Error Initializing with Wallet Connect (dApp -> Rainbow Wallet)

[zkhalapyan]

Describe the bug
Redirecting the user to Rainbow Wallet and getting an error "Error Initializing Wallet Connect".

SDK Version

• Client: Swift / iOS
• Version: main

To Reproduce

The code runs directly inside AppDelegate in a SwiftUI app:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
    let metadata = AppMetadata(name: "Example",
                               description: "The best of the best.",
                               url:"example.come",
                               icons:[])
    let client = WalletConnectClient(metadata: metadata,
                                     projectId: "607d02fd15dee0875944ded71bab8ce0",
                                     isController: false,
                                     relayHost: "wss://relay.walletconnect.com");
    let connectParams = ConnectParams(
        permissions: SessionType.Permissions(
            blockchain: SessionType.Blockchain(chains: ["eip155:1"]),
            jsonrpc: SessionType.JSONRPC(methods: ["eth_sendTransaction", "personal_sign", "eth_signTypedData"]),
            notifications: SessionType.Notifications(types: [""])))
    
    do {
        if let uri = try client.connect(params: connectParams), let url = URL(string: uri) {
            if (UIApplication.shared.canOpenURL(url)) {
                print(uri)
                DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
                    UIApplication.shared.open(url, options: [:], completionHandler: nil)
                }
                
            }
        }
    } catch {
        print("[PROPOSER] Pairing connect error: \(error)")
    }
    
    client.delegate = self;
    return true
}

Expected behavior
For Rainbow wallet to ask if it's ok to connect.

I tired to look into system logs while doing the redirection from my app to Rainbow, but couldn't find anything interesting. Any advice on how I could debug this?

hey @zkhalapyan, it does not look like recent version but something very old. Could you try v0.8.1-beta.102?

[zkhalapyan]

ok, I am definitely using old code, see migration guide here.

The only problem is that the new version has import issues: #329

😢

[zkhalapyan]

Also, doesn't seem like Rainbow is supporting V2; you can take a look at the app directory here to see which apps support the newest version!

@zkhalapyan I think we have the same issue in our project. Have you found any workarounds?

[shles]

found a solution here WalletConnect/WalletConnectSwift#68 (comment)

[zkhalapyan]

@shles the code above is outdated and Rainbow doesn't even support V2. I guess the solution you see is from people reverse engineering their deep link?

Regardless, checkout the task here: #329

Pretty much if you try to install WalletConnectSwiftV2, you get the wrong package lol 🤦‍♂️
