Xcode Playground Failed to launch

Question

I can't run any Xcode Swift Playground project without getting the error:

Failed to launch process. Failed to attach to stub for playground execution: error: attach failed ((os/kern) invalid argument)

Does anyone know how to solve this?

Answer 1

I've the same issue. If I launch Xcode using rosetta, it doesn't show anything. You must switch off rosetta and it works perfect.

Predetermine

are there any other solution, i way to lazy switching from rosetta and not everything I switch from muy prod app and personal app/exercise – Disparate

@Disparate yes, you can have multiple Xcodes. They may even be the same version of Xcode. Just rename the binary. Download from developer.apple.com and not the app store. – Charmainecharmane

Answer 2

To expand on @E.P's answer

To put off rosetta Go to Aplications-->Xcode-->Get info --> Uncheck rosetta.
You need to restart the system in some cases

Answer 3

Right click on Xcode, Get Info, Uncheck Rosetta. Then quit Xcode from Dock and re open your playground file.
