8/10 High

Query: “What are the most common pain points with Swift for developers in 2025?”4/4/2026

The author complains about their PM's decision to adopt SwiftUI too casually, arguing that it is ill-suited for rewriting a seven-year-old app. Migration should be incremental, not a big-bang rewrite. SwiftUI's weak spots can be avoided—for example, by keeping UIKit navigation and migrating only the view layer.
