Debugging Smart Contract Integration with iOS 17 using Web3.swift - Transaction Reverts
I'm optimizing some code but Does anyone know how to I'm confused about I'm having a hard time understanding I tried several approaches but none seem to work... During development on a decentralized finance (DeFi) application for iOS that integrates with Ethereum smart contracts, I've run into a tricky situation where transactions are reverting without clear feedback. Using the [Web3.swift](https://github.com/ Argentum) library, I can successfully connect to the Ethereum network and read the current state of my deployed contracts. However, when I attempt to execute a function that modifies the state, the transactions revert without returning any useful error messages. Here’s a snippet of the problematic code: ```swift let parameters: [Any] = [amount, recipientAddress] let transaction = web3.eth.sendTransaction( from: myWalletAddress, to: contractAddress, data: contract.methodName(parameters).data ) transaction.send() { result in switch result { case .success(let tx): print("Transaction successful: \(tx)") case .failure(let error): print("Transaction failed: \(error)") } } ``` I’ve verified that `amount` and `recipientAddress` are correctly formatted and valid addresses. The smart contract function I'm calling requires specific conditions to be met, so I also checked the contract for any preconditions that might not be satisfied. In an effort to debug, I added logs in the smart contract to see if the function was being called at all, but it seems like it’s not reaching there. I also attempted to simulate the transaction using `eth_call`, which returns a success but doesn’t execute any state change. To dig deeper, I used a tool called Ganache to run a local Ethereum network and checked for potential gas issues or state conflicts, but everything seems fine. The reverts are happening consistently, and I’m unsure if this is due to incorrect function parameters or perhaps a misunderstanding of the smart contract logic itself. Has anyone dealt with similar issues when integrating iOS apps with smart contracts using Web3.swift? What strategies can I employ to gain more insight into this transaction failure? Any debugging tips or insights into potential common pitfalls would be greatly appreciated! This is part of a larger application I'm building. Thanks in advance! Thanks, I really appreciate it! I'm coming from a different tech stack and learning Swift. What would be the recommended way to handle this? I'm working on a CLI tool that needs to handle this. What would be the recommended way to handle this? I'm working in a Linux environment. Any advice would be much appreciated.
