Area: AVFoundation (Audio / Video) Summary: Calling [[MIDINetworkSession defaultSession] addConnection:connection] seems to have no effect on iOS 10. While [MIDINetworkSession defaultSession].connections subsequently does return the given connection, no network MIDI messages are exchanged. While testing with my Mac (running 10.11.6 (15G1004)), I found the only way to make a connection was to do it from Audio MIDI Setup on the Mac. Steps to Reproduce: 1. Call [[MIDINetworkSession defaultSession] addConnection:connection], with a valid host Expected Results: Connection is made, [[MIDINetworkSession defaultSession] addConnection:connection] returns array including new connection, and network MIDI messages can be exchanged Actual Results: [[MIDINetworkSession defaultSession] addConnection:connection] returns array including new connection, but no connection is actually made. This can be verified by trying to exchange MIDI messages, or by checking the "Participants" list in Audio MIDI Setup. Version: iOS 10.0.1 (14A403) Notes: This works fine on an iPad Mini Retina running iOS 9.3.5 (13G36). Configuration: Reproduced with iPhone 6S Plus and iPad Air 2 Attachments:
