How can we deploy smart contract using webe3swift?

[ShoaibKakal]

In web3java, i can deploy a smart contract by following the methods

• Create .bin and .abi files from solidity file using solcjs library.
• Create java file using .abi and .bin files.
• Java file contains deploy() method to deploy a smart contract on Ethereum network.

Now in web3swift i don't see any method to deploy smart contract. I know there will be any other way of deploying but i don't know. can anyone please help in this regard?

Hello.
You can try using one of the following options.
There is definitely an improvement for that API coming but I cannot tell when exactly that will be done.

Options:

1. Create the whole transaction

// Some smart contract instance
let contract = web3Instance.contract(...)

// A transaction ready to be signed and executed
let writeTransaction = contract.prepareDeploy(bytecode: yourScBytecode)
...

2. Create only encoded data - how a transaction object will be created is up to you.

// It throws only if you give two functions with exactly the same name and input but different output.
// That's an invalid overloading of a function. We're safe here thus using `try!`.
let contract = try! EthereumContract(abi: [])

// There is also an option to pass constructor and input arguments
let encodedData = contract.deploy(smartContractBytecode)
...
