MIDI Player for iPad/iPhone, written in SWIFT

I am looking for a SWIFT programmer familiar with MIDI file playback and core audio or the audio kit framework on IOS to create a MIDI file player. Audio Kit Framework: [login to view URL] App Description: The MIDI file player will play files that are local on the device and allow the user to adjust tempo, pitch, instruments, volume and toggle tracks on/off using a UI before or during playback. See attachment for further details and specs. Deliverables: The programmer (you) will provide clean/documented code project written in Apple's SWIFT programming language. A sample wireframe screen shot is attached along with the specs. I have also attached three MIDI files which you can use in the XCODE project to test. You can change the UI controls as long as it supports the functionality outlined. Who I will hire / deadline: As for experience, this can be your first UpWork project or you can be a rockstar. I am a developer and don't have the time in my schedule to learn core audio. I would like to see this project completed by the end of June. The project can be started and completed anytime. Thank you for taking the time to look at this posting and I look forward to your proposal.
