I've noticed that on some of our CI Macs lots of Disk space is being used up by some strange folders in $TMPDIR. The folders in question are ~3gb and Prefixed with "Deleting-" e.g. Deleting-9B82497C-17FC-4A52-B230-404B3D74FA3A Deleting-64B237FE-B629-4C28-8ED8-1BFBB0E91801 Deleting-D514B888-6030-4875-8AC3-1023E8B856AD Deleting-532C128D-14E1-464B-8453-3B37645EF36C Each one looks like a iOS home folder in structure. The space is reclaimed only when the Machine is rebooted. Any ideas? thanks

Note: this has only begun to manifest with Xcode 11 GM (Seed 1 + 2) - it has not certainly not been a problem any of the later betas.App and tests continue to succeed as expected on physical iOS 13 GM devices and on older simulators (12.2) through Xcode11. Problem seems to be localized to the iOS 13 simulators.`SecKeyCreateRandomKey` returns the key, without error but the Key is not stored as expected.Console immediately outputs the following:default item 14:03:11.835391+1000 com.apple.securityd insert failed for item <keys,rowid=null,cdat=2019-09-17 04:03:11 +0000,mdat=2019-09-17 04:03:11 +0000,kcls=1,labl=null,alis=null,perm=1,priv=1,modi=1,klbl=71BBCB041C9C39754ADACF6A79F8440AB96A866C,atag=636F6D2E61746C61737369616E2E6D6F62696C656B69742E73656375726974792E44656661756C744B6579416C696173,crtr=0,type=73,bsiz=256,esiz=256,sdat=2001-01-01 00:00:00 +0000,edat=2001-01-01 00:00:00 +0000,sens=0,asen=0,extr=1,next=0,encr=0,decr=1,drve=1,sign=1,vrfy=0,snrc=0,vyrc=0,wrap=0,unwp=1,agrp=AAAAAAA.com.foo.bar,pdmn=dku,sync=0,tomb=0,sha1=947C7C477EE39951793FCF497D5E585A5D497363,vwht=null,tkid=null,v_Data=<?>,v_pk=B32B2325BBB584B0D1D3BA8D8EAA54465DB2FCCC,accc=3137300B0C0470726F740C03646B7530280C0A6B414B534B657941636C311A30180C136B414B534B65794F7044656661756C7441636C010101,u_Tomb=null,musr=,UUID=02207EB8-1A49-4FAB-9D2D-264C67FFC5FB,sysb=null,pcss=null,pcsk=null,pcsi=null,persistref=> with Error Domain=NSOSStatusErrorDomain Code=-25330 "(null)" UserInfo={-25330=(({length = 57, bytes = 0x313 securityddefault SecWarning 14:03:11.835606+1000 com.apple.securitydandAuthentication is needed AppNameButTruncated[16208]/1#9 LF=0 add Error Domain=NSOSStatusErrorDomain Code=-25330 "(null)" UserInfo={-25330=(({length = 57, bytes = 0x3137300b 0c047072 6f740c03 646b7530 ... 6c744163 6c010101 },""))} securitydKey is not returned in subsequent get querires.As a workaround, If I manually store the key, immediately after creation, using `SecItemAdd` it's behaves as expected.It'd be great to get some guidance on this, thanks
