I've also searched the same and found some like below. Using a Fetch Request to Collect all objects and delete one by one.

var arr: [AnyObject] = managedObjContextIns.executeFetchRequest(fetchReq, error: &error)
for managedObj: NSManagedObject in arr 
{
  managedObjContextIns.deleteObject(managedObj)
}
var error: NSErrorPointer? = nil
managedObjContextIns.save(&error)

Hope it helps.

Upvoted :) Good solution. I would check the error at the end, and also instead of var arr: [AnyObject], I would cast it to the type of entity it is, e.g. Register (assuming that register inherits from NSManagedObject)
