R.swift 7 – Major version, Xcode plugin, internal refactor

[tomlokhorst]

⚠️ This is a test version of a new version major of R.swift.

Global overview:

• Refactored internals (therefore: breaking changes)
• Merged R.swift and R.swift.Library projects
• Smaller generated code
• A lot of fixes to open issues
• SPM Plugin support

This version still needs testing in real world projects, to see if there are things broken that shouldn't be. Also a proper migration guide needs to be written.

---

If you want to help testing this version in your project:

CocoaPods:
pod 'R.swift', '~> 7.0.0-alpha.17'
SPM:
.package(url: "https://github.com/mac-cain13/R.swift.git", branch: "refactor")

Hello, is there any way how to prevent package from rerunning the plugin for generating resources on every build eventough no changes were made? It takes too much time when I'm creating and testing UI in SwiftUI previews.

[tomlokhorst]

I don’t know.

In particular, I’m not sure what the slow part is here. We’ll have to investigate what’s causing the slowness. Is calling any build tool slow (even if it does nothing)? Or is Rswift slow, because it does a lot of redundant work? That might be optimized by generating an “input file”, but maybe then the generation of the input file becomes the slow part…

So in conclusion: I’ll have to investigate this future 🙂
