在框架模块中引入非模块化头文件

如何解决在框架模块中引入非模块化头文件

我正在尝试使用 Flutter 在 iOS 上构建应用程序。该应用程序在 Android 上构建和运行良好，但该应用程序拒绝在 iOS 上构建。要构建应用程序，我使用命令 Flutter build ios

This is the error I receive when trying to build：

Xcode's output:

Encountered error while building for device.

据我所知，主要问题来自错误：

include of non-modular header inside framework module

我尝试按照 this solution 中的建议将 Allow Non-Modular Includes In Framework Modules 变成 YES，但这并没有改变任何东西。 This thread 提供了一个解决方案，涉及到框架 -> 目标 -> 构建阶段 -> 标题。但是我的项目没有这样的位置。

我对使用 Xcode 和构建 iOS 应用程序非常陌生，因此我们将不胜感激。

编辑：经过更多研究，我看到通过在导入结束时将替换为 "" 解决了一些类似的错误，这样导入看起来像这样：

#import "FBSDKCoreKit/FBSDKAccesstoken.h"

这并没有消除错误，但我想我应该把它包括在这里，以防有人推荐这个解决方案。

解决方法

你走在正确的轨道上。 “非模块化”标头基本上是一个私有标头。错误是抱怨这样的标头是由公共标头导入（可能是递归的），实质上是将私有标头设为公开。这通常是意外或软件设计不良的迹象，因此最近的 Xcode 版本已将其转化为错误。

由于您在 3rd 方库中收到此错误，您的选择是

获取该库的更新版本以修复错误
降级到不将其视为错误的旧版本 Xcode (Xcode 11.7)
找到一种方法来禁用 Xcode 中的错误。如果您可以以某种方式访问 Facebook SDK 的构建设置，则需要在其中设置“允许非模块化包含在框架模块中”，而不是在您的应用设置中
