How to run Swift Standard Library playground in Xcode 7?

Can anyone suggest what I need to do to get the new Swift Standard Library to run with Xcode 7 beta on OS 10.10.3 (i.e. _not_ 10.11 beta)?


I consistently get "Unable to find a suitable target device" as soon as I go to a playground page with executable code in it. Prompted by a Stackoverflow suggestion for a previous version of Xcode, I have tried creating an iOS 9 simulator device, but that has not solved the problem. Unlike a full-fledged project, a playground does not seem to have any way of attaching it to a device, real or simulated.

... just to be clear my problem is with running the Swift Standard Library _playground_, i.e. the recently released sample code, not the Library itself!

I had this problem until I rebooted my system after installing Xc7

I don't have any suggestions, but just FYI...


I am also running 10.10.3 and XCode 7 beta (7A120f), and I downloaded the Swift Standard Library playground sample and it seems to work fine (although it did take some time to compile and run each page as I switched between them).


So the problem isn't just specifically being on 10.10.3.

Thanks for the suggestion. I tried it, but the problem remains for me.
