原因

解决方式

        什么是堆和栈

堆（Heap）

堆是一种动态内存分配的区域，在iOS开发中，它主要用于存储那些生命周期不确定的对象。当你创建一个类的实例或者动态分配空间时，这些数据通常存储在堆中。

特点:


  动态分配：内存的分配和释放是动态的，可以在运行时进行。
  管理灵活性：适用于生命周期不确定或大小可变的数据。
  性能开销：与栈相比，堆的内存分配和管理成本较高。


在iOS中，堆的使用是...

        Stable Diffusion是2022年发布的深度学习文本到图像生成模型。它主要用于根据文本的描述生成详细图像，它也可以应用于其他任务，如内补绘制、外补绘制，以及在提示词​（英语）指导下产生图生图的翻译。详细介绍看维基百科词条Stable Diffusion。

        Copilot是由OpenAI推出的一项AI语言模型技术，它可以帮助开发人员快速编写代码。Copilot虽然支持Swift代码，但官方支持的IDE并不包含Xcode。Github上有位大佬开源了一款Xcode插件CopilotForXcode实现了在Xcode上使用Copilot。


  该项目还处于早期阶段，后续版本很可能会有比较大的改动，建议读一遍README。

        并发编程基础

并发编程是一种常见的编程方式，它允许应用程序同时处理多个任务或操作。并发编程在多核处理器和分布式系统中尤为重要，因为它可以更有效地利用资源，并提高应用程序的性能。

在并发编程中，你需要处理共享资源（如内存、文件等）以及多个线程可能同时访问这些资源所带来的竞争条件问题。为了避免这些问题，你需要使用特殊的工具和技术来确保线程安全。
