An implementation of JSON Schema in Swift. Supporting JSON Schema Draft 4, 6, 7, 2019-09, 2020-12.

The JSON Schema 2019-09 and 2020-12 support are incomplete and have gaps with some of the newer keywords.

JSONSchema.swift does not support remote referencing #9.

JSONSchema can be installed via CocoaPods.

pod 'JSONSchema'

import JSONSchema

try JSONSchema.validate(["name": "Eggs", "price": 34.99], schema: [
  "type": "object",
  "properties": [
    "name": ["type": "string"],
    "price": ["type": "number"],
  ],
  "required": ["name"],
])

Validate returns an enumeration ValidationResult which contains all validation errors.

print(try validate(["price": 34.99], schema: ["required": ["name"]]).errors)
>>> "Required property 'name' is missing."
