如何使用web3swift创建原始事务？

let web3 = Web3.InfuraMainnetWeb3()

let fromAddress = EthereumAddress("0xYourAddress")
let toAddress = EthereumAddress("0xRecipientAddress")
let amount = Web3.Utils.parseToBigUInt("1", units: .eth)
let gasPrice = Web3.Utils.parseToBigUInt("1000000000", units: .wei)
let gasLimit = BigUInt(21000)

let transaction = Transaction(
    from: fromAddress,
    to: toAddress,
    value: amount,
    gasPrice: gasPrice,
    gasLimit: gasLimit
)

let privateKey = Data(hex: "0xYourPrivateKey")
let signedTransaction = try transaction.sign(with: privateKey)

web3.eth.sendRawTransaction(signedTransaction) { result in
    switch result {
    case .success(let transactionHash):
        print("Transaction sent successfully. Hash: \(transactionHash)")
    case .failure(let error):
        print("Failed to send transaction. Error: \(error)")
    }
}
