AnyBuilder

public struct AnyBuilder : ViewControllerBuilder

Type-erased wrapper for ViewControllerBuilder. It can be used to shorten ViewControllerBuilder signatures in cases, where generic type information is not needed by consumer of the Route. Another reason to do this if this generic information obstructs your usage of ViewControllerBuilders, for example in cases where you want to create a UITabBarController with array of builders, and each of them has completely different type. In this case, you can convert them to array of AnyBuilder objects.

For example, when using navigation view builder, signature can become pretty long - NavigationSingleViewEmbeddingBuilder>. But generally, you don’t really care about resulting type as long as it’s type is ensured, and it is a UIViewController. In those cases, you could cast a builder like so: builder.asAnyBuilder which wraps builder in the AnyBuilder, which can be now used as return type that is much shorter.

  • Creates AnyBuilder instance.

    Declaration

    Swift

    public init<T>(builder: T, context: T.Context) where T : ViewControllerBuilder

    Parameters

    builder

    builder, whose type is going to be erased.
    context

    Context to be used when building ViewController

  • Creates AnyBuilder instance

    Declaration

    Swift

    public init<T>(builder: T) where T : ViewControllerBuilder, T.Context == Void

    Parameters

    builder

    builder, whose type is going to be erased.

  • Creates AnyBuilder instance

    Declaration

    Swift

    public init<T>(buildingBy: @escaping () throws -> T) where T : ViewController

    Parameters

    buildingBy

    closure to build ViewController when Route is executed.

  • Builds ViewController by running builder closure.

    Declaration

    Swift

    public func build(with context: ()) throws -> ViewController

    Parameters

    context

    context is always Void, because Builder and Context types have been erased and are unknown at this point.
