SkeletonUI's offers a couple of wrappers for List and ForEach, which try to behave the same way. Those are SkeletonList and SkeletonForEach. If you take a look to the code:

public struct SkeletonForEach<Data, Content>: View where Data: RandomAccessCollection, Data.Element: Identifiable, Content: View {
    private let data: Data
    private let quantity: Int
    private let content: (Bool, Data.Element?) -> Content

    public init(with data: Data, quantity: Int = 1, @ViewBuilder content: @escaping (Bool, Data.Element?) -> Content) {
        self.data = data
        self.quantity = quantity
        self.content = content
    }

    public var body: some View {
        ForEach(0 ..< (data.isEmpty ? quantity : data.count), id: \.self) { index in
            self.content(self.data.isEmpty, self.data.isEmpty ? nil : self.data.map { $0 }[index])
        }
    }
}

Both gives you access to the Data.Element on the specified index. If you need to only access the index, you can either ask for array.indexOf(element) or better, create your own wrapper.

PD: Please, try to fill your next issue following the provided template.
