Blockchain_SDK_iOS

BlockChain SDK iOS aims to provide simple & intuitive interface for iOS apps to access various blockchains. The code is in Swift and generated based on the OpenRPC specifications.

Usage

Import the package

import Blockchain_SDK_iOS

Configure endpoint

HTTP

let configuration = Eth.Configuration(rpcConfiguration: .init(baseURL: URL(string: "https://eth-mainnet.alchemyapi.io/v2/...")!))
let eth = try Eth(configuration: configuration)

Web socket

let config = Eth.Configuration(websocketConfiguration: .init(baseURL: URL(string: "wss://eth-mainnet.alchemyapi.io/v2/...")!))
let eth = try Eth(configuration: config)

Call method & get response

HTTP

Via asyn method

let result = try await eth.eth_getBlockByHash(blockHash: "0x9e3b33ba48d2cec5314886e03bf205ec873e2a1171311d1534eaba6fbbcbe303", hydratedTransactions: true)

Via combine subscription

try eth.eth_getBlockByHash(blockHash: "0xfa4f674587a6f836de096f12b0f9612d4d2fa7f7f6c94db3acc06dbda8ff61cc",
                           hydratedTransactions: true)
.sink { completion in
    print(completion)
} receiveValue: { value in
    print(value)
}.store(in: &cancellables)

Web socket

Connect

eth.connectWebSocket()

Monitor connection status

eth.webSocketStatusPublisher
    .receive(on: RunLoop.main)
    .sink { value in
        print(value)
    }.store(in: &cancellables)

Send out request

try eth.eth_getBlockByHash(blockHash: "0xfa4f674587a6f836de096f12b0f9612d4d2fa7f7f6c94db3acc06dbda8ff61cc",
                           hydratedTransactions: true,
                           id: 1)

Monitor response

eth.webSocketResultPublisher
.sink { value in
    print(value)
}.store(in: &cancellables)

Disconnect

eth.disconnectWebSocket()
