Dependency injection

[luca-i]

How should I do dependency injection?
Suppose I need to access an external service inside my login viewcontroller (the initial viewcontroller for loginStoryboard). The service is defined as a protocol.
I could use an implicitly unwrapped optional, but how could I set it?
Thank you, Luca-

Hey @luca-i,

Been giving your issue some thought and am ready some more information. How are you currently instantiating your login viewcontroller? Should help us find a solution for your issue.

Thank you @initFabian,
since the initial view controller is instantiated with Cely.setup static method, I can't inject any dependencies in it (i'm talking about something like https://www.natashatherobot.com/ios-view-controller-data-injection-with-storyboards-and-segues-in-swift/).

Hey @luca-i,

Since Cely simply references the rootViewController, you should still have access to the loginVC. For example, you can still run code like this inside of your AppDelegate.

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        Cely.setup(with: window, forModel: User(), requiredProperties: [User.Property.token], withOptions: [
            .loginStoryboard: UIStoryboard(name: "Login", bundle: nil)
        ])

        if let loginVC = window?.rootViewController as? MyCustomLoginViewController {
            loginVC.dependency = ...
        }
...
}
