Fixing the @ import Error in Your KMM Project Using Android Studio

When developing a Kotlin Multiplatform Mobile (KMM) app, you may run into a recurring problem, especially when integrating C/C+ + modules. One specific error that can be frustrating is the following:

This issue can arise during the iOS build phase of your project, causing delays and confusion. In this guide, we will explore the root cause of this error and provide a step-by-step solution to resolve it, letting you get back to building your app efficiently.

Understanding the Problem

The error message you're encountering suggests that the module import system is effectively disabled in your current configuration while using iOS's Xcode development environment. When you use the @ import directive, it assumes that modules are enabled. However, in your case, they aren't, which results in the build failing.

Common Causes of the @ import Error

Xcode Configuration: The Xcode settings may not have modules enabled.

Podfile/.podspec Issues: Potential misconfiguration in your CocoaPods setup for integrating C/C+ + libraries.

Now, let's get to the solution.

The Solution: Adjusting Your Import Statements

While it may seem that resolving this error requires significant changes, the adjustment can be relatively simple.

Step-by-Step Resolution

Instead of using the following import statement in your header files:

You should switch to using the standard import format:

Why This Works

The # import directive is better suited to scenarios where module support is not guaranteed. It provides a clear path for the compiler to locate the header files, regardless of module settings.

This change should allow your project to build successfully, without running into module-related errors.

Additional Tips for KMM Development

To avoid further unexpected issues when working on KMM projects, consider the following tips:

Stay Updated: Ensure your development environment, including Xcode and Android Studio, is up to date. Compatibility can often resolve hidden issues.

Proper Configuration: Regularly review your Podfile and other configuration files for any discrepancies. A well-organized setup can save you a lot of headaches down the line.

Documentation: Refer to the KMM documentation for best practices on configuring and managing your project resources effectively.

Conclusion

Building a KMM app that integrates C/C+ + modules can pose unique challenges, but with the appropriate adjustments, you can streamline your workflow. By switching to the # import directive, you should resolve the module issue effectively. This small change can make a significant difference in your development journey, allowing you to focus on creating amazing user experiences across both iOS and Android platforms.
