Mobile app development is a rapidly growing industry, and mobile software development kits (SDKs) are at the forefront of this growth. As the demand for innovative and user-friendly apps continues to rise, it's essential for developers to create high-quality SDKs that deliver exceptional experiences. In this article, we'll explore best practices for developing a mobile SDK, helping you stand out from the crowd and unlock swift app development success.

Make Integration Easy Peasy

Developers use SDKs to save time and effort. However, if the integration process is complicated and time-consuming, they might not even give it a chance. To simplify the process, consider using a dependency manager like CocoaPods or a repository manager like JFrog Artifactory. Your goal should be to allow developers to integrate your SDK in under 10 minutes.

Provide Clear Documentation

Clear and well-organized documentation is crucial for delivering a world-class SDK experience. You want your users to successfully use your SDK's features and see its value, so provide comprehensive documentation that covers all methods and APIs. Include "getting started" guides and plenty of sample code to make it easy for developers to get up and running quickly.

Fit Seamlessly into Your Users' Workflow

To ensure a smooth adoption process, you must have a deep understanding of your users' workflow, tools, and common pain points. Integrating with the most commonly used tools by developers in your sphere makes it easier for them to adopt your SDK. At Luciq, we integrate with issue trackers, help desks, communication tools, and other popular platforms like Zapier.

Conserve Resources

With an average of 18.2 SDKs integrated into apps, resource consumption can quickly add up. Treat every resource – processing power, memory, network, and battery – as a precious limited resource. Use only what you need, and strive to be a great guest in your users' apps.

Be Transparent About Permissions

Clearly and transparently communicate the permissions your SDK will require to function, and explain why they're necessary. Avoid asking for unnecessary permissions that could impact user trust. Ideally, your SDK won't need any additional permissions beyond what the app already has, but be prepared to provide explanations if needed.

Minimize Third-Party Libraries

While third-party libraries can simplify development, they can also increase the size of your SDK and introduce hidden bugs. Only use external libraries when absolutely necessary, and take precautions like renaming classes to avoid conflicts. Be prepared for any bugs that may arise and have a plan in place to address them.

Keep Your SDK Size Small

A small SDK size is crucial for maintaining a positive user experience. Make sure you compress and optimize all resources included in your SDK, and keep dependencies to a minimum. Remember, your SDK is likely one of many integrated into the app, so every byte counts.

Don't Conflict with Your Users' App

Your SDK should never change the behavior of the host app. This can quickly lead to your SDK being eliminated from the stack. Use a prefix for all resource names in your SDK to ensure they're unique and won't cause issues for the app.

Maintain Compatibility Across OS Versions

To reach a wider audience, maintain compatibility with multiple OS versions. Promptly support the latest OS version and architecture, while also setting a reasonable minimum OS version to support. Avoid dropping support until you're confident it won't have a significant impact on your users.

Raise Your Quality Bar

Developers already have plenty of bugs and crashes to worry about – don't add to their stress by releasing a buggy SDK. Test exhaustively, and only release your SDK when you're confident it won't disrupt the apps that use it. Aim for a zero-bug policy, and be prepared to provide good support and speedy fixes.

Prioritize Security and Privacy

The security and privacy of your users' app and their end-users are top priorities. Handle sensitive data like PII or credit card information with care, using SSL on all network calls and certificate pinning to prevent man-in-the-middle attacks. Avoid storing any information locally, and use encryption to protect it.
