A Swift package for simple dependency injection that also supports Swift UI previews
Features
- ✅ Tiny footprint (
Injector.swiftandResolver.swiftare the only source files). - ✅ Supports SwiftUI previews.
- ✅ Great unit tests.
- ✅ Cool logo.
Usage
import Injector
// AppDelegate or App (SwiftUI)
Injector.setup {
$0.register(Person(), mock: Person_Mock(), for: PersonType.self)
$0.register(Cat(), mock: Cat_Mock(), for: CatType.self)
}
// App
let person = inject(PersonType.self) // Person
let cat = inject(CatType.self) // Cat
// Unit Test or SwiftUI Preview
let person = inject(PersonType.self) // Person_Mock
let cat = inject(CatType.self) // Cat_Mock
Why should my main app contain the mocks?
This is so mocks can be used in SwiftUI previews. I couldn’t find an alternative way but would be glad to hear it if you had one.
