Summary
The validation failure in XCode occurs due to invalid signature and invalid bundle issues. This happens when the application is not signed with a distribution certificate or when the bundle contains disallowed files.
Root Cause
The root cause of this issue is:
- Incorrect code signing settings in Xcode
- Use of ad hoc or development certificate instead of a distribution certificate
- Bundle containing disallowed files, such as the ‘Frameworks’ file in the UnityFramework.framework directory
- Building the application with a Simulator target instead of a Release target
Why This Happens in Real Systems
This issue occurs in real systems when:
- Developers overlook code signing settings and use the wrong type of certificate
- Automated build processes are not properly configured
- Third-party libraries or frameworks are not properly integrated into the project
- Xcode project settings are not correctly configured at the target level
Real-World Impact
The impact of this issue includes:
- Failed app store submissions
- Delayed release of applications
- Increased development time and costs
- Frustration and decreased productivity for developers
Example or Code (if necessary and relevant)
# Clean and rebuild the release target
xcodebuild clean
xcodebuild -scheme HoloMeet -configuration Release
How Senior Engineers Fix It
Senior engineers fix this issue by:
- Verifying code signing settings in Xcode
- Using the correct distribution certificate
- Ensuring the bundle does not contain disallowed files
- Building the application with a Release target
- Cleaning and rebuilding the project as needed
Why Juniors Miss It
Junior engineers may miss this issue because they:
- Lack experience with Xcode and code signing
- Overlook important details in the project settings
- Do not fully understand the differences between ad hoc, development, and distribution certificates
- Rely too heavily on automated processes without proper configuration and testing
