First of all, mark as internal all the symbols (classes, fields, methods) you can

[Jan Holešovský]

@KamilH is right; to check what symbols are exported, you can use the 'nm' command, and also 'class-dump' from here: http://stevenygard.com/projects/class-dump/

[KamilH]

Or you can inspect <framework_name>.h file in the build folder, in my case it’s this one:

shared/build/xcode-frameworks/Debug/iphonesimulator17.2/shared.framework/Headers/shared.h

your goal would be to strip it as much as you can

Thanks, that helps.

if you r using cocoapods

you can disable embedBitcode

cocoapods {
        version = ""
        summary = ""
        homepage = ""
        name = ""

        framework {
            baseName = ""
            isStatic = false
// this line
embedBitcode(org.jetbrains.kotlin.gradle.plugin.mpp.BitcodeEmbeddingMode.DISABLE)
        }
}

[Pratik]

Thank you for the suggestion @Ahmed na but I am not using cocoapods.

[Jan Holešovský]

It's still worth adding embedBitcode("disable") to binaries { framework { ... though, I guess...

[Pratik]

Can I use embedBitcode even if I am not using cocoapods?

[Jan Holešovský]

Yes

[Jan Holešovský]

But not in the cocoapods { ... } thing

[Jan Holešovský]

This is what I have in our project:
ios {
binaries {
framework {
// bitcode is deprecated
embedBitcode("disable")

[Pratik]

Thanks, I will give it a try.

[Jan Holešovský]

One more thing for this framework thing; but that is for some additional fine-tuning is this one:
freeCompilerArgs += _listOf_("-linker-options", "-S -x -exported_symbols_list " + file("libs/exported-symbols.list").toString())

[Jan Holešovský]

Where the exported-symbols.list is a list of symbols I really really need to keep in the framework, and others are stripped. Use with care, though.
