Send ETH on Kovan Testnet error：Swift.DecodingError.typeMismatch...

Error: Fatal error: ‘try!’ expression unexpectedly raised an error: Swift.DecodingError.typeMismatch(Swift.Array<Any>, Swift.DecodingError.Context(codingPath: [], debugDescription: “Expected to decode Array<Any> but found a dictionary instead.”, underlyingError: nil))

My Code:

func sendETHOnTestnet() {
        let password = "web3swift"
        let privateKey = "XXX"
        let formattedKey = privateKey.trimmingCharacters(in: .whitespacesAndNewlines)
        let dataKey = Data.fromHex(formattedKey)!
        let keystore = try! EthereumKeystoreV3(privateKey: dataKey, password: password)
        let keystoreManager = KeystoreManager([keystore! as EthereumKeystoreV3])
        print(keystoreManager.addresses!)
        
        let endpoint = "https://kovan.infura.io/v3/XXX"
        let web3 = try! Web3.new(URL(string: endpoint)!)
        
        let value = "0.001"
        let amount = Web3.Utils.parseToBigUInt(value, units: .eth)
        let walletAddress = keystore?.addresses?.first!
        let toAddress = EthereumAddress("0x50bc2c973adf4b0071ac85c23beb646e5288c1b5")!
        
        let contract = web3.contract(Web3.Utils.coldWalletABI, at: toAddress, abiVersion: 2)!
        var options = TransactionOptions.defaultOptions
        options.value = amount
        options.from = walletAddress
        options.gasPrice = .automatic
        options.gasLimit = .automatic
        let tx = contract.write("fallback", parameters: [AnyObject](), extraData: Data(), transactionOptions: options)!
        
        let result = try! tx.send(password: password)
        print(result)
        print(result.hash)
        print("----------")
    }

Update, fixed with: self.web3.addKeystoreManager(keystoreManager)

@BitSigOrg thanks for the update.

So probably we have to specify it clearly in the readme, @Iysbaera
