XCode 16 throws error message ion Defaults code #190
Description
Since updating to XCode 16, the following error is thrown in the Defaults package: "Accessing StateObject's object without being installed on a View. This will create a new instance each time."
I'm using the package in one view only:
public let extensionDefaults = UserDefaults(suiteName: "...")!
extension Defaults.Keys {
public static let isBypass = Key<Bool>("isBypass", default: false, suite: extensionDefaults)
public static let deviceID = Key<String>("deviceID", default: noneDeviceID, suite: extensionDefaults)
}
struct TabSettingsView: View {
...
@Default(.deviceID) var deviceID: String
@Default(.isBypass) var isBypass: Bool
...
}Am I using it wrong? Before, in XCode 15, this error did not show up. And I'm using the latest main branch commit.

It's either either a false-positive warning or a bug in SwiftUI. Let's see if Xcode 16.1 fixes it.

Same issue here in 16.1, any time I even access a Defaults value.

I tried with 8.2.1 and same issue as 9.0.0, when I rollback to 7.1.0 it gone

Can confirm that 8.0.0 is the culprit. It's not an issue in 7.3.1 but it is in 8.0.0.

I have a potential fix if anyone would be willing to give it a try: #222
