Usage

For a none-trivial example take a look at the example app Books, which demostrates the usage of LoadableView using the OpenLibrary API

LoadableView is great for fetching lists of things:

import SwiftUI
import LoadableView
structBook{letname:String}structBooksView:DefaultLoadableView{@StateObjectvarvm=BooksViewModel()func loaded(_ books:[Book])->someView{List{ForEach(books){ book inText(book.name)}}}}@MainActorfinalclassBooksViewModel:LoadableViewModel{@PublishedvarviewState:ViewState<[Book]>=.notLoaded
varoverlayState:OverlayState=.none
privateletservice=BookService()func load()asyncthrows->[Book]{tryawait service.fetchAll()}}

Resources that have an ID use IDedLoadableView:

import SwiftUI
import LoadableView
structBookView:IDedDefaultLoadableView{varid:UUID@StateObjectvarvm=BookViewModel()func loaded(_ book:Book)->someView{VStack{Text(book.name)}}}@MainActorfinalclassBookViewModel:IDedLoadableViewModel{varid:UUID?@PublishedvarviewState:ViewState<Book>=.notLoaded
varoverlayState:OverlayState=.none
privateletservice=BookService()func load(id:UUID)asyncthrows->Book{tryawait service.fetchBook(withId: id)}}
