EIP712 iOS Not Working

[trevormil]

As described in #3049, Trust Wallet is having trouble signing EIP712 signed data on iOS.

I am using Web3Modal and wagmi. When I call signTypedData() on desktop, it works fine. When I attempt to call it with Trust Wallet iOS, it does not produce the same signature.

Here is my _app.tsx.

import { EthereumClient, w3mConnectors, w3mProvider } from '@web3modal/ethereum'
import { Web3Modal } from '@web3modal/react'
import { configureChains, createClient, WagmiConfig } from 'wagmi'
import { mainnet } from 'wagmi/chains'

const chains = [mainnet]
const projectId = 'febf8d9986a2cd637fa4004338dad39b'

const { provider } = configureChains(chains, [w3mProvider({ projectId })])
const wagmiClient = createClient({
    autoConnect: true,
    connectors: w3mConnectors({ projectId, version: 1, chains }),
    provider,
})
const ethereumClient = new EthereumClient(wagmiClient, chains)
const queryClient = new QueryClient()

and here is my sign function:

import { disconnect as disconnectWeb3, signMessage, signTypedData } from "@wagmi/core";
...
...
const sig = await signTypedData({
    value: txn.eipToSign.message,
    types: txn.eipToSign.types,
    domain: txn.eipToSign.domain
});

Android works as well

Doesn't seem to be related to wallet-core library, converting to a discussion.
