iOS 12.4 is missing in Xcode 11 GM - ios

I have installed Xcode 11 GM and can't find iOS 12.4.1 simulator anymore. iOS 12.4.1 was installed in Xcode 10.3, but it is not available in Xcode 11 for some reason (not only iOS 12.4 - other simulators are also missing). Moreover, I can't download it via "Add Additional Simulators..." - the latest one available is 12.2. Any ideas why so and how to fix? 🤔
Thanks!

iOS 12.4 simulator files can be found in the Xcode 10.3 app bundle. While you can't download it from within Xcode (at the moment), you can simply copy them to the folder where additional simulators are usually installed. Go to the following subfolder, it is located inside Xcode.app (10.3):
Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes
and copy the iOS.simruntime package to here:
/Library/Developer/CoreSimulator/Profiles/Runtimes
Rename iOS.simruntime to iOS 12.4.simruntime.
Restart Xcode 11.

The 12.4 simulator is now available (in Xcode 11.1 at least):

How to run Xcode 11.4 on macOS Mojave 10.14.6

Background on problem:
I have an iPhone 6s that has updated itself to iOS 13.4. Before the iOS update, I could code + run my app on the device from Xcode, great.
Now I can't run my app from Xcode on the device to test my code, as it says:
Xcode could not locate device support files
This iPhone 6s is running iOS 13.4 (17E255), which may not be supported by this version of Xcode. An updated version of Xcode may be found on the App Store or at developer.apple.com.
So I tried installing the latest Xcode (11.4) which now says I have to update my whole OS to Catalina.
I don't want to do this as my system is working fine and I have heard bad things about that release.
Question:
Is there a way I can get Xcode building to my iPhone without updating my whole OS and potentially screwing up my whole machine?
You cannot run Xcode 11.4 on Mojave but you can add support for iOS 13.4
Download the 13.4 image from this repo
Quit Xcode
Unzip the archive and move the folder into /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Launch Xcode
Consider that this way adds only the support for iOS 13.4, nothing else.
Update: This does not work with iOS 14 because iOS 14 requires Xcode 12.
Here's an alternative solution that doesn't require downloading files from an untrusted source:
Install the latest release of Xcode that runs on Mojave (currently Xcode 11.3.1). It can be downloaded from Apple's developer pages.
From the same page, download a release of Xcode that supports iOS 13.4 (for example Xcode 11.4.1). Unzip it, rename it to "Xcode-11.4.1.app" and move it to the Applications folder, but don't run it.
Add a symbolic link for iOS 13.4 from the DeviceSupport folder in Xcode 11.4.1 to Xcode 11.3.1, as described in Peter Steinberger's Gist.
If you use the versions used in this answer, the command to add the symbolic link would be
sudo ln -s /Applications/Xcode-11.4.1.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/13.4 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
You can run Xcode 11.4 - 11.7 on your Mac which is running 10.14.
Download Xcode 11.4 ~ 11.7 from https://developer.apple.com/download/
Extract the .xip file, and you will get Xcode.app
Modify LSMinimumSystemVersion in Xcode.app/Contents/Info.plist from 10.15.x to 10.14
Now you can use Xcode 11.4 ~ 11.7 without upgrading to Catalina.
However, this trick doesn't work for Xcode 12, which requires some frameworks that do not exists in macOS Mojave.
My Apple TV 4K was running tvOS 13.3 and I upgraded to 13.4 which required that I use this technique to keep working with Xcode 11.3.1.
What is odd is that in the DeviceSupport folder, Xcode 11.3.1 only ships with tvOS up to 13.2. So how did it ever work with a hardware device running 13.3? I guess 13.2 and 13.3 are close enough that 13.2 still works.
13.4 does not work out of the box, so I copied both 13.3 and 13.4 from the Xcode 11.4.1 app into my 11.3.1 app. All is well again.
You can run Xcode 11.4 - 11.7 on your Mac which is running 10.14.
Download Xcode 11.4 ~ 11.7 from https://developer.apple.com/download/
Extract the .xip file, and you will get Xcode.app
Modify LSMinimumSystemVersion in Xcode.app/Contents/Info.plist from 10.15.x to 10.14.6
Now you can use Xcode 11.4 ~ 11.7 without upgrading to Catalina.
However, this trick doesn't work for Xcode 12.
I tried this trick on my mac mojave 10.4.6

Xcode 11.3 cannot set target for iOS 13.3, i.e. the option doesn't exist

I upgraded to Xcode 11.3 and Catalina 10.15.2 recently. The release note stated
Xcode 11.3 includes SDKs for iOS 13.3
However, the iOS 13.3 deployment target, as well as the simulator, doesn't exist.
Edit:
The iOS 13.3 deployment target doesn't exist.
Is it a bug? Or a problem of my installation? Is there a workaround?
Edit: A Link to the apple developer forum Xcode 11.3: can't select deployment target 13.3 https://forums.developer.apple.com/thread/126948
Additional screenshot:
I think you're right (even though I didn't believe it at first). When you look inside Xcode, the only SDK is iOS 13.2.
They didn't include the iOS 13.3 SDK even though the release notes claim that they did.
If you are on Catalina download Xcode Beta11.4, it supports 13.3.1
If you are on Mojave you will not be able to install Xcode Beta11.4 but there's still a way.
You can extract the DeviceSupport + SDK files from Beta11.4 copy them in Xcode 11.3
Do not forget the SDK files, without it it didn't work for me.

No Xcode support for iOS 12.3

My phone has updated to iOS 12.3 beta, the latest Xcode 10.2 beta only supports up to iOS 12.2.
Is there a beta version of xcode anywhere that is compatible with iOS 12.3?
I guess the options are to wait for apple to release a new version of xcode or to roll back. unless anyone knows otherwise?
I find a solution to fix this problem.
You should make a folder named 12.3 (... what is written in your error message) in Program/Xcode-beta/Contents/Developer/Platforms/iPhoneOS.platforms/DeviceSupport/ and copy the files from 12.2 in there.
Now you can run your apps on iPhones with iOS 12.3.
Any update on The IOS 12.3 Beta Developer Disk Image?
The official Debugging File for iOS 12.3 is not available.
You can try the following method to let Xcode support debugging iOS 12.3 devices.
1. Go to the folder /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
2. Create a folder named "12.3".
3. Copy the "12.2" file to the "12.3" folder.
How I fixed a similar issue with iOS 12.4
Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport and create folder called 12.4 (16G77) and copy the files from one of the previous folders f.e 12.3
Go to Xcode and click on the "Set active scheme menu" and click on Download Simulators at the bottom:
Xcode will automatically start updating and re-creating the supporting files for 12.4:
Hope this will help someone.
Actually, Xcode 10.2.1 could debug with real devices running iOS 12.3
Try it by yourself.
worked for me:
1. cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
2. cp 12.0 12.2
3. cp 12.0 12.3
4. downloaded Apple configurator and identified the connected devices
5. in xCode targeted the connected device
6. build worked
How I fixed similar issue with iOS 12.5.3 (XCode 10.1)
I opened Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport in Finder, created folder called 12.5.3 (16H41) and copied the files from folder 12.4 (16G77).

iOS 12 not supported by Xcode 9.4 : Could not locate device support files

This iPhone 8 (Model A1863, A1905, A1906, A1907) is running iOS 12.0 (16A5308e), which may not be supported by this version of Xcode. (Version 9.4.1 (9F2000))
can anyone help with iOS 12.x device support files from Xcode 10 beta?
iOS 12 is only supported by the beta of Xcode 10 or higher.
If you want to use your iPhone 8 with this iOS version (NOT RECOMMENDED) with your Xcode 9.4 you can try to download the last beta of Xcode 10 and after connecting the iPhone to the mac go to this folder:
/Applications/Xcode10.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
You can see the iOS version folder of the iPhone, copy and past it to the same location in your Xcode 9.4 folder.
After this you should be able to deploy to your iPhone 8.
As answered by #Kerberos you can copy the iOS 12 device support files to:
/Applications/Xcode10.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
👉 https://github.com/Yatko/iOS-device-support-files
The link provided by Yatko is not supporting the newest iOS 12 versions (public release).
This repository has more iOS versions to offer: https://github.com/iGhibli/iOS-DeviceSupport
Copy the files to the same path as described by Kerberos.
Another convenient way to achieve this without downloading Xcode 10.
https://github.com/sauravexodus/xcode-9-ios-12-support
Note: If you have multiple Xcode versions then be careful with the path written in install.sh file.
Just download latest OS SDK (iOS 12.2) and paste it on respective location.
Downloadable URL:
13.2
13.1
13.0
12.4
12.3
12.2 (16E226)

10.0 (14A5339a)
Follow below step.
1) Unzipped downloaded file
2) Right click on Xcode and click on Show Package Content
3) Then paste your file on path
Contents -> Developer -> Platforms -> iPhoneOS.platforms -> DeviceSupport
4) Restart Xcode
Is it very convenient, saving the trouble of updating Xcode. what? You can't find a new Device Support file! Ok, you can copy it out from your friend's latest Xcode, or download from here
Update:
The added iOS Disk image for iOS 13.0, 12.3 and iOS 12.4

Xcode not supported for iOS 11.3 by Xcode 9.2 needed 9.3

Apparently, with the latest IOS update, my version of Xcode could not build due to the following error.
Could not locate device support files. This iPhone 7 Plus (Model 1661, 1784, 1785, 1786) is running iOS 11.3 (15E216), which may not be supported by this version of Xcode.
Tried to install Xcode 9.3 via this link https://developer.apple.com/download/more/. But as it turns out, my Mac OS version sees the update as an incompatible version. Running on Sierra 10.12.6
Another option is to download the 11.3 device support at:
iOS 11.3 (15E217)
And don't forget to remove "(15E217)" from folder name, so it became "11.3". Restart Xcode afterwards.
Where to paste it according to comment of EdwardM
For those that don't know where to paste the contents of the zipped file. Find your Applications icon in the dock, right-click, "Open Applications". The folder will open in Finder. Right-click Xcode > Show Package Contents. Then go to Developer > Platforms > iPhoneOS.platform > DeviceSupport
I have the same problem, OS Sierra trying to run iPhone SE with 10.3 using Xcode 9.2 and I don't have the resources to update to High Sierra and Xcode 9.3.
Solution:
Find your friends who have Xcode 9.3
Ask them to right click on Xcode, Show Package Contents then navigate to Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/11.3 (15E217)
Copy the 11.3 (15E217) folder to your old Xcode (9.2) with the same file hierarchy
Now you have Xcode 9.2 with iOS 11.3.
I just give you a device support file for iOS 11.4 (15F79).
which just on XCode version 9.4 (9F1027a)
Updated on 5 Oct 2018:
Xcode 10.0 (10A255) - iOS 12.0 (16A366) [Updated 21 Sep: #Nik
Burns confirmed that works]
Xcode 10.1 beta 2 (10O35n) - iOS 12.1 (16B5068g) [Please give me feedback if that works]
I have macOS 10.12.6
You can download Xcode 9.3 from https://developer.apple.com/download/
and extract the "11.3 (15E217)" folder from it
The fix really works.
please add both of "11.3 (15E216)" and "11.3 (15E217)"
keep all of them inside /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform
I recently stumbled upon the same problem, where I basically updated my iPhone X to the newest OS version, and (for reasons I will not go into) had to run the app on Xcode 9.2.
This thread was helpful, but there's one small caveat that even though I downloaded the newest support files from the provided Github project, and put them in the appropriate folder, I was still getting this error:
Say for example you’ve downloaded 11.4 (15F79) but after restarting and running again you get an error mentioning something like 11.4.1 (15G77).
The solution, as I wrote here, was to just rename the folder (so, rename 11.4 (15F79) to 11.4.1 (15G77)), restart Xcode and voila, it works!
Hope this helps someone 👍
I have macOS 10.13.4
I downloaded Xcode 9.3
Here you have the "11.3 (15E217)" it's work fine.
Quicker/Smaller Fix
This is probably due to outdated Xcode, if you don't want a big Xcode update due to limited storage/time then you can manually download the required support files instead of the whole update.
Download the files (depend on iOS veersion) from here
And then paste the downloaded files in below directory /Applications/Xcode/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
