Description

The perf tests currently tars the iOS ipa as a proxy for final app size. Instead, an "app thinning report" could be generated from a xcarchive:

xcodebuild -exportArchive -archivePath  /path/to/xcarchive -exportPath /path/to/export/location -exportOptionsPlist ExportOptions.plist

See xcrun xcodebuild -h for the valid export options plist keys. This was the plist I used for veggieseasons:

$ plutil -p ExportOptions.plist 
{
  "method" => "ad-hoc"
  "thinning" => "<thin-for-all-variants>"
}

(The "thinning" value should probably be a specific hardware string like "iPhone10,1" to trade-off for test time).

This command generates the ipas, as well as a App Thinning Size Report.txt and app-thinning.plist.
