So, I already have a project with multiple pods installed. Here is the size of the main app's IPA as per app thinning report with Bitcode enabled:

App + On Demand Resources size: 30.7 MB compressed, 52 MB uncompressed

If I unzip the IPA file and take a look at its executable file, it's 22.5 MB.
So, I just create a new target in xcworkspace for App Clip. I neither add its target to Podfile nor add any code to the App Clip project. Then, I archive the app and export the app clip to check its size. Here is the outcome:

App + On Demand Resources size: 8.1 MB compressed, 22 MB uncompressed

If I check its executable, the size is 21.9 MB. How can I inspect what's adding to its size? or any suggestions on how can I trim down its executable's size?

A few things to note:

  • there are no bundle assets(images/videos) 

  • there are no libraries linked in Build Phases

  • I also used this command on my executable otool -L <path to the executable> to check for static libraries and the following was the outcome:

i faced the same issue.
I use flutter to build app, and app size is more than > 50mb.
Can not find the way to reduce size now.

otool will show you linked dynamic frameworks but not static frameworks that are compiled into your main executable. You can inspect symbols in dsym files to see what is in your main app binary and look for any static frameworks, or use a service like Emerge Tools to scan for these automatically.
