stellar-ios-mac-sdk: Error on parsing payment operation's response

Payment operation’s response is not getting parsed. This used to work, so there might something changed on Horizon APIs. Tested with 1.1.5.

Error description:

HorizonRequestError: parsingResponseFailed : “The operation couldn’t be completed. (stellarsdk.XDRDecoder.Error error 6.)”

User code:

var memo: Memo

if let memoID = memoID {
    memo = Memo.id(memoID)
} else {
    memo = Memo.none
}

let paymentOperation = PaymentOperation(sourceAccount: keyPair, destination: try KeyPair(accountId: destinationAccountID), asset: asset, amount: amount)
let transaction = try Transaction(sourceAccount: accountResponse, operations: [paymentOperation], memo: memo, timeBounds: nil)
try transaction.sign(keyPair: keyPair, network: MPConfig.STELLAR_NETORK)
try StellarSDK(withHorizonUrl: MPConfig.URL_HORIZON).transactions.submitTransaction(transaction: transaction) { (transactionPostResponse) -> (Void) in
    
    switch transactionPostResponse {
//                    case .success(let submitTransactionResponse):
    case .success(_):
        fulfill(())
    case .failure(let horizonRequestError):
        reject(horizonRequestError)
    }
    
}
