包管理器及编译速度

项目里用到了两包管理器，Cocoapods 和 Carthage 都用到了，感觉有点混乱，问了下说是优化编译速度所采取的措施，那为什么不都用 Carthage 或者 Cocoapods 有没有好的处理方式或者其他更好的方法？

名词

静态库 Static Libraries - .a。As the name says, they are static. So they are already compiled, when you import them to your project. You can share them with others without showing them your code. Note that Static Libraries currently don’t support Swift. You will have to use Objective-C within the library. The app itself can still be written in Swift.
动态库 — .dylib
framework。They are always open-source and will be built just like your app. (So Xcode will sometimes compile it, when you run your app and always after you cleaned the project.) Frameworks only support iOS 8 and newer, but you can use Swift and Objective-C in the framework.
xcframework
预编译 pre-compile

包管理器

Cocoapods

use_frameworks!tells CocoaPods that you want to use Frameworks instead of Static Libraries. Since Swift does not support Static Libraries you have to use frameworks.

插件
cocoapods-binary已经不更新了，试了下没成功，但是大体知道原因，应该是三方库本身不支持framework导致找不到header？
Rome已经不更新了，从这里找到了下面这个；
cocoapods-binary-cache可以使用，第一次完成后build time减少50%。

cocoapods-binary

# 如果想重新生成 binary，执行下面两句
rm -rf Pods _Prebuild _Prebuild_delta
pod binary prebuild master --no-fetch --push

Swift package manager

// Xcode 13 "Missing package product" using local Swift Packages
In my case on Xcode 13.1, this issue get fixed after applying File -> Packages -> Reset Package Caches enjoy!
