1. Reduce App Size: App size is a major factor when it comes to optimizing the performance of an iOS app. To reduce the size of an app, you can use techniques such as code stripping, image optimization, and removing unused resources.
2. Leverage Caching: Caching is a great way to improve the performance of an iOS app. You can use caching to store data and retrieve it quickly, reducing the need to make API calls.
3. Optimize Network Requests: Network requests can be a major source of lag in an app. To optimize network requests, you can use techniques such as lazy loading, image optimization, and request batching.
4. Use Multithreading: Multithreading is a great way to improve the performance of an iOS app. By utilizing multiple threads, you can ensure that the user interface remains responsive while long-running tasks are running in the background.
5. Optimize Your Database: Your database can be a major source of lag in an app. To optimize your database, you can use techniques such as indexing, query optimization, and denormalization.
