Encountering the “dyld: Library not loaded” error when running your iOS app on a device can be a frustrating experience. This error typically indicates that a required framework is not being properly linked or embedded within the application. This guide will walk you through the necessary steps to resolve this issue, ensuring your app runs smoothly on all devices.
Understanding the Issue
The error message usually looks something like this:
dyld: Library not loaded: @rpath/FrameworkTest03.framework/FrameworkTest03
Referenced from: /var/mobile/Applications/FA6BAAC8-1AAD-49B4-8326-F30F66458CB6/FrameworkTest03App.app/FrameworkTest03App
Reason: image not foundThis error occurs because the dynamic linker cannot find the specified framework at runtime. This can happen if the framework is not correctly embedded in the application bundle or if there are issues with the framework’s path settings.
Steps to Resolve the Issue
Follow these steps to ensure your framework is correctly embedded and linked:
- Open Your Project in Xcode: Navigate to the General tab of your target settings.
- Add the Framework to Embedded Binaries: Under the Embedded Binaries section, click the “+” button and add your framework. This ensures the framework is copied into the compiled app so it can be linked at runtime.
- Verify Framework Settings: Ensure that your framework is also listed under the Linked Frameworks and Libraries section.
- Clean and Build Your Project: Use the shortcut
Command+Shift+Kto clean your project, then build it again usingCommand+B. - Check Runpath Search Paths: In the Build Settings tab, ensure that the Runpath Search Paths (LD_RUNPATH_SEARCH_PATHS) include
@executable_path/Frameworks. - Optional Settings for Older iOS Versions: If your app needs to support iOS versions earlier than 8, you may need to change the framework’s Mach-O Type to Static Library under the framework’s Build Settings.
Additional Tips
If you are still experiencing issues, consider the following additional tips:
- Ensure the framework is set to Optional instead of Required under the General tab if you are facing issues with backward compatibility.
- For Swift frameworks, enable the “Always Embed Swift Standard Libraries” option under Build Options.
- Double-check the framework’s path and ensure it is correctly referenced in the project settings.
Conclusion
By following these steps, you should be able to resolve the “dyld: Library not loaded” error and ensure your iOS app runs smoothly on all devices. Properly embedding and linking frameworks is crucial for the stability of your app, especially when dealing with dynamic frameworks.
