This article will explain to you how to avoid those problems by using the IdentifiedArray type.
Ambiguous Decoding
Dealing with a JSON network response in iOS projects used to be a pain. In Swift 4, we got native support for encoding and decoding JSON in the form of JSONEncoder and JSONDecoder that worked side-by-side with two protocols Encodable and Decodable to make converting between Swift types and JSON easy-peasy.

Cracking the iOS Interview
What are property observers in Swift?
In Swift, you can attach property observers to variables to perform a task when the value of the variable changes. These property observers are called willSet and didSet. The former runs right before the property changes, and the latter immediately after the changes are made.
In Swift, the didSet and willSet methods act as property observers.
willSet: Runs a piece of code right before property changes.didSet: Runs a piece of code right after the property has changed.
What is difference between open and final in Swift?
In Swift, the open keyword is used to indicate that a class, struct, or protocol can be subclassed or extended by other classes, structs or protocols within the same module or by other modules. This allows for greater flexibility in object-oriented programming and code reuse.
On the other hand, the final keyword is used to indicate that a class, struct, or protocol cannot be subclassed or extended. This means that once a class, struct, or protocol is marked as final, it cannot be used as a superclass or as a parent protocol.
iOS Good Practices
Are you aware of the life cycle of a UIViewController?
Being an iOS developer, it is very helpful to know the UIViewController life cycle in iOS. It helps you understand the different stages of a view controller's lifecycle and how to properly handle events and actions at each stage. This knowledge is necessary for creating stable and efficient iOS apps that properly handle memory management and user interactions. Additionally, understanding the UIViewController life cycle can help you debug issues and improve the overall user experience of your app.
