To ensure performance optimization of an iOS application, I focus on implementing efficient algorithms, minimizing loading times, and utilizing low-power techniques. I also conduct profiling to identify bottlenecks and ensure tasks are properly managed using multithreading.

One challenging bug involved a memory leak that created crashes during high usage periods. I used instruments to trace memory allocations and identified the root cause in my delegate pattern. Resolving this not only improved stability but also enhanced user experience.

I have extensive experience in both Objective-C and Swift. I prefer Swift for its safety features and readability, but I have utilized Objective-C for legacy projects and understand its runtime and memory management intricacies, which helps in optimizing code efficiency.

I approach code reviews with a collaborative mindset, focusing on code quality, readability, and best practices. I provide constructive feedback while being open to new ideas, ensuring we adopt solutions that enhance the overall project's maintainability.

In a previous project, I collaborated closely with designers to rework a feature’s UI. We gathered user feedback, iterated on design proposals, and ultimately delivered a more intuitive interface, which increased engagement metrics significantly.

I stay updated on iOS development trends by attending conferences, participating in online forums, and following thought leaders in the tech community. I also regularly read articles and documentation from Apple to understand new features and best practices.

When handling multiple features, I prioritize tasks based on deadlines, complexity, and interdependencies. I ensure open communication with my team to set realistic timelines and adjust priorities as necessary to maintain project flow.

I view feedback from product managers as integral to the development process. I take time to fully understand their insights, align them with user needs, and adjust my approach as necessary, ensuring that the final product aligns with business goals while maintaining technical integrity.

Testing is crucial in my development workflow; I implement unit tests and conduct integration testing to catch issues early. I also practice continuous integration and deploy test builds to gather user feedback during the development process to ensure quality.

In evaluating trade-offs for architectural decisions, I consider factors such as performance, scalability, and maintainability. I weigh immediate benefits against long-term sustainability and team capabilities to choose solutions that align with both the project and organizational goals.
