How to Fix "Xcode Simulator Not Launching"
If the Xcode simulator is not launching, it may be due to misconfigured settings, system resource issues, or outdated software.
Here’s how to resolve it: First, check if there are any issues with the simulator device itself.
Go to Xcode > Open Developer Tool > Simulator and try manually launching the simulator.
If the simulator does not start, try restarting Xcode and your Mac to resolve any potential issues with system resources.
Another reason the simulator may not launch is insufficient system resources.
Make sure your Mac has enough free memory and CPU power to run the simulator.
If necessary, close other applications to free up resources.
If you're encountering the issue with a specific device, try resetting the simulator.
In the Simulator app, go to Device > Erase All Content and Settings, which will reset the simulator to its default state.
You can also try deleting and recreating the simulator device by going to Window > Devices and Simulators, selecting the device, and clicking the + button to add a new one.
If the issue is related to outdated or incompatible software, make sure that both Xcode and your macOS are up-to-date.
Check for updates in Xcode by going to App Store > Updates and install the latest version of Xcode and macOS updates.
Outdated simulator components can cause issues as well, so make sure your simulator’s device and iOS version are properly matched.
You can check this by going to Window > Devices and Simulators and verifying that your simulator is using the correct iOS version.
If you’re still having trouble, reset the Xcode preferences by going to Xcode > Preferences > Locations and click on Reset to restore default settings.
Lastly, you can try using the terminal to launch the simulator manually.
Run the following command in Terminal: xcrun simctl boot <device> followed by xcrun simctl launch booted <your-app-id> to see if the simulator works via command line.
After these steps, your Xcode simulator should launch properly.
