To speed up load times for your app or game, there are several strategies you can employ based on the content presented at WWDC:
-
Preload Initial Content: For games, ensure that the initial stages are downloaded at launch. Aim to have around the first 15 minutes of gameplay bundled into your app store download. This allows players to start playing immediately after installation, while additional content is downloaded in the background. This approach is discussed in the session Design advanced games for Apple platforms.
-
Use On-Demand Resources: Utilize Apple's on-demand resources or background assets to download game data after the app installs. This helps in managing the app's size and load times effectively.
-
Optimize Asset Loading: In Xcode 16, you can use the new flame graph in Instruments to diagnose performance issues. For instance, if your app is loading assets serially on the main thread, consider parallelizing the loading using a task group and moving execution to the background. This is highlighted in the session What’s new in Xcode 16.
-
Concurrency for Image Processing: When processing images, use concurrency to speed up the process. Task groups can be used to perform requests in parallel, which is particularly useful for memory-intensive operations. This technique is explained in the session Discover Swift enhancements in the Vision framework.
By implementing these strategies, you can significantly reduce load times and improve the user experience on Apple platforms.
