Download vs Install Size #51

Open kibotu opened 7 months ago

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

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
