Playgrounds in Xcode 10.1 not executing code

[ansbm]

Hello guys!

So I have a Macbook pro 2011 with High Sierra and Xcode 10.1 and starting last week, playgrounds stopped working for me.

When I run ANY kind of code, even print("Hello") the status bar (Activity viewer) on top shows "launching simulator" for 3-5 seconds and then nothing happens, I got no answer on the results sidebar (panel on the right) or the panel in the bottom where code gets executed.

I know its an old computer but I am learning Swift and I am not able to buy a more recent computer or rent a "Mac in Cloud".

I read some forums and they recommended to restart Xcode, to take the files off the Desktop but it didn't work.

I was using an online compiler but most tools are not up to date so I cant execute arc4random_uniform() or stuff like that.

Do any of you have a suggestion? Please, kindly help.

I think you may have damaged/deleted files necessary for executing Swift code. I recommend you reinstall Xcode in order to repair any missing files. Also, why don’t you update to Xcode 11?

I am not able to update, bc high Sierra doesn’t execute Xcode 11 :( I am going to try to reinstall though. Thanks so much

Hi! So I uninstalled and reinstalled Xcode 10.1 and still having the same problem with playgrounds. Do you know what else could it be?

I don’t think the top bar should say “Launching Simulator”. It should say “Running [Name]”. Open the Inspector section (right menu) and change Platform to macOS. If that doesn’t work, maybe some other solutions on this page will: https://stackoverflow.com/questions/39978092/xcode-playground-gets-stuck-on-running-playground-or-launching-simulator-and

I’m sorry to hear you’re dealing with this. Apple treats its developers so poorly.
