A Quick Rundown Of Xcode

A Quick Rundown Of Xcode

Xcode is Apple’s development framework used in all iOS operating systems. Like their entire ecosystem, Xcode as an integrated development environment is also strong and almost impossible to break through. 

This article is a quick rundown of Xcode and aims to answer the following common questions our visitors and clients usually ask us during the discovery calls: 

  • Why and how do you use Xcode? 
  • Xcode vs Swift – what should developers choose?
  • What are the features of Xcode and how do they support iOS development?
  • What are the pros and cons of using Xcode?


What Is Xcode?

Xcode is an IDE (integrated development environment) created by Apple in 2003. The company dedicated Xcode for iOS development: building software programs and apps for iOS: iPhone, iPadOS, MacOS, WatchOS, tvOS and all other products under the Apple iOS system.

Xcode includes a toolkit that enables developers to write, debug, and test software. It also includes tools for file management and handling resources. Xcode has gone through a lot of updates since its inception in 2003. Its latest stable release was version 14.3 launched on March 30th, 2023. 
  • C
  • C++
  • Objective-C
  • Objective-C++
  • Java
  • AppleScript
  • Python
  • Ruby
  • ResEdit (Rez)
  • Swift


Xcode also supports third party programming languages like: 

  • GNU
  • Pascal
  • Free Pascal
  • Ada
  • C#
  • Go
  • erl, and D


How to Use Xcode On Windows And Linux?

Since Xcode is built by Apple themselves, it’s notoriously difficult to use it on operating systems like Windows. However, there are other cross-platform approaches to building iOS applications on third-party operating systems, including:

Visual Studio

Unlike Apple, Microsoft’s integrated development environment (IDE) allows the development of cross-platform applications using Xamarin. Xamarin is a powerful framework that supports the use of C# and .NET for building iOS, and Android cross-platform applications.

React Native

Another cross-platform approach is using React Native. React Native is Meta’s (Parent company of Facebook) own open-source framework. This framework enables developers to build cross-platform applications with the help of JavaScript and React. Secondly, React Native uses a single codebase for developing iOS and Android applications.


Similar to Apple and Meta, Google has its own mobile application SDK called Flutter. This framework uses Dart which is a client-optimized programming language. It also uses a single codebase for building high-performing cross-platform applications. There’s one more thing we need to add here. While these cross-platform approaches can develop applications on a non-Apple development setup they won’t provide the same level of integration as Xcode can.

Xcode Vs Swift - A Detailed Comparision


Swift is an open-source programming language that was launched by Apple in 2014. It allows developers to build applications for MacOS. tvOS. and other Apple operating systems. Xcode is similar to Swift because it also works with all iOS technologies. But, Xcode is an integrated development environment (IDE), not a programming language or framework. It streamlines the process of UI design, coding, testing, and debugging tasks when the application is in the development phase.


Developers can use Swift framework in the Xcode IDE. They can also write code in:

  • C
  • C++
  • Objective-C
  • Objective-C++
  • Java
  • Applescript
  • Xcode Python
  • React.js, and Ruby


Swift is also a relatively new framework with shorter syntax than C++, C#, or Java. Developers also have headers when developing with Xcode because it supports inferred types. Additionally Visual Studio Code Swift has top-notch memory management skills. These skills use accurate, deterministic reference counting that drastically lower’s your RAM requirements.


The Xcode Python development platform features tools that enable developers in improving and rewriting their code. They can also test a single code base on several architectures, which saves time in the development process.
Application’s efficiency and UI see a boost because of Swift as a primary development language. The code used in Swift is scalable and easier to maintain. Along with having extensive memory management.


Xcode and Swift have a few differences in terms of compatibility. Since the release of version 5, Swift comes with binary app compatibility. That’s why application developers no longer need to integrate Swift libraries in the code. Additionally, all of Apple’s operating system code bases already include these libraries making the development process quicker.


Xcode Cloud features specialized tools such as the iOS SDK for developing ARM- compatible applications. These tools also allow debugging programs that work with iOS and especially the latest M1 chipset. As Swift is an open-source software it’s completely free to use. It’s available on swift.org. It will give you the source code, a bug tracker, and a user forum where the whole Swift platform is managed. Swift is also cross-platform which means it can develop applications on the Windows and Linux operating systems.


Developers find Xcode’s SwiftUI productive for creating user interfaces for all Apple operating systems. SwiftUI also supports all the contemporary user interface designs like dynamic font, dark mode, and accessibility. It also combines with lifecycle APIs to exchange code across macOS, iOS, watchOS, and tvOS. Xcode comes with high-tech capabilities that improve workflow and make the software development process quicker. For instance, you can test a single code base on Xcode across different architectures using Xcode 12’s universal app readiness feature.

What Should Developers Choose Between Xcode And Swift?

Before developers make their choice between Swift or Xcode for the project, they need to understand three key elements. Even though Swift is a flexible and organized programming language, it’s still relatively new. That’s why developers face difficulty in finding sufficient resources, support, integrations, and options for the project’s success.

While Swift is compatible with the Apple OS, Xcode on the other hand provides a quicker user interface and workflow. Similarly, Xcode is a well-designed but old system compared to Swift which means developers may have to do a lot of troubleshooting.

One last thing, you should note down is that two Apple applications work flawlessly together. Experts recommend using them in your iOS project planning. Now, the question comes up about whether to incorporate one or both of them in your iOS app development process. The simple answer to this is; it depends on your requirements.

The way to a successful iOS development process lies in integrating the right iOS technology and having a firm grasp on the internal workings of both Xcode and Swift.

Top 16 Features of Xcode

Integrated Development Environment (IDE)

Xcode is an official IDE of Apple inc and provides developers with a complete and structured workflow that includes designing user interfaces, coding, testing, and debugging. You get all of these functionalities in all Apple devices ranging from Mac, iPhone, iPad, Apple TV, and Apple Watch.

Programming Languages

Xcode is compatible with Swift programming language which is known for being safe and fast. Xcode also supports C, C++, and Objective-C compilers for writing and managing code.


Another productive feature of Xcode is the simulator. The simulator enables developers to test and prototype applications in a simulated environment instead of a working device. A simulator can provide artificial environments for iPhone, iPad, Apple Watch, and Apple TV. You can also alter different settings, files, and operating system versions.


Xccode uses the instrument feature to profile and analyze the application. It also improves performance and detects if there are any memory issues remaining.

Create ML

Xcode gives developers the freedom to create and train their machine learning models using ML.

Reality Composer

With a reality composer developers can construct 3D models and augmented reality (AR) experiences.

Build System

Xcode enables developers to port their macOS apps to Apple Silicon. This way they can create a macOS application that is compatible with both Apple Silicon and Intel-based Mac computers.

Swift Packages

With Xcode, developers create a reusable code and then organize and share it with it other developers through Xcode projects.

User Interface Design

Xcode comes with features that design immersive UI/UX interfaces like SwiftUI. SwiftUI is a declarative framework which means it uses Swift code for designing interfaces. It also features an Interface Builder that creates a UI view graphically with a library of controls.


Xcode also enables developers to solve these common development errors:
  • Inspect the running apps to isolate bugs.
  • Locate crashes inside the system.
  • Identify excessive system resource usage.
  • Analyze memory bugs.
  • Find layout problems.


Developers can also set breakpoints on a running application for finding the cause of bugs. Identifying them by the changing of variables as they pass through their source and into the debugger.
