]
}
]
}
However I need it to be returned like this:
"currentClasses": [
[
"name": "CATE27600A - 3 Mobile App Programming S1@CTEC",
"grade": 100,
"weight": 6,
"credits": 1
],
[
"name": "CATE36400A - 1 Prac News Prod 2 S1",
"grade": 91.48,
"weight": 5,
"credits": 1
],
[
"name": "ELA14300A - 4 AP English Literature S1",
"grade": 88.13,
"weight": 6,
"credits": 1
],
[
"name": "MTH45300A - 1 AP Calculus AB S1",
"grade": 79.4,
"weight": 6,
"credits": 1
],
[
"name": "MTH45310A - 4 AP Statistics S1",
"grade": 79.48,
"weight": 6,
"credits": 1
],
[
"name": "SCI43300A - 1 AP Environmental Science S1",
"grade": 94,
"weight": 6,
"credits": 1
],
[
"name": "SST34310 - 3 AP Economics",
"grade": 93.24,
"weight": 6,
"credits": 1
]
]
I have this structure made:
// MARK: - Welcome
struct Welcome: Codable {
let currentClasses: [CurrentClass]
}
// MARK: - CurrentClass
struct CurrentClass: Codable {
let name, grade, weight, credits: String
let lastUpdated: String
let assignments: [Assignment]
enum CodingKeys: String, CodingKey {
case name, grade, weight, credits
case lastUpdated = "Last Updated"
case assignments
}
}
// MARK: - Assignment
struct Assignment: Codable {
let assignment: String
let category: Category
let dateAssigned, dateDue, score, totalPoints: String
}
enum Category: String, Codable {
case majorGrades = "Major Grades"
case minorGrades = "Minor Grades"
case nonGraded = "Non-graded"
}
I need specifically the grade, weight, and credits to be returned as a Float for all of the classes.

Your structs define those values as type String :
let name, grade, weight, credits: String
Simply change the appropriate variables to be of type Double and they will be outputted how you want.
let name: String
let grade, weight, credits: Double
