Steps to determine iphone app size please?

Hello and thanks for your attention.

Can someone please list the exact steps to determine what your Iphone app size will be? I've tried the xcode run script here but don't see the output in the that it says will be available in the Build Results window.

Thanks in advance! I'm worried that my .app is 35 megs unzipped.

How to calculate the final size of an iPhone App before approval

but briefly, since your executable is encrypted for the store its not going to compress well; so for a rough guess, try

  1. open the .app bundle via right-click -> Show Package Contents (on Mac)
  2. locate the executable file and remember its (uncompressed) size (Size A)
  3. delete the executable from the bundle
  4. zip the bundle and remember the bundles compressed size (Size B)

Size C are the 100 KB from the additional files added to the bundle by Apple. The final calculation for the maximum size of your App is as follows:

A + B + C = maximum size of your App after approval

The calculation put in words: (uncompressed executable size) + (app bundle compressed but without executable) + 0,1 MB = maximum size of your App after approval.


Not sure if that calculation would be right for non universal binaries but for sure for universal binaries its off by several MB.
