Bookmark di ArticleListView

[dekapd99]

Aplikasi tetap berjalan cuma gak menampilkan berita apapun karena ada masalah di image icon bookmark

Penyebab error:

1. Thread 1: Fatal error: No ObservableObject of type ArticleBookmarkViewModel found. A View.environmentObject(_:) for ArticleBookmarkViewModel may be missing as an ancestor of this view.
2. No ObservableObject of type ArticleBookmarkViewModel found. A View.environmentObject(_:) for ArticleBookmarkViewModel may be missing as an ancestor of this view.

CrashReportError: Preview is missing environment object "ArticleBookmarkViewModel"

iNews crashed due to missing environment of type: ArticleBookmarkViewModel. To resolve this add .environmentObject(ArticleBookmarkViewModel(...)) to the appropriate preview.

// Bookmark button Button { toggleBookmark(for: article) } label: { // jika ada Artikel yang di Bookmark maka munculkan icon Bookmark Fil, jika tidak ada maka pakai icon bookmark biasa Image(systemName: articleBookmarkVM.isBookmarked(for: article) ? "bookmark.fill" : "bookmark") }

Penyebab: kesalahan pemanggilan environment object di root project file iNews.swift, dan di Views files folder ArticleRowView.swift, ArticleListView.swift, dan NewsTabView.swift

Dari code ini di iNews.swift:
@StateObject var articleBookmarkVM = ArticleNewsViewModel()
menjadi
@StateObject var articleBookmarkVM = ArticleBookmarkViewModel()

Dari code ini di ArticleRowView.swift, ArticleListView.swift, dan NewsTabView.swift:
@StateObject static var articleBookmarkVM = ArticleNewsViewModel()
menjadi
@StateObject static var articleBookmarkVM = ArticleBookmarkViewModel()

Hasilnya: Preview Canvas bisa dilakukan dan tidak ada error ketika build & run di ios emulator
Notes: HARUS HATI-HATI KETIKA MEMANGGIL ENVIRONMENT OBJECT
