Swift Sage-expert assistance for Swift developers

Example

A developer is unsure why their Swift code is not performing as expected. They input a snippet into Swift Sage, and it analyzes the code, pointing out logic errors and suggesting fixes with detailed explanations.

Scenario

A user writes a function to parse JSON data from a web API, but the app crashes. Swift Sage identifies that the `Decodable` struct is incorrectly defined and explains how to correct it by suggesting safe unwrapping techniques and improving error handling.

Example

A developer asks how to optimize a SwiftUI list view that lags when handling large datasets. Swift Sage suggests strategies like using `LazyVStack` and `@StateObject` to efficiently manage data and improve performance.

Scenario

A developer is creating a complex UI with dynamically loading images in a SwiftUI app. Swift Sage provides best practices for improving load times and maintaining UI responsiveness, such as utilizing background threads with `Task {}` for fetching data asynchronously.

Example

A beginner learning Swift requests a detailed explanation of closures, including examples and common use cases. Swift Sage provides an in-depth lesson covering the syntax, capturing values, and common pitfalls.

Scenario

A new Swift programmer wants to understand how to use closures in networking callbacks. Swift Sage not only explains how closures work but also provides step-by-step guidance on implementing them in URLSession tasks, emphasizing memory management with `[weak self]`.
