JSON Structure is a type-oriented schema language for JSON, designed for defining data structures that can be validated and mapped to programming language types. + +## Features + +- **Schema Validation**: Validate JSON Structure schema documents for conformance +- **Instance Validation**: Validate JSON instances against JSON Structure schemas +- **Error Reporting**: Line/column information for validation errors +- **Full Type Support**: All 34 primitive and compound types from JSON Structure Core v0 +- **Cross-platform**: macOS, iOS, tvOS, watchOS, and Linux support +- **Pure Swift**: No Apple-only framework dependencies + +## Requirements + +- Swift 5.9+ +- macOS 10.15+ / iOS 13+ / tvOS 13+ / watchOS 6+ +- Linux support via Swift on Linux + +## Installation + +### Swift Package Manager + +Add the following to your `Package.swift` file: + +```swift +dependencies: [ + .package(url: "https://github.com/json-structure/sdk", from: "1.0.0") +] +``` + +Then add `JSONStructure` to your target dependencies: + +```swift +.target( + name: "YourTarget", + dependencies: ["JSONStructure"] +) +``` + +## Usage + +### Schema Validation + +Validate that a JSON Structure schema document is syntactically and semantically correct: + +```swift +import JSONStructure + +let validator = SchemaValidator() + +let schema: [String: Any] = [ + "$id": "urn:example:person", + "name": "Person", + "type": "object", + "properties": [ + "name": ["type": "string"], + "age": ["type": "int32"] + ], + "required": ["name"] +] + +let result = validator.validate(schema) + +if result.isValid { + print("Schema is valid!") +} else { + for error in result.errors { + print("Error at \(error.path): \(error.message)") + } +} +``` + +### Instance Validation + +Validate JSON data instances against a JSON Structure schema: + +```swift +import JSONStructure + +let schema: [String: Any] = [ + "$id": "urn:example:person", + "name": "Person", + "type": "object", + "properties": [ + "name": ["type": "string"], + "age": ["type": "int32"] + ], + "required": ["name"] +] + +let instance: [String: Any] = [ + "name": "John Doe", + "age": 30 +] +

print("Error at \(error.path): \(error.message)") + } +} +``` + +### Validation from JSON Strings + +You can also validate from JSON strings or data: + +```swift +import JSONStructure + +let
