Instantiate

Type-safe and constructor injectable InterfaceBuilder protocols.

Summary

Storyboard and Nib is not type safe, if you use UIStoryboard or UINib, your code would be get some gloom. Instantiate take type-safe protocols for Storyboard and Nib. Lets’ improve our code with type-safe protocols!

as is

let storyboard = UIStoryboard(name: "ViewController", bundle: Bundle.main)
let vc = storyboard.instantiateInitialViewController() as! ViewController
vc.inject([1, 2, 3])

to be

import Instantiate
import InstantiateStandard
extension ViewController: StoryboardInstantiatable {}
let vc = ViewController(with: [1, 2, 3])

Protocols

StoryboardInstantiatable

Supports using viewController with Storyboard. Implement StoryboardInstantiatable at your viewController class, then you can use ViewController(with: Dependency).

NibInstantiatable

Supports using view with Nib. Implement NibInstantiatable at your view class, then you can use View(with: Dependency).

NibInstantiatableWrapper

Supports using view implements NibInstantiatable in other InterfaceBuilder. NibInstantiatableWrapper supports workaround. Make new UIView subclass, and implement NibInstantiatableWrapper, call loadView on init(coder:) and prepareForInterfaceBuilder. http://stackoverflow.com/questions/27807951/how-to-embed-a-custom-view-xib-in-a-storyboard-scene

Reusable

Supports UITableViewCell / UICollectionViewCell reuse features. Implement Reusable, then you can dequeue cell using Cell.dequeue(from: Parent, for: IndexPath, with: Dependency).

InstantiateStandard

StoryboardType and NibType required static var storyboard or static var nib. You need to write these values on own class, it is troublesome… Many developer define StoryboardName is same of ClassName, and if you are also, you can use InstantiateStandard. This libraly add default implementation of StoryboardType, NibType, and Reusable.
