New programmer here! I'm working with a network request and below is a snippet of my code. After I complete the network request I want to store a value from the request into a variable. However, when the variable is called outside of the if let statement it is NOT updated. Essentially, the print statement inside the if let statement prints the value I'm looking for, but the print statement outside of the if let statement prints the default value I set for that variable. The variable is global. I need to use that updated variable elsewhere in my code, any ideas?
if let data = data
self.nameLabel.text = data.name
person = data.name
print(person)
print(person)

You don't show enough context. Most likely yourprintis outside of the async completion block.

First of all you didn't showed complete code so I am guessing you need main queue to update your UILabel first as shown in below code:
DispatchQueue.main.async
self.nameLabel.text = data.name
next thing is if you want to access the value somewhere else once your request completes and UILabel updated then you can get the value from it this way:
let value = self.nameLabel.text!
And if you want to access the value once request complete then you can use closure and HERE you can check example of it.
