Issue
Why is the app size before stripping and after stripping noticeably different, often by a small percentage and smaller than expected?
Applies To
iOS customers of size analysis.
iOS builds.
Symptoms
After running a strip-symbols script, the app size appears reduced.
Resolution
The difference in these percentages from before stripping and after stripping is actually the download size. The insight gets anchored to install size on iOS and is shown as install size. You can check both sizes in your build comparison. See the Strip Debug Symbols docs for more on this.
