Full disclaimer: I haven’t looked into this bug, so I’m just going to describe 
higher-level workflow tips.

The way to do what you’re asking for is to build a toolchain, which is far too 
time-consuming for the debugging workflow you want here.  This diagnostic is 
coming from somewhere in Semantic Analysis, so you just need to take your 
minimally-reproducing test case and only run the compiler up to that point.  To 
do this in Xcode, since you already have the project in hand, you can do the 
following:

- Select the ‘swift’ scheme
- Pull up the scheme editor (⌘+⇧+<)
- Select the ‘Arguments’ tab and click the ‘+’
- (For this particular case) add ‘-frontend -typecheck 
/Path/To/This/Test/Case.swift’
- Close the scheme editor
- Build and run

Hey Mike, I've found this presentation by Ayanonagon to be helpful in
getting a functional development environment up and running:

https://speakerdeck.com/ayanonagon/contributing-to-swift

Also, I'm going to be facilitating a workshop at try! Swift NYC to help
people set up functional development environments in Swift. Part of this is
going to be improving the getting started instructions and getting people
started a few weeks before the conference. I'd be glad to have another set
of new eyes to review it before sending it out.

There's also a few people in #swift-compiler on the iosdevelopers slack.
It's not a deep bench in terms of compiler expertise, but I'll answer
anything I can.

Good luck!

Brian

[swift-dev] Debugging on Xcode

[Mike Choi via swift-dev]

Hello Swift community,

I’m currently trying to debug SR-5556 
https://bugs.swift.org/plugins/servlet/mobile#issue/SR-5556.
TL;Dr This bug has to do with Xcode not providing a fixit when it should.

To proceed, I built Swift and generated an Xcode project but have no idea how 
to debug the problem. Is there a way for me to input Swift code into the built 
Swift compiler via Xcode and debug in Xcode??

If not, what is the usual way to debug something like this?

Thank you for your time!

Best,
Mike JS. Choi
