I'm using the Mapper library with Swift for JSON.
To get it into a variable you do something like:
try firstName = map.from("first_name")
With autocomplete I can see the result of map.from
is a value of type T
which is a generic I think.
I want to add a nilIfEmpty
method like map.from(value).nilIfEmpty()
so that if the json is just ""
I'll have it be nil. It's a lot more compact than map.from(value) == "" ? nil : map.from(value)
map.from(value) == "" ? nil : map.from(value)
How would I write this though?
You could just extend String
:
extension String {
func nilIfEmpty() {
return self.isEmpty ? nil : self
}
}
map.from(value).nilIfEmpty()
