Core Data Relationship data not being saved

I have two entities. ent1 and ent2 and one to many relationship between them. 

let ent1 = NSEntityDescription.insertNewObjectForEntityForName("Ent1", inManagedObjectContext: managedObjectContext) as! Ent1

ent1.a = "aaa"
ent1.b = "bbb"
ent1.ent2?.info = "info"

do{
    try managedObjectContext.save()
} catch let error {
    print("Core Data Error : \(error)")
}

The problem is that only ent1 is being populated and ent2 remains empty.

EDIT:

I tried doing like @Amruta mentioned. And now I'm getting duplicates in my ent2. I would like to have 10 values in ent2, and thousands in ent1. Is that possbile?

You will first need to insert the ent2 in the same way as ent1

 let ent2 = NSEntityDescription.insertNewObjectForEntityForName("Ent2".....

 ent2.info = "Info"

then,

 ent1.ent2 = ent2

than call the save
