I’ve got a do-catch, like for example this one:
do {
let jsonData = try Data(contentsOf: jsonUrl!)
let jsonDecoder = JSONDecoder()
let modules = try jsonDecoder.decode([Module].self, from: jsonData)
} catch {
print(error) // Where does the error-object come from?
}
This code works. If the parsing fails, then the error-object is printed to the console.
But where does the error-object come from?
The error-object is available in the auto-completion. But it’s nowhere declared and assigned a value.
