Swift JSON-RPC client for Factom API

A JSON-RPC Swift client for the Factom protocol. Each response has unique type that automatically converted from JSON response and suitable for further usage in business logic. All responses are available in Response directory along with convinient converters.

Implementation

clone this repo on your project root path
git clone https://github.com/kompendium-llc/factom-swift-client.git

Config

You can change default node url or ports
import factoms_swift
let config = Config.init(host: "http://abc.com", port: "8000", walletdPort: "8009")

Usage

We list several examples to provide better understanding on how to use library within your codebase.

Retreiving a balance

    import factoms_swift
    self.factomd = FactomdService.init(config: config)

    /// get ec address balance
    self.factomd.entryCreditBalance(address: "EC2dTBH2Nc9t9Y7RFD3FYMN5ottoPeHdk6xqUWEc6eHVoBPj6CmH")
    { (response, error) in
        if response != nil
        {
        if let result = response!["result"] as? JSONObject {
            if let balance = result["balance"]
            {
                print(balance)
            }
        }else
        {
           print(error!.localizedDescription)
        }
    }

Writing an Entry

    import factoms_swift
    self.factomd = FactomdService.init(config: config)

    //commit entry
        self.factomd.commitChain(message: "00015507b2f70bd0165d9fa19a28cfaafb6bc82f538955a98c7b7e60d79fbf92655c1bff1c76466cb3bc3f3cc68d8b2c111f4f24c88d9c031b4124395c940e5e2c5ea496e8aaa2f5c956749fc3eba4acc60fd485fb100e601070a44fcce54ff358d606698547340b3b6a27bcceb6a42d62a3a8d02a6f0d73653215771de243a63ac048a18b59da2946c901273e616bdbb166c535b26d0d446bc69b22c887c534297c7d01b2ac120237086112b5ef34fc6474e5e941d60aa054b465d4d770d7f850169170ef39150b") { (response, error) in
            if response != nil {
                if let result = response!["result"] as? JSONObject {
                    if let txid = result["txid"]
                    {
                        print(txid)
                    }
                }
                }else
                {
                print(error!.localizedDescription)
            }
        }

    // reveal chain
        self.factomd.revialChain(entry: "007E18CCC911F057FB111C7570778F6FDC51E189F35A6E6DA683EC2A264443531F000E0005746573745A0005746573745A48656C6C6F20466163746F6D21") { (response, error) in
            if response != nil {
                if let result = response!["result"] as? JSONObject {
                    if let chainid = result["chainid"] {
                        print(chainid)
                    }
                }
            }else
            {
                print(error!.localizedDescription)
            }
        }

Block Height and Current Minute

    import factoms_swift
    self.factomd = FactomdService.init(config: config)

    //fblockByHeight
        self.factomd.heights { (response, error) in
            if response != nil {
                if let result = response!["result"] as? JSONObject {
                    if let directoryblockheight = result["directoryblockheight"] {
                        print(directoryblockheight)
                    }
                }
            }else
            {
                print(error!.localizedDescription)
            }
        }

    //get current minute
        self.factomd.currentTime { (response, error) in
            if response != nil {
                if let result = response!["result"] as? JSONObject {
                    if let leaderheight = result["leaderheight"] {
                        print(leaderheight)
                    }
                }
            }else
            {
                print(error!.localizedDescription)
            }
        }

Getting transaction

    import factoms_swift
    self.factomd = FactomdService.init(config: config)

    /// get transaction list
        self.factomd.pendingTransactions(address: "FA2jK2HcLnRdS94dEcU27rF3meoJfpUcZPSinpb7AwQvPRY6RL1Q") { (response, error) in
            if response != nil {
                if let result = response!["result"] as? JSONObject {
                    if let transactionid = result["transactionid"] {
                        print(transactionid)
                    }
                }
            }else
            {
                print(error!.localizedDescription)
            }
        }

        /// get transaction
        self.factomd.transaction(hash: "64251aa63e011f803c883acf2342d784b405afa59e24d9c5506c84f6c91bf18b") { (response, error) in
            if response != nil {
                if let result = response!["result"] as? JSONObject {
                    if let factoidtransaction = result["factoidtransaction"] as? JSONObject {
                        if let millitimestamp = factoidtransaction["millitimestamp"] {
                            print(millitimestamp)
                        }
                    }
                }
            }else{
                print(error!.localizedDescription)
