Reflection provides an API for advanced reflection at runtime including dynamic construction of types.

Usage

import Reflection
struct Person {   var firstName: String   var lastName: String   var age: Int }
// Reflects the instance properties of type Person let props = try properties(Person.self)
var person = Person(firstName: "John", lastName: "Smith", age: 35)
// Retrieves the value of person.firstName let firstName: String = try get("firstName", from: person)
// Sets the value of person.age try set(36, key: "age", for: &person)
// Creates a Person from a dictionary let friend: Person = try construct(dictionary: ["firstName" : "Sarah",                                                 "lastName" : "Gates",                                                 "age" : 28])

Installation

import PackageDescription
let package = Package(     dependencies: [         .Package(url: "https://github.com/Zewo/Reflection.git", majorVersion: 0, minor: 15),     ] )

Advanced Usage

// Reflection can be extended for higher-level packages to do mapping and serializing.
// Here is a simple Mappable protocol that allows deserializing of arbitrary nested structures.
import Reflection
typealias MappableDictionary = [String : Any]
enum Error : ErrorProtocol {     case missingRequiredValue(key: String) }
protocol Mappable {     init(dictionary: MappableDictionary) throws }
extension Mappable {
init(dictionary: MappableDictionary) throws {         self = try construct { property in             if let value = dictionary[property.key] {                 if let type = property.type as? Mappable.Type, let value = value as? MappableDictionary {                     return try type.init(dictionary: value)                 } else {                     return value                 }             } else {                 throw Error.missingRequiredValue(key: property.key)             }         }     }
}
struct Person : Mappable {     var firstName: String     var lastName: String     var age: Int     var phoneNumber: PhoneNumber }
struct PhoneNumber : Mappable {     var number: String     var type: String }
let dictionary = [     "firstName" : "Jane",     "lastName" : "Miller",     "age" : 54,     "phoneNumber" : [         "number" : "924-555-0294",         "type" : "work"     ] as MappableDictionary ] as MappableDictionary
let person = try Person(dictionary: dictionary)
