Download vs Install Size

[kibotu]

As far as I can tell, the output is always install size. For app install / update size optimisation we'd be interested in the compressed sizes as well. Any ideas?

Hi @kibotu, good question

From what I recall the output is actually the download size, but the universal one.
It should be possible to use thinning export options in order to have size report for a single variant, for a more "precise" download size.

And the thinning report has both compressed/download and uncompressed/install, which could be interesting for a more complete report.

In general, I think it's something interesting to look into and extend the tool to support :)

It could be something as:

• Allow the user to pass one ore many thinning_reference_device's
  • Default is universal, like currently is
  • Different business have different device models as their mostly used one(s), so it make sense to have them decide which, imo
• Support both download and install size in the report

What do you think @kibotu? Curious to about your ideas

great ideas! not sure yet how to parameterize this project accordingly just yet though

[kibotu]

I've removed vision and macos as build destination of the example app

and added -sdk iphoneos \ to the archive command

the binary sizes became smaller (from 4.8mb to 2.2mb) however if i run this on a few dependencies it quickly shows that the sizes don't add up to the final IPA.

IPA 17.1 MB

package 1 - 2,2 MB

package 2 - 8,4 MB

package 3 - 16,4 MB

package 4 - 10,9 MB

package 5 - 10,9 MB

package 6 - 12,7 MB

package 7 - 13,4 MB

there are 29 modules in total.

to me it looks like the size includes dependencies, which makes it difficult to measure a single package.

is there a way to exclude other dependencies when measuring by any chance?

Even if I subtract all the dependencies from each other, the app size still does not add up
