visionOS 1.0中PhotosPicker嵌入popover无法显示问题咨询

环境：visionOS 1.0、Xcode 15.2

在visionOS开发场景下，将PhotosPicker嵌入popover组件时无法触发照片选择界面，但替换为sheet组件后功能完全正常。

失效的popover实现代码 #

struct PhotoPickerTest: View {
    @State private var selectedPhotoItem: PhotosPickerItem?
    @State private var isTaped: Bool = false
    
    var body: some View {
        Button("", systemImage: "plus") {
            isTaped = true
        }
        .popover(isPresented: $isTaped) {
            PhotoPickerView()
        }
    }
    
    func PhotoPickerView() -> some View {
        PhotosPicker(selection: $selectedPhotoItem) {
            Image(systemName: "photo")
        }
    }
}

正常工作的sheet实现代码 #

struct PhotoPickerTest: View {
    @State private var selectedPhotoItem: PhotosPickerItem?
    @State private var isTaped: Bool = false
    
    var body: some View {
        Button("", systemImage: "plus") {
            isTaped = true
        }
        .sheet(isPresented: $isTaped) {
            PhotoPickerView()
        }
    }
    
    func PhotoPickerView() -> some View {
        PhotosPicker(selection: $selectedPhotoItem) {
            Image(systemName: "photo")
        }
    }
}

结论 #

这是visionOS 1.0的框架兼容性Bug，并非操作错误。PhotosPicker与popover的模态层级存在冲突，导致无法正常唤起照片选择界面；而sheet的模态呈现机制与PhotosPicker适配性良好，因此可以正常工作。
