Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding TronWeb as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/james19870606/TronWeb.git", .upToNextMajor(from: "1.1.6"))
]

Example usage in CocoaPods

import TronWeb   

Example usage in Swift Package Manager

import TronWeb3   

Setup TronWeb3

let tronWeb = TronWeb3()
let privateKey = ""
let TRONApiKey = ""
if tronWeb.isGenerateTronWebInstanceSuccess != true {
    tronWeb.setup(privateKey: privateKey, node: chainType == .main ? TRONMainNet : TRONNileNet) { [weak self] setupResult,error in
        guard let self = self else { return }
        if setupResult {
        //......
        } else { 
          print(error)
        }
    }
} else {
        //......

}

Create Random

tronWeb.createRandom { [weak self] state, address, privateKey, publicKey, mnemonic, error in
    guard let self = self else { return }
    self.createRandomBtn.isEnabled = true
    tipLabel.text = "create finished."
    if state {
        let text =
            "address: " + address + "\n\n" +
            "mnemonic: " + mnemonic + "\n\n" +
            "privateKey: " + privateKey + "\n\n" +
            "publicKey: " + publicKey
        walletDetailTextView.text = text
    } else {
        walletDetailTextView.text = error
    }
}

Create Account

tronWeb.createAccount { [weak self] state, base58Address, hexAddress, privateKey, publicKey, error in
    guard let self = self else { return }
    self.createAccountBtn.isEnabled = true
    tipLabel.text = "create finished."
    if state {
        let text =
            "base58Address: " + base58Address + "\n\n" +
            "hexAddress: " + hexAddress + "\n\n" +
            "privateKey: " + privateKey + "\n\n" +
            "publicKey: " + publicKey
        walletDetailTextView.text = text
    } else {
        walletDetailTextView.text = error
    }
}

Import Account From Mnemonic

tronWeb.importAccountFromMnemonic (mnemonic: mnemonic){ [weak self] state, address, privateKey, publicKey, error in
    guard let self = self else { return }
    self.importAccountFromMnemonicBtn.isEnabled = true
    tipLabel.text = "import finished."
    if state {
        let text =
            "address: " + address + "\n\n" +
            "privateKey: " + privateKey + "\n\n" +
            "publicKey: " + publicKey
        walletDetailTextView.text = text
    } else {
        walletDetailTextView.text = error
    }
}

Send TRX

let remark = ""
let toAddress = ""
let amountText = "1" // This value is 0.000001 
tronWeb.trxTransferWithRemark(remark: remark,
                                      toAddress: toAddress,
                                      amount: amountText){ [weak self] (state, txid,error) in
    guard let self = self else { return }
    print("state = \(state)")
    print("txid = \(txid)")
    if (state) {
        self.hashLabel.text = txid
    } else {
        self.hashLabel.text = error
    }
}

Send TRC20

let remark = ""
let toAddress = ""
let amountText = "1" // This value is 0.000001 
let trc20Address = ""
tronWeb.trc20TokenTransfer(toAddress: toAddress,
                           trc20ContractAddress: trc20Address, amount: amountText,
                           remark: remark,
                           feeLimit: "100000000") { [weak self] (state, txid,error) in
    guard let self = self else { return }
    print("state = \(state)")
    print("txid = \(txid)")
    if (state) {
        self.hashLabel.text = txid
    } else {
        self.hashLabel.text = error
    }
}

Estimate Fee when Send TRC20

let toAddress = ""
let amountText = amountTextField.text
let trc20Address = self.trc20AddressTextField.text 
tronWeb.estimateEnergy(url:chainType == .main ? TRONMainNet : TRONNileNet, toAddress: toAddress, trc20ContractAddress: trc20Address, amount: amountText) { (state,feeDic,error) in
        if state {
              /*
                feeDic =     {
                    energyFee = 420;
                    "energy_used" = 4146;
                    feeLimit = "1.74132";
                };
               */
        } else {
