SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This reference provides a cohesive blueprint for implementing a Swift-based HTTP networking layer, covering endpoint definitions, request construction, error handling, and dependency injection.

Core Features & Use Cases

TargetType protocol, HTTPTask enum, ParameterEncoding, and ValidationType definitions that standardize API interaction.
HTTPClientProtocol and HTTPError for robust, testable HTTP communication and error reporting.
Real-world examples (e.g., THORChainAPI and TronAPI) demonstrating multi-endpoint APIs, mixed HTTPTask variants, and simple caching patterns.

Quick Start

Define at least one TargetType endpoint, wire it into a concrete HTTPClient, and call a service to perform a request.

FAQPage Schema

How do I build a structured URLSession HTTP networking layer in Swift?▼

You build a structured Swift HTTP networking layer by defining a TargetType protocol for endpoints, an HTTPTask enum for request parameters, and an HTTPClientProtocol to standardize URLSession API interactions. This provides a cohesive blueprint for structured API access.

How does dependency injection work with a Swift API client?▼

Dependency injection for a Swift API client is handled by defining an HTTPClientProtocol that abstracts request execution. You inject this protocol into your app features, allowing multiple services to use the same HTTP client while remaining testable and decoupled.

What's the best way to handle API errors in a Swift HTTP client?▼

The best way to handle Swift HTTP client errors is to implement a dedicated HTTPError type alongside a ValidationType definition. This standardizes error reporting and validates responses before processing, ensuring robust communication across your app's features.

Can I define multiple API endpoints for different blockchain networks in Swift?▼

Yes, you can define multiple endpoints for different networks in Swift. The reference includes real-world examples like THORChainAPI and TronAPI, demonstrating how to manage multi-endpoint APIs with mixed HTTPTask variants and simple caching patterns.

How do I standardize parameter encoding and HTTP methods for iOS API requests?▼

You standardize iOS API parameter encoding and HTTP methods by implementing ParameterEncoding and HTTPMethod definitions. These standardize how request parameters are encoded and sent via URLSession, ensuring consistent API interaction across your application.
