Clash Royale CLAN TAG#URR8PPPXcode “Device Locked” When iPhone is unlocked
When I tried to build and run, Xcode said my device was locked. I looked at my iPhone, and it's not locked at all....possible bug? How do I fix this?
tried it, still no luck

For me, unplugging and re-plugging did the trick. No need to Clean Build Folder, restart Mac with Command+Option+P+R, leave the house and come back again, burn a Voodoo doll of Steve Jobs, etc.

Did you by chance not "trust" the device? This will prevent it from communicating with xcode even if the device is unlocked.
Update here's a support doc from Apple: http://support.apple.com/en-us/HT5868
I'm not sure what you mean by "trust"...how do i enable that?

Unplug the device, close xcode, and then open xcode and plugin the device. When you plug it in (after unlocking it) it you should be prompted to "trust" the computer (in the iOS device). My guess is you may have accidentally tapped "do not trust" and so the device will refuse to connect to the computer.

I've updated the answer with a link to apple support page regarding the issue.

This is really weird because in my case, I was never prompted to trust in the first place...

@NicolasMiari I've had other notifications show up at the same time I plug in my phone causing it disappear, or accidentally dismissing the prompt on my Mac... as well, if you've used mobile configurator there is a chance it's causing some weird issues as the device could be configured to only respond to one machine. Perhaps that handshake got messed up the first time you plugged it in?

My phone was set to "trust" the Mac, and I still ran into this error with Xcode 6.1.1.
This worked for me:
Unfortunately this is too often the solution for many of your weird Xcode woes.

I recently ran into this issue with XCode 8 just after updating my device from iOS 9 to 10. The exact error I received was:Development cannot be enabled while your device is locked. Please unlock your device and reattach. I received this error even when my phone was unlocked, and after unplugging and re-plugging in the device.
Development cannot be enabled while your device is locked. Please unlock your device and reattach.
As is mentioned in several answers, the device is locked message is actually referring to the device not trusting the MacBook. In my case, I think my phone defaulted to not trusting my computer after updating to iOS 10. Here are the steps that worked for me to reset the settings (this is the same process that is mentioned in the Apple support page in tehprofessors' answer):
device is locked
Settings > General > Reset
Reset Location & Privacy
device locked
yep unfortunately only this worked for me on from Xcode 8 on iOS 10 :(

@BishalGhimire Yeah, it's definitely not ideal. I actually just had to do this reset again as XCode started giving me the
device is locked message again without any noticeable changes to any of my iPhone's settings or XCode's settings. Somewhere along the way my trust settings for my computer are being reset, but I'm not sure when and where.– Iron John Bonney

Hmm... this fixed the "Device Locked" error ... but has replaced it with a "Could not save the pairing record." error ...

From the Window Menu in top bar of Xcode, select Devices and Simulators.
(or Press SHIFT + COMMAND + 2)
Then select your device, right click and select Unpair.
Once you do this Trust or Don't trust will appear on your device.
Trust the device again and it will begin preparing it for Development.
Wait for Xcode to pair device for development and then you are good to go!
The problem usually is not waiting for xcode to prepare iPhone to debug :) this worked

I ran in to the same issue even though i selected "Trust this computer" option first time.
This worked for me
Abhi Beckert's answer above worked for me before, this worked for me now. I spend a ridiculously large amount of my time tap-dancing around Apple's inept developers.

For anyone who need a logical answer..
This worked. Make sure your device is UNLOCKED when you initially pair it. If not then follow these instructions to repair.

Rebooted my iPhone, and that fixed it for me.
I tried every answer on this page (7 at the time, though 2 are duplicates) and they were all unsuccessful for getting rid of this Xcode error for me.
This saved my day! Thank you!

Didn't helped for me. Only setting untrusted and trust again helped.

You don't need to reboot or restart every time..check my answer: stackoverflow.com/a/50023756/9623144

For those who has this issue in Xcode 9:
Simply restarting Xcode should solve the problem.
This is correct and especially true in the case of wifi debugging in Xcode 9.

A simple solution:
First, unplug your device.
Now, unlock your device and plug it in again. Be sure that the device is unlocked.
Now run the Xcode project by selecting the device as target.
The same for me. With addition that I was able to debug wireless.

When you plug in your iPhone, it will ask you to trust the computer.
If you already trust and unlocked but still said your device was locked (bug). Just unplug and plug again then it will work
This happens at times while using Xcode 9.
There are multiple solution to this as mentioned below :
Note : Make sure that your device is not locked when Xcode is trying to install app.
Solution 1 :
i. Disconnect device and connect again
Disconnect device
connect again
Solution 2 :
i. Restart you device
Restart you device
Solution 3 :
i. Disconnect device
Disconnect device
ii. Quit Xcode (Shortcut key : cmd + Q)
Quit Xcode
cmd + Q)
iii. Open your project
Open your project
iv. Clean project (Shortcut key : cmd + shift + K)
Clean project
cmd + shift + K
v. Now connect device
connect device
vi. Run your project
Run
For me Solution 3 worked perfectly
Solution #3 is what worked for me.

Recently I have met the Xcode shows "development cannot be enabled while your device is locked, Please unlock your device and reattach. (0xE80000E2).
If your iOS device is already unlocked and connected to mac and still get the error from Xcode 8.1 after upgrading to iOS 10.1.1, then the mac is not trusted by the device.
To fix it, first disconnect device to mac and then go to iOS settings app, and open general->reset->Reset Location & Privacy.
Then connect device to mac and when prompted, set select trust the mac.
Then wait the processing symbol files within your device and mac. After it finished, you can run the project to your device. It will be working.
Solution: Switch target device to some other (e.g. Generic iOS Device),
then unlock you physical device and switch back to it again.
This issue is not about "Trust" or not. It's a bug in Xcode.
Just follow these steps:
When Xcode is running and your device is connected:
1. Lock your device.
2. Unplug your device from Mac.
3. Unlock your device.
4. Plug your device back to Mac.
Still not working(

I follow the below steps its worked for me in iOS 10.
Lots of answers, but the one that worked for me (El Capitan, Xcode 8.2) was to close iTunes. If that has a connection to the IOS device then although Xcode can load the app components it will still fail to run it.
I found that by shutting down a Console and a running Simulator allowed XCode to see my iPhone again. I'd make sure other related programs aren't running if you don't need them.
This can also happen due to pending update on your device. This also means you need to update your phone, connect to the MacBook (trust it if needed). This how I found my problem and solution.
I had the same problem (update was waiting on device) but I didn't have time to update it. Asfand Shabbir's answer worked. (in case readers don't have time to update)

Generally just unplugging/replugging seems to work for me. But today it didn't and something else seems to have worked: I have enabled network debugging on the device in question and it almost looked like it remembered an old network "lock" setting, while not seeing that the device was actually connected via USB. After (temporarily) de-selecting "Connect via Network" and replugging, it got things working again.
sometimes your device stops trusting your PC for no reseaon. go to your settings then general > reset > reset location and privacy. and replug your device to your PC again and press "trust this device" prompt that shows up in your phone.
Another fix to this problem is to connect your iPhone with your Xcode open while your iPhone is in the homescreen, not in lockscreen or with an app opened.
All the previous solutions didn't work.
Finlay, changing the iPhone's cable solved the problem.
On your device (iPhone/iPad) goto: Settings -> Developer -> Clear Trusted Computers worked for me.
this is what I had to do as well to get the 'trust this computer?' prompt to appear when I connected to my computer

I had to re-add device to xcode.
In XCode open Devices and Simulators (CMD+Shift+2), in left list press + button and re-add the same device.
Check the "Low Power Mode" in disabled. In my case I just disable this check and the deploy works immediately,
One possibility worth checking, if none of these other solutions work, is that there is no space left on the device. Xcode will not give you a helpful "device full" error to tell you that your device has no storage space left, but it will also not be able to deploy an app build to a device whose storage is full. The only solution in that situation is to delete media or other apps/data to free up enough space.
Bizare, but I hope it helps someone.
I was connected to a VPN (Pro XPN) and that was causing the issue! Disconnected and it worked.
The fastest way for now i found is:
1) Go to Window -> devices (changed the hotkey in xcode to CMD+P for me)
2) Press unpair on the device. 
3) Press trust in iPhone.
4) Build again or Run without building (Ctrl+CMD+R)
