(NOTE: For this article will be using iOS in the examples, but is applicable to all reactive MVVM architectures. Will also be using google style guidelines to format the constructs) Just want to share an idea when we are implementing MVVM pattern with reactive programming such as RxSwift/RxJava, etc. Our…

Recently, our team was tasked with developing a UI component, passed in by the the design team. This was to be, in the future, used across our app. Requirements:

I think it should be reconsidered. Many a times I come across UITableViewCell/UICollectionViewCell subclasses which, in my opinion, seem too niche of an implementation. It needs to abstracted. Requirement: To display, say, a collection view in a row of a table view. Widely implemented solution: Create a UITableViewCell sublclass and add a collection view…

TLDR: It is for when you are interested in: • compiler optimization. • Generate compile error in-case a new case/property is added. Applicable to enum and struct constructs. Targeted at library authors. NOTE: @frozen is only applicable when developing on something called as Library Evolution mode, introduced in Swift 5.0…

These are access modifiers for the individual methods of a struct or non-class protocols. These apply also to the getter and setter methods of properties. To understand these keywords, lets construct a struct MyStruct holding property underlyingValue of type Int: class MyStruct { private var underlyingValue…

Generics for protocols are what they are. They enable us to write a common protocol that can accomodate variance in data types, for the same names, in the classes that conform to the protocol (NOTE: THIS IS STATEMENT IS JUST MY ATTEMPT TO DEFINE associatedtype IN A SINGLE SENTENCE. DO…

TLDR; It is like compiler substitution :) HTTR; To understand associatedtypes: https://02infinity.medium.com/understanding-swift-protocol-associated-types-ca717d091b56 I’ve had a hard time wrapping my head around ‘some’ keyword (introduced in swift 5.1). Now that I have that “Ah-ha!” moment, I thought I may be able to help others understand, with this article. I’ll start with…
