Parsing an array of JSON - Alamofire - Swift Forums Parsing an array of JSON Related Projects Alamofire json denniscmartin (Dennis Concepción Martín) April 2, 2021, 2:34pm 1 Hi there, Currently Im developing an app - while learning Swift and SwiftUI - that shows stock prices in real time. a JSON array is parsed as new unfrozen Starlark list. The unmarshalled data will be stored in a Dictionary object which you can use to access individual values as required. The decode function accepts one positional parameter, a JSON string. ![]() We can use the JSONDecoder class to decode this into. ![]() As an example, let’s say we have an array of numbers represented as a string: 1,2,3,4,5. This is done using the for-in loop in Swift. Decoding is done using the JSONDecoder class in Swift built-in support for JSON parsing. Here, were iterating through our array of blogs, and we know that blog is a dictionary of type String: AnyObject based on the type of our blogs array. When working with complex arrays, you’ll often need to loop through each element to get the values that you need. I am using it to determine which topic heading to place the song under in my list. I am using the following to iterate over all the songs: What Im having trouble with is accessing the topicIndex array. I am trying to parse a local JSON file but can't get it to work. For parsing JSON we need two functions that takes a String, and will parse and return an Array or Dictionary. Parsing JSON in Swift requires two steps: Decoding the data into an object, and mapping the object into a model. I have the following JSON file: As you can see I have an array within the array. Var employeeName: String! var employeeSalaryUSD: Int! var employeeSalaryEUR: Int! var employeeAge: String! let json = try! JSONSerialization.jsonObject(with: data, options.
