My .ipa build file is only around 60MB but when published to App STore, its around 200+MB
Why my when publishing increases my app size drastically?
The ipa you upload is the compressed size before app thinning and encryption. The App Store size is install size for a specific device. There are some built in tools like generating an app size thinning report that help estimate these numbers but none are completely accurate. The Emerge Tools service also helps you measure and understand these numbers.
