[SOLVED] SwiftUI Image is not showing up in Swift Playground on macOS using Xcode 15

SwiftUI Image is not showing up in Swift Playground on macOS using Xcode 15

I have a Swift Playground in Xcode 15 that has a file structure as follows:

|-.swiftpm/
|----Resources/
|    |----cat.png
|    |----plane.png
|    |----train.png
|----MyApp.swift
|----ExampleView.swift

In ExampleView.swift, I had Xcode (using "+" button) to help me insert the Image:

import SwiftUI

struct ExampleView: View {
    var body: some View {
        Image("cat.png")
    }
}

But the image would not show on preview, I also tried:

Image(uiImage: #imageLiteral(resourceName: "cat.png"))

and

Image(uiImage: UIImage(named: "cat.png")!)

As suggested in the answer of How can I use image inside Xcode 11 playground? and How do we display an image in a SwiftUI playground? However, both of them crashed during preview and removing .png extension does not work either.
What can I do next?

Solution

It turns out that when I was adding the image file, I added it under the folder "Resources" and didn't work. Added it to the root folder for the second try, Xcode created Assets.xcassets in the project, and it worked.
