Mobile development

I need an iPhone app. I would like it designed and built. Hi, I’m looking for an expert iOS (swift native) developer with knowledge of cryptocurrencies trading to code the app below Tweet trader iOS app Log in to your twitter profile Follow/unfollow people from twitter app, no need to have functionality in the app Every x minutes (setup in settings) Parse tweets from people you follow (not retweets) When a string matches a coin identifier or a name of a coin available from one of the supported exchanges (get a list of coins , three letters code and full name on launch ... Btc bitcoin, eth ethereum from each supported exchange) , display a notification on the phone , once clicked (expire old notifications after x minutes ) setup a market buy order (fill or kill) for x btc (x can be defaulted for each exchange in the settings) also add buttons for standard quantities if you want to override the default (10,20,30,50% of btc balance on that exchange but also 0.1,0.2,0.5,1,1.5,2,2.5,5 btc), on the same setup window show balance of btc and the coin being traded , show graph with 1 5 30 1d intervals (default to 1min), user has to press execute button to send order to the market (give option to close the proposed order if you don’t want to trade it ) Also if enabled in the settings once the buy is fully executed , auto setup a market sell for x%gain (auto sell all of the available quantity when price reaches buy price +x% (if enabled, this is automatically sent to the market) Handle multiple concurrent tweets, create like a queue of proposed order so the user can go trough them one by one Filter strings in settings if you don’t want to trade specific coins (ignore xrp, ignore ripple and so on) Add settings for twitter api and crypto api (stored locally on device) Supported Exchanges Bittrex Will add poloniex and others in v2 Master switch for each exchange to stop the bot
