Method compactMap removes nil results from optional value sequences during transformation, and flatMap flattens nested sequences into a single level sequence.
Variadic parameters are useful when you want to create a function that can take any number of arguments of a specific type without specifying them individually.
Both computed properties and methods can provide dynamic behavior, allowing you to calculate values or perform actions based on the current state of an instance.
Capitalizing first letter of each word, the first letter of a sentence, or all caps lies in the specific style and purpose of text presentation.
It's important to consider the specific requirements of your tasks and choose the appropriate session type and configuration accordingly.
One of the basic operations in Swift is to compare two strings for equality or order. There are different ways to do that, depending on your needs.

This can be useful when the initial value of a variable is expensive to compute, or when it is not needed until it is actually used in the code.
In Swift, @objc is used to expose a method, property, or class to Objective-C, while @nonobjc is used to explicitly hide an entity from Objective-C.
The main difference between callAsFunction and @dynamicCallable is that the former is more static and type-safe, while the latter is more dynamic and flexible.
