In this article, we'll delve into the world of swift app development and compare it side-by-side with Flutter, an open-source mobile SDK from Google. Our goal is to help you determine which platform is more suitable for your needs.
Introduction to Swift App Development
Swift is a modern, fast, and type-safe programming language that has revolutionized native iOS app development. Launched by Apple, Swift offers a seamless integration with the developer tools and frameworks provided by the tech giant. With great documentation available, starting a new project with Swift is a breeze.
Flutter: The Open-Source Mobile SDK
Flutter, on the other hand, is an open-source mobile SDK that enables developers to build iOS and Android apps from the same source code. Using the Dart programming language, Flutter offers a unique approach to app development, allowing for fast and efficient creation of cross-platform apps. With great documentation available, getting started with Flutter is easy.
Identical App for Comparison
To make a fair comparison between Swift and Flutter, we'll build an identical app using both technologies. Our sample app will feature a simple "Press Me" button that prints the message "button pressed" to the console when clicked. This allows us to compare key aspects such as onboarding process, build time, reloading, profiling, accessibility, building on CI, and app size.
Onboarding Process
The onboarding process for native iOS app development with Swift is straightforward. You'll need Xcode installed on a macOS machine, which includes the basic development kit for iOS development. Once you have Xcode set up, creating a new iOS project is a simple matter of selecting File > New > Project > iOS > Single View App and choosing Swift as the language.
In contrast, developing an app with Flutter requires setting up Xcode + the Flutter binary installed. You can also use Android Studio or IntelliJ IDEA for development, but Xcode is recommended for this comparison. The Flutter getting started guide for macOS explains the setup requirements in detail.
Build Time
Now that we have our apps set up, let's measure the build time for both native iOS (Swift) and Flutter apps. We'll compare clean builds by deleting all derived data and incremental builds.
The build time of native iOS apps can be easily measured using Xcode or the xcodebuild command line tool. To enable build timing summary in Xcode, run the following command: $ defaults write com.apple.dt.Xcode ShowBuildOperationDuration -bool YES. We'll also delete the derived data or clean the build folder to measure the build time for clean builds.
For Flutter apps, we can use the flutter doctor command to check the setup requirements. Once set up, running the flutter run command will launch the app in a simulator.
Analysis: Onboarding and Build Time
In conclusion, while both Swift and Flutter have their own strengths and weaknesses, the onboarding process for native iOS development with Swift seems less painful and requires less configuration. For Flutter, setting up Xcode + the Flutter binary installed is necessary for developing iOS apps.
The build time for both apps will vary depending on the complexity of your project. However, in this comparison, we've seen that native iOS app development with Swift tends to have faster build times compared to Flutter.

In this article, we've delved into the world of swift app development and compared it side-by-side with Flutter. By building an identical app using both technologies, we've highlighted key differences in onboarding process and build time. Whether you're a seasoned developer or just starting out, understanding the strengths and weaknesses of each platform is crucial for creating successful apps.
