[ios] How do you perform wireless debugging in Xcode 9 with iOS 11, Apple TV 4K, etc?

Wireless debugging was recently added as a feature in Xcode 9, iOS 11, and tvOS 11. Apple TV 4K doesn't have a USB port, so it requires wireless debugging. How do you perform this wireless debugging in Xcode?

This question is related to ios xcode ios11 xcode9

The answer is


Network debugging requires Xcode 9.0 or later running on macOS 10.12.4 or later, and on the device, requires iOS 11.0 or later, or tvOS 11.0 or later.

iPhone

iOS 11 won't be available for 32bit devices, i.e. iPhone 5 and iPhone 5c and below. The first 64bit iPhone is 5s.

iPad

iPad mini 2 will be the oldest iPad with iOS 11 support.

iPod

iPod needs to be an iPod 6 to be able to run iOS.

If you use your devices not only for developing but also for production, be warned that a beta OS is not for the faint hearted ;-)


Step 1 : First time connect phone with Cable

Step 2 : Go to Organizer & Devices

Step 3 : Tick Connect as Network

Now simple trick which works everytime.

Step 4 : Turn on hotspot on iphone

Step 5 : Connect your mac with that hotspot.

Step 6 : Now run the code.

This will always work.


For wireless debugging, Mac system and iPhone/Device should be on same network. For making on same network you can do as - Either you can start hotspot on Mac & connect that on iPhone/Device or vice versa.

On Mac

OR

On iPhone-

enter image description here

Xcode ? Window ? Devices and Simulators ? select devices Tab ? click connect via network enter image description here

Try this:

1) Plug your iOS device into your Mac using a lightning cable. You may need to select to Trust This Computer on your device.

2) Open Xcode and go to Window > Devices and Simulators.

3) Select your device and then select the Connect via network checkbox to pair your device.

4) Run your project after removing your lighting cable.


You can open Xcode Help -> Run and debug -> Network debugging for more info. Hope it helps.


Prerequisite

  • Your Mac Machine should have at least Mac OSX 10.12.4 or later
  • Your iOS device should have at least iOS 11.0 or later
  • Both devices should be on same network.

Steps to Activate

  • Plug your iOS device with Mac machine from cable.

  • Open Xcode then from top menu Window -> Devices and Simulators

  • Chose Devices segment and chose your desired Device from left device list.

  • On right side you can see open Connect via network, enable this option as shown in attached image. Connect via network

  • After few seconds you can see network sign in front of you device. enter image description here

  • Unplug your device and use debugging as you're using normally.

Thanks


LOL, I was doing all the steps here - I ended up doing the unpairing/repairing steps from the "given by Surjeet" answer. It didn't work, and then I noticed that when I clicked the "connect via network" button, the same yellow box would pop up that pops up when you repair, saying "busy" - I got frustrated and just started hammering the "connect via network" button, clicking it quickly for probably like 15 - 20 clicks - it started spazzing out, but eventually landed on being able to connect to the network. Before that worked, I also shut my wifi off and turned it on again, as suggested by one of these answers, but clicking the "connect via network" button really fast did the trick...LOL

Also, before I hammered the button, I linked the device support folders, although I'm not sure if it did anything:

open the terminal

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

ln -s 13.3 13.4

ls -l 13.4

restart Xcode and retry run on device

Said to do it here - https://forums.developer.apple.com/thread/126940 - I edited the folder version in my comment to adjust to the latest version of iOS 13.4.

EDIT I believe I figured out what my problem was, I had to stop my Little Snitch network filter. Also, after I was able to connect by hammering the button, the "connect via IP address" option appeared in the dropdown when you right click on the device in the devices manager in xcode, it wasn't there before I was able to connect ultra-hacky style the first time. If I connect, and then turn my network filter on, it disconnects my phone.


In the new Xcode9-beta, we can use wireless debugging as said by Apple:

Cut the Cord
Choose any of your iOS or tvOS devices on the local network to install, run, and debug your apps – without a USB cord plugged into your Mac. Simply click the ‘Connect via Network’ checkbox the first time you use a new iOS device, and that device will be available over the network from that point forward. Wireless development also works in other apps, including Instruments, Accessibility Inspector, Quicktime Player, and Console.

Try this!

If facing disconnection issues, try this:

Workaround: Enable airplane mode on your device for 10 seconds and then disable airplane mode to re-establish your connection


i followed all the suggested steps, in particular the ones provided from ios_dev but my iPhone was not recognized from Xcode and i was not able to debug over WiFi. Right click on the left panel over my iDevice in "Devices and Simulators" window, then "Connect via IP Address...", inserted the iPhone IP and now it correctly works


The only way I could get it to work is if my Mac and my iPhone were on different networks. I have a main DSL modem call it network1 and a second network2 setup us an access point. They have SSIDs network1 and network2. If the phone was on network1 and the mac on network2 it would work, or vice versa. But if both were on network1 or both were on network2, it would NOT work.


The only thing that worked for me was to connect my phone to my MacBook using Bluetooth. (I did this after first pairing my phone with Xcode while connected via cable per ios_dev's answer above.)

On my phone, I went to Settings > Bluetooth and tapped my MacBook's name under "MY DEVICES" to connect.

I then went to Xcode > Devices and Simulators, selected my phone and checked "Connect via network". After a few seconds, the globe icon appeared next to my phone and I could run and debug my app on my phone.

This worked even when my MacBook was connected to a WiFi network and my phone was using LTE. The only downside is that it was quite slow installing the app to the phone.


I just talked to some Xcode engineers at WWDC and the auto discovery of iDevices is still a little buggy. Also sometimes your phone is not correctly broadcasting. Switching your device on and off can help.

There are a few workarounds/fallbacks:

You can check if your phone is broadcasting with Bonjour Browser (www.tildesoft.com). Look if your wifi address is listed under the service called '_apple-mobdev2._tcp. - 215' (you can find your wifi address here: settings > general > about > wifi address.

As a fallback you can connect to your device by manually entering the IP address (right click on your devices in the Devices window). However this IP address will be persisted, so if you change networks you'll need to reset this. That option is not available in Xcode yet, but you can do it via the terminal with the following command:

defaults read com.apple.dt.Xcode | grep IDEIDS

This will print an identifier which you need to use in the next command:

defaults delete com.apple.dt.Xcode <identifier>

Now the ip address is cleared and you can enter a new one.

The last option is to create a computer-to-computer network. This works fine, but logically you won't have internet access then.

My problem was about network SSID broadcasting.

I've tried all the solutions above but still couldn't connect my device, there was no 'globe' icon for my device at all. Then I found that for some reason my network had turned its SSID broadcasting off(tho I could still connect the network by inputing the SSID manually). Once I turned the SSID broadcasting on, I could connect my device via 'Connect via IP Address...'.


Enable Internet Sharing using USB ports:

I tried all answers but nothing worked for me. I ended up connecting to different WiFi network then I was able to debug wirelessly.

I have no clue why it didn't work with the old network


I have tried using Xcode Devices window's Connect via network options. but I am unable to see the "Connected over the network" icon next to the device name. also as soon as remove the USB the "Connect via network" option disappeared. also, the device name appears under the disconnected device list.

But using the "Connect via IP Address..." option, I am able to connect.

  1. Right-click on the device name(Under Disconnected list) and choose "Connect via IP Address...." option.

enter image description here

  1. Type the IP address of the device and chose Connect. (you can find through mobile device Settings > Wi-Fi > Choose the wifi name) enter image description here

If after following the steps as described by Surjeet you still can't connect, try turning your computer's Wi-Fi off and on again. This worked for me.

Also, be sure to trust the developer certificate on the iOS device (Settings - General - Profiles & Device Management - Developer App).


If you have completed all steps given by Surjeet and still not getting network connection icon then follow below steps:

  1. Unpair Device using right click on the device from the Connected section.

    enter image description here

  2. Reconnect the device.

  3. Click on "+" button from the end of the lefthand side of the popup.

enter image description here

  1. Select the device and click on next button

enter image description here

  1. Click on Trust and passcode(if available) from the device.

enter image description here

  1. Click on Done button.

enter image description here

  1. Now, click on connect via network.

enter image description here

Now you can see the network connection icon after the device name. Enjoy!
