Error running playground. Unable to find suitable target device. (iOS Swift)

Question

I created a new project in XCode.

File > New > Playground (option+shift+cmd+N)

Answer 1

Fox Xcode 7, I had to install iPad Air or iPad Air 2 for the playground to work.

Answer 2

From the developer forums, this worked for me:

1. Quit Xcode
2. Delete the folder /Users/<username>/Library/Developer/CoreSimulator/Devices. For example, in Terminal: rm -rf ~/Library/Developer/CoreSimulator/Devices
3. In Terminal: killall -9 com.apple.CoreSimulator.CoreSimulatorService (or just reboot).

Answer 3

As referred by @Mayank Gupta , It worked on adding new simulator and restarting the XCode.

Answer 4

Try navigating to the Xcode Menu Window >> devices (shift+cmd+2) a new window will pop up.

On the bottom left, add a new simulator, specifically one running on iOS 8.0 to the existing list.

Restart Xcode.

Answer 5

Another possible way to encounter that issue is to get Xcode being auto-updated, while the simulator was launched.

The solution is like mentioned above but more polite:

1. Quit Xcode and Simulator app
2. Run in Terminal: killall -9 com.apple.CoreSimulator.CoreSimulatorService
3. Launch Xcode and find that all fixed now.

Sure, you can just reboot instead.
