You can use getDocuments() to fetch all documents in one collection or use .addSnapshotListener() to automatically fetch new documents.

Firestore.firestore().collection("Shops").getDocuments() { (querySnapshot, err) in
    if let err = err {
        print("Error getting documents: \(err)")
    } else {
        for document in querySnapshot!.documents {
            print("\(document.documentID)") // Get documentID
            print("\(document.data)") // Get all data
            print("\(document.data()["name"] as! String)") // Get specific data & type cast it.
        }
    }
}
