XCode 16 throws error message ion Defaults code

[sarensw]

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.

Still this is an issue still even in 9.0.3, any way we can help? @sindresorhus

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