Rust vs Swift: The Key Differences You Should Know

Are you interested in knowing about some key differences between Rust vs Swift? If yes, then you are at the right place. Rust vs Swift is always a big concern among the students. Before going deeper, Let’s start with a short introduction to each of these terms.

What is Rust?

Rust is a system programming language and was developed in 2006 by Graydon Hoare. It was primarily designed for safety as well as performance. Rust’s syntax is similar to the C ++ language.

Rust is free and open-source software, which means anyone who wants to use it can use the software freely. It is very fast and memory-efficient and by integrating with other programming languages, it can work on embedded systems.

Like calloc or malloc, there is no direct memory management which means Rust managed memory internally. The problems that are difficult to solve with C and C++ languages, it can solve them very easily. 

That’s why many organizations use the Rust programming language like Mozilla, Dropbox, Braintree, Cloudflare, npm. 

Rust Program Of Adding Two Numbers

Program

fn main()
{    
let num1 = 10;    
let num2 = 15;    
let add = num1 + num2;
println!(“The Sum of {0} and {1} is {2}”, num1, num2, add);
}

Output

The Sum of 10 and 15 is 25

Features of Rust

There are so many features of Rust and some of them are the following:

  • Zero Cost Abstraction
  • Guaranteed Memory Safety
  • Threads Without Data Races
  • Error Messages
  • Efficient C Bindings
  • Pattern Matching
  • Safe Memory Space Allocation
  • Move Semantics
  • Minimal Time

What is Swift?

Swift is a general-purpose programming language, and Apple Inc developed it. It is a powerful language and easy to learn also. For replacing Objective-C, it was designed, which was the earlier programming language of Apple. And it is used for mobile applications, desktop applications, scale-up of cloud services, system programming, and many other things.

Swift is built with a compiler, the LLVM compiler, and from version 6, it includes the Xcode. The code of the Swift is precise, safe, and it is very fast in the running. And it is a user-friendly programming language.

Swift Program Of Adding Two Numbers

Program

import Foundation
 
var number1 = 5; 
var number2 = 10; 
var add = Int(); 
add = number1+number2; 
print(“number1 + number2 = “,add); 

Output

$swift main.swift
number1 + number2 =  15

Features of Swift

There are so many features of Swift and some of them are the following:

  • Closures united with function pointers
  • Generics
  • Built-in error handling
  • Multiple return values and Tuples
  • Structs that support extensions, methods, and protocols
  • Functional programming patterns, like, map and filter
  • Fast iteration over a series or collection
  • Advanced control flow with do, guard, defer, and repeat keywords

Rust vs Swift: The Key Differences

  • Swift divides types into “value” and “reference” types, with the latter concealing the majority of the implementation details from the programmer. For better or worse, Rust makes references a first-class type, opening up the entire type system to the programmer.
  • Swift supports class inheritance. On the other hand, Rust does not.
  • Swift handles errors by throwing and catching exceptions. On the other hand, Rust prefers enumerated types to yield “success or failure” versions from fallible operations.
  • In Rust, most code constructs are expressions. On the other hand, in Swift, the distinction between “statement” and “expression” is more conventional.
  • Unlike Rust, Swift gives a comprehensive “properties” set of features (i.e., projected values, computed properties, property observers) similar to C#.
  • The type system in Rust handles several language features that have their own keywords and syntax in Swift (i.e., references, boxing, optional types, operator overloading).
  • Rust includes direct syntax for asynchronous programming. On the other hand, Swift does not.

Rust vs Swift: What Are Advantages and Disadvantages of Applying These Languages?

If you want to know more about Rust vs Swift in detail. Then by learning about the advantages and disadvantages, you will know. 

Advantages Of Using Rust

Memory Management

If we talk about memory management, it is one of the greatest benefits of using the Rust language. And mainly, it is designed for system programming. It doesn’t perform any background processing and doesn’t have a runtime like garbage collection. 

The unique advantage of this programming language is that it provides automatic memory management.

Concurrent

Rust is a concurrent programming language, and for concurrency, it provides built-in support.

Support Generic

Rust supports generics, and it has a good type system. So to programmers, there is no need to write the identical dictionary classes and array multiple times.

Error Catching

Rust is a programming language statically typed. So, at the compile time, errors are caught in this, and it doesn’t support the exceptions. For recoverable errors, it uses the type result <T, E> and uses panic! Macro to notify and to stop execution.

Optimal Code

For writing the optimal code, Rust allows the developers every time. So, it means to optimize the program, the programmers of Rust don’t need the understanding of the compiler code.

Documentation

Rust documentation describes the data structures working and gives the architectural guidelines on their proper usage. And to make it a good choice for most people, it has strong community support and windows compatibility.

Disadvantages of Using Rust

Compilation Speed

Rust has a slow compilation speed as compared to the other popular languages.

Complexity

Learning and understanding Rust programming language takes more time due to its complexity. 

Now, let’s look at the advantages and disadvantages of the Swift programming language, which will assist you to understand Rust vs Swift. 

Advantages of Using Swift

Memory Management

Swift gives automatic memory management and uses ARC (Automatic Reference Counting) to prevent memory leaks and for performance improvement.

Scalability

Swift is the proof of the future, and it means that by adding the new features, programmers can extend it.

Support Generic

In Swift, the support for generics is a similar one to the Rust. However, the difference which is essential one is the generic specialization in Swift is the detail of implementation, whereas Rust uses the monomorphiztions it.

Easy to Understand

The expressive syntax and it is easy to read, write and understand. 

Performance and Safety

Swift has statically typed characteristics, and it gives robust error handling that helps the programmers to prevent the code crash by knowing the errors before compilation. So, it offers good safety and performance.

Disadvantages of Using Swift 

Community

Although Swift is one of the fastest-growing programming languages, its community is still smaller in comparison to other popular open-source languages. Therefore, if you create a project with Swift language, you are more likely 

Conclusion: Rust vs Swift

The above information defines Rust vs Swift effectively. And after comparing it’s clear that both Rust and Swift are the popular ones but Rust vs Swift has its own set of advantages and disadvantages.

FAQs

Should I learn rust or Swift?

Rust is more useful than Swift for creating cross-platform applications, browser components, services, operating systems, file systems, game engines, and simulation engines for visual reality. If we talk about Swift, it melds only with the Apple ecosystem, whereas Rust can also be used to make the libraries so that other programming languages use.

Why is rust good for security?

With Rust, developers can avoid memory-handling mistakes that prevent security flaws, and it also aids in figuring out to developers why their software isn’t working.

Is Swift difficult to learn?

No, Swift is not so difficult programming language for someone who can put in the necessary effort. Swift has an easy-to-understand and expressive syntax. Swift’s creators wanted the language to be simple to read and write. Therefore, if you want to learn how to code, Swift is an excellent language to start.
