如何检查documents目录下是否存在多个文件？(Swift)

guard let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first else {
    print("无法获取documents目录路径")
    return
}

do {
    let fileURLs = try FileManager.default.contentsOfDirectory(at: documentsDirectory, includingPropertiesForKeys: nil, options: [])
    let fileCount = fileURLs.count
    if fileCount > 1 {
        print("documents目录下存在多个文件")
    } else if fileCount == 1 {
        print("documents目录下只存在一个文件")
    } else {
        print("documents目录下没有文件")
    }
} catch {
    print("无法获取documents目录下的文件")
}
