Xcode 项目未显示模拟器列表

Question

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?

Answer 1

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.

PS 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.

Answer 2

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 answer will help for someone.

Answer 3

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

Answer 4

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.

Answer 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

Answer 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.

Answer 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.

Answer 8

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.

Answer 9

Solution: Build Settings -> Architectures -> Supported Platforms: changed from iphoneos to iOS

Confirmed works in Xcode Version 9.0 (9A235)

Answer 10

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)

Answer 11

转到窗口，然后转到设备，然后按左下角的加号按钮添加设备并选择所需的模拟器。这对我有用。

Answer 12

检查项目的构建设置，确保选择最新的 iOS (iOS 8.1)。

Answer 13

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

Answer 14

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 :)

Answer 15

只需检查XCode支持与否的部署目标。

Answer 16

Deployment Target version change to a lower one helped for me:

Window -> Devices and Simulators -> Simulators. Check what are the latest versions of existing simulators.

Then go to your project's Target. Under Deployment Info, change Target to the version you saw the latest within your simulators. Mine was set to iOS 13.6 when the simulator was iOS 13.5 only.

Answer 17

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.

Answer 18

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..

Answer 19

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.

Answer 20

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

Answer 21

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.

Answer 22

如果您刚刚更新了 Xcode，您可能需要在模拟器再次可用之前重新启动计算机。

Answer 23

If you updated Xcode to 12.1. Completely quit Xcode and it will install components.

Answer 24

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.

Answer 25

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

xcode-select --install

fixed it for me.

Answer 26

Just go to Xcode -> Window -> Devices

Click + at the bottom left

Add your new Simulator

Answer 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.

Answer 28

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.

Answer 29

Lower the Deployment Target version. For example you have set the target as iOS 13.4 but your Xcode version is lower and there is no iOS 13.4 installed simulator.

Answer 30

我有同样的问题，从导入的项目生成，该项目的部署目标为 10.3，而我只安装了 10.0，将部署目标更改为 10.0 解决了我的问题。

Answer 31

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.

Answer 32

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.

Answer 33

I simply Renamed my Xcode file in Application folder to something else and renamed it back to Xcode.

Worked

Answer 34

Install iOS Simulator if you're missing one.

Answer 35

Nothing worked for me, except

gem install snapshot

fastlane snapshot reset_simulators

Answer 36

In my case I thought I created a new project using the iOS Framework template, but I inadvertently selected the macOS Framework template instead. This was preventing me from building the project for iPhone simulators. Deleting the project and recreating it, this time selecting the iOS Framework template, fixed the problem.

Answer 37

在xcode下的应用商店中检查是否显示GET而不是已安装，删除当前版本并获取新版本

Answer 38

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.

Answer 39

Nothing helped me so I downloaded the simulators for my deployment Target.

• Beside play button and target name where simulator is chosen,
• Click the simulator to see the simulator list window.
• Click on the last button is "Download Simulators"

• Download the simulators for your deployment Target

  You can check Deployment target :

• Below play button 1st tab ie Project navigator, Click it and click on Project name
• Select your target > General tab > Deployment Info > Deployment target.

Hope it helps

Answer 40

In my case the problem was in Architectures parameter. It was set to arm64 I just changed the value to Standard Architectures (arm64, armv7) - $(ARCHS_STANDARD) Then pod install

Answer 41

After trying a lot of suggestions, the below command solved the issue for me.

Try to restart the simulator service:

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService
