My pragmatic take on infinite scrolling/lazy loading in the SwiftUI. Given example performs `fetchNextPageIfPossible` when the row that appeared is related to the one of the last 10 of models (Identifiable-s).

Example.swift

ForEach(viewModel.repos) { repo in
    RepositoryRow(repo: repo)
        .onAppear(
            ofViewRelatedTo: repo,
            from: viewModel.repos,
            inSuffixOfLength: 10,
            perform: viewModel.fetchNextPageIfPossible
        )
}

View+OnAppear.swift

extension View {
    func onAppear<Id, Ids>(
        ofViewRelatedTo identifier: Id,
        from identifiers: Ids,
        inSuffixOfLength suffixLength: Int,
        perform: @escaping () -> Void
    ) -> some View
    where Id: Identifiable,
          Ids: Sequence,
          Ids.Element == Id
    {
        return onAppear {
            if identifiers
                .suffix(suffixLength)
                .contains(where: { $0.id == identifier.id })
            {
                perform()
            }
        }
    }
}
