ios - CKRecord set parent error 4097 -

-

i'm trying set parent on ckrecord. basically, reminder child of list. list exists on server.

let record = ckrecord(recordtype: "reminder", recordid: recordid) let listid = ckrecordid(recordname: listname, zoneid: listzoneid) record["title"] = "test todo" record.setparent(listid) let modifyrecordsop = ckmodifyrecordsoperation(recordstosave:[record], recordstodelete:nil) modifyrecordsop.modifyrecordscompletionblock = { (_, _, error) in     guard error == nil else {          print(error)          return     } }

every time this, following error: [logfacilityck] got connection error operation 28174dd7caf85542: error domain=nscocoaerrordomain code=4097 "connection service named com.apple.cloudd" userinfo={nsdebugdescription=connection service named com.apple.cloudd}

if remove setparent line, record created on server. doing wrong?

it because listid record not yet saved cloud, therefore cloud cannot set listid parent of record. try saving both newly created records: 

let modifyrecordsop = ckmodifyrecordsoperation(recordstosave:[record, listid], recordstodelete:nil)

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
