Invalid device status - Xcode / iOS simulator error

Question

Problem: I cannot simulate the interface of an Apple watch. Whenever I try to test the Apple Watch application on the iPhone 6 simulator, Xcode successfully terminates and creates the application, tries to open the simulator and crashes with an error message that says “Device status is incorrect”.

I believe that the simulator has a clock simulator that opens with compatible iPhone models for simulators that can communicate with Apple watches (for example: iPhone 6). Although I have not seen it work. I built a universal interface for the iPad and iPhone, and the other for the watch, so this is not an application issue for the wrong device. Whenever I test my real iPhone, I can successfully test the universal interface.

I am using Xcode 6.2 for iMac OS X 10.10.3

I tried restarting Xcode / Computer. It seems that I can not find any other mention of the status "Invalid device" anywhere, I hope, due to the fact that this is an obvious thing to avoid / fix that I missed. Any help would be appreciated.

Answer 1

Force Quit xCode and reboot will fix the problem.

Answer 2

I ran into this problem after upgrading Xcode 6.4 to 7.1. The following are the fixes for this:

• Clear the project (cmd + shift + k), as well as the clean build folder (CMD + Shift + K + option)

2. Exit the simulator and run again.
3. Close Xcode and Simulator and run again
4. Reboot the Mac .

Solution 3 worked for me!

Answer 3

I had the same problem. This is usually because you are simply updating Xcode or changing your name in the Applications folder.

If you just restart your computer, it will work correctly.

Hope this helps!

Answer 4

I noticed that this happens when more than one Xcode application is installed.

To fix this,

• Launch Xcode and click the preference button ..,
• Click the Location tab, select the correct options from the Command Prompt drop-down menu.
• Close Xcode and restart it.
• Launch the app.

Answer 5

First of all, just clean the project.

1. Exit your project .
2. Exit your Xcode .
3. Restart Xcode .

This happens to me when two different versions of Xcode work for me at the same time. Hope this helps you.

Answer 6

No need to stop, restart, or even reinstall. Switch to another iOS Simulator device (6s if you used 6s plus) and voila!

Answer 7

Nothing worked for me on Xcode 7.3.1.

You will have to reinstall it to make the simulator work.

• Go to the application folder. Drag Xcode to Dustbin.
• The contents of an empty trash can.
• Go to the App Store and install Xcode.
• Launch Xcode. Now the simulator should work.

Answer 8

I have Xcode 7.3 and Xcode 8.0 installed.

If I work with Xcode7.3 and open Xcode8.0 to get the code from the Xcode8.0 project.

When I run my application on Xcode7.3, it will give me the same error.

The solution is a simple ForceQuit or closes all Xcode and opens the required file.

Answer 9

In my case, the simulator will show an undefined black screen, whether to try to start the project or run the simulator directly (which should lead you to a simulated initial screen). This will happen even on a newly created simulated device.

After the existing sentences didn't work, the following worked for me:

• Delete simulator
• Remove Xcode
• Delete Developer Folder
• Reinstall Xcode from the app store. This requires a second attempt to start Xcode so that Mac OS realizes that it is no longer installed.

Answer 10

Jus will clear the project and restart Xcode. This happens to me when I have two versions of xcode working with different versions at the same time.

Answer 11

Reliable fix Just close your xcode and run it again, hope this helps you. That damn works for me.
