I am trying to establish a remote connection to an iOS 11 device for debugging. Both devices are on the same Wi-Fi network, I'm using Xcode 9 and in Window->Devices and Simulators have checked the "Connect via network" box. I do not get a network icon next to my device, nor do I get any prompt on the device itself.The application if for point of sale and the Wi-Fi firewall has most ports blocked. For example, I know port 22 (ssh) is blocked - the only open port I'm certain of is 8080. I suspect the port used for debugging is blocked. What port(s) are used for debugging? I can request the network guys open a few ports if needed.

We have not been able to reliably recreate this situation, but sometimes our UIBarbuttonItems (in a UIToolbar) appear to be disabled - i.e., it has a "greyed out" appearance. The buttons ARE enabled - if you tap them their action is invoked.Has anyone seen this behavior?
