Jetpack Compose から SwiftUI に来ましたが今の謎をどうにかしたい 😩 👉 https://android.benigumo.com/20231221/swiftui-property-wrapper/

BirdsSearchResult_.swift

import SwiftUI
import SwiftData
import BackyardBirdsData

struct BirdsSearchResults<Content: View>: View {
  @Binding var searchText: String
  var content: (Bird) -> Content

  @Query(sort: \Bird.creationDate) private var birds: [Bird]

  var body: some View {
    let filtered = searchText.isEmpty ? birds : birds.filter { bird in
      bird.speciesName.contains(searchText)
    }
    ForEach(filtered) { bird in
      content(bird)
    }
  }
}
