Working with optionals in swift?
Example:
var name: String?
print(name)
In Swift, variables can be declared as 'Optionals', which means they can hold a value or be nil. The above code will print 'nil'.
Solution:
var name: String? = "ChatGPT"
if let unwrappedName = name {
print(unwrappedName)
}
By using 'if let', you can unwrap the optional value safely and use it.
