DIKit | A statically typed dependency injector for Swift | Build Tool library

DIKit is a Swift library typically used in Utilities, Build Tool applications. DIKit has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

DIKit provides interfaces to express dependency graph. A code generator named dikitgen finds implementations of the interfaces, and generate codes which satisfies dependency graph. The main parts of DIKit are injectable types and provider methods, and both of them are to declare dependencies of types. Injectable types are types that conform to Injectable protocol. A conformer of Injectable protocol must have associated type Dependency as a struct. You declare dependencies of the Injectable conformer as stored properties of Dependency type. For example, suppose we have ProfileViewController class, and its dependencies are User, APIClient and Database. Following example code illustrates how to declare dependencies by conforming Injectable protocol. Provider methods are methods of inheritor of Resolver protocol, which is a marker protocol for code generation. Provider methods declares that which non-injectable types can be instantiated automatically. In the example above, APIClient and Database are non-injectable type, but they can be provided in the same ways in most cases. In this situation, define provider methods for the types in an inheritor of Resolver protocol, so that instances of the types are provided automatically.
