Reflection [DEPRECATED]

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

Usage

import Reflection
structPerson{varfirstName:StringvarlastName:Stringvarage:Int}
// Reflects the instance properties of type `Person`
letprops=tryproperties(Person.self)varperson=Person(firstName:"John", lastName:"Smith", age:35)
// Retrieves the value of `person.firstName`
letfirstName:String=tryget("firstName", from: person)
// Sets the value of `person.age`
tryset(36, key:"age", for:&person)
// Creates a `Person` from a dictionary
letfriend:Person=tryconstruct(dictionary:["firstName":"Sarah","lastName":"Gates","age":28])

Installation

import PackageDescription
letpackage=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.
