guard let session = WCSession.from(string: string) else {
// invalid session
// handle session

configure and handle incoming message:

let interactor = WCInteractor(session: session, meta: clientMeta)
interactor.onSessionRequest = { [weak self] (id, peer) in
// ask for user consent
interactor.onDisconnect = { [weak self] (error) in
// handle disconnect
interactor.onEthSign = { [weak self] (id, params) in
// handle eth_sign and personal_sign
interactor.onEthSendTransaction = { [weak self] (id, transaction) in
// handle eth_sendTransaction
interactor.onBnbSign = { [weak self] (id, order) in
// handle bnb_sign

approve session

interactor.approveSession(accounts: accounts, chainId: chainId).done {
print("<== approveSession done")

approve request

interactor.approveRequest(id: id, result: result.hexString).done {
print("<== approveRequest done")

approve binance dex orders

interactor?.approveBnbOrder(id: id, signed: signed).done({ confirm in
print("<== approveBnbOrder", confirm)
