Create new contract method.

Hi,
https://ropsten.etherscan.io/address/0x1aa657b495a11838b121d3b3c38f196dba3f814c#code
Above is my smart contract method..

I need to call the method "deposit"....which is located as 4th method..

As am new to the Web3swift and smart contract I cant able to call that method successfully.

What I tried:
My code:

func prepareTransaction() {
DispatchQueue.global().async {
let value: String = "0.1"
let amount = Web3.Utils.parseToBigUInt(value, units: .eth)
let addressFrom: String = "0x4E0d3bb7359C8384bca20................"
guard let ethAddressFrom = EthereumAddress(addressFrom) else {return}

        guard let ethContractAddress = EthereumAddress(contractAddress) else {return}

        let web3 = Web3.InfuraRopstenWeb3() //or any test network
        web3.addKeystoreManager(KeystoreManager.defaultManager)

        var options = TransactionOptions.defaultOptions
        options.from = ethAddressFrom
        options.gasPrice = .manual(BigUInt("200000000"))
        options.gasLimit = .manual(BigUInt("27500"))
        //options.value = amount // or any other value you want to send

        guard let contract = web3.contract(myTestABI, at: ethContractAddress, abiVersion: 2) else {return}
                     
        let transaction = contract.write("deposit", parameters: [ethContractAddress, amount!] as [AnyObject], extraData: Data(), transactionOptions: options)!
        
        do {
            let send = try transaction.send(password: "")
            print("trans res", send.transaction)
        } catch(let err) {
            print("trans err", err)
        }
        
    }
}

ABI I GOT USING THE API: https://api-ropsten.etherscan.io/api?module=contract&action=getabi&address=0x1aa657b495a11838b121d3b3..................

From above API am using the key "result" as string.
