Getting null value exception when using in Appdelegate's didFinishLaunchingWithOptions

[zayantharani]

Below is the code:

@assembled private var dbManager: DBInterface

override init() {
    AssemblyHolder.defaultAssemblyType = ApplicationAssembly.self
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    print(appSettingsManager.getAppCenterKey())

    AppCenter.start(withAppSecret: Bundle.main.object(forInfoDictionaryKey: "app_center_key") as? String, services:[
      Analytics.self,
      Crashes.self
    ])
    
    return false
}


And by using this, I am getting an exception at Assembled.swift's wrappedValue get

Really sorry @zayantharani but I didn't see your issue until today, otherwise I would've responded sooner.

You're likely facing #2. The solution is to make sure you're declaring that you want DBInterface to be injectable by type or by key (at least one of the two), like this:

public override func makeBindings() {
        makeInjectable(dbInterface, byType: DbInterface.self)

^-- The first side of the argument is a reference to the function that builds dbInterface (whatever you've named it). Note that we're providing a reference to a function, not calling it.

Can you please confirm this is the error. If so, I'll happily take a pull request.

I'll add more features to Pilgrim soon - been very busy over last weeks.

Thank you for the reply. Actually I didn't make main.swift and was using AssemblyHolder.defaultAssemblyType = ApplicationAssembly.self in Appdelegate's init.

I realised this issue by having a look at the sample application
