The Xcode and Swift software development tools are both developed by Apple and are widely used by software development company across the world. A Swift app can be created for iOS, macOS, tvOS, or watchOS with this programming language. With Xcode, you can build Apple-related apps through an Integrated Development Environment (IDE). The two products play different roles in the development of Apple-based applications, even though you use them both.

What is Xcode?

As previously stated, Xcode is an IDE created by Apple that allows you to create apps for iOS, macOS, tvOS, and watchOS. Xcode, which was first released in 2003, is still evolving. Since version 5 x in 2013, Apple has published a new version every year. Apple extended development capabilities to the Xcode IDE platform when new devices such as the iPad, iPhone, Apple TV, and Apple Watch were released. The program is free to use for Mac users and is accessible on the Mac App Store.

Xcode includes editors, compilers, and other tools for creating sturdy and efficient apps. It is configurable, so the programmer may make changes as needed. Xcode’s Interface Builder is great for building Graphical User Interfaces without writing much code. It connects the UI controls to the code that has been implemented. The IDE also includes Apple developer documentation, which is beneficial to programmers.

Another benefit of Xcode is that it supports version control via GIT and subversions. For distributed teams, branch and merge processes are simple. Using the version editor, you can easily compare two versions of files, see commit logs, and discover who made changes to the code. Test-driven testing is also simple.

Xcode Coding Features

Xcode comes with a range of features you would expect in a software development company IDE.

Language Assistance

Xcode supports Swift and a variety of programming languages, including C, C++, Objective-C, Objective-C++, Java, Applescript, Python, React.js, and Ruby. It also supports Cocoa, Carbo, and Java programming models. Besides that, third parties also provide support for GNU Pascal, Free Pascal, Ada, C#, Perl, and D.

Output Capability

A fat binary file is created by Xcode. Code conforming to the Mach-0 format can be included for various architectures. It allows the application to run on PowerPC and Intel x86 platforms since they are universal binary files.

Compiling and Debugging

The iOS SDK is used by Xcode to compile and debug iOS applications that run on ARM architecture processors. You may use this functionality to compile and debug programs for iOS and the new Apple M1 chipset.

GUI tool

Xcode includes the GUI tool, Instruments, which runs DTrace, a dynamic tracing framework built by Sun Microsystems and distributed as part of OpenSolaris.

Xcode Usability Features

Xcode provides iOS app developers with a variety of functions to improve their workflow and optimise the software development process, in addition to the different coding tools.

Document tabs are included in the Xcode 12 version. A usability feature that was badly lacking in prior editions. It also allows you to change the font sizes in the navigator and provides improved code completion. Xcode 12 also supports universal apps, allowing you to test a single code base across numerous architectures. The Apple operating system family also has built-in multiplatform program templates. Using SwiftUI and the lifecycle APIs, you can create new projects and exchange code between macOS, iOS, watchOS, and tvOS.


Swift was introduced as a general-purpose, multi-paradigm, compiled programming language for iOS, macOS, watchOS, tvOS, Linux, and z/OS during Apple’s 2014 Worldwide Developers Conference. Swift, being a newcomer to these operating systems, capitalizes on the finest features of C and Objective C without being hampered by compatibility. It uses safe programming principles to add new features, making programming easier and more versatile. Swift’s foundation was built over time by improving its existing debugger, compiler, and framework architecture. Additionally, Automatic Reference Counting was implemented to facilitate memory management. The framework stack, which was originally built on a strong foundation of Cocoa and Foundation, has experienced considerable modifications and is now entirely controlled and standardised.

Swift Features

Swift uses a concise syntax and includes many modern components developers need to build fully-featured apps.

Rapid and powerful

Swift is quick. It uses the LLVM compiler to convert its code into optimised binaries that can operate on recent hardware architectures. It incorporates low-level primitives like operators, types, and flow control since it is Apple’s successor to C and Objective-C.

Compatibility with the Source

Swift provides binary compatibility for programs from version 5. This functionality eliminates the requirement for developers to integrate Swift libraries in their app code. These libraries are currently included in the code bases of the major Apple operating systems. This function reduces the app’s size and streamlines the development process.


Swift is still a very new language. Its syntax is simpler and more succinct when compared to C++, C#, Java, or even Python. You don’t have to terminate statements with a delimiter like a semi-colon, for example. It allows inferred types, and its modules supply the appropriate namespace, removing the need for headers. It also features great memory management capabilities, which limit the amount of memory used by your program by employing strict, deterministic reference counting.

Cross-Platform and Open Source

Swift is an open-source programming language. Developers may access the source code, a bug tracker, and user forums at swift.org, which is managed and maintained. Swift is also platform-independent. It currently supports Apple and Linux systems, with Windows support coming in September 2020 for early adopters.

What is the Difference Between Xcode and Swift?

Even though the headline of this piece is Xcode vs. Swift, these two Apple technologies do not compete. They work well together and are the recommended platform for creating programs for macOS, iOS, tvOS, and watchOS. Because Swift is open source and cross-platform, developers may leverage Xcode capabilities to create Linux and Windows programs in addition to Apple device apps.

If your primary device is a Mac, Swift and Xcode allow you to create apps for a wide range of scenarios. Even if these two technologies function well together, you have other options. You may create apps utilising these platforms since Xcode supports a broad range of programming languages like C, C++, Java, and Python. However, the true strength of integration comes from combining the two Apple technologies. Even though Windows support is still in its early stages, the Xcode and Swift combo might become one of the most popular software development platforms in the future.

So, as we stated, it is evident that Xcode and Swift cannot be compared. They both work well together to provide remarkable outcomes with minimal effort. Apple depends heavily on both, and it is apparent that Swift and Xcode are the ideal mix of a sophisticated application and an easy-to-use programming language.
