neo-swift

Swift SDK for the NEO blockchain.

What is neo-swift

A swift client for interacting with a node on the NEO blockchain.
Written in Swift4 and using Xcode9 Beta
Primarily meant to be the SDK for iOS and macOS wallet software.
Underlying cryptographic methods compiled into frameworks via go-mobile.
iOS framework
underlying go code

Current Status

Implements read operations of neo blockchain
Allows for send asset transactions
This is pre-alpha software meant only to be used by experienced developers, use at your own risk

Supported Methods

    enum RPCMethod: String {
        case getBestBlockHash = "getbestblockhash"
        case getBlock = "getblock"
        case getBlockCount = "getblockcount"
        case getBlockHash = "getblockhash"
        case getConnectionCount = "getconnectioncount"
        case getTransaction = "getrawtransaction"
        case getTransactionOutput = "gettxout"
        case getUnconfirmedTransactions = "getrawmempool"
        case sendTransaction = "sendrawtransaction"
        //The following routes can't be invoked by calling an RPC server
        //We must use the wrapper for the nodes made by COZ
        case getBalance = "getbalance"
    }

Things in the pipleine

Quick Start

Clone the repo and open the project in xcode and run all tests in NeoSwiftTests.swift

Example Usage

func demo() {
  // Create an account via a wif string
  let wifPersonA = "L4Ns4Uh4WegsHxgDG49hohAYxuhj41hhxG6owjjTWg95GSrRRbLL" // REMINDER TO NEVER USE THIS FOR REAL FUNDS
  let wifPersonB = "L4sSGSGh15dtocMMSYS115fhZEVN9UuETWDjgGKu2JDu59yncyVf" // REMINDER TO NEVER USE THIS FOR REAL FUNDS
  let accountA = Account(wif: wifPersonA)
  let accountB = Account(wif: wifPersonB)
  print(accountA.wif)
  print(accountA.publicKeyString)
  print(accountA.privateKeyString)
  print(accountA.address)
  print(accountA.hashedSignature) //Data

  accountA.sendAssetTransaction(asset: .gasAssetId, amount: 1, toAddress: accountB.address) { success, error in
            assert(success ?? false)
  }
}

Dynamic framework

If you are linking NeoSwift as a Dynamic framework. Create a new “Run Script Phase” in your app’s target’s “Build Phases” and paste the following snippet in the script text field:

bash "${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/NeoSwift.framework/strip-frameworks.sh"

This step is required to work around an App Store submission bug when archiving universal binaries.
