SOLVED: Easiest way to share data between app and widget?

Forums > SwiftUI

	@ejeklint Jul '20 I'm dipping my toes into the cold stream of widgetkit and feel a bit lost. What would be the easiest way to share data from the app (which displays a list of prices for precious metals, updated now and then) to a widget showing only one value? First I tought of @EnvironmentObject, but that won't work since the widget is a different target (right?). Any hints on how I should approach this? 3
	@nemecek-filip Jul '20 Sharing between main app and other targets is usually done with AppGroup which are capability you can turn on for your project. You then define app group name and this can be used to create special shared `UserDefaults`. So instead of `standard` one you use the initilizer `UserDefaults(suiteName: )` where "suiteName" is the name of the app group. This way you can easily share data. 3
	@stammy Sep '20 I understand the App Group + AppStorage w/ suiteName stuff but how can you get the Widget to trigger code that lives in the main app that will do user auth, fetch data and all the related logic I need before it ends up getting stored in the shared app group userdefaults? I've read about breaking out some code into a shared framework that is imported into both the main app and the widget but I've been having issues with that as well. 3
	@Lamin HWS+ Oct '20 how can `@AppStorage` be used with a dictionary? i keep on getting No exact matches in call to initializer error 3
	@theswifthacker22 Feb '21 This article gives a good walkthrough of sharing data with a widget: https://medium.com/better-programming/sharing-object-data-between-an-ios-app-and-its-widget-a0a1af499c31 3
