Two examples of iterating over a list of elements, with ForEach. See bellow how to add a PickerView

ForEach example + PickerView.swift

import SwiftUI

struct ContentView: View {

    let tips = ["Dream of mice", "Make some Origami", "Get the dog juggling", "Eating candies", "Sniffing weird stuff"]

    var body: some View {
    // Simple iteration where there list contains only a bunch of Strings
            ForEach(tips, id: \.self) { tip in
                VStack {
                    Image("Meditate")
                        .resizable()
                        .scaledToFit()
                    Text("Cat relaxation tip: \(tip)")
                }
            }
            
    // More complex iteration over a list of instances
        VStack {
            ForEach(RelaxationTip.demoTips) { tipModel in
                VStack {
                    Image(tipModel.imageName)
                        .resizable()
                        .scaledToFit()

                    Text(tipModel.tip)
                }
            }        
        }
    }
}

// Here is the list of instances. Remember: It is mandatory that the Model conforms to Identifiable protocol, so each instance can be identified by an unique identifier

import SwiftUI

struct RelaxationTip: Identifiable {
    var id = UUID()
    var imageName: String
    var tip: String
}

extension RelaxationTip {
    static let demoTips: [RelaxationTip] = [
        RelaxationTip(imageName: "Meditate", tip: "Meditate with your human pet"),
        RelaxationTip(imageName: "Juggle", tip: "Juggle for a while"),
        RelaxationTip(imageName: "DreamOfMice", tip: "Dream of mice"),
        RelaxationTip(imageName: "Origami", tip: "Make some Origami"),
        RelaxationTip(imageName: "MakeDogJuggle", tip: "Get the dog juggling"),
    ]
}

// Adding a Picker 
struct PickerViewExample: View {
    // reference to array of instances
    let tips = RelaxationTip.demoTips 
    // holds the selected value index
    @State private var selectedPickerIndex = 0
    
    var body: some View {
        VStack {
            Picker(selection: $selectedPickerIndex, label: Text("Pick your mood")) {
                ForEach(0 ..< tips.count) { index in
                    HStack {
                        Image(self.tips[index].imageName)
                            .resizable()
                            .scaledToFit()

                        Text(self.tips[index].tip)
                    }
                }
            }
            Text("You've selected \(self.tips[self.selectedPickerIndex].tip)")
        }
    }
}
