How to debug "Invalid Bundle" error which happens only after submitting to app store

Question

I have a lot of frameworks in my app. App works fine in adhoc/enterprise release. Only if I submit to the app store for testflight testing I get this error email from apple:

Dear developer,

We have discovered one or more issues with your recent delivery for "My app's name here". To process your delivery, the following issues must be corrected:

Invalid Bundle - One or more dynamic libraries that are referenced by your app are not present in the dylib search path.

Once these issues have been corrected, you can then redeliver the corrected binary.

Regards,

The App Store team

there is no specific information here. How can I debug it?

Answer 1

Got an answer from Apple Developer Technical Support which says it is a bug on Apple's side. this is the suggested workaround below which did not work for me:

To diagnose this issue, you should export the IPA you are sending to the App Store from Xcode. Since IPAs are zip files, you can decompress it by right clicking and saying Open With > Archive Utility. You should find your main executable inside the unzipped folder structure and run otool at the command line to see the library list: otool -L

The list of paths you get should match what you find inside of your IPA. All of your libraries should start with @rpath. A simple comparison of everything in this list with the unzipped IPA folders should reveal what is missing.

Once you know what is missing, go to your Xcode build phases setup. There should be a build phase for either Copy Files or Embed Frameworks that includes the missing library — you should just add the library to the list. If you don’t see either of these build phases, you can recreate it by adding a new Copy Files build phase, setting the Destination to Frameworks, and adding the library to the list, ensuring that Code Sign On Copy is checked.

If you don’t find anything missing in your main binary, make sure to do the same search on any other binaries you may have, like for a watchOS app or an iOS app extension.

If you find that all of the frameworks are in this build phase, please take a look at the Embedded Binaries section of your app target’s General page, and let me know if you see multiple levels of ../ next to the binary that you found is missing.

Please let me know if it works for you!

I have encountered the same issue when uploading an app with watch support to the app store.

I was able to solve it with the hint from the first answer, using otool -L to analyze the binary from the ipa or xcarchive. However, the problem was not with my frameworks (at @rpath) but with a swift lib. I noticed that libswiftWatchKit.dylib was missing in the frameworks folder.

The solution that worked for me was as simple as to set EMBEDDED_CONTENT_CONTAINS_SWIFT=YES in the build settings of the watch app (or the watch app extension, but not both). After that, all necessary swift libraries were correctly copied to the watch app path in the archive and upload to app store was working correctly.

Apparently, the watch app works and upload passes if you provide the necessary swift libraries only in the main app's folder.
