To output the difference between two IPA files, you would typically need to compare the contents of these files. An IPA file is essentially a ZIP archive, so you can extract its contents and compare the files within. Here are the general steps you might follow:

  1. Extract the IPA Files: Rename the .ipa files to .zip and extract them using a tool like unzip.

  2. Compare the Contents: Use a file comparison tool to compare the extracted contents. Tools like diff on Unix-based systems or graphical tools like Beyond Compare can be used to see differences in files and directories.

  3. Focus on Key Files: Pay particular attention to the Payload directory, which contains the app bundle. You might want to compare the Info.plist files, binary executables, and any resource files.

  4. Automate with Scripts: You can automate this process with a script that extracts the IPAs and uses a command-line tool to compare the directories.

While the WWDC sessions do not directly address comparing IPA files, the Xcode essentials session discusses archiving and distributing apps, which is relevant to understanding the structure and distribution of IPA files.
