In the world of mobile app development, two powerful tools have emerged to dominate the market: Swift and Flutter. As a developer, choosing the right tool can be overwhelming, especially when considering the nuances of each platform. In this article, we'll conduct a side-by-side comparison of Swift and Flutter for iOS development, highlighting their strengths and weaknesses.

Introduction

Mobile app development has come a long way since the introduction of Swift, Apple's modern programming language. Swift is fast, type-safe, and constantly evolving with new features being developed. To develop native iOS apps using Swift, developers need to use Apple's developer tools and frameworks, along with great documentation to get started.

On the other hand, Flutter is an open-source, multi-platform mobile SDK from Google that allows developers to build iOS and Android apps from the same source code. Flutter uses the Dart programming language and has excellent documentation available, making it a popular choice among developers. With its full support of native features, Flutter is similar to React Native, but with a more comprehensive approach.

Identical App for Comparison

When comparing Swift and Flutter for iOS development, it's essential to create an identical app using both technologies to justify the comparison points. In this article, we'll build an app that has a button called "Press Me" and prints the message "button pressed" to the console when the button is pressed.

Our main comparison points are:

  • Onboarding process
  • Build time
  • Reloading
  • Profiling
  • Accessibility
  • Building on CI
  • App size

Onboarding Process

To develop iOS apps with native tools, developers need to use Xcode as their IDE. The basic development kit for iOS development is included in Xcode itself, which can be installed on a macOS machine. Once Xcode is installed, developers can create a new iOS project by selecting File > New > Project > iOS > Single View App. They can then name the app and select Swift as the language.

For Flutter app development, developers need to set up Xcode + the Flutter binary installed, although they can also use Android Studio or IntelliJ IDEA for developing Flutter apps. The getting started guide for macOS explains all the setup required for iOS development. Once the setup is done, developers can run the following commands to create a new Flutter app:

flutter create native-compare

cd app_name

This command will generate the skeleton of the Flutter project. Developers can then implement the button using the Flutter Raised Button widget in the lib/main.dart file.

Analysis: Onboarding for Development

In terms of onboarding, native iOS development seems less painful and involves less configuration. Developers need only Xcode and a macOS machine to get started. There are many resources and books available online for learning Swift and iOS development. Flutter, on the other hand, requires Xcode + additional Flutter tools to get started with the development of iOS apps. As Flutter is still new in the market, there is comparatively less development resources available than for native iOS app development.
