As developers, it’s crucial to stay informed about the various build options available in Xcode, especially when they affect app performance and compatibility with the App Store. One such option is “Enable Bitcode,” which has been a topic of discussion due to its implications on app submissions and performance. This guide aims to provide clarity on what enabling bitcode means for your iOS projects.
What is Bitcode?
Bitcode is an intermediate representation of your compiled program. When you enable bitcode in Xcode, your app is compiled into this intermediate form rather than directly into machine code. This allows Apple to optimize the app further when it’s submitted to the App Store. It also means that Apple can re-optimize your app in the future without requiring you to submit a new version.
Current Relevance of Bitcode
Initially introduced as a feature of iOS 9, bitcode was optional for iOS apps but required for watchOS apps. However, with the advent of Xcode 14, bitcode is no longer necessary for any platform, including watchOS and tvOS. The App Store has ceased accepting bitcode submissions from Xcode 14 onwards, and the feature is expected to be completely phased out in future Xcode releases.
Should You Enable Bitcode?
While bitcode used to offer advantages such as app size reduction and potential performance optimizations, its deprecation means that enabling it is no longer beneficial. In fact, enabling bitcode in Xcode 14 will generate warnings, suggesting developers update their projects to disable it.
Performance Implications
Enabling bitcode has traditionally not resulted in negative performance impacts. However, it could complicate internal distribution for testing purposes. For apps in the App Store, Apple would create separate binaries for different architectures, potentially reducing app size on devices. With the deprecation, these benefits are no longer applicable.
Conclusion
Given the current landscape, it’s advisable to disable bitcode in your Xcode projects. This aligns with Apple’s latest requirements and ensures a smooth submission process to the App Store.
