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
回答1:
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.
回答5:
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 👍
