Tried to update to the latest version - 0.2.8 , on building it gives error in the KeystoreV3 class's encryptData function
Am i missing something?
pod 'HDWalletKit'
This is what i have in my podfile.

Hello.
Is there any way to get extended public key using library?

how to get private key as hex and switch test net bitcoin ?

USDT is a BTC token base on omni layer. As HDWallet is support BTC well, so support USDT is easy to implement.
To transfer USDT, we need to construct a transaction base on BTC, so we have two outputs.

1. transfer 546 Satoshi to destination
2. change to change address
3. a OP_RETURN output script to construct the USDT transaction.

Please check the code below:

public struct USDTTransactionBuilder: UtxoTransactionBuilderInterface {
    public init(usdtLockingScript: Data) {
        self.usdtLockingScript = usdtLockingScript
    }
    
    private let usdtLockingScript: Data
    
    public func build(destinations: [(address: Address, amount: UInt64)], utxos: [UnspentTransaction]) throws -> UnsignedTransaction {
        var outputs = try destinations.map { (address: Address, amount: UInt64) -> TransactionOutput in
            guard let lockingScript = Script(address: address)?.data else {
                throw TransactionBuildError.error("Invalid address type")
            }
            return TransactionOutput(value: amount, lockingScript: lockingScript)
        }
        let usdtTxOutput = TransactionOutput(value: 0, lockingScript: usdtLockingScript)
        outputs.append(usdtTxOutput) //add a new script output
        
        let unsignedInputs = utxos.map { TransactionInput(previousOutput: $0.outpoint, signatureScript: $0.output.lockingScript, sequence: UInt32.max) }
        let tx = Transaction(version: 1, inputs: unsignedInputs, outputs: outputs, lockTime: 0)
        return UnsignedTransaction(tx: tx, utxos: utxos)
    }
}

    static func generateUSDTLockingScript(amountInUSDT: Double) -> Data {
       //
        let converter = BitcoinConverter(bitcoinString: "\(amountInUSDT)")
        let amountInSatoshi = converter.inSatoshi
        
        var usdtData = Data()
        usdtData += [0x6a,0x14] //OP_RETURN
        usdtData += [0x6f,0x6d,0x6e,0x69] //OMNI
        usdtData += [0x00,0x00] //Transaction version
        usdtData += [0x00,0x00] // Transaction type
        usdtData += [0x00,0x00,0x00,0x1f] //Currency identifier
        ewLogger.debug("[USDT] amount data=\(amountInSatoshi.littleEndianData.toHexString())")
        usdtData += amountInSatoshi.littleEndianData
        
        return usdtData
    }

I have generated a private key for litecoin for the specific derived path "m/44/2/0/0/0". but private key can not generate same as "https://iancoleman.io/bip39".

different path:

1. m/44/2/0/0/0
2. m/44/2/0/0/1
3. m/44/2/0/0/2 and so on..

Can you please provide a solution to this?

Getting Fatal error: Operation is not supported ios error while generating private key:

Calling:
privateKey = privateKey.derived(at: .hardened(index))

Crashing at:
(mulHi, mulLo) = l.multipliedFullWidth(by: multiplicand)

I tried to look for the issue and found that the issue is related to the architecture of the processor. The library currently supports 64-bit processors and not 32-bit (A6).

During the build an error is generated in scrypt sub-pod:

private func encryptData(password: String, salt: Data, length: Int, N: Int, R: Int, P: Int) -> Data? { guard let passwordData = password.data(using: .utf8)?.sha3(.keccak256) else {return nil} guard let deriver = try? Scrypt(password: [UInt8](passwordData), salt: [UInt8](salt), dkLen: length, N: N, r: R, p: P) else {return nil} guard let result = try? deriver.calculate() else {return nil} return Data(result) }
This method prompts an error: Type of expression is ambiguous without more context

Hello, there. Does hd wallet support segwit address? I can the bech32 implemention from the code? but not ready yet?

I use pod 'HDWalletKit',but find that not have Sign UTXO based transaction

how to fix "unable to open file (in target "HDWalletKit" in project "HDWalletKit")"?

Is there a way to check the particular mnemonic phrase for correctness using your lib?

let mnemonic = Mnemonic.createSeed(mnemonic: "sdfsafsadfasfd")
seems generates a seed anyways without any indication of an error

I tried to sign transaction exactly as in documentation:

func signTransaction() {
        guard let amountString = amountTextField.text else { return }
        guard let address = addressTextField.text else { return }
        let amount = Int((Double(amountString) ?? 0.0) * ethDivident)
        
        let signer = EIP155Signer(chainId: 1)
        let rawTransaction1 = EthereumRawTransaction(
            value: Wei("\(amount)") ?? 0,
            to: "\(address)",
            gasPrice: Int(gasPrice),
            gasLimit: 21000,
            nonce: 2
        )
        guard let signed = try? signer.hash(rawTransaction: rawTransaction1).toHexString() else { return }
        print(signed)
        
        
    }

It's printing transaction hash, but is not substracting any ethereum from the wallet. Also when I check the transaction on Etherium Scan is not showin at all.

let seed = Mnemonic.createSeed(mnemonic: "hazard unable hover gossip impact music country miss end armor addict tissue")
let privateKey = PrivateKey(seed: seed, network: .main(.ethereum))
let purpose = privateKey.derived(at: .hardened(44))
let coinType = purpose.derived(at: .hardened(60))
let account = coinType.derived(at: .hardened(0))
let change = account.derived(at: .notHardened(0))
let firstPrivateKey = change.derived(at: .notHardened(0))
print(firstPrivateKey.publicKey.address) // 0xF8De36ff4fC73528c1C083eC1265e6d6eEF9D82e

Both private and public keys are the same as Coleman, but the address isn't.

Will you support Swift Package Manager?

why not support iOS 10？

After installing HDWalletKit via cocoaPods, my build fails with following error:

HDWalletKit/HDWalletKit/Core/BitcoinScript/Script.swift:455:107: error: 
the compiler is unable to type-check this expression in reasonable time; 
try breaking up the expression into distinct sub-expressions

In development I have fixed this by breaking up mentioned line of code into 2
But now that I want to perform pod lint lib or publish it, it fails
both on my machine and on travis

is it possible to use master public key to generate receive addresses and watch for payments? like a HODL wallet that cannot send?

Hello, there. I tried to build HDWallet via Carthage on xCode 10.1 (10B61) and i get this error ->
I tried also carthage update --platform iOS && carthage update --platform iOS --no-use-binaries but result was the same.
