iOS 18 brings exciting new possibilities for developers and users. With the latest updates, apps and games can become bigger and more powerful than ever before. These changes particularly affect size limits and the handling of on-demand resources. But what exactly does this mean for you as a user? Let's take a detailed look at what's new.
Apple traditionally sets size limits on apps to ensure that no single app takes up too much storage space. With the introduction of iOS 18, iPadOS 18, and tvOS 18, Apple has significantly increased these limits. This allows developers to create larger and more complex apps and games, which will ultimately improve your user experience.
Larger app bundles and expanded on-demand resources
With iOS 18, the maximum size of an app bundle was increased from 2 GB to 4 GB doubled. This means developers can now release larger apps without relying on on-demand downloads. This is especially useful for games, which often require large amounts of data. Since iOS 9, developers have been able to split their apps into smaller chunks and download only the essential parts immediately. Additional content is downloaded as needed, either when the app is first launched or in the background. This feature is called on-demand resources (ODR). With iOS 18, the limits for ODR were increased from 40GB to 70GB. This allows apps to host more content and download it on demand without burdening the user.
Benefits for users and developers
These changes have several advantages:
- Faster downloads: Since only the essential parts of the app are downloaded immediately, you can install apps faster and use them immediately.
- More efficient storage management: By using ODR, apps can download additional content only when they need it, saving storage space on your device.
- Improved gaming experience: Games can now offer larger levels and richer graphics, greatly improving your gaming experience.
Additional changes and updates
In addition to the larger app bundles and extended ODR limits, there are other notable changes:
- The additional 4GB limit on assets that can be downloaded immediately after installing an app bundle has been removed.
- Developers had complained about the Apple TV SDK only allowing 500 KB of persistent data storage. It is currently unclear whether this limit has changed, as the documentation has not yet been updated.
These improvements will especially benefit console games being developed for iOS and tvOS. The ability to use more on-demand resources means games can become more complex and graphically demanding, taking your gaming experience to a new level.
Future-oriented developments in iOS 18, iPadOS 18 and tvOS 18
iOS 18, iPadOS 18 and tvOS 18 bring significant changes that benefit both developers and users. The increase in size limits and improved on-demand resources make it possible to develop larger and more sophisticated apps and games. These developments will greatly improve your user experience on your iPhone, iPad and Apple TV. Stay up to date with the latest updates and look forward to an exciting future with iOS 18.
