TrustWalletCore/WalletCore pod in Kotlin Multiplatform - almost no classes

[igemonster]

Describe the bug
Only a Crypto class is available from cocoapods.WalletCore in Kotlin (and CryptoMeta which doesn't look too different).

To Reproduce
In a Kotlin Multiplatform Mobile project for iOS and Android, try to access TrustWalletCore cocoapod from Kotlin:

// build.gradle.kts (:shared)
cocoapods {
   version = "1.0"
   podfile = project.file("../iosApp/Podfile")
   pod("WalletCore")
}

the Podfile is

target 'iosApp' do
  pod 'TrustWalletCore'
end

This successfully enables import cocoapods.WalletCore.* in shared/iosMain (see screenshot). Without the above cocoapods {...} the import is unavailable. So far so good.

Expected behavior
Many classes available for import in Kotlin: WalletCore classes like HDWallet, EthereumSigningInput, AnySigner etc.

Screenshots

Additional context
I can see/use these library classes in Swift, in Xcode via pod TrustWalletCore (and import WalletCore).

By the looks of it, the available Crypto class is generated from the Pod/library by commonizer in 0_WalletCore.knm (about 15 expect functions in total - a couple here for illustration):

@kotlin.commonizer.ObjCCallable public open external expect fun base58Encode(data: platform.Foundation.NSData): kotlin.String { /* compiled code */ }

@kotlin.commonizer.ObjCCallable public open external expect fun generateMnemonicFromSeed(seed: platform.Foundation.NSData): kotlin.String { /* compiled code */ }

Crypto has mnemonic-related functionality, as well as signHash/verifySignature but not much else.

AnySigner / HDWallet might need to add @objc to be exposed to Objc then Kotlin, EthereumSigningInput is a typealias of a SwiftProtobuf Message, I guess the same reason
