Explanation:
A quick function can return several results. It is possible to achieve this by returning a tuple. We can bundle many values of different types into a tuple and return it.
Explanation:
Character is the incorrect value type for Swift.
Classes, structs, and enums are the three ways to declare a type in Swift. Value types (structs and enums) and reference types can be distinguished (classes). The distinction between them is defined by how they are kept in memory:
Explanation:
The if l syntax, which unwraps with a condition, is a typical manner of unwrapping optionals.
Explanation:
LLVM is a library for creating, optimizing, and generating intermediate and/or binary machine code. You can use LLVM as a compiler framework by providing both the "front end" (parser and lexer) and the "back end" (code that translates LLVM's representation to machine code).
Explanation:
In a quick programming language, we can specify constants by using the " let " keyword. In a quick programming language, the syntax for declaring a constant is as follows.
Explanation:
For iOS, macOS, watchOS, and tvOS, AFNetworking is a lovely networking library. It's based on the Foundation URL Loading System, which extends Cocoa's robust high-level networking abstractions. It offers a modular architecture that is easy to use and includes well-designed, feature-rich APIs.
The correct answer:
!
Explanation:
When we use the var keyword to declare stored instance properties, we create mutable instance properties, which means we can alter their values for each new instance. We create a mutable object, which is an object that can change its state, when we create an instance of a class that defines numerous public-stored attributes.
Explanation:
Swift is forced to report an error when the #error compiler directive is used. When you're giving code to someone and they need to fill in a critical value, such as an API key, this is beneficial.
