Seems like they released gRPC-Swift 0.9.0 with "fixes for Swift 5".

@douglaswsilva: would you mind trying gRPC-Swift 0.9.0? Should be a matter of editing the SDK Cartfile and running Carthage again.

@JonasVautherin I've just checked and I see that gRPC-Swift 0.9.0 doesn't work with the XCode 10.1 (Swift 4.2) but the latest commit in master works.

[JonasVautherin]

Oh, good find!

Just to recap then: it broke, but...

• We haven't changed the release of gRPC-Swift that we use
• We are still building with Swift 4.2

What could have changed that would break the build? Could it be a change in RxSwift? Like instead of ~> 4.0 should we fix it to some version?

Hi @JonasVautherin,

• I think that the Carthage was broken for a while when you have changed the version of gRPC-Swift that you use. I think it was the only issue for the Carthage builds. Please check my PR Point to the working commit of gRPC-Swift to fix Cartgage builds #122 that should fix Carthage support for the SDK.
• Yes, we're still using XCode 10.1 and Swift 4.2. We can't migrate our code to Swift 5 and XCode 10.2 yet as some of our 3rd party libraries haven't done the migration.
