Challenges and Solutions in Developing a Kotlin Multi-platform FinTech App
Prepared by Romy Frederick
Developing a FinTech app, especially a digital banking solution, presents unique challenges related to data security and cross-platform support for Android and iOS. This case study dives deeper into the technical aspects and provides a brief walkthrough about how we provided solutions to address these challenges effectively.
The Challenge
- Cross-platform Support for Android and iOS
Considering the interest of the stakeholders on native apps and reducing the development efforts needed, we had to find an optimal solution which should balance maximum code sharing and performance close to native Android & iOS apps. Based on the research and findings we narrowed down to Kotlin multi-platform (KMM). It seamlessly supports both Android and iOS platforms and requires addressing some challenges such as platform-specific differences in architecture, UI/UX guidelines, and native features.
- Data Security
Next challenge ahead of us was data security. Data security is of utmost importance in financial/banking applications, given the sensitive nature of user information and transactional data.
- Third-Party Library Compatibility
Integrating third-party libraries and services was challenging during the development phase, as some libraries may not provide direct support for cross-platform development. KMM was in an early stage of release, so the support was limited during our development period. But as of now libraries are available for almost all of the major tasks.
The Result
Developing a Kotlin multi-platform FinTech app involved overcoming challenges related to data security and cross-platform support. By implementing robust encryption and cryptography techniques, secure authentication mechanisms, and a compliant backend infrastructure, developers could ensure the protection of sensitive user data. Leveraging Kotlin multi-platform's shared code capabilities, along with platform-specific UI frameworks enabled the development of cross-platform applications that provide a native-like experience. Thorough testing and quality assurance procedures helped in delivering a seamless user experience on both Android and iOS platforms. Overcoming these challenges resulted in the creation of secure, efficient, and user-friendly financial applications that catered to a broader user base.
