    load files error: Error Domain=NSCocoaErrorDomain Code=257 "The file “common” couldn’t be opened because you don’t have permission to view it."

    选择文件的代码

    
    Button {
                        reset()
                        isFileImporterPresented = true
                    } label: {
                        Label("Choose Folder",systemImage: "square.and.arrow.up").fileImporter(isPresented: $isFileImporterPresented, allowedContentTypes: [.directory]) { result in
                            let _ = result.map { url in
                                tryGetWorkspaceInfo(url)
                            }
                            
                            
                        }
                    }.padding(4)
    

    保存 bookmark

    
    try url.bookmarkData(options: [.withSecurityScope], includingResourceValuesForKeys: nil, relativeTo: nil)
    

    从 bookmark 获取 url

    if item.bookmark == nil{
                return
            }
            var isStale = false
            do{
                let url = try URL(resolvingBookmarkData: item.bookmark!, options: [.withSecurityScope,.withoutImplicitStartAccessing,.withoutMounting],bookmarkDataIsStale: &isStale)
                root = url
                print("标签过期",isStale)
                if(isStale){
                    return
                }
                let statStr = SVN.Util.shared.stat(url: url.path)
                stat = SVN.Stat.parse(str: statStr)
                //            print(stat?.entries[0].status)
                let _ = url.startAccessingSecurityScopedResource()
                files =  FileItem.loadFiles(url: url) ?? []
                url.stopAccessingSecurityScopedResource()
            }catch{
                
            }
    

    加载文件夹的代码

    
    public static func loadFiles(url:URL) -> [FileItem]? {
            var result:[FileItem]? = nil
            do{
                var isDir:ObjCBool = false
                
                FileManager.default.fileExists(atPath: url.path, isDirectory: &isDir)
                if(!isDir.boolValue){
                    return nil
                }
                let _ = url.startAccessingSecurityScopedResource()
                let files = try FileManager.default.contentsOfDirectory(at: url, includingPropertiesForKeys: nil,options: [])
                url.stopAccessingSecurityScopedResource()
                
                
                
                result = []
                for file in files {
                    var isCurrentDir:ObjCBool = false
                    FileManager.default.fileExists(atPath: file.path, isDirectory: &isCurrentDir)
                    let item = FileItem(url: file,isDir: isCurrentDir.boolValue)
                    //                item.children = FileItem.loadFiles(url: file)
                    result?.append(item)
                }
                
                
                //            sorted files
                
                let dirs = result!.filter({ $0.isDir }).sorted { cur, next in
                    return cur.url.lastPathComponent.localizedCaseInsensitiveCompare(next.url
                        .lastPathComponent) == .orderedAscending
                }
                let others = result!.filter({ !$0.isDir }).sorted { cur, next in
                    return cur.url.lastPathComponent.localizedCaseInsensitiveCompare(next.url
                        .lastPathComponent) == .orderedAscending
                }
                
                result = dirs + others
                
            }catch{
                print("load files error:",error)
