A new property wrapper for SwiftUI ObservableObject.

What's New

SwiftUI SharedObject 2.0.0


SwiftUI SharedObject 🍱

@SharedObject is an alternative to @StateObject, @ObservedObject, @EnvironmentObject to handle ObservableObject. If you need to have multiple objects of the same class persisted among multiple view instances, its difficult to handle the situation with other wrappers: with @StateObject the object will deinit with the view and be generated only for the specific view instance, with @EnvironmentObject you can bind only one instance of the same class for each Environment and with @ObservedObject is difficult to propagate object in nested views.

@SharedObject simply stores the objects using an identifier, so you can retrieve it each time you'll need it.


Retrieve the shared object with the given id or, if not present, create a shared object with an initial value:

@SharedObject("A") var letterA = Letter()

If you are sure that the object is already been created you can just retrieve the shared object:

@SharedObject("A") var letterA: Letter

You can give a default initial value to the class, so you don't need to specify in each view you think the object will be created:

final class Letter: SharableObject {

  var value: String
  init(_ value: String) {
	self.value = value
  static var initialValue: Self {
