Lisk Swift

Lisk Swift is a Swift 4 library for Lisk - the cryptocurrency and blockchain application platform. It allows developers to create offline transactions and broadcast them onto the network. It also allows developers to interact with the core Lisk API, for retrieval of collections and single records of data located on the Lisk blockchain. Its main benefit is that it does not require a locally installed Lisk node, and instead utilizes the existing peers on the network. It can be used on any environment that runs Swift 4, including iOS, tvOS, macOS, watchOS.

Lisk Swift is heavily inspired by Lisk JS

Usage

Import Framework

import Lisk

Send LSK

let address = ...
let secret = ...

// Send LSK on the Mainnet
Transactions().transfer(lsk: 1.12, to: address, secret: secret) { response in
    switch response {
    case .success(let result):
        print(result.transactionId)
    case .error(let error):
        print(error.message)
    }
}

Send LSK on Testnet

let address = ...
let secret = ...

// Send LSK on the Testnet
Transactions(client: .testnet).transfer(lsk: 1.12, to: address, secret: secret) { response in
    switch response {
    case .success(let result):
        print(result.transactionId)
    case .error(let error):
        print(error.message)
    }
}

Testnet

By default, all modules are initialized with an APIClient pointing to the Lisk Mainnet. You can optionally pass in a specific client to any modules constructor:

let mainTransactions = Transactions()
let testTransactions = Transactions(client: .testnet)

To default all modules to a specific client you can set the shared client:

APIClient.shared = .testnet

And then all modules initialized will default to Testnet:

// This will connect to Testnet
let transactions = Transactions()

Requirements

• iOS 10.0+ / macOS 10.12+ / tvOS 10.0+ / watchOS 3.0+
• Xcode 9.0+
• Swift 4.0+
