Hi guys, I'm trying to develop my first app, but have a coding problem I can't seem to solve despite searching through forums and SwiftUI tutorials. I'm building a radiology teaching app and need to sort different pathology and anatomy into different categories, depending on the imaging study. I thought I could solve this by using multiple dictionaries but encounter an error when I try to use more than one Category declaration. I tried subdividing the items into sections and listing them as arrays in JSON data format, but this did not work either. "var chests: [Chest] = load("chest.json") var chestcategories: [String: [Chest]] { Dictionary( grouping: chests, by: { $0.category.rawValue } ) }" "[ { "id": 0, "chestname": "Heart", "chestimage": "heart", "category": "anatomy", "description": "Size, Shape, Margins", "sectioncategory": "Chest" },

{
    "id": 1,
    "chestname": "Lungs",
    "chestimage": "lungs",
    "category": "anatomy",
    "description": "Airspace opacity, Pleural effusion, Pneumothorax",
    "sectioncategory": "Chest"
},

{
    "id": 2,
    "chestname": "Airway",
    "chestimage": "airway",
    "category": "anatomy",
    "description": "Caliber, Narrowing (Symmetric vs Asymmetric), Tracheal deviation",
    "sectioncategory": "Chest"
},

{
    "id": 3,
    "chestname": "Diaphragm",
    "chestimage": "diaphragm",
    "category": "anatomy",
    "description": "Is there air under the diaphragm?, Diaphragmetic hernias or defects, Shape (Right hemidiaphragm should be higher than left)",
    "sectioncategory": "Chest"
},"

In this example, I'd like to be able to sort and selectively display data based on both the category and sectioncategory variables. Thanks guys!
