fastlane add_plugin store_sizer

About store_sizer

Estimates download and install sizes for your app, optionally checks and raise an error if the size exceeds given thresholds.

Some apps, specially games, struggle to keep their download sizes below the 100Mb limit, due to carrier network download limits on iOS, however the way people usually get around it is to send the build to iTunesConnect and later check the sizes reported by Apple.

It works by simulating the Apple encryption of the app executable (random bytes are written to the TEXT segments of the executable file), plus some artificially added files, followed by an ad-hoc export of the archive with the exportOptionsPlist thinning set to thin-for-all-variants

Also check for Apple's executable size constaints

Requires the Xcode .xcarchive, currently only iOS is supported.



Simulates encryption and returns a hash containing the reported size for all variants plus some info about the executable.


  • archive_path: path to your .xcarchive


Checks executable size constraints and max download size, raise an error if exceeded.


  • report: hash reported by the store_size_xcarchive action
  • ignore_universal: should the universal variant be ignored? true per default (only devices <= iOS 8 uses the universal variant)
  • max_wifi_size: overrides default 100Mb size check, pass 0 to disable wi-fi download size check


Check out the example Fastfile to see how to use this plugin.

Unfortunately an example .xcarchive can't be supplied since it will require distributing a signed executable, you will need to use your own.

Try it by cloning the repo, running fastlane install_plugins and bundle exec fastlane test archive_path:YourArchive.xcarchive.
