Hi, I’m new to iOS, so sorry if my question might seem a bit obvious, but in the code below, should the conditional unwrapping happen before the DispatchQueue.main.async or after? just like what it is now?
Code:
DispatchQueue.main.async {
if let items = items {
self.items = items
self.tableView.reloadData()
} else {
print(“Unable to load data”)
}
}
Thank you in advance.
