My phone is listed as an ineligible target in Xcode and out to the side it says (no paired Apple Watch).
My Apple Watch is registered under iOS Devices. I can see the UDID. The watch has watchOS 2.0 installed and my iPhone 6 has iOS 9 installed. The iPhone pairs just fine with the watch and I can install apps.
I've tried rebooting both the watch and the phone. I've tried rebooting Xcode. I tried creating a new scheme in Xcode but it still shows (no paired Apple Watch). I can choose Product/Destination and the app will show up on the phone, it just won't install the watch app...just sits there saying "Installing...".
I had paired my watch with a new phone and run in to this problem. I removed all files in ~/Library/Developer/Xcode/watchOS DeviceSupport/ and it solved it!
2022, 5 year anniversary: For the past 6 months, I consistently have to sit through one hour of "Preparing Apple Watch for development via iPhone" even when I'm not even debugging a Watch app. Needless to say, this also makes it impossible to run apps on device via Xcode. After about 3 hours (basically half my workday) it starts to work. Once I remove the app for testing, or unplug the iPhone, I have to wait a few hours again. Never in my life have I felt so useless as my job at this point basically consists of watching a loading indicator for hours until the process is done - only for the whole thing still not working most of the time.
Fun fact: Apple on Twitter claims they use the same devices and tools for their Watch apps.
2021: All Quiet on the Western Front. It's been 4 years since my first response. I've now had a good run during December and the first 2 weeks of January. It was so good that I haven't closed the simulator a single time and kept my iPhone connected and never turned off my mac. This worked for 3 weeks but then my iPhone ended up in a boot loop and restoring fails. I bought a new iPhone and now I also can't really connect anymore. See y'all in 2022 :)
2020: At this point I can't even get WCSession to send data on the Simulators anymore. Message from Watch to iPhone with replyHandler works, message from iPhone to Watch fails with WCErrorCodeWatchAppNotInstalled. Every day starts with rebooting numerous times and deleting and setting up new iPhone + Watch combinations. Tried on a freshly installed macOS with my friend's devices and of course no luck. But it's clearly my fault. Submitting a bug report doesn't do anything as they only keep telling you that everything is working on their end and they will close this ticket now. I only wanted to help.
2019: New iPhone, even worse. Now, every single component in my development has changed since 2017 and I'm still stuck targeting the simulator with every build. Apple, why?
2018 II: nothing works for me anymore. Contacted Apple loads of times and Apple Watch seems to have moved to Playground's neighborhood as it's just loading/running but never really running. Bought a second Mac, new project, nothing works. Sad.
2018: The last couple of days I have been really successful doing the following:
On your iPhone:
turn off wifi
turn off bluetooth
turn on wifi
turn on bluetooth
On your Watch:
turn on flight mode
deactivate flight mode
Most of the times it didn't take longer than 30 seconds to get the connection back on track. I think it's the "Watch flight mode"-thing but I never change a (somewhat) running system so this will be my procedure from now on. My 2017-reply still seems to be of help to some people:
2017: If it SOMETIMES shows, and often doesn't, it might be due to the fact that you closed iTunes
I noticed what I often did after reconnecting: closing iTunes. Immediately, the watch turned to be "unpaired". Reconnecting the USB cable but leaving iTunes open has helped me since.
What worked for me is to go to the WatchKit App target and update the Team with the proper account. Once I did that, my device showed as eligible.
Open the camera companion app on the watch. For me this works. Seems like the app starts a phone connection.
It seems that you need to tap on the "Trust this computer" message on Apple Watch. This solved my problem. Also check if XCode displays the message "Indexing..." or "Loading symbols...": you need to wait until the operation is over.
It looks like a bug in Xcode!
Go to ~/Library/Developer/Xcode/watchOS DeviceSupport/ and create a folder named "Watch1,2 2.0 (build number)" and for 'build number' use your watchOS build number. Inside this folder create another folder named "Symbols".
So for the latest build: ~/Library/Developer/Xcode/watchOS DeviceSupport/Watch1,2 2.0 (13S5305d)/Symbols.
Maybe clean & restart Xcode.
For me it was an issue of trusting the computer from the watch. I had to reboot my watch to get the "trust this computer" request.
In my case I believe it was because I had Connect via network enabled for the iPhone that's paired with my new watch.
Upon disabling the wireless connect feature, then connecting the iPhone to my mac via cable, the watch appeared in the Devices list.
After getting the UUID to register with the Developer Center I re-enabled Connect via Network and the watch was no longer listed on the Devices screen. When I connect the phone via cable, however, the watch info appears.
So if you're using wireless connect, try just plugging the device in via cable and hopefully you'll see your watch in the list. Good luck!
I had to delete my Apple ID from the Accounts tab in Xcode preferences and then re-add it.
What worked for me is just waiting for about a minute. There was no progress bar in Xcode, just wait.
For me helped open iTunes at the MAC and leave it open.
Xcode 9.4.1
Check the phone is connected to the same wifi network as the computer.
I've just spent a few days struggling with this, trying the solutions above. Switched networks, waited a minute, now it works again. Gah.
I have four wifi SSIDs in my home (old house, thick walls, one router won't cover it properly) and it turned out the computer was choosing one, and the phone another.
I have the exact same setup and had the same problem. What seemed to work for me was just unpairing and pairing the watch again. Then Trust this computer on the watch and Xcode started to list it in the menu.
It seems that I updated the watchOS2 beta 5 on top of 1.0.1 which was paired earlier and it just needed to be re-set for watchOS2.
What worked for me was to open Xcode's Projects window and click the Delete button next to the Derived Data line for the currently open project. After that, the target automatically switched to show [My iPhone Name] + [My Watch Name].
My setup: Xcode 7, iOS 9 (public release), and watchOS 2 beta.
Open Watch app on device, scroll down to your app, and make sure to enable show app on apple watch
Setting Correct Provisioning profiles | Certificates | Team, then restarting Xcode worked for me.
You must have connected your Apple Watch with you iPhone by bluetooth, wifi connection won´t work for testing...
I really struggled with this problem but this helped me:
Fix steps :
Unpair my watch
Reboot both iPhone and apple watch
Pair them again,and setup my watch as a new one
Plug (unplug first) iPhone to Mac
On apple watch, say Trust the computer when it asks
Unplug and plug again
Close and open XCode
Open the project and wait a few seconds
I may have had a breakthrough....I turned off WIFI on my Mac and it instantly found the watch 😱
This worked for me (Xcode 11.3.1) :
Open Devices from Xcode
Disconnect iPhone from Mac
Disable bluetooth on iPhone
Re-connect iPhone to Mac
Verify iPhone is showing in Devices.
Turn on bluetooth on iPhone, wait to see that watch is connected on iPhone.
Look in Devices -> your iPhone -> Paired watches -> wait for the watch info to completely show.
At this point I was able to see watch in Xcode.
In some cases also needed to restart Watch & Phone as well.
This worked for me
1. Quit Xcode.
2. Disconnect iPhone
3. Remove cache files at /Users//Library/Developer/Xcode
4. Run Xcode.
5. Connect iPhone again
6. Xcode will start to download the symbol file
Just reconnect my iPhone to my Mac is solved my problem. When i reconnect my iPhone, xcode installed itself missed symbols automatically.
I had a similar issue where Xcode was not detecting my paired watch. Somehow, the beta provisioning profile had managed to get installed onto my phone and for some reason Xcode could not detect the paired watch. As soon as I deleted the provisioning profile, Xcode started to pick up the paired watch.
Creating a new watchOS project lead to download of symbols to resume and finish.
I unplugged the iPhone before "Processing symbol files" operation was finished. So Apple Watch never showed up again.
XCode 9 (beta 4). iOS 10 (beta 4). watchOS 2.2.2.
I just waited several minutes and then - it worked by itself.
WatchOS 4.1, XCODE 9.2.
The solution that worked for me with XCode 10.0: trash the whole Xcode folder in ~/Library/Developer/Xcode, removing only the watchOS DeviceSupport was not enough
New update to this issue. I have recently buy the ray wenderlich book for Watch OS and I have had this problem.
After testing a lot of things, and before delete any files, my working solution is this:
On MAC with Xcode open and with the issue scheme loaded. iPhone plugged in and watch turned on too.
1) On MAC turn off wifi
2) On MAC turn on wifi
3) On MAC turn off bluetooth
4) On MAC turn on bluetooth
I know this solution is above, but is the only way it has worked for me. Hope it helps to any dev too.
Check that Bluetooth is enabled. I restarted my Mac, my phone and my watch and that didn't help. When I looked in settings on the watch I found that Bluetooth was disabled.
In my case, rebooting the watch did not work, but after rebooting iPhone it did.
Xcode Version 12.2 (12B45b) seems to fixed all issues regarding the app transfer from your mac to your apple Watch.

I'm working with a fork of this project for Empatica E4 wristbands and I'm unable to make the discover devices work without running the app from Xcode. The situation can be replicated with the original sample project.
When I ran the project through Xcode, I can see the list of nearby devices.
However, when I close the app and ran in from the phone (instead of clicking "play" on Xcode), I can't see any device.
Should I configure something on the Project or own a developer account? Right now I'm not paying a developer account but I thought I could do this without using Xcode to run the app. Thanks.
In short: I can open the app without connecting the phone to XCode but I can't discover devices when I'm not connected to XCode.
More details.
When executed through Xcode on the iphone, the device discover works. On the logs, we can see:
E4tester [didUpdate] status 2 • kBLEStatusScanning
bluetoothd Received XPC message "CBMsgIdScan" from session "Empatica.E4testerCV-central-313-24"
bluetoothd Received 'start scan' request without duplicates for all UUIDs from session "Empatica.E4testerCV-central-313-24"
bluetoothd State of application "Empatica.E4testerCV" is now "foreground-running"
However. When the app is opened on the iPhone (instead of ran via Xcode), we get the following log messages:
E4tester [didUpdate] status 0 • kBLEStatusNotAvailable
E4tester Task <EA813C26-F662-461C-8C47-A97FA7E32BA4>.<0> response ended
E4tester Task <EA813C26-F662-461C-8C47-A97FA7E32BA4>.<0> done using Connection 1
The important detail here is the kBLEStatusNotAvailable status, which contrasts with kBLEStatusScanning. According to their docs this means The iOS device does not support Bluetooth LE, or the Bluetooth LE module is not active. but the device does support BT LE and is enabled.
I opened an issue on their repository.
You need developer's account for testing Xcode apps in devices.
Developer account will give certificates and provisioning to run app in device. There is 2 certificates develop and distribution.
In your case you don't have any apple account. so maybe u are using freee provisioning
Please read this one to understand free provision:
Test iOS app on device without apple developer program or jailbreak
Maybe the capabilites on free provision is limited on debug mode *(runned from xcode)
In the end I got a direct answer from Empatica support team which I think is perfect since I sought an answer from credible and/or official sources.
Still, I would like to thank Antonio for his useful answer as well as Scriptable and Hichem for their messages.
The answer from Empatica E4 team is the following:
#carlosvega If you are working with an iPhone with iOS 11 or 12 you
should add the string NSBluetoothPeripheralUsageDescription in the
Info.plist file. The sample code has been created a while ago before
the privacy string was mandatory.

I developed an app with XCode 8. However, I don't really find any help how to run my app on my own phone. There are just some tutorials for running it on my phone with XCode 7 but those don't really work for me.
Does somebody know how to do that ? Thank you !
Go to http://developer.apple.com and log in with your Apple developer account.
Create a developer certificate
Create an app id for your app
Create a provisioning profile
Download the provisioning profile and import it into Xcode.
Connect your iPhone to your computer. Select your iPhone in Xcode.
Build and run your app.
Or let Xcode do all that for you, since it happens automatically if Xcode is connected to your developer account.
This process is all documented on Apple's developer web site.
AFAIK you just need to:
Start Xcode
Unlock your iPhone
Connect your iPhone to your mac using the Lightning USB cable.
You should be asked (by Xcode) if you want to use the connected phone as a development device.
You can check, if the device is know to Xcode by clicking on Window / Devices. If you connect a device for the first time a little bit of 'magic' is going on that takes a while to complete.
Something like this maybe shown add 'Devices':
I would like to test my app on physical device using Xcode Profile tools but from some reason each device which I connect is marked as offline in Profiler.
What is the approach for making them as accessible to select?
I have:
Xcode 8.1
The first comment is right: after I restarted the device (and only the device, no re-connection was needed, even XCode shouldn't have been restarted), it worked.
I have an enterprise app, that has been installed on about 40 iPads without problems, and suddenly a user comes along with an iPad where the app simply won't install.
I have tried:
Restarting the iPad
Deleting the profiles
Checking restrictions
But so fare without luck
I dont have physical access to the iPad so I cant see any log.
Any suggestions?
It turns out the problem was related to the time on the device. The clock was set 1 hour off.
Check the iPad system version is suitable for your xcode, Check if this device are in your support list, It is device are jailbreak?
I m having xcode 4.5,
I have connected my iTouch(registered in developer program) to Mac Machine. It is appearing in Organizer's Device list. But, it is not appearing in xcode's device list(where simulators are) in one of my project. It is also shown when i open my other proejects.
So, What may be the problem in my this project, in which device is not appearing. Is any settings should be changed??
See the image below and change the settings.
You might need to "trust" the computer - a device will not show up in the organizer if the computer is not trusted.
Restart the iPad while it is connected to the computer. When it restarts, it will ask if you want to "Trust" the computer or not. Do so, then the device will show up in the Xcode Organizer.
Restart XCode
Try Changing the USB Port.
Clean Project. Shift + command + K.
Clear Derive Data.
I tried everything and then found that my device was identified on a different Mac but not mine. Quit and Reopen XCode resolved it.
The deployment target for your project is probably too high (e.g. iOS 7 if you are using Xcode 5 DP). Change it to a minimum version compatible with your device and try again.
Go to organiser, select your device, click on remove button at bottom of organiser screen, unplug your device and connect it once again. That's it. your device should be appear in xcode.
Go to organiser and click your device in the left panel. On the right, see if it is registered for development or not. If not, click "Use for development".
Hope it helps !!
Got this problem too. I plug my phone to Apple Cinema Display. Turns out I forgot to plug in the display's USB cable to my MacBook Air, so only power goes to my device but no data transmission (/me facepalm big time).
My case, I was trying to run a sample app I just downloaded and didn't knew it was iPad only. And I had plugged-in an iPhone. :)
I’m using a MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports) and my iPhone was connected through a USB-C Digital AV Multiport Adapter. The iPhone was no longer shown as a connected device. Tried connecting the iPhone directly to the MacBook without the Adapter and now it IS a connected device. I’m going to consider using a wireless connection for development.
