移动端DApp使用WalletConnect v2连接Trust Wallet失败求助

问题背景 #

移动端应用原本使用WalletConnect SDK v1连接MetaMask钱包，验证连接及用户登录功能正常。现计划升级至WalletConnect SDK v2，但MetaMask暂不支持该版本，因此尝试连接Trust Wallet。参考WalletConnectSwift库及官方文档集成后，通过代码生成URI可跳转至Trust Wallet，但钱包未显示验证界面，始终提示“WalletConnect会话已断开”（错误截图：）。

核心代码示例 #

创建连接请求代码 #

let namespaces: [String: ProposalNamespace] = [
    "eip155": ProposalNamespace(
        chains: [
            Blockchain("eip155:137")!,
            Blockchain("eip155:1")!
        ],
        methods: ["personal_sign"], events: ["accountsChanged", "chainChanged"]
    )
]

Task {
    let uri = try await Pair.instance.create()
    try await Sign.instance.connect(
        requiredNamespaces: namespaces,
        topic: uri.topic
    )
    await showConnectScreen(uri: uri)
}

跳转钱包代码 #

func showConnectScreen(uri: WalletConnectURI) async {
    let url = URL(string: "https://link.trustwallet.com/wc?uri=\(uri.absoluteString)")!
    // 也曾尝试使用官方链接
    // let url = URL(string: "https://walletconnect.com/wc?uri=\(uri.absoluteString)")!
    DispatchQueue.main.async {
        UIApplication.shared.open(url, options: [:]) { [weak self] _ in
            self?.dismiss(animated: true, completion: nil)
        }
    }
}

已配置但未触发的监听回调 #

Sign.instance.sessionDeletePublisher
    .receive(on: DispatchQueue.main)
    .sink {  _ in
        print("showSelectChainScreen")
    }.store(in: &publishers)

Sign.instance.sessionResponsePublisher
    .receive(on: DispatchQueue.main)
    .sink {  response in
    }.store(in: &publishers)

Sign.instance.sessionSettlePublisher
    .receive(on: DispatchQueue.main)
    .sink { [unowned self] session in
        print("session: \(session)")
    }.store(in: &publishers)

补充信息 #

测试发现浏览器端Pancakeswap可正常连接多个钱包并完成验证，需解决移动端应用连接Trust Wallet或其他WalletConnect v2兼容钱包的问题。
