VOODO File Template

An Xcode file template that will create your view, observable object, and data object all in one file with sample data.

You can then edit, delete or separate out parts if you want.

⚠️ Note: This template uses @Observable (iOS 17+).

👉For the ObservableObject template, go here.

How to Install

Add the VOODO.xctemplate to this directory: ~/Library/Developer/Xcode/Templates/File Templates/Custom/

(Click your home directory and then show hidden folders with COMMAND+SHIFT+. )

Note: That full directory might not even exist so you will have to create it.

In Xcode

Start Xcode and add a new file.
Scroll down until you see the Custom section and select VOODO:

Example Output

// View
import SwiftUI

struct PersonView: View {
    @State private var oo = PersonOO()
    
    var body: some View {
        List(oo.data) { datum in
            Text(datum.name)
        }
        .onAppear {
            oo.fetch()
        }
    }
}

#Preview {
    PersonView()
}

// Observable Object
import Observation
import SwiftUI

@Observable
class PersonOO {
    var data: [PersonDO] = []
    
    func fetch() {
        data = [PersonDO(name: "Datum 1"),
                PersonDO(name: "Datum 2"),
                PersonDO(name: "Datum 3")]
    }
}

// Data Object
import Foundation

struct PersonDO: Identifiable {
    let id = UUID()
    var name: String
}

You Are In Control

From here, you can:

Delete what you don't need
Keep all the parts in one file
Break out the parts into separate files
Change the template to use any naming convention you want
