XCode 12:“SessionDelegate"在不同模块中有不同的定义 [英] XCode 12: 'SessionDelegate' has different definitions in different modules
问题描述
此问题发生在 XCode 12 Beta5 之后.Xcode 不允许不同的模块定义相同的名称(可能用于公共类和协议).Alamofire 和 Kingfisher 似乎同时定义了 SessionDelegate.我仍在努力寻找解决方案..
This problem occurs after XCode 12 Beta5. Xcode doesn't allow different modules to define same names (Probably for public classes & protocols). Alamofire and Kingfisher appears to define SessionDelegate at the same time. I'm still trying to find a solution..
我正在我们的应用程序中实现 iOS 14 小部件.我已经开始使用 XCode 12 Beta 2 并且一切都编译得很好.当我将 XCode 更新到 XCode 12 Beta 6 时，我遇到了以下错误:
I'm implementing iOS 14 Widgets in our application. I have started working with XCode 12 Beta 2 and everthing was compiling fine. When I have updated XCode to XCode 12 Beta 6, I faced with following error:
'SessionDelegate'在不同的模块中有不同的定义；第一个区别是模块Kingfisher.Swift"中的定义找到了结尾班级
'SessionDelegate' has different definitions in different modules; first difference is definition in module 'Kingfisher.Swift' found end of class
我还附上了错误文件的屏幕截图.
I'm also attaching the screenshot of the file with error.
有什么方法可以编辑头文件，为 Alamofire 或 Kingfisher 的 SessionDelegate 使用不同的名称?是否有解决此问题的解决方法?
Is there any way to edit header files to have different names for SessionDelegate for Alamofire or Kingfisher? Is there any workaround to overcome this issue?
以下是我迄今为止尝试过的方法:
Here are things I have tried so far:
- 我已将 Alamofire 和 Kingfisher 都更新到最新版本
- 我已经清理了 Podfile.lock 和所有 Pod 以及派生数据
- 我尝试使用旧版构建系统 进行编译
- I have updated both Alamofire and Kingfisher to latest version
- I have cleaned Podfile.lock and all pods as well as Derived Data
- I tried to compile with Legacy Build System
推荐答案
此时(Xcode 12.0 或 Xcode 12.2b2)，唯一可能的解决方案是重命名 Objective-C 接口并避免冲突.这可以通过以下方式之一完成:
At this moment (Xcode 12.0 or Xcode 12.2b2), the only possible solution is to rename the Objective-C interface and avoid conflicts. This could be done by one of:
- 完全重命名冲突类，更新所有使用它的地方(例如，将 SessionDelegate 替换为 KingfisherSessionDelegate)
- 将
@objc(...)属性添加到 Swift 类，这将更新生成的...-Swift.h文件中的 Obj-C 接口并避免名称冲突.
- Rename conflicting class entirely, update all places where it's used (e.g. replace SessionDelegate by KingfisherSessionDelegate)
- Add
@objc(...)attribute to a Swift class, which will update the Obj-C interface in a generated...-Swift.hfile and avoid the names conflict.
// SessionDelegate.swift
@objc(KFSessionDelegate)
class SessionDelegate: NSObject { ... }
// Kingfisher-Swift.h
@interface KFSessionDelegate : NSObject
...
@end
此解决方案已包含在 Kingfisher 5.15.4 版本中并且可以应用于任何其他库和您自己的框架.
This solution is already included in the Kingfisher 5.15.4 release and could be applied to any other libraries and your own frameworks.
