问题标签 [xcode11.4]

我在 Xcode 11.4 中收到以下代码错误

请看附件图片

我已经将 c++ 从 Xcode 9.4 复制到 Xcode 11.4，如下图所述

仍然出现错误。请帮我。

我刚刚将我的 Xcode 从 11.3 更新到 11.4，我用 SwiftUI 编写的项目开始表现不同。我曾经为布尔值调用toggle()函数，它曾经触发didSet属性观察器，但是，它不再工作了。

假设我们有一个State名为 的属性isSettingOn。我曾经这样称呼它：

isSettingOn.toggle()

这触发didSet了财产的观察者。现在，只有当我这样称呼时：

isSettingOn = true

这是工作。

我的项目都是基于这种行为，现在这种变化基本上破坏了一切。有谁知道我在这里是否真的做错了什么？

编辑：

添加了演示代码：

Xcode 11.4 发行说明介绍了Xcode 11.4现在有新选项可以选择Terminal而不是Xcode 的 Console。但是，我无法在Xcode -> Scheme Editor 的 Options 选项卡中找到终端选项

它实际上是否像 VSCode（在调试区域中）一样可用？如果是这样，如何启用此选项？

对不起，我已经从一个 zip 文件而不是从应用商店安装了 Xcode 11.3，现在 Xcode 11.4 就在这里，我需要它与 ios 13.4 一起工作，所以如何在不从苹果下载再次下载整个 Xcode 的情况下更新它？.. .

我是新手，PromiseKit但是我无法获得一些非常基本的工作。考虑一下：

以下给了我每一行的错误：

无法将类型的值转换Promise<Bool>为闭包结果类型 Guarantee<()>

我究竟做错了什么？我一直在尝试各种组合，但似乎没有任何效果。我在PromiseKit 6.13。

发生这种情况时，我一直在尝试将一个元素插入到我的新视图控制器中：

对于那些没有加载图像的人，它说无法插入新的操作连接：找不到名为 ProfileViewController 的类的任何信息。ProfileViewController 是 ViewController 的名称。这是我的 ViewController 代码：

这是一个带有 Firebase 和 Cocoapods 的可可触摸类。这是 main.storyboard：

我正在 Xcode 中开发几个不同的应用程序，并且我使用 Swift 包作为我的“通用”库。在每个项目中，我通过转到项目的“Swift Packages”（“Info”和“Build Settings”旁边）并输入本地“file:///...”url 来添加通用 Swift 包。这检查了一个只读版本。一切都运行良好，但如果我对常用文件进行大量编辑，就会很烦人。我必须：

• 切换到另一个 Xcode 窗口，其中 Swift 包以读写模式打开。
• 编辑文件，将它们提交到 git，标记提交
• 回到应用程序项目，菜单栏 > 文件 > Swift 包 > 重置包缓存（假设我移动了标签，而不是创建一个新标签）

有没有办法简化这个，所以我可以编辑和编译 Swift 包中的文件，而不必每次都执行 git 步骤？

在我将 MBP 更新为 10.15.4 和 Xcode 11.4.1 后，构建错误消失了。还是不知道。

我的项目在 Xcode 11.3.1 中运行良好。当我将 Xcode 更新到 11.4 时，构建时出现此错误。

我删除了派生数据并重建，错误仍然存​​在。

我不知道哪里错了，有人可以给我一些建议吗？

以下是关于我的项目的一些信息：

• 同时使用 Objective-C 和 Swift

• 使用 Cocoapods (v1.9.1)

我正在尝试使用新的 Xcode 11.4 功能在 ios 模拟器中测试推送通知。

我的应用同时具有 NotificationService 和 NotificationContent 扩展，可以在向用户显示之前更改消息。

要向模拟器发送通知，我正在使用终端命令：

我的 push.apns 是这样的：

我在屏幕上看到了通知，但似乎“链接”属性不起作用。当我点击推送时，在这种情况下，我希望看到第三个订单的屏幕，但我看到的是应用程序的主屏幕。

如有任何帮助，我将不胜感激。谢谢。

目前我在macOS High Sierra 10.13.6上使用Xcode 10.1，在 2011 年初配备 4GB RAM 的 MacBook Pro 上。

问题是我无法升级到 macOS Catalina。是否可以在 macOS High Sierra 中安装 Xcode 11.3？或者是否有任何其他安全解决方案可以在我不受支持的 2011 年初 MacBook Pro 中安装 macOS Catalina，然后安装 Xcode 11.3？

请建议一个经过良好测试且安全的解决方案。
