One-click Auth getting error "Signature verification failed"

[tuonght93]

Describe the bug
Follow document: https://docs.reown.com/walletkit/ios/one-click-auth
`let sessionAuthenticate = sessionAuthenticateMap[id]
guard let sessionAuthenticate = sessionAuthenticate else {
reject("", "", NSError(domain: "", code: 0))
return
}

    let requestedChains = Set(sessionAuthenticate.payload.chains.compactMap { Blockchain($0) })
    let supportedChains = Set(chains.compactMap{Blockchain($0)})
    let commonChains = requestedChains.intersection(supportedChains)
    let supportedMethods = [
      "personal_sign"
    ]
    
    var authObjects = [AuthObject]()
    
    for chain in commonChains {
      let accountForChain = Account("\(chain):\(address)")!
      let supportedAuthPayload = try WalletKit.instance.buildAuthPayload(
          payload: sessionAuthenticate.payload,
          supportedEVMChains: Array(supportedChains),
          supportedMethods: supportedMethods
      )
      let formattedMessage = try WalletKit.instance.formatAuthMessage(payload: supportedAuthPayload, account: accountForChain)
      let signature = try messageSigner.sign(message: formattedMessage, privateKey: Data(hex: privateKey), type: .eip191)

      let authObject = try WalletKit.instance.buildSignedAuthObject(
          authPayload: supportedAuthPayload,
          signature: signature,
          account: accountForChain
      )
      authObjects.append(authObject)
    }
    
    let session = try await WalletKit.instance.approveSessionAuthenticate(requestId: sessionAuthenticate.id, auths: authObjects)
    if(session != nil) {
      print(session!)
    }`

I follow a document but getting error when approveSessionAuthenticate. I don't know what is the problem with signature.
