如何使用 cocoapods 避免多项目工作区中类的重复

Question

我在业余时间做一个应用，想问你一个问题，我的工作区有3个子项目：presentation、domain和data，每个都是静态框架，有自己的pods，一切都很酷，但现在我有一个问题，我不知道如何解决。我有几个 firebase 依赖项，其中一些必须在 Presentation 中，其他必须在 Data 中，执行时会出现问题，因为它给我一个错误：

Class PodsDummy_FirebaseUI is implemented in both /Users/.../Debug-iphonesimulator/PresentationCleanExample.framework/PresentationCleanExample (0x104ffada0) and /Users/.../data/Containers/Bundle/Application/A15FF8B8-7B67-4512-8DFD-04F008175660/CleanExample.app/CleanExample (0x100c6e288). One of the two will be used. Which one is undefined.

所以我在 FirebaseUI/Storage 的 podspec 中看到的是以下内容： https://github.com/firebase/FirebaseUI-iOS/blob/master/FirebaseStorageUI.podspec

s.dependency 'Firebase/Storage'
s.dependency 'GTMSessionFetcher/Core', '~> 1.5.0'
s.dependency 'SDWebImage', '~> 5.6'

这让我觉得 cocoapods 没有正确解决依赖关系 Firebase/Storage。

问题是，这只是我从 Firebase 获得的数千个重复的 class 中的一个，用于遵循上图。我想有一种方法可以只注入一次 Firebase 依赖项，从而避免 class 重复，但我不知道怎么做。

我的播客文件：

platform :ios, '13.6'

workspace 'CleanExample'

def firebase_pods
  pod 'Firebase/Core', '7.11.0'
  pod 'Firebase/Auth', '7.11.0'
  pod 'Firebase/Firestore', '7.11.0'
  pod 'Firebase/Storage', '7.11.0'
  pod 'FirebaseFirestoreSwift', '7.11.0-beta'

    end

问题

是不是FirebaseStorageUI.podspec文件有问题或者是可可的限制pods?
我的 Podfile 是不是错了？

最后我解决了这个问题 post https://medium.com/@GalvinLi/tinysolution-fix-cocoapods-duplicate-implement-warning-5a2e1a505ea8 因为它让我理解了问题。

如果我没理解错的话OTHER_LDFLAGS 正在重复添加框架。

然后为了避免原始消息问题Class *** is implemented in both我在目标'CleanExample'中安装所有pods并从以下文件中删除OTHER_LDFLAGS行。

Pods-DataCleanExample.debug.xcconfig
Pods-DataCleanExample.release.xcconfig
Pods-PresentationCleanExample.debug.xcconfig
Pods-PresentationCleanExample.release.xcconfig
