The @ObservedResults property wrapper used in the examples on this page is intended for use in a SwiftUI View. If you want to observe results in a view model instead, register a change listener.
New in version 10.19.0.
The Realm Swift SDK allows you to extend .searchable . When you use ObservedResults to query a realm, you can specify collection and keypath in the result set to mark it as searchable.
The collection is the bound collection represented by your ObservedResults query. In this example, it is the dogs variable that represents the collection of all Dog objects in the realm.
The keypath is the object property that you want to search. In this example, we search the dogs collection by dog name. The Realm Swift .searchable implementation only supports keypaths with String types.
struct SearchableDogsView: View { @ObservedResults(Dog.self) var dogs @State private var searchFilter = "" var body: some View { NavigationView { List { ForEach(dogs) { dog in DogRow(dog: dog) } } .searchable(text: $searchFilter, collection: $dogs, keyPath: \.name) { ForEach(dogs) { dogsFiltered in Text(dogsFiltered.name).searchCompletion(dogsFiltered.name) } } } }}The @ObservedResults property wrapper opens a realm and returns all objects of the specified type. However, you can filter or query @ObservedResults to use only a subset of the objects in your view.
To filter @ObservedResults using the NSPredicate Query API, pass an NSPredicate as an argument to filter:
struct FilterDogsViewNSPredicate: View { @ObservedResults(Dog.self, filter: NSPredicate(format: "weight > 40")) var dogs var body: some View { NavigationView { List { ForEach(dogs) { dog in DogRow(dog: dog) } } } }}New in version 10.24.0: Use where to perform type-safe queries on ObservedResults.
To use @ObservedResults with the Realm Type-Safe Query API, pass a query in a closure as an argument to where:
struct FilterDogsViewTypeSafeQuery: View { @ObservedResults(Dog.self, where: ( { $0.weight > 40 } )) var dogs var body: some View { NavigationView { List { ForEach(dogs) { dog in DogRow(dog: dog) } } } }}New in version 10.29.0.
The @ObservedSectionedResults property wrapper opens a realm and returns all objects of the specified type, divided into sections by the specified key path. Similar to @ObservedResults above, you can filter or query @ObservedSectionedResults to use only a subset of the objects in your view:
@ObservedSectionedResults(Dog.self, sectionKeyPath: \.firstLetter, where: ( { $0.weight > 40 } )) var dogsRetroSearch is an open source project built by @garambo | Open a GitHub Issue
