Note: While creating Binance service, pass a currency override array to resolve a currency code difference. This is because Binance chose to use the code BCC for BitcoinCash instead of BCH.

let currencyOverrides = ["BCC": Currency(name: "Bitcoin Cash", code: "BCC")]
let binanceService = Binance.Service(key: key, secret: secret, session: session, userPreference: .USDT_BTC, currencyOverrides: currencyOverrides)

cryptex's Issues

Binance Exchange example, documentation.

@trsathya Hello again. This Cryptex package installs fine using Swift Package Manager 4.

I would like to import Cryptex but would be grateful for an example of how to use the Cryptex package with the Binance exchange.

I'm guessing that I will need to generate an Api Key and Api Secret, but I'm unsure of how to use your module.

Update getAccountBalances method in Kraken to safely unrwarp arrayOfCryptoBalances

Hey,

you should update the getAccountBalances method to this once here and safely unwrap arrayOfCryptoBalances since it will lead to a fatal crash in case a user has once set up the API correctly but then deletes the keys on the website and comes back to the App. This here at least won't lead to the App crashing:

public func getAccountBalances(completion: @escaping (ResponseType) -> Void) {
            let apiType = Kraken.API.getAccountBalance
            if apiType.checkInterval(response: store.balanceResponse) {
                completion(.cached)
            } else {
                krakenDataTaskFor(api: apiType) { (response) in
                    
                    guard let json = response.json as? Dictionary<String, Any> else {
                        print("Error: Cast Failed in \(#function)")
                        return
                    }
                    if let arrayOfCryptoBalances = json["result"] as? Dictionary<String,String> {
                        var balances: [Balance] = []
                        
                        for cryptoBalance in arrayOfCryptoBalances {
                            let newBalance = ["type": cryptoBalance.key,
                                              "amount": cryptoBalance.value,
                                              "available": cryptoBalance.value]
                            
                            balances.append(Balance(json: newBalance, currencyStore: self))
                        }
                        
                        self.store.balances = balances
                        self.store.balanceResponse = response.httpResponse
                        completion(.fetched)
                    }
                }.resume()
            }
        }

Kraken invalid nonce

Hey,

I tried to make a pull request but I can't due to access rights. Kraken has a problem with the nonce, I fixed it on my local branch. You have to change Line 178 in ´Kraken.swift´ from:

let nonce = "\(getTimestampInSeconds())"
postDataDictionary["nonce"] = nonce

to something like this:

let timestamp = NSDate().timeIntervalSince1970
let nonce = "\(Int64(timestamp*1000))"
postDataDictionary["nonce"] = nonce

I assume it has a problem with the format of the nonce, but didn't dig deeper into it, since this fixed it for me.

Best,
Mathias

Problem with retrieving getAccountBalances or getBalances for Kraken

Hey Sathya,

Both functions getAccountBalances and getBalances are failing at the guard statement:
print("Error: Cast Failed in \(#function)")

It seems like that response.json is actually not of the type [[String: String]] but actually gives back an answer. I adjusted the function now to this one here which seems works since I am creating a new Balance object and assign the values, though the rest of the krakenService.store.balances object later is then messed up e.g. ...xxx.currency.code etc. My function:

        public func getAccountBalances(completion: @escaping (ResponseType) -> Void) {
            let apiType = Kraken.API.getAccountBalance
            if apiType.checkInterval(response: store.balanceResponse) {
                completion(.cached)
            } else {
                krakenDataTaskFor(api: apiType) { (response) in
                    
                    guard let json = response.json as? Dictionary<String, Any> else {
                        print("Error: Cast Failed in \(#function)")
                        return
                    }
                    let arrayOfCryptoBalances = json["result"] as! Dictionary<String,String>
                    var balances: [Balance] = []

                    for cryptoBalance in arrayOfCryptoBalances {
                        let newBalance = ["type": cryptoBalance.key,
                                       "amount": cryptoBalance.value,
                                       "available": cryptoBalance.value]
                        
                        balances.append(Balance(json: newBalance, currencyStore: self))
                    }

                    self.store.balances = balances
                    self.store.balanceResponse = response.httpResponse
                    completion(.fetched)
                    }.resume()
            }
        }

Do you want me to create a pull request with my solution or are you taking care of it yourself? Maybe Kraken has updated the API since you wrote it. Also I found it annoying by Kraken that they decided to call most of the crypto currencies with own symbols. e.g. XBT instead of BTC for Bitcoin... is this what your overwrite function is for?

Best,
Matt
