How do I validate payloads against a schema using JSON with Swift?

Validating JSON payloads against a schema in Swift can be accomplished by using the `JSONSchema` library or similar. Below is an example that demonstrates how to perform this validation.

import Foundation // Example JSON payload let jsonPayload = """ { "name": "John Doe", "age": 30 } """.data(using: .utf8)! // Example JSON schema let jsonSchema = """ { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "name": { "type": "string" }, "age": { "type": "integer" } }, "required": ["name", "age"] } """.data(using: .utf8)! do { // Validate the JSON payload against the schema let schema = try JSONSchema(json: jsonSchema) let isValid = schema.validate(json: jsonPayload) if isValid { print("Valid JSON payload") } else { print("Invalid JSON payload") } } catch { print("Error: \(error)") }
