Solidity 0.6

• There are new fallback functions appeared in Solidity 0.6

ABIEncoderV2:

• Add the ability to pass struct type into a function.

Hey I'm getting an error;

Thread 1: Swift runtime failure: Unexpectedly found nil while unwrapping an Optional value

on the following: (abiRecord.stateMutability == "payable" || abiRecord.payable!) in the parseFunction

I'm using a v6 solidity contract... Do you think this version is the issue?

[dangell7]

FIXED: Change abiRecord.payable! to abiRecord.payable != nil

I'm rocking a v6 token contract so I can update you as I go

@skywinder was this implemented? We are trying to encode structs into a function, but the data is not working. I am able to easily pass non-struct data into a function and have it encoded correctly.
