert developer warns iOS/SwiftUI engineers about common mistakes LLMs produce when generating Swift code, citing tools like Claude, Codex, and Gemini. The article lists deprecated APIs and idioms—such as foregroundColor(), cornerRadius(), NavigationView, and DispatchQueue.main.async—and recommends modern replacements like foregroundStyle(), NavigationStack, @Observable, and ImageRenderer to improve accessibility, concurrency, and performance on iOS 18+.
Key Points
- 1Replace deprecated SwiftUI APIs (foregroundColor, cornerRadius, NavigationView) with modern equivalents like foregroundStyle and NavigationStack.
- 2Avoid LLM-generated inefficiencies, deprecated usage, and hallucinated APIs to ensure accessibility and concurrency correctness.
- 3Adopt @Observable, Dynamic Type, ImageRenderer, and buttons for VoiceOver and better runtime performance.
Scoring Rationale
Practical, actionable guidance for SwiftUI and AI-assisted coding, with strong applicability but limited novelty and single-source observation.
