Introduction

Overview

SwiftyArk is a simple, lightweight framework for the Ark Ecosystem. SwiftyArk provides a simple wrapper for accessing Ark accounts, delegates, block, and transaction information.

SwiftyArk's networking component is fully asynchronous and have extensive error handling. SwiftyArk data structures are type-safe and favor immutability.

Requirements

iOS 8.0+
mac OSX 10.10+
Swift 3.0

Getting Started:

The Ark APi is accessed with the ArkManager:

let manager = ArkManager()

ArkManager handles all network calls and returns results asynchronous in a closure:

manager.delegates { (error, delegates) in
   if let arkError = error {
        print(arkError.localizedDescription)
           return
    }

    if let currentDelegates = delegates {
    	// List of delegates
     }
}

With the manager instance, you can access an account:

manager.account(address: "AUexKjGtgsSpVzPLs6jNMM6vJ6znEVTQWK") { (error, arkAccount) in
  if let account = arkAccount {
       // Account(address: "AUexKjGtgsSpVzPLs6jNMM6vJ6znEVTQWK",
       // unconfirmedBalance: 16118512.398923151,
       // balance: 16118512.398923151,
       // publicKey: "02ff171adaef486b7db9fc160b28433d20cf43163d56fd28fee72145f0d5219a4b",
       // unconfirmedSignature: Optional(0),
       // secondSignature: Optional(0),
       // multisignatures: Optional([]),
       // secondPublicKey: nil,
       // unconfirmedMultisignatures: Optional([]))
   }
}

The manager instance can store a session for easy accessing of an address/delegate:

manager.delegate("jarunik") { (error, delegate) in
   if let arkDelegate = delegate {
		// Delegate(username: "jarunik", 
		// address: "Aasu14aTs9ipZdy1FMv7ay1Vqn3jPskA8t", 
		// publicKey: "02c7455bebeadde04728441e0f57f82f972155c088252bf7c1365eb0dc84fbf5de",
		// votes: 1246983.70585494,
		// producedblocks: 
		// 28670, 
		// missedblocks: 61, 
		// rate: 47, 
		// approval: 0.970000029, 
		// productivity: 99.7900009)
       // Update the session settings with delegate
       manager.updateSettings(delegate: arkDelegate)
   }
}

With the stored session credentials, you can easily access acccount information:

 manager.lastBlock { (error, block) in
    if let lastBlock = block {
    	 // Block(id: "3725283905614253778",
    	 // version: 0,
    	 // timestamp: 2017-09-19 00:48:48 +0000,
    	 // height: 1948928,
    	 // previousBlock: "17490567348134875423",
    	 // numberOfTransactions: 0,
    	 // totalAmount: 0.0,
    	 // totalFee: 0.0,
    	 // reward: 2.0,
    	 // payloadLength: 0,
    	 // payloadHash: "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855",
    	 // generatorPublicKey: "#{key}",
    	 // generatorId: "ARAq9nhjCxwpWnGKDgxveAJSijNG8Y6dFQ",
    	 // blockSignature: "#{signature}",
    	 // confirmations: 27,
    	 // totalForged: 2.0)
    }
 }

SwiftyArk supports creating and sending new transactions:

 manager.sendTransaction("recipientAddress", amount: 100.0, passphrase: "passphrase", secondPassphrase: "secondPassphrase", vendorField: "my message") { (error, response) in
     // response
}

With SwiftyArk, you can also vote/unvote for a delegate:

manager.delegate("jarunik") { (error, delegate) in
    if let jarunik = delegate {
        manager.sendVote(jarunik, passphrase: "passphrase", secondPassphrase: "optionalSecondPassphrase") { (error, response) in
        	// response
        }
    }
}

SwiftyArk also has a built in Ark Ticker provided by CoinMarketCap with support for 31 currencies:

manager.ticker(currency: .cad) { (error, ticker) in
   if let canadianTicker = ticker {
        // Ticker(currency: SwiftyArk.Currency.cad,
        // id: "ark",
        // name: "Ark",
        // symbol: "ARK",
        // rank: 20,
        // price: 4.3638476501000003,
        // bitcoinPrice: 0.00088648999999999998,
        // volume24Hour: 5406421.2865599999,
        // marketCap: 426120847.0,
        // availableSupply: 97647966.0,
        // totalSupply: 128897966.0,
        // percentChange1h: -3.7999999999999998,
        // percentChange24h: 1.8700000000000001,
        // percentChange7d: -1.1100000000000001)
   }
}
