Fire an action once a transaction ends - sqlite

Question

I'm using Stephen Celis iOS lib for handling SQLite3 databases, here is the github link.
Taking the example on the git :
try db.transaction {
let rowid = try db.run(users.insert(email <- "betty#icloud.com"))
try db.run(users.insert(email <- "cathy#icloud.com", managerId <- rowid))
}
// BEGIN DEFERRED TRANSACTION
// INSERT INTO "users" ("email") VALUES ('betty#icloud.com')
// INSERT INTO "users" ("email", "manager_id") VALUES ('cathy#icloud.com', 2)
// COMMIT TRANSACTION
I tried to implement the commitHook block but it is fired for each insert. I'd like to fire an action only when all the requests are sent :-D
What should I do ?
Cheers
Edit :
Here is how I implemented the commit hook.
for bay in list{
try! self.themanager.db.transaction {
try! self.themanager.db.run(self.themanager.bays.insert(
//insert values
))
self.themanager.db.commitHook({
print("end commit hook")
})
}
}
Maybe it's related to my main loop :/

From SQLite TRIGGER docs:
At this time SQLite supports only FOR EACH ROW triggers, not FOR EACH STATEMENT triggers. Hence explicitly specifying FOR EACH ROW is optional. FOR EACH ROW implies that the SQL statements specified in the trigger may be executed (depending on the WHEN clause) for each database row being inserted, updated or deleted by the statement causing the trigger to fire.
Commit hooks work like triggers. Unfortunately, the "FOR EACH STATEMENT" behavior is not supported yet.
