The playground crashes repeatedly, drops alerts, and jumps the insertion point (with loss of typed characters) to the top of the file. This will (I hope) be corrected in the beta that according to patten should be out week after next, but in the mean time it’s frustrating to read all the blogs on what people are delighted to find in Swift 2.0.
I hope someone has a workaround or a direction I can pursue.
I’ve already posted a forum question (https://forums.developer.apple.com/message/15886) and submitted a Radar (rdar:///21555545)…
Xcode 7.0b2, OS X 10.10.3 or 10.11b2; OS X playground, 10.11 SDK.
## Exception
It throws an exception, logged in Console.app as:
----
Unable to create target for stub executable.
unable to find executable for '/var/folders/2n/k51s3_gd2177vkrmy04p2s000000gn/T/com.apple.dt.Xcode.pg/applications/modeling-54310-7.app/Contents/MacOS/modeling'
----
/var/folders… usually contains an .app with a serial number one higher; 54310-8 in this case.
## Things that have no effect
Closing and reopening the project, with or without quitting Xcode or rebooting in between.
Closing the project and deleting the derived-products folder (or the project itself) from the Projects organizer.
Single or multiple pages. (I first saw this after I added a page, but if it persists after all these permutations, surely it’s a red herring.)
Deleting the directory in /var/folders, even as high as the child of /var/folders (it is restored, apparently in full, immediately).
Deleting ~/Library/Developer/ and ~/Library/Preferences/com.apple.dt*, logging out then in.
Copying source into a new project, then adding a playground.
Same results on 10.10.3 and 10.11b2
On and on, usual caveat that it’s impossible to ring the changes on _all_ the permutations. I guess I should try a reboot with the Shift key. I don’t knowingly install hacky .kexts (iStat Menus?), but if everything’s correct, then the bug doesn’t exist, right?
## Plea
Any suggestions on how I can get a working playground?
