ios - Playgrounds broken in Xcode 8.3 -


since started working xcode 8.2 (and 8.3 lately), playgrounds broken me.

when opening playground see message "failed launch process. error returned in reply: connection interrupted"

complete re-installation of xcode or removing / re-creating /private/tmp folder (as suggested other posts) did not help.

did encounter similar problem? there other known work-arounds? (http://www.openradar.me/31296836)

here sample output coresimulator.log

note creator of timing: issue no longer occurs of timing 1.8.1 , timing 2.0.

ios playgrounds work ok in xcode 8.3.x on macbook, got launching simulator errors on mbp. macbook travelling, has minimal set of apps. in particular, has fewer app icons in status menu bar.

so on mbp, quit of aren't on mb, , hey presto, playgrounds ran! started apps 1 one, , timing brought launching simulator error — closing menu bar icon fixed again, though timing app still running.

not picking on timing especially; quick-access app in menu bar.

before this, had reinstalled sierra, not clean install. would've been next step.
