My biggest complaint with iOS development is how confusing Xcode's build system is. Extracting code out to shared frameworks is a confusing process and I can understand how so many of the top apps get it wrong. Also, it's clearly not a priority for Apple because they don't provide easy inspection tools. Best case for them is the user buys a new phone with more storage.
Yep this is exactly the problem I'm trying to solve! A lot of large app companies have switched from Xcode to third party build systems like Buck or Bazel. This can make things faster but even more confusing. I've found analyzing the actual build products to be the best solution to make sure nothing unintended is happening.
Interesting! Are you interested in going back into the build process to try and thin the app directly? Or just in helping developers identify the sources of app size?
I agree that it's not necessarily the most straightforwards, but I would think that in the hundreds of engineers they have at least some have figured out how it works to the point to which they can do this…
