I updated my Mac Mini to Mojave also updated to Xcode 10, I've Xcode server configured in my Xcode 9.4.1 it was running even having some issues like couldn't able to install IPA directly into the device. Today I updated my Xcode and tried to update the Xcode server, it is throwing an error while starting Apache. Here is the screen shot.
I had the same problem with a new macOS 10.14 installation.
Any chance you have the latest version of macOS Server (5.7.1) installed too? Apparently the Xcode Server initialization process assumes that if you have macOS Server installed, then it can find a bundled version of Apache.
Since Apple gutted macOS Server recently, that assumption no longer holds, and the helper tools crash during initialization (check for xcsreciperunner crash logs).
I was finally able to turn on Xcode Server only after deleting the macOS Server app. Hope this helps.
I have been working on a project using Xcode recently, and I looked up instructions on a website, but the code was only for Xcode 7.1, and I only have Xcode 8! I followed the steps instructed on the website but there were way too many errors! Is there a way to downgrade Xcode without using the apple website or deleted the current Xcode I have now?
You can download both Xcode 8 and Xcode 7 into your computer. But you can't downgrade it.

I am trying to use the Xamarin iOS simulator but it fails on launch with a "The device {guid} was not found".
I have my environment settings like...
and when I run I see...
then...
researching the error, the recommendation is to explicitly set the XCode path which I have done, but I get the same error. Also, notice I am connected to our build Mac.
I have a coworker connected to the same Mac with the same computer and VS version I am on, and his iOS simulator works fine. I have uninstalled/reinstalled the simulator and restarted Visual Studio (2017RC).
I appreciate any pointers someone might have!
UPDATE
I reinstalled my Windows 10 OS thinking I had a corrupt install. Unfortunately on a clean machine with 2017RC, the simulator still fails in the same way as I described above.
In my case: UnCheck Remote Simulator to Windows
I am facing the same issue from last two days and solved this as well by removing the latest version of XCode 12.5.
Download the previous version of code i.e 12.4 from apple site and install
Move the downloaded xcode file in application and check on windows
It works fine
Latest version of XCode 12.5 is not stable
I confirm the issue is currently (May 2021) caused by Xcode 12.5 upgrade.
After I downgraded back to Xcode 12.4, the simulators started to work again with no problem.
I tried to upgrade Visual Studio for Windows to latest version 16.9.4, did not help. I launched Visual Studio Installer to reinstall Xamarin, did not help either.
Only when I removed Xcode 12.5 (using this shell script https://onexlab-io.medium.com/uninstall-xcode-from-macos-eca1b69dc836) and installed version 12.4 (from XIP archive from here How to download Xcode DMG or XIP file?) it started to work.
You may need to uncheck "Remote Simulator to Windows." I just fixed this issue for myself by doing so. However, I was trying to launch on the iOS simulator on my Mac side (running Windows vm via Parallels). It seems you might be trying to launch the simulator in windows.
If you need a quick solution, downgrade the version of VS and Xcode, for me this works:
VS 2019 - 16.9.3
Xcode - 12.4
Xamarin.iOS - 14.14.2.5
And for physical devices make sure Hot Restart is not enabled in Tools > Options > Xamarin > iOS settings
Just had the same problem after upgrading mac to Big Sur and Xcode 12.5 yesterday. Reboots and deleting obj/bin/.vs folders made no difference. The fix was to explicitly type the Xcode path into Xamarin options iOS settings - even though it was the default - untick Remote Simulator to Windows then pair/connect to mac from that options dialog. After closing the dialog and reopening it Remote Simulator was checked again. I unchecked it, closed the dialog and reopened it to check again - it was closed this time. All works fine now.
I also ran mac VS and let it update in the midst of all this.
I have the same issue since yesterday, to resolve that I uninstall the "Xamarin iOS simulator" and now it works...
it may be a solution for your issue!
Did you resolved the issue already?
I bumped onto the same issue today. I tried opening Xcode on Mac and it says it need to install additional tools. I let it install and try open/quit Visual Studio for Mac, Xcode, Simulator again (not sure if it is related)
Now to remote simulator works fine again.
I had the same issue and i resolved it by realizing that my PC with VS was on a different network than my Mac with Xcode. Once i put both machines on the same network the issue went away. Hope it helps.
I updated to Xcode 7 from the app store, but when I open Xcode the version still shows 6.2? 6.2 was my previous version. I also had to update my Mac OS from Mavericks to Yosemite in order to install Version 7 which I did.
Additionally, when I got the Apple Developer member center and click on Xcode version 7.0.1 it takes me to the app store and the app store update button states OPEN, but when I open the version states 'Version 6.2 (6C131e)' What's going on?
No idea what is actually happening, but this same thing happened to me. I tried enabling the Apstore debug menu and resetting things, but ultimately nothing i tried worked. I ended up uninstalling Xcode (just put it in the trash and empty) and installing fresh fixed it for me.
I had previously had the version 7 beta alongside App store Xcode (6.3 in my case), so maybe that is part of the problem?
I recently updated Xcode to version 6.4. In the App Store it says I have version 6.4 installed, but when I run Xcode it says version 6.3.2.
Does anyone know how I run Xcode version 6.4? Do I need to uninstall and then reinstall Xcode?
I installed it using the App Store and updated through the App Store as well.
So while I was unable to find out where Xcode 6.3.2 or 6.4 was installed on my mac, I uninstalled Xcode by dragging the application to the trash can and emptying it as recommended by Apple.
I then reinstalled Xcode 6.4 from the App Store and it appears to be working.
While it is a simple thing, I thought I would share as sometimes the simple solutions are the ones we don't think about.
