问题
I open my project in Xcode 6.1. When I try to run the project, the button is grayed out. When I try to go to Product > Clean, the option is grayed out. When I look at the list of simulators, all I get is My Mac instead of the usually iOS Device. How do I get my simulators to come back?
回答1:
Click on the project name (Right to the Run button). Three options will appear.
- Edit scheme
- New scheme
- Manage scheme
You can click on "New scheme" and then click on "OK" in popup window.
You will have simulators list back.
回答2:
Make sure that the project you are trying to run has deployment target equal to or less then the SDK version of your Xcode. In my case I tried to run a project which was built using iOS8.4 but I have Xcode6.1 with SDK version 8.1
I changed the deployment target to 8.1 and it start showing me simulators.
P.S before doing this, make sure that your code and external libraries are compatible with your new deployment target, else you have to update your Xcode.

Try This, It worked like a charm! for me,
Follow below step
1) Clean Derived Data as show below,
rm -rf ~/Library/Developer/Xcode/DerivedData/
OR
Xcode---> Preferences--->Location--->Derived Data
2) In Deployment Info change Deployment Target
It's equal to or less then the SDK version of Xcode
3) Quit Xcode
4) Reopen Xcode you will see list of simulators
Hope this is help for some one.

I could not find any solution that would fix my issue. All simulators were there for all projects but the one that I needed them.
Solution:
Build Settings -> Architectures -> Supported Platforms:
changed from iphoneos to iOS
回答5:
Also check the iOS Deployment Target under build settings. I was using Xcode 6.3 while the deployment target was set to iOS 8.4. I got the list of simulators as soon as I set it to iOS 8.3
回答6:
Cmd below solved my problem:
$ sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
In my case, I upgraded to Xcode 8 and downloaded another version 7.3.1 later (renamed it to "Xcode 7.3.1"), then cannot get the simulator list in Xcode 8.
回答7:
In my case i'd accidentally deleted ios devices in system Finder -> Library->Devices->Core simulator
So, the simulators are not listed in the Xcode project except ios device.
I solved this by adding ios simuulators from Xcode->Window->Devices->Add simulators
Hope it'll help someone.

If you renamed Xcode.app since first launch, the iOS Simulator becomes unavailable. This is mentioned in the Xcode 6.1 Release Notes:
Renaming Xcode.app after running any of the Xcode tools in that bundle may cause iOS Simulator to be no longer be available. Either rename Xcode.app back to what it was when first launched or restart your Mac. (16646772)

Go to Window then Devices and press the plus button at the bottom left to add a device and select the simulator which are required.This worked for me.
回答10:
Solution: Build Settings -> Architectures -> Supported Platforms: changed from iphoneos to iOS
Confirmed works in Xcode Version 9.0 (9A235)
回答11:
Sometimes the simulator you have might not be the simulator specified in Build Settings. Make sure that simulator package is downloaded for your IOS Deployment Target
回答12:
If Your problem is due to multiple (versions of) xcode
Then follow following steps
1. Cleaning Derived Data
Go to Xcode preferences -> Select location tab -> select little gray arrow on /Users/apple/Library/Developer/Xcode/DerivedData. You will be redirect to folder From there select Derived Data folder and Delete.
2. Completely Quite The Xcode and reopen
This will solve your problem. Happy coding :)
回答13:
check in your project's build settings , make certain you select Latest iOS (iOS 8.1).
回答14:
I still had my iOS Device, but all my simulators were gone.
I tried every suggested solution I could find on stackoverflow.
Eventually, I deleted the Xcode app and downloaded it again from the App Store. After installation, the simulators were back.
回答15:
Looks like Xcode hides that menu when the window is a certain size. You have to make your window quite large before it comes back.
回答16:
Same Problem happened with me.. When I updated from Xcode 8 Beta 3 to Xcode 8 Beta 4, But I resolved it by this way..
- Go to Window -> Devices
you can see all Devices and Simulators here
- Just right click on any device or simulator
- Tick on Show in Destination Menu (Even it is already checked, then click it twice, It may be refresh things)
If above does not work.. as if you do not see any simulators, then..
- Change(degrade) the minimum deployment target of app to 8.3(not necessary)
- restart xcode
It worked for me.. Hope will be helpful for someone later..
回答17:
Small but a effective solution. In my case i updated to my xcode to 9.2 version and simulators disappeared.
I found this solution and it worked for me and for others also.

Just quit your xcode and restart again. You will have simulators.

回答18:
For those coming from Unity, even if you manage to make them show up (by changing Build Settings > Supported Platforms to iOS it would not run in the simulator.
Instead, you need to select this Simulator SDK :
And make sure something other than Metal exist.
Then the simulator device list will be there from start.
回答19:
I ran into another situation where this can occur. I work with a team we use Xcode server for continuous integration. The server wasn't seeing any simulators, but only for one project. I eventually determined that this was due to the fact that the version of Xcode on our server was one release earlier, and the Xcode project was set to build to the newest version available. Simply updating Xcode solved the issue for us.
回答20:
I had this happen to me after an update to a new Xcode. Running
xcode-select --install
fixed it for me.
回答21:
Just go to Xcode -> Window -> Devices
Click + at the bottom left
Add your new Simulator
回答22:
Quite Xcode and Open it again, it will show. For me it's worked.
回答23:
If you just updated Xcode, you may need to restart your computer before simulators become available again.
回答24:
After upgrading to Xcode 10.3, the list of simulators was empty. I rebooted and it was resolved.
This doesn't necessarily answer the OP's specific question, but this was the first place I ended up in researching my Xcode 10.3 upgrade issue.
回答25:
I had the same issue, generated from an imported project, the project had 10.3 as deployment target and I only had 10.0 installed, changing the deployment target to 10.0 solved my issues.
回答26:
For anyone struggling with this, I tried the mentioned options without success. Turns out all I needed to do was just quit and relaunch Xcode. Simple things can be annoying sometimes.
回答27:
In my case I had created a static library target for tvOS in Xcode 8.3.3, and the tvOS simulator was not showing up in the list. Eventually found out that TARGETED_DEVICE_FAMILY in the Build Settings was set to 1,2 instead of 3. Leaving this here incase anyone else encounters the same problem.
回答28:
I just needed a good, old fashioned restart the computer. When uninstalling and reinstalling XCode didn't do the job, I restarted out of pure frustration....lo and behold! After a restart, everything was as it should be.
回答29:
I simply Renamed my Xcode file in Application folder to something else and renamed it back to Xcode.
Worked
回答30:
Install iOS Simulator if you're missing one.
