iOS Developer-iOS development code assistance

Example

Generate clean, concise Swift code for common patterns like singleton design, delegation, closures, or concurrency handling using GCD or async/await.

Scenario

A developer needs to implement a thread-safe singleton pattern for a service manager in an app. iOS Developer provides a ready-made Swift implementation with GCD dispatching to handle concurrency.

Example

Provide code samples for complex UI layouts in SwiftUI or UIKit, like dynamic forms, custom controls, or animations.

Scenario

A developer working with SwiftUI needs to implement a complex dynamic list with multiple item types and actions. iOS Developer generates a sample List view with dynamic rows using `ForEach`, including custom views for each item type and interactive elements.

Example

Help set up Core Data models, fetch requests, and data persistence logic in Swift apps.

Scenario

A developer is adding a local persistence layer to an iOS app. iOS Developer provides the code for setting up a Core Data stack, defining entities, and performing CRUD operations on the managed object context.

Example

Generate sample code for performing network requests, handling JSON responses, error handling, and caching strategies.

Scenario

A developer needs to integrate REST APIs in their app and handle authentication tokens and error states. iOS Developer provides sample code for making GET/POST requests using `URLSession`, handling authentication headers, decoding JSON with `Codable`, and retry logic.

Example

Offer tips on reducing memory usage, improving app launch times, and optimizing rendering performance, with code adjustments for view hierarchy or lazy loading.

Scenario

A developer is working on an app with a sluggish performance during UI transitions. iOS Developer suggests reducing view hierarchy depth, using lazy loading for images, and provides code to batch update UI elements to minimize CPU usage.

Example

Guide developers on implementing architectural patterns like MVC, MVVM, and VIPER in Swift projects.

Scenario

A team is migrating their project to an MVVM architecture and needs to decouple business logic from views. iOS Developer offers a clear separation of model, view, and view model layers, with examples of data binding and event handling in SwiftUI.

Example

Generate unit test cases for `XCTest` or integration tests for API calls and view rendering.

Scenario

A developer wants to write unit tests for a network service class using dependency injection. iOS Developer provides sample `XCTest` code for mocking URLSession and verifying API responses.
