To handle memory leaks, regularly analyze your app's memory usage with profiling tools. Identify and eliminate references to unused objects to free up memory.

Memory leaks can significantly degrade the performance of your cross-platform application, leading to slowdowns and crashes. To effectively handle memory leaks, start by regularly analyzing your app's memory usage using profiling tools such as Chrome DevTools for web applications or Xcode Instruments for iOS apps. These tools can help you identify patterns of memory consumption and locate objects that are not being released as expected. Focus on identifying and eliminating references to unused objects, as these can prevent the garbage collector from reclaiming memory. Common sources of memory leaks include event listeners that are not properly removed, circular references between objects, and static variables that retain references to objects longer than necessary. Implement best practices such as using weak references when appropriate and employing the observer pattern to manage events more effectively. Testing your app under various scenarios, particularly in environments that stress memory usage, can reveal hidden leaks. Additionally, encourage users to provide feedback on performance issues, as real-world usage can often uncover problems not evident during development. By systematically addressing memory leaks, you can enhance the performance and reliability of your application.
