I tried it out with Yelp and Twitter, both had a lot of bloat due to not stripping binaries. You can see this in the large "String Table" in both screenshots.

Yelp also has a large exports section for the main app binary, that's usually a sign of a problem because the main binary doesn't need to export any symbols, only frameworks do that.

Twitter has a handful of 4MB images, much bigger than images you'd expect in an app. I took a look at a few of these and they are just gradient background images that could have been drawn with something like core graphics to completely eliminate the need for an image.

They're probably shipping their org chat. Artists and engineers are on separate teams, and when the artists want to redesign the look of the app it is easiest to photoshop a bunch of images.

Yeah those images need to go, I found them earlier when using assetutil ;)
