Since updating to Sequoia & Xcode 16, I cannot run any code in a playground. Even the simplest code -
import Cocoa
print("Hello, world")
does not run and hangs on "Ready to Continue MyPlaground". I've tried restarting, force quitting, deleting and reinstalling Xcode, killing 'com.apple.CoreSimulator.CoreSimulatorService' in the activity monitor.
