Generating double extended keys

[ghost]

guard let wallet = HDWallet(mnemonic: mnemonic, passphrase: pin) else {
  throw "New base wallet could not be generated"
}

let walletKey: PrivateKey = wallet.getKeyForCoin(coin: .cardano)

The code above is how I am currently generating private keys for Cardano, however, these keys produce an "Invalid extended key" error when signing transactions. Any idea of what I'm doing wrong?

I think this is a bug. For cardano we use 'double extended' private key, which has 6 32-byte parts. However, through the C (and thus Swift/Kotlin) interfaces (TWPrivateKey), only the first 32-bytes can be accessed.
Created issue #2136 .
