# init(share:container:)

Initializes the CloudKit sharing view controller with a CloudKit share record and container to manage participants and restrictions.

## Declaration

```swift
init(share: CKShare, container: CKContainer)
```

## Parameters

- `share`: An instance of doc://com.apple.documentation/documentation/CloudKit/CKShare that was previously saved.
- `container`: An instance of doc://com.apple.documentation/documentation/CloudKit/CKContainer that contains the record that is shared.

## Discussion

Discussion Use the init(share:container:) initializer method to create the UICloudSharingController instance when the user who owns the CKShare record wants to manage the participants and restrictions associated with the share. (For more information, see Adding and removing participants from an existing share.) You also use this initializer method when users are participants who want to remove themselves from a share. (For more information, see Viewing participants and leaving a share.) important: You must initialize the controller with the correct initializer method. Do not use init(preparationHandler:) if the CKRecord is already shared. Likewise, do not use init(share:container:) if the CKRecord is not shared. Using the wrong initializer leads to errors when saving the record. init(share:container:) requires a reference to the CKShare instance associated with the CKRecord instance that represents the shared data. To retrieve the CKShare instance, get the share property value (a CKRecord.Reference instance) from the CKRecord instance. Then pass the recordID from the CKRecord.Reference instance to the fetch(withRecordID:completionHandler:) method on a CKDatabase instance, as shown in the following code. CKRecord *record = [self record]; CKReference *shareReference = [record share]; if (shareReference == nil) {   return; } CKContainer *container = [CKContainer defaultContainer]; [[container privateCloudDatabase] fetchRecordWithID:[shareReference recordID] completionHandler:^(CKRecord * _Nullable record, NSError * _Nullable error) {      if (record == nil) {     NSLog(@"%@", [error localizedDescription]);   } else if ([record isKindOfClass:[CKShare class]]) {     CKShare *shareRecord = (CKShare *)record;     NSLog(@"%@", [shareRecord URL]);   }    }];
