Accessing MainActor isolated properties, from nonisolated View function (PhotosPicker)

Using Swift
5

Thanks for the feedback, you were right the error was misleading, i have found the actual culprit of the problem:

It's the PhotosPicker, updating the same example, this is reproducible.

struct FooView: View {
    
    @MainActor @State var bar: Bool = false
    
    var body: some View {
        
        PhotosPicker(selection: .constant(nil),
                     photoLibrary: .shared()) // PICKER CLOSURE
        {
            if bar { // 1. WARNING
                ProgressView()
                    .progressViewStyle(.circular) // 2. WARNING
            }
        }
    }
}

The warning has also changed to

Main actor-isolated property 'bar' can not be referenced from a Sendable closure

The init of PhotoLibrary, in the standard PhotosUI module has the following initializer:

@MainActor @preconcurrency public struct PhotosPicker<Label> : View where Label : View {
    @preconcurrency nonisolated public init(selection: Binding<PhotosPickerItem?>,
                                            matching filter: PHPickerFilter? = nil,
                                            preferredItemEncoding: PhotosPickerItem.EncodingDisambiguationPolicy = .automatic,
                                            photoLibrary: PHPhotoLibrary, @ViewBuilder
                                            label: @Sendable () -> Label) // THE TRIGGERING CLOSURE
}

I still don't know how to fix it tho.
