Question

Is there a way to figure out what contributes to the size of the generated iOS framework I have a framework that s around 50MB 90MB if I generate a fat framework with iOSX64 and iOSArm64 I wonder if there s any unused stuff that s somehow getting imported into the framework The generated header file is around 650KB so it is big there are about 300 classes

curioustechizen · Answer

Okay I Just realized that the framework also contains all transitive dependencies of my shared kotlin code That said all these dependencies are described in the header file anyway so the question remains Is it normal for a framework to be so large

Kris Wong · Answer

one that contains all dependencies yes

Kris Wong · Answer

if it s static it doesn t really matter how big it is the static linker will only link symbols that are used in the consuming project

Kris Wong · Answer

dynamic frameworks are another story

curioustechizen · Answer

Okay thanks for the explanation My concern with the framework size is not only about the app size it is about distributing the framework through cocoapods

curioustechizen · Answer

We re pre building the framework for distribution Currently we re building a fat framework containing all target architectures But that solves only one part of the problem It does not take into consideration debug versus release

curioustechizen · Answer

I was thinking we can fix this by simply publishing multiple pre built frameworks one each for release and debug But that might make it prohibitively expensive even using Git LFS if the frameworks weigh in at 90s of MBs

Kris Wong · Answer

if you are using cocoapods why are you bundling dependencies into your framework

curioustechizen · Answer

Sorry I think I did not explain that clearly enough We re using cocoapods for consuming our multiplatform framework from the iOS app The multiplatform code itself does not have any cocoapods dependencies Instead it has kotlin library dependencies that it fetches from maven declared using standard gradle `implementation` block

curioustechizen · Answer

My guess is that the framework file contains all the kotlin dependencies for example we use `ktor` `coroutines` and other such libs

< curioustechizen> I am running into something similar as my framework size is quite large Were you able to figure out why it was happening in your project

curioustechizen · Answer

< Amritansh> unfortunately no And I ve moved on from that project so I have no idea what happened finally
