Dependency injection framework for Swift

Transcript

1. SWIFJECTION
 dependency injection framework for Swift Tomasz Grynfelder-Renk
2. • Why? • Who’s behind? • Features • Others • Hands-on Agenda 2
3. WHY?
4. Why? • missing reliable Swift DI solution back to the date • moving good practices from Objective-C code • simplify code testability • enforcing responsibility isolation • no need to inherit from NSObject in order to inject • conforming to Injectable protocol as the only requirement for pure-Swift injection 4
5. WHO’S BEHIND?
6. 6 Who’s behind? • created by the former iOS team members
 
 
 • with a little help from our friends from the community • proudly maintained by Applause • main development done from November 2016 to April 2017
7. FEATURES
8. 8 Features • Supported bindings: • type to type mapping (supports protocol-oriented programming) bindings.bind(object: MyClass.self, toType: MyProtocol.self) • instance to type mapping let object = MyClassConformingToMyProtocol() bindings.bind(object: object, toType: MyProtocol.self)
9. 9 Features • Supported bindings: • closure to type mapping bindings.bind(type: ClassConformingToProtocol.self) { injector in let object = MyClass() object.doAdditionalWork() return object } • singleton binding bindings.bindSingleton(forType: MyClass.self)
10. 10 Features • Creating objects using Swifjector: • with getObject(withType:) let object: MyClass? = injector.getObject(withType: MyClass.self) • using subscript let otherObject: MyClass? = injector[MyClass.self] as MyClass
11. 11 Features • Injecting dependencies or being injected with only Injectable protocol conformance: protocol Injectable { init?(injector: Injecting) func injectDependencies(injector: Injecting) }
