I've also encountered this problem in my own framework ColorKit
I downloaded a 450000 line JSON database from GitHub and found out it has no id while my SingleColor model is Identifiable
AHHHHH
So I went to to add id to them one by one for a couple of days and realized I could actually create a struct that's without the id called the SingleColorInit and load the JSON into this model and then casting all of my data into my SingleColor model.
Code:
public struct SingleColorInit: Codable, Hashable{
public var name: String
public var hex: String
public var rgb: RGBList
public var hsl: HSLList
public var luminance: Double
}
public struct SingleColor: Codable, Hashable, Identifiable{
public var id: UUID = UUID()
public var name: String
public var hex: String
public var rgb: RGBList
public var hsl: HSLList
public var luminance: Double
}
let coloKey: [InitColor] = load("database.json")
public func database() -> [SingleColor] {
var returnData: [SingleColor] = []
for datum in colorKey {
returnData.append(SingleColor(name: datum.name, hex: datum.hex, rgb: datum.rgb, hsl: datum.hsl, luminance: datum.luminance))
}
returnData.remove(at: 0)
return returnData
}
so when I create a new instance of the object the UUID will be generated.
In your case you can do this:
struct InitReminder {
var title: String
var dueDate: Date
var notes: String? = nil
var isComplete: Bool = false
}
struct Reminder: Identifiable {
var id: String = UUID().uuidString
var title: String
var dueDate: Date
var notes: String? = nil
var isComplete: Bool = false
}
// load your data (I use the load method in Apple's SwiftUI tutorial)
let reminders: [Reminder] = load("youdatabase.json")
func database() -> [Reminder] {
var returnData: [Reminder] = []
for datum in reminders{
returnData.append(Reminder(title: datum.title, dueDate: datum.dueDate, notes: datum.notes, isComplete: datum.isComplete))
}
return returnData
}
And then I realized...
When you use your data in a SwiftUI(if you use it) List or ForEach, you don't need it to be Identifiable; use each item's self as the id. Just do this:
List(yourData, id: \.self) { item in
...
}
ForEach(yourData, id: \.self) { item in
...
}
This is problem has annoyed me long time really😂 I'm really happy to share this solution to someone who need it
It's really annoying
hope it'll help
