Resolving “All Bitcode Will Be Dropped” Warning in iOS Development

28 February 2025 Stephan Petzl Leave a comment Xcode

As developers transition their projects to iOS 9, many encounter warnings related to bitcode. Specifically, the warning “all bitcode will be dropped” is a common hurdle. This article provides a comprehensive guide to understanding and resolving this issue.

Understanding the Bitcode Warning

The warning arises when a library, such as GoogleMobileAds, is compiled without bitcode, yet bitcode is enabled in your Xcode project settings. This discrepancy leads to numerous warnings, potentially escalating to errors in future Xcode versions.

Solutions to the Bitcode Warning

To address the bitcode warning, consider the following solutions:

• Disable Bitcode: Navigate to your project settings and set Enable Bitcode to NO for both the target and the library build settings. This is the most straightforward solution if bitcode is not a requirement for your project.
• Update Libraries: If bitcode is essential, reach out to the library vendor for a version compiled with bitcode support. This ensures compatibility and future-proofs your application.

For more detailed guidance on managing bitcode settings, refer to Apple’s official documentation.

Addressing canOpenURL Errors

Alongside bitcode warnings, developers may encounter errors with the canOpenURL method in iOS 9. This involves app privacy changes, where querying URL schemes requires explicit declaration in your app’s info.plist.

• Add the LSApplicationQueriesSchemes key to your info.plist as an array, listing the URL schemes your app needs to query.
