I’m seeing an issue with CloudKit sharing in iOS 26.2.1: When I call CKShare(rootRecord:) with a brand-new record in a fresh custom zone, the share is created with no root attached (rootFromShare == nil). After saving both the root and share in a single CKModifyRecordsOperation, fetching the share from the server still shows no root reference (rootRecordID == nil). No errors are thrown, but sharing simply fails.
Key facts: • Custom zone created and confirmed (sharing enabled, capsRaw=7/15) • Brand-new record type and fresh IDs each run • Never reusing records or shares • Saving both root and share together in one operation • No default zone usage; always custom private zone
Tested: • Multiple devices, iCloud accounts, and app versions • Both simulator and physical device
Debug logs consistently show: • SHARE_CREATE_SHARE_LOCAL ... rootFromShare=nil • After save/fetch: rootRecordID=nil on server
Has anyone seen this? Is there a new CloudKit regression in iOS 26.x, or am I missing something subtle? Minimal sample project and full debug logs available if needed.
Any insights or workarounds would be hugely appreciated!
