Cannot parse ABI with tuple[]

[izakpavel]

I am trying to use multicall smart contract (https://etherscan.io/address/0x5BA1e12693Dc8F9c48aAD8770482f4739bEeD696#code), but there is an issue when parsing the ABI with web3swift:

The tuple[] input parameter is parsed as an array of tuples, but there is a missing information about the tuple components which later prevents correct execution of the function...

the ABI: "[ { \"inputs\": [ { \"internalType\": \"bool\", \"name\": \"requireSuccess\", \"type\": \"bool\" }, { \"components\": [ {\"internalType\": \"address\", \"name\": \"target\", \"type\": \"address\" }, { \"internalType\": \"bytes\", \"name\": \"callData\", \"type\": \"bytes\" } ], \"internalType\": \"struct Multicall2.Call[]\", \"name\": \"calls\", \"type\": \"tuple[]\" } ], \"name\": \"tryAggregate\", \"outputs\": [ { \"components\": [ { \"internalType\": \"bool\", \"name\": \"success\", \"type\": \"bool\" }, { \"internalType\": \"bytes\", \"name\": \"returnData\", \"type\": \"bytes\" } ], \"internalType\": \"struct Multicall2.Result[]\", \"name\": \"returnData\", \"type\": \"tuple[]\" } ], \"stateMutability\": \"nonpayable\", \"type\": \"function\" } ]"

also, the method signatures are different to what js library produces when there are tuples involved

web3swift created method signature tryAggregate(bool,tuple(address,bytes)[]) but it needs to be just tryAggregate(bool,(address,bytes)[]) to get the correct keccak hash

Can you create a basic smart contract with a tuple for us to test? If not I can try to create one and test.

What solidity version are you using to compile the contract?

As I said, I was using multicall smart contract when faced the issue... I cannot create a testing one :(

My fixes are in this PR: #379

Well that's good news!!
