Which Xcode version are you using? The Carthage project only works with Xcode 10, not 11.

@MrMage Xcode 11.1, it is interesting, as it is working with 0.9.1/Xcode 11.1

[MrMage]

Weird, there were reports stating the opposite: #609

Is it possible that you had used 0.9.1 with old binaries built with Xcode 10?

[nakkht]

@MrMage don't think so. While using XCode 10/macOS Mojave, I was doing manual integration. When upgraded to XCode 11/macOS Catalina, I tried Carthage and it worked so continued to use it. Furthermore, circleci was setup (last week) using 11.1.0 image and using Carthage to build grpc-swift and it worked out of the box.

[MrMage]

Sorry about that, then. Weird that other users had already reported Carthage problems with 0.9.1 and Xcode 11, though. In any case, Carthage has been a constant source of pain.

If you want, you could try if it works better with #616, or revert to 0.9.1.

Here are some commits I've tried running against:
It involves running (both using Cartfile from external project and then running carthage bootstrap --platform iOS and also building by just opening SwiftGRPC-Carthage.xcodeproj from grpc-swift clone project)

Can anyone confirm that building SwiftGRPC-Carthage.xcodeproj from 44f194e does not yield the following error:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

@MrMage Since commit is not available on the remote, I've tried replacing SwiftGRPC-Carthage.xcodeproj/project.pbxproj contents, however, it did not help.

[MrMage]

Hmm, maybe the upgrade to gRPC-Core 1.23 has broken our Carthage support again. @JonasVautherin @WilliamIzzo83 @byuarus @KyoheiG3 do any of you have time to take a look?

[nakkht]

What OS version are you guys running? Did anyone try running on macOS Catalina?
I tried building 0.9.1 using carthage on 2 different machines (both using macOS Catalina/Xcode 11.1) and it built both times. My colleague is still using macOS Mojave/XCode 11.1 and carthage build failed for him. (Used same command carthage bootstrap --platform iOS
Would be glad to hear if anyone could replicate that.

[kosukeohmura]

@nakkht I tried to build 0.9.1 on macOS Catalina (10.15.1) and Xcode 11.2.1 (11B500) with Carthage (0.34.0) but it failed for me.

the command is: carthage update --platform iOS
the error is:

I also tried 0.10.0 and https://github.com/MrMage/grpc-swift/tree/rebuild-carthage-3 (source branch of #616 ) but all failed too. the error is almost same.

• Does anyone know how to build successfully v0.x with Carthage?
• Is it not of grpc-swift but swift-protobuf issue? The error says some of files of swift-protobuf are missing.

It seems like the Carthage build almost never works with Xcode 11. We strongly recommend using SwiftPM or CocoaPods instead.

[kosukeohmura]

@MrMage Okay, I will try with SwiftPM. Thanks.

[WilliamIzzo83]

@kosukeohmura I have a fork here at version 0.9.something which I'm using with Carthage.

Anyway like @MrMage says, if you can switch to swiftPM and forget about Carthage I think it's for the better. I'm still using this fork because I have some deadlines and I can't afford the switch over.

Is it not of grpc-swift but swift-protobuf issue? The error says some of files of swift-protobuf are missing.

@kosukeohmura you are probably right. If you're still interested in trying to fix this issue, try explicitly adding SwiftProtobuf in Cartfile without grpc-swift and then run carthage bootstrap --platform iOS. Once SwiftProtobuf dependency is fetched and built, roll back Cartfile to use just grpc-swift and run carthage bootstrap --platform iOS again.
P.S. it might be enough just to keep SwiftProtobuf next to grpc-swift in Cartfile

[kosukeohmura]

@WilliamIzzo83 and @nakkht Thank you for your reply. I am going to use the nio branch with SwiftPM.
