let's need build 50 ios apps same except name. can name (bundle display name) , bundleid changed after app built can prebuild them ahead of time without knowing name @ build time? change bundle id (in info.plist file) , it's going recognized different app ios , app store. and change display name change displayed name of app. you can read more bundle id here: https://developer.apple.com/library/ios/documentation/ides/conceptual/appdistributionguide/configuringyourapp/configuringyourapp.html though if app has special entitlements use bundle id (such icloud or push notifications), run issues.
