Transactions are not sending

[Emin-Emini]

I tried to sign transaction exactly as in documentation:

func signTransaction() {
        guard let amountString = amountTextField.text else { return }
        guard let address = addressTextField.text else { return }
        let amount = Int((Double(amountString) ?? 0.0) * ethDivident)
        
        let signer = EIP155Signer(chainId: 1)
        let rawTransaction1 = EthereumRawTransaction(
            value: Wei("\(amount)") ?? 0,
            to: "\(address)",
            gasPrice: Int(gasPrice),
            gasLimit: 21000,
            nonce: 2
        )
        guard let signed = try? signer.hash(rawTransaction: rawTransaction1).toHexString() else { return }
        print(signed)
        
        
    }

It's printing transaction hash, but is not substracting any ethereum from the wallet. Also when I check the transaction on Etherium Scan is not showin at all.
