I updated to iOS 13 on my iPhone X and have Xcode 10.3 and am unable to run my project ton my phone. It gives me a notice of:
Could not locate device support files
and gives me this error:
This iPhone X is running iOS 13.0 (17A577), which may not be supported by this version of Xcode
I've looked everywhere, but since this release is new, how can I fix this?
Your version of Xcode does not have the supporting files for running iOS 13.
The easiest way to do that is to have Xcode 11 installed on your mac (or on someone else's mac) in addition to Xcode 10.3 (it's better to rename one of them)
Go to Applications folder, right click on Xcode 11 icon → Show Package Contents, navigate to folder Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
And copy the folder 13.0
Go back to Applications, right click on Xcode 10.3 icon → Show Package Contents, navigate to folder Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Now, paste that folder.
Quit Xcode and run again.
Happy Coding 👨💻
You should upgrade your Xcode to the latest 11.0 in App Store, which contain support for iOS 13.
I downloaded the Developer disk image for iOS 13.0 from here and added support file in Xcode Version 10.3 (10G8).
https://github.com/iGhibli/iOS-DeviceSupport/blob/master/DeviceSupport/13.0.zip
All other devices support list.
https://github.com/iGhibli/iOS-DeviceSupport/tree/master/DeviceSupport
Follow These steps.
Unzip downloaded file. Right click on Xcode and click on Show Package Content. Then paste your file on path.
Applications -> Xcode.app -> Contents -> Developer -> Platforms -> iPhoneOS.platforms -> DeviceSupport Then at last restart your Xcode.
It works for me.
I have this error for the new iPhone X:
Could not locate device support files.
This iPhone X (Model A1865, A1901, A1902, A1903) is running iOS 11.1 (15B93), which may not be supported by this version of Xcode.
I'm running the latest version of Xcode (Beta 9.2 9C32c) which doesn't support the iPhone X (iOS 11.1). The problem is it's a brand new iPhone, and there are no older Configuration Files to do the switch talked in most of the solved posts.
Are there any other solution to this issue since downloading the latest version of Xcode is already what I'm running, and finding the Configuration Files to do the switch seems unlikely right now? Does anyone have those Configuration Files or know how to edit them to trick Xcode?
Answer: Xcode: Could not locate device support files
Well, I found non of the answers logged out here aren't complete and sustainable. So here we go.
Most importantly don't waste your time and internet bandwidth downloading Xcode just to resolve this issue which you can do within few MBs and little bit of OS know-how!!!
Step 1:
Following GitHub Repository seems to be up to date with all the required Support Files which are helpful to resolve. And it seems like this repository gets updated quicker as possible. Check out it for yourself and you are halfway done.
https://github.com/filsv/iPhoneOSDeviceSupport
Step 2:
Select and download the Support files which are missing for your Xcode, which you can get the clue out of the above alert message. In my case I was informed to download 11.4 (15FCA...something). So I went and downloaded the latest iOS Support files:
Which were under the path of iPhoneOSDeviceSupport/11.4 (15F5061c)/
DeveloperDiskImage.dmg
DeveloperDiskImage.dmg.signature
Step 3:
And then place them inside the DeviceSupport folder which is in a related path to your Xcode installation. In my case, I've installed Xcode 9.2 so my path to DeviceSupport looks like as follows:
/Applications/Xcode-9.2.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Step 4
Place the two files you downloaded in a folder named 11.4 (15F5061c).
Clue: In your case make sure to name it after the specific iOS version you downloaded the files.
Step 5:
Quit Xcode app if you had been already using it previously. Re-open it and try to run your app on your iPhone (or in iDevice of your previous attempt). Xcode will first warn you saying something like following:
Preparing debugger support for Randika's iPhone 6s
Soon after it's completed (probably after several attempts that you may have to try reconnecting your iPhone to Xcode), you would be able to successfully run your app on your preferred device.
How could you find this path?
Go to your Applications folder, locate Xcode-x.x.app file, right click on the Xcode app and select "Show package contents" as follows:
And then navigate to the DeviceSupport folder within the Finder App as follows:
Hope this would be helpful to any of you!
Cheers!
I had the same issue with my iPhone 8, Xcode Beta 9.2 did not support my version of iOS 11.1.
However Xcode 9.1 does support my version of iOS 11.1
This error can be fixed with 2 ways.
1.You need to keep updated with latest Xcode versions.
2.You can fix it without updating to latest Xcode, in this you just need to update device support file,
To update device support file just follow the steps,
You can find the Device support file and update it with the below path details,
Path-
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
You can download device support file from this links

How to add a file in xCode
Open Finder
Open the application folder
Find the Xcode app inside
Click on Xcode, right click -> show package contents
Find the supported real machine test files in the following directory hierarchy:
Contents -> Developer -> Platforms -> iPhoneOS.platform -> DeviceSupport(/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport)
The above directory is the real version of iOS that Xcode supports real machine debugging, as shown below:
Then copy the latest DeviceSupport file to this directory through other channels and restart XCode to debug with the latest iOS device.
I'm uncomfortable downloading shards from 3rd parties; also, it sounds like the iOS 13.2 support file linked above is based on a beta, which now crashes.
I would recommend downloading Xcode directly from Apple, and install the new version side-by-side with the version of Xcode which you need to use (if you're pinned by a Swift binary framework, for example).
rename your current Xcode application bundle (Xcode --> Xcode_11)
download latest Xcode from AppStore (Xcode 11.2)
launch new Xcode, installing Command Line Tools, then exit
launch your older Xcode (Xcode_11), and build and run on device
In my case, device support files were already present but I was still facing the issue. The reason was that folder present at this path
/Applications/Xcode-9.2.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
was having name 12.1 (16B91) but the xcode was giving error for 12.1 (16C101) so renaming the folder to 12.1 (16C101) did the trick
I was able to run it, by first using BuddyBuild.com to send me a tester app through email, that I downloaded successfully. After that, I was able to build the app.
Open Xcode show package content
go to /Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport and drop the 13.0 folder into this folder and restart the Xcode.
Download the file here:
https://bitbucket.org/bneves/ios13_devicesupport_xcode_10.3/
Now I have an app based on Xcode 7.3.1 which runs fine. But one problem happened when I want to install the app to an iOS 10 device. It is said "Could not find Developer Disk Image". So I find a solution which is this: https://danielemargutti.com/solve-xcodes-could-not-find-developer-disk-image-error-how-to-run-projects-in-ios-10-device-using-xcode-7/
However, there is no 10.0 folder in the "/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport". So I found an easy way (looks like) to install both version of 7.3.1 and 8 which is this: https://www.quora.com/What-is-the-best-advice-to-install-Xcode-8-beta-alongside-Xcode-Version-7-3-1
The question is how can I only download the 10.0 folder rather than install Xcode 8 and make a link or copy/paste into Xcode 7.3.1? Thanks in advance of any other solutions.
I have that uploaded on Dropbox

NOTE: Swift 2.3 support is not available from Xcode 8.3 + versions
Go to your Applications -> Xcode 7.x version.
Right Click it and click on Show Package Contents and navigate to the path below :-
/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
And paste the unzipped folder (iOS 10.0) at the path mentioned above. It will look like this.
In the Device Support Folder for Xcode 7.3.1 version you currently will be having folders upto 9.3 only. Simply paste this iOS 10 folder there.
Finally, Quit and Restart your Xcode and plug in your iOS 10 Device.
Open Finder and from its Top menu click on "Go" and then click on "Go to Folder..."
You'll see one prompt and there paste this below line there,
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
You'll be redirected to "DeviceSupport" folder.
Now, Download folder from below link and unzipped it
https://drive.google.com/file/d/0B_9nnatiB3jRaElIeDQzWXNzeEU/view?usp=sharing
Copy and Paste that folder in "DeviceSupport" folder.
Restart XCode and enjoy :)
You can download iOS 11 official developer disk image from here
Unzip & Paste it in
Applications > Right Click on Xcode > Show Package Contents and follow the below directories and restart your XCode.

After updating my iPad to iOS 9 public beta, I am getting an error while trying the run the app in my iPad. When I select the iPad as destination, it says "iPad (Unavailable) or Could not find developer disk image. How can I fix this? Any solution?
If you are using the Xcode 7 GM build version 7A218, the chances are that you accidentally downloaded iOS 9.1 (13B5110e) as opposed to the iOS 9 GM build (13A340). I did the same thing don't worry. They are too close to each other on the downloads page :0
You can check which version you have on your device by simply going to your device Settings > General > About > Version
All you have to do is download the correct iOS 9 GM build and go to iTunes. Click on your device. In the summary tab, OPTION + Right Click "Check for Update" and restore your device by navigating to the iOS 9 GM build finder location. Note by selecting "Check for Update" you will not lose any settings or data on your device. In other words, it is not a restore
However, if you are using Xcode 7.1 build version (7B60) iOS 9.1 is supported
I had the same problem and all I had to do was to update my XCode to 7.1. After that it worked. Your Xcode has to be updated to the latest version.
This is also encountered when trying to use Xcode 6.4 against an iOS 9.0.x device. Here's how you can workaround it and get Xcode 6.4 to recognize your iOS 9.0.x devices:
Download Xcode 7.0.1:
http://developer.apple.com/devcenter/download.action?path=/Developer_Tools/Xcode_7.0.1/Xcode_7.0.1.dmg
Open Xcode_7.0.1.dmg and drag the Xcode.app to your desktop
Right-click, Show package contents, navigate into /Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Copy the "9.0 (13A340)" directory to the existing DeviceSupport directory for your Xcode 6.4 install. For example: ~/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Restart Xcode 6.4 (if it was running), and your device running iOS 9.0.x should now show as a recognized device.
I solve this problem by just simple xcode restart.
Update Xcode. If it not help:
go to
/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
If you don't find there your device iOS version, you could try to copy last one and rename it to which one do you need, restart XCode and try to compile, it works for me.
Apple just released the new Xcode 7.1 which support iOS 9.1. Update Your Xcode and everything will be fine.
I have experienced same issue
Could not find Developer Disk Image
1) My Xcode version was 7.0.1 and i updated my iPhone to version 9.2, then upon using Xcode my iPhone was shown in section of unavailable device. Just like in image below:
2) But then i somehow managed to select my iPhone by clicking at
Product -> Destination -> Unavailable Device
3) But that doesn't solved my problem and started showing
Could not find Developer Disk Image
Solution) Then finally i downloaded latest version of Xcode version 9.2 from https://developer.apple.com/downloads/ and everything worked fine for me.
For me the problem was that I just needed to open my phone and click "Trust Computer"
I had XCode 7.0.1 installed + iOS 9.1 (13B143).
XCode had shown me "unsupported device" / "could not find developer disk image" in Devices windows until i updated my XCode to version 7.1. Everything works well now.
I had already update to newest version Xcode (7.0.1) but still can't build on iPod touch 5 in iOS 9.1(13B143).After copy 9.1 (13B137) folder from my colleague to DeviceSupport folder in Xcode, it works! Not sure it would create some side effects.
When attempting to run a build on a connected iOS device in Xcode I get the error:
Could not find Developer Disk Image
I saw that there was a public beta for Xcode, so I installed it.
One of the new features is that you don't need to have a Developer Program Account Dingus to upload your app directly to your iPhone.
However, on my iPhone 4s, I also did a public beta update to iOS 8.4, problem being, that there's no Developer Disk Image available for it.
Where do I to find it or how can it be fixed?
For people who would have similar problems in the future, beware that this problem is fundamentally rooted in the mismatch of your iOS version and Xcode version.
Check the compatibility of iOS and Xcode.
I personally downloaded Xcode 6.4 beta and 7.0 beta and I was very happy to find the solution by searching "8.4" inside the application folder of the 6.4 beta. By doing this, I found the folder 8.4 (12H4125a) containing the iOS 8.4 image and I copied this folder to the same path of the 7.0 beta. The path is the following:
/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
When you will reopen Xcode 7 and choose your device, there will be an error message; just click on fix issue and that should do it!
This error occurs when the version of Xcode predates that of the device.
For example, attempting to run a build on a device running iOS 9.3 in Xcode 7.2 results in this error; Could not find Developer Disk Image.
Why an error message that actually describes what the hell is going on can't be provided is beyond me (Apple, I'm looking at you 👀).
Update to the latest version of Xcode through the App Store or via direct download to guarantee interoperability with connected iOS hardware.
I am facing the same issue on Xcode 7.3 or Older version of your Xcode and my device version is iOS 10 or newer version of your OS.
This error is shown when your Xcode is old and the related device you are using is updated to latest version.
We can solve this issue by following the below steps:
Method 1:-
Right click on Xcode 7.3 or version of your Xcode, now select "Show Package Contents", "Contents", "Developer",
"Platforms","iPhoneOS.Platform", "Device Support".
Now check there is latest version of developer disk image(folder) like 12.1 or newest version(folder) in your case. Copy the latest
version and Paste in the same Folder Device Support.
In my case I have 12.1 is the latest folder. Now it will generate the copy of that version like 12.1 copy or newest version(folder)copy
in your case.
Now Change the name of copy folder to your latest version of iPhone like. In mine case, I have 12.1(Folder)copy and rename it into 12.4. As you can see in the above screenshot. You can change it according to your latest version of phone. I need it for 12.4 so i just rename the folder to 12.4.
Now your Xcode has a new developer disk image. Close the finder now,
and quit your Xcode. Open your Xcode and the error will be gone. Now
you can connect your latest device to old Xcode versions.
**OR**
Method 2:-
First of all, download the latest Xcode Version. No Need to install the latest Xcode.
We can solve this issue by following the below steps:
Right click on Xcode 8 or Newer version of your Xcode, select "Show Package Contents", "Contents", "Developer",
"Platforms", "iPhoneOS.Platform", "Device Support"
Copy the 10.0 folder (or above for later version).
Back in Finder select Applications again
Right click on Xcode 7.3 or version of your Xcode, now select "Show Package Contents", "Contents", "Developer", "Platforms",
"iPhoneOS.Platform", "Device Support"
Paste the 10.0 folder (or above for later version).
Now your Xcode has a new developer disk image. Close the finder now, and quit your Xcode. Open your Xcode and the error will be gone. Now you can connect your latest device to old Xcode versions.
OR
If you can't download the latest Xcode, you can get the latest
Developer Disk Image for your Xcode from this link:-
https://github.com/Yatko/iOS-device-support-files
Thanks to Yatko. So that people can download the latest DMGs.
If you're using old Xcode and want to run onto devices with new version of iOS, then do this trick. This basically make a symbolic link from iOS Device Support in new Xcode to old Xcode
https://gist.github.com/steipete/d9b44d8e9f341e81414e86d7ff8fb62d
For Xcode 9.0 beta and iOS 11.0 beta (name your Xcode9.app for Xcode 9 beta and Xcode.app for Xcode 8)
sudo ln -s "/Applications/Xcode9.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/11.0\ \(15A5278f\)" "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport"
My problem was with Xcode 7 and Xcode 6.4 beta and iOS 8.4 - device not compatible.
In case of the same problem for better understanding how to fix, do next:
Go to /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Go to
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
Copy folder iOS 8.4 in another folder
Restart Xcode
If you have iOS 9.1 on your phone, just download Xcode 7.1 beta instead of using GM.
See Apple's response: Could not find developer disk image for iOS 9.1
I got the same error message (Couldn't find developer disk image) after I updated my devices to iOS 9.2, but forgot to update to Xcode 7.2.
So in my case, the fix was easy: just update to Xcode 7.2 via Mac App Store.
This message appears when your version of Xcode is too old for the device's version of iOS. Upgrade Xcode to the latest.
If the App Store doesn't offer an update for Xcode, upgrade to the latest Mac OS. In the past, Apple has been rather aggressive about dropping support for past versions of Mac OS X in the latest Xcode.
EDIT: yes, this error started popping up all over again. :) Xcode 7.3.1, which is the latest one that's available for MacOS 10.11 (El Capitan), doesn't support iOS 10. You need MacOS Sierra (and possibly a new Mac).
I just got this, and I'm on Xcode 7.2.1... It appeared when I downloaded iOS 9.3. Check your Project -> Base SDK and if it isn't the same or ahead of your device version, then that's the issue. I didn't see anything in the "Updates" section, but when I searched "Xcode" in the App Store it had an update for 7.3.
Upgrading to iOS 9.3 and Xcode 7.3 requires Mac OS X v10.11 (El Capitan) for Xcode to run, and that's why auto update isn't upgrading Xcode versions.
This problem is a mismatch of your iOS version and Xcode version.
Example:
You have an iPhone with iOS 9.3 GM and your Xcode version is 7.2.1. This leads to the issue that you have to update your Xcode to 7.3 which includes SDKs and related stuff for iOS 9.3.
There actually is a way to deploy to a device running a newer iOS that the particular version of Xcode might not actually support. What you need to do is copy over the folder that contains the Developer Disk Image from the newer version of Xcode.
For example, you can deploy to a device running iOS 9.3 using Xcode 7.2.1 (which only supports up to iOS 9.2) using this method. Go to the Xcode 7.3 install and navigate to:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
From here, copy over the folder that contains the version you are trying to run on the older version of Xcode (for this example, it's 9.3 with the build number in parenthesis). Copy this folder over to the other install of Xcode, and now you should be able to deploy to a device running that particular version of iOS.
This will fail, however, if you're utilizing API calls that were specifically added to the newer version of the SDK. In that case, you will be forced to update Xcode.
I have experienced the same issue:
Could not find Developer Disk Image
My Xcode version was 7.0.1, and I updated my iPhone's version to 9.2, and upon using Xcode I ran into this problem.
The solution is pretty simple: Just download the latest version of Xcode 7.2 which was released on 8 Dec, 2015 and install it. Everything works fine for you as it was before.
Note: The actual problem is your Xcode version is not compatible/outdated with the version on your device.
This error is shown when your Xcode installation is too old and the related device you are using is updated to latest version.
There are multiple ways to solve this issues.
1. Update your Xcode installation.
This is by far the simplest method. Just update your Xcode installation to the latest stable version and things would start working again.
Note: Please update your OS as well if Xcode doesn't support your current OS. Which brings us to...
2. Manually copying Device Disk Image. No update needed.
This is the clever way around. You don't have to update your Xcode installation or your OS for this.
First open the XCode.dmg and select Show Package Contents.
Phase 1: Getting the downloaded Xcode ready.
Steps:
Download the latest Xcode.dmg from Developer portal.
Select the downloaded Xcode.dmg and right click on it.
In the options, select Open With → DiskImageMounter.
Now in Finder, open the Xcode disk.
In the disk, right click on Xcode.
Select Show Package Contents.
Now, a new finder window opens. Follow the instructions below to copy the disk image.
Phase 2: Copying the Developer Disk Image.
Steps:
In the new finder, go to Contents.
Inside Contents, Go to Developer.
Inside Developer, go to Platform.
Now select the desired platform. For our purpose, we are going to update iOS disk image only.
Inside Platform, go to Device Support.
Inside Device Support, you'll find a lot of disk images. This includes the latest device disk images as well.
Copy all the folders inside Device Support. Select all and then copy.
Note: For step 6, You can copy the disk image you want to copy as well, i.e. copy the latest only. It's the last folder in the hierarchy here.
This ends the Phase 2, Copying the disk image. Now in the next phase, we will update the developer disk image of our Xcode installed on our device.
Phase 3: Upadting the Xcode's developer disk image.
Now, close all the finder windows for faster operation and less confusion.
We are now going to update our Xcode's disk image for iOS Platform.
Steps:
Close the Xcode application if it is open.
Open a new finder window.
Select the primary partition if you have multiple partitions.
Go to Applications.
Find XCode and right click on it.
Select Show Package Contents.
Finder window updates or opens a new window with Contents as the main directory.
Select Contents.
Inside Contents, select Developer.
Now, select Platforms.
Now, select iPhoneOS.platform.
Inside iPhoneOS.platform, go to Device Support.
Inside Device Support, select all the files and Move to Trash.
Note: SKIP step 12 if you copied only the latest disk image i.e. the last folder in the hierarchy.
Now, Paste the developer disk image we copied from Phase 2 here.
Final Step, right click and Paste here.
If everything worked properly, your Xcode has new developer disk image. Close the finder now, and open Xcode. The error should be gone by now.
Reminder: Don't forget to unmount the Xcode now from finder as well.
It works, in my case for Xcode from 7.3 TO 7.1. Copy directory 9.2, for iOS device OS 9.2.1.
As others suggested, this issue is caused by an incompatible iOS version (which is higher than the maximum version that Xcode supports). Normally it can be addressed by updating Xcode, but sometimes you may be restricted to do so, hence here's another workaround.
Head to developer.apple.com/downloads (or google similar stuff if this link dies) to grab the newest Xcode dmg image manually, and then mount it. If you're doing this already, the new Xcode is not likely working for you, but you can cp /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/NEW_IOS_VERSION /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/ to copy the image you want into the old Xcode you've installed.
Of course it's not guaranteed to work for future versions, but it's definitely worth trying. For me, my iOS version is 9.3.1 (13E238), but I copied 9.3 (13E230), and it works just fine.
This happens when your Xcode version doesn't have a necessary component to build the application to your target OS. You should update your Xcode.
If you are building a new application for a beta OS version that no stable Xcode version is able to build, you should download the newest Xcode beta version.
I also had this problem. I was using Xcode 7.3 for my iOS 10 beta iPhone, so I went to install Xcode 8-beta, and I did the following step to continue using the stable version of Xcode with new build tool:
Just like #onmyway133 answer, but more user-friendly is after finish installing the Xcode 8-beta version, go to Xcode 7.3 preferences (Cmd + ,), go to the tab locations, change the Command Line Tools to Xcode 8 in the dropdown list.
I successfully built to both iOS simulator 9.3 and my device iOS 10 beta using Xcode 7.3.
This problem is fundamentally rooted in the mismatch of your iOS version and Xcode version.
Check the compatibility of iOS and Xcode.
Go To Application folder (In finder) -> right click on Xcode -> click on show package contents -> Double click contents folder -> Double click developers folder -> Double click platforms folder -> Double click iPhoneOS.platform folder -> Double click device support folder -> then add latest developer disk image.
Or
Download Latest version of Xcode.
For iOS 10 beta 7, add the following link on the command line:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/10.0\ \(14A5339a\) /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
I have also faced this issue, and I'm on Xcode 7.2.
It appeared when I downloaded iOS 9.3.
Check your Project -> Base SDK and if it isn't the same or ahead of your device version, then that's the issue.
I didn't see anything in the "Updates" section, but when I searched "Xcode" in the App Store it had an update for 7.3. Upgrading to iOS 9.3 and Xcode 7.3 requires Mac OS X v10.11 (El Capitan) for Xcode to run, and that's why auto update isn't upgrading Xcode versions.
Just my two cents for iOS 10 (under NDA, but for people that can use it legally...)
Copying full folder (as other people said) works
Symbolic link seems not.
This was tested using Xcode 7.3 (std from Store) AND iPhone 6Plus with 10.0 (14A5261v).
by the way it DOES work even in Xcode Version 8.3.1 (8E1000a) adding an image for iOS 11 beta. I added 11.0 (15A5278f) inside
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
and works with my iPhone 7plus with new iOS 11 beta.
