Is this possible ? ...
static func loadJSON<T>(_ url: URL, arrayType: T.Type)
let json_array: [AnyObject] = try JSONDecoder().decode(Array<T>.self, from: json_data)Trying to make my loading func a bit more dynamic.
The code should work as expected (though it is not clear enough what you expect) only if `T` is `Decodable`:
static func loadJSON<T: Decodable>(_ url: URL, arrayType: T.Type) {
do {
let json_data = Data()
//...
let json_array: [T] = try JSONDecoder().decode(Array<T>.self, from: json_data)
//...
} catch {
print(error)
//...
}
}But what do you expect with this code? Generic parameters are resolved statically and it may not be so dynamic.

Works with <T: Codable> thank you. 🙂
