Dangerfile cannot be compiled when using Xcode 16

[AndrewVebster]

Hi 👋

When running danger-swift on a device with Xcode 16 the command fails with this error:

  7 | let danger = Danger()
    |              `- error: cannot call value of non-function type 'module<Danger>'

Running locally and on Bitrise - the error is the same. Using this command: swift run danger-swift local --cwd ../../ or this on CI swift run danger-swift ci --no-publish-check -f --cwd ../../

I believe my setup is pretty standard:

• Danger installed via SPM without any additional plugins
• Simple Dangerfile - I removed everything a left only this 👇

  
  import Danger
  import Foundation

let danger = Danger()

⚠️  **The same setup works fine with Xcode 15.**

### Environment
- Xcode 16.0 beta 4 (16A5211f)
- Running locally on macOS 15.0 Beta (24A5298h)
- or running on Bitrise CI, the error is the same

### Other Info

My assumption is that `import Danger` doesn't work as expected. Because compiler doesn't see other types and functions. For example, `fail` function:

19 | fail(message: "Message", file: $0, line: 2) | `- error: cannot find 'fail' in scope

Or `DangerDSL`.

I tried installing danger-swift from `brew` instead of SMP when running on CI but the result is the same.

I could reproduce the problem with Xcode 16 beta 6 (16A5230g). Do we have any updates about this issue or a possible workaround? Thank you!

I just ran into this issue with Xcode 16.0 RC 1 (16A242). Is there any update on this?

[oronbz]

Same here with RC

let danger = Danger()
    |              `- error: cannot call value of non-function type 'module<Danger>'

Is it possible that it thinks you are referring to the Danger module and not the Danger function? Would Danger.Danger() work?

[marcomasser]

Unfortunately, this doesn’t solve the issue:
