I recently upgraded iOS in my iPhone device to 12.2, and this does not appear to be compatible with Xcode 10.1. Should I update Xcode to 10.2 ?

In my Mac with High Sierra, when I click "Update" for Xcode, 10.2 is not available.

I have found this link: https://support.apple.com/en-us/HT209606

With this comment: "Xcode 10.2 Released March 25, 2019 Kernel Available for: macOS High Sierra 10.13.6 or later"

How can I install Xcode 10.2 with High Sierra in order to test iOS 12.2 ?

Note: Upgrading to Mojave is NOT an option in my old Mac.

Download xcode 10.2 from below link https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_10.2/Xcode_10.2.xip

Edit: Minimum System Version* to 10.13.6 in Info.plist at below paths

  1. Xcode.app/Contents/Info.plist
  2. Xcode.app/Contents/Developer/Applications/Simulator.app/Contents/Info.plist

Replace: Xcode.app/Contents/Developer/usr/bin/xcodebuild from Xcode 10


you can install disk image of 12.2 in your existing xcode to run on 12.2 devices Download disk image from here https://github.com/xushuduo/Xcode-iOS-Developer-Disk-Image/releases/download/12.2/12.2.16E5191d.zip

And paste at Path: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

Note: Restart the Xcode

You don't need to run Xcode 10.2 for iOS 12.2 support. You just need access to the appropriate folder in DeviceSupport.

A possible solution is

  • Download Xcode 10.2 from a direkt link (not from App Store).
  • Rename it for example to Xcode102.
  • Put it into /Applications. It's possible to have multiple Xcode versions in the same directory.
  • Create a symbolic link in Terminal.app to have access to the 12.2 device support folder in Xcode 10.2

    ln -s /Applications/Xcode102.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/12.2\ \(16E226\) /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

You can move Xcode 10.2 to somewhere else but then you have to adjust the path.

Now Xcode 10.1 supports devices running iOS 12.2

Yes it's possible. Follow these steps:

  1. Download Xcode 10.2 via this link (you need to be signed in with your Apple Id): https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_10.2/Xcode_10.2.xip and install it
  2. Edit Xcode.app/Contents/Info.plist and change the Minimum System Version to 10.13.6
  3. Do the same for Xcode.app/Contents/Developer/Applications/Simulator.app/Contents/Info.plist (might require a restart of Xcode and/or Mac OS to make it open the simulator on run)
  4. Replace Xcode.app/Contents/Developer/usr/bin/xcodebuild with one from 10.1

None of the above helped for me.

I was able to install Mojave using this link here: http://dosdude1.com/mojave/ This patch worked beautifully and without a hitch

Proof: here's Mojave running on my (unsupported) 2011 Mac-mini

Based on responses and comments below, the following was the solution for my issue and THIS WORKED:

  1. Download Xcode 10.2 from a direct link (not from App Store). (Estimated Size: ~6Gb)
  2. From the downloaded version just copy/paste the DeviceSupport/12.2 directory into "Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport"
  3. You can discard the downloaded version now (we just need the small 12.2 directory!)
