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

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.
