Xcode project not showing list of simulators

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.

1. Edit scheme
2. New scheme
3. 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.

回答4:

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5:

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.

回答8:

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9:

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)

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:

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12:

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..

1. Go to Window -> Devices

you can see all Devices and Simulators here

2. Just right click on any device or simulator
3. 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..

1. Change(degrade) the minimum deployment target of app to 8.3(not necessary)
2. restart xcode

It worked for me.. Hope will be helpful for someone later..

回答13:

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14:

check in your project's build settings , make certain you select Latest iOS (iOS 8.1).

回答15:

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16:

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17:

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18:

I had this happen to me after an update to a new Xcode. Running

xcode-select --install

fixed it for me.

回答19:

Just go to Xcode -> Window -> Devices

Click + at the bottom left

Add your new Simulator

回答20:

Quite Xcode and Open it again, it will show. For me it's worked.

回答21:

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22:

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23:

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24:

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25:

Check if in the app store under xcode it says GET instead of installed, delete your current version and get the new one

回答26:

I encountered this problem when I update my xcode to 8.2beta (with the app name xcode-beta.app), I found the answer above by Jeremy Huddleston Sequoia and tried to rename xcode-beta.app to xcode.app, it worked. I guess the name should be xcode.app to use the simulators, even if you didn't changed the name by yourself when you download the beta one.

回答27:

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28:

Click on Project name, it will list out three options which are Edit Scheme, New Scheme and Manage Schemes.. then click on New Scheme, you can see one dialogue box there you make sure your project is selected and click on OK after that you will see all simulators are back.
