Swift: Dependency Injection Tutorial (2022) - iOS
ΠΠ΅ΡΠ΅Π³Π»ΡΠ΄ΡΠ² 34,316
ΠΠ΅Π½Ρ ΡΠΎΠΌΡIn this video we take a practical look at dependency injection in Swift by using protocols. Dependency Injection is a powerful pattern to build scalable large applications with decoupled logic. It allows objects to use common functionality in an agnostic way; such that one object does not know where the functionality comes from. We'll be working in Xcode 12 and Swift 5 to demonstrate this with multiple targets.

Why did you use singleton despite you used dependency injection? i know that one of dependency injection benefit is to remove singleton!!

@ahmetbugraozcan6742 Π ΡΠΊ ΡΠΎΠΌΡ
It was great video but I have different question. What should we do when we require a data to multiple places? I was thinking dependency injection is related to this but it seems it doesnt so I am little confused.

please can we have another DI tutorials that talks more in depth concepts and how to work with MVVM Much appreciated !!!

Can you possibly explain the @escaping closures and callback and the reason for this instead of making the function return something? New to iOS development
@novo4249 2 ΡΠΎΠΊΠΈ ΡΠΎΠΌΡ
Hi Cesar, using callback function to return a value is a common approach to achieve asynchronous function in programming. In this case, the function have to be asynchronous as the network API call is not returning the value immediately. @escaping closure is just the Swift way of implementing callback.

@tokero5199 2 ΡΠΎΠΊΠΈ ΡΠΎΠΌΡ
This was a very nice tutorial. I know it's slightly off topic but how would you handle dependencies of your separated out targets. Let's say you network module depends on alamofire but you do not want you main app to depend on alamofire.
@ApoCaLypSeXVII Π ΡΠΊ ΡΠΎΠΌΡ
I mean correct me if I'm wrong but once you import 3rd party dependencies to assist with backend network calls wouldn't it now become a global asset to the whole project? Anything having to do with the API would require you importing in alamofire for each file no?
@RajrkSunny Π ΡΠΊ ΡΠΎΠΌΡ
@@ApoCaLypSeXVII I think we can also setup 3rd party for individual targets.
