Transfer Group Ownership

Transfer ownership of a CometChat group to another member using the iOS SDK.

AI Integration Quick Reference

// Transfer group ownership
CometChat.transferGroupOwnership(UID: "NEW_OWNER_UID", GUID: "GUID", onSuccess: { success in }, onError: { error in })

Note: Only the current group owner can transfer ownership. The owner must transfer ownership before leaving the group.

Transfer ownership of a group to another member. Only the current owner can do this, and since owners cannot leave their group, you must transfer ownership first if you want to leave. See Leave Group.

Transfer Ownership

Use transferGroupOwnership() to transfer ownership to another group member.

Parameter	Description
UID	The UID of the member to become the new owner
GUID	The GUID of the group

Swift

let uid = "cometchat-uid-2"
let guid = "cometchat-guid-1"

CometChat.transferGroupOwnership(UID: uid, GUID: guid, onSuccess: { (success) in
    print("Ownership transferred: \(success)")
}, onError: { (error) in
    print("Error: \(error?.errorDescription)")
})

On success, the new owner gets admin scope and the previous owner becomes a participant.

Real-Time Ownership Changed Events

Implement onOwnershipChanged() in CometChatGroupDelegate to receive real-time notifications when group ownership changes.

Swift

class ViewController: UIViewController, CometChatGroupDelegate {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        CometChat.groupdelegate = self
    }
    
    func onOwnershipChanged(group: Group, newOwner: GroupMember) {
        print("Ownership changed in group: \(group.name ?? "")")
        print("New owner: \(newOwner.name ?? "")")
    }
}

Set delegate in viewDidLoad(): CometChat.groupdelegate = self. Remove delegate when view is dismissed to avoid memory leaks.

Missed Ownership Changed Events

When fetching previous messages, ownership transfers appear as Action messages (a subclass of BaseMessage).

Field	Value/Type	Description
action	"ownershipChanged"	The action type
actionOn	User	The new owner
actionBy	User	The previous owner who transferred
actionFor	Group	The group where change occurred
