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: Int = 0
}…
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 :)

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…
