Why is my playground project taking so long to launch simulator?

When I run a playground project, it says "Launching simulator" and takes a very long time. What could be the problem?

A common complaint with the simulator. Try deleting derived data.


Still no joy, walk thru the comments in this SO thread: https://stackoverflow.com/questions/39978092/xcode-playground-gets-stuck-on-running-playground-or-launching-simulator-and

Hi ShinehahGnolaum


You ticked the reply from KMT but it had 2 parts, which bit worked, deleting derived data or the stack overflow thread?


Thanks

I didn’t really look at the link but I did delete derived data. But it didn’t help.

were you able to solve this issue? I think I was having the same problem like you but in a different way, it seems that simulator was running in the background but when I go to xcode -> simulator it opens and then show the simulator and afterwards it close it but the Iphone sim is executing in the back. I am not able to even keep it open so when it opens I just close it with Cmd + W just to don't lose too much resources of my machine :s. what did you do? did you solve it your issue?

I just open the playground, tell it to run, and do something else and forget about it until I need to try some code in it.
