I think you should see the upcoming video, “The Learning App” in December. That way, you should have plenty of time, and then learn JSON. Look here: Module 5: Learning App
Go To CodeWithChris, and then click on iOS Foundations (SWIFTUI) and then click welcome, and release schedule in CodeWithChris, it should be coming soon
