Moya: Building Moya using Carthage

[mobilestar0223]

I have encountered below error when I updated Moya in Carthage.
I have found same issues and tried all suggestion. These didn't work for me.
Please help me!

The following build commands failed:
    CompileSwift normal arm64 /Volumes/Data/MyProject/Carthage/Checkouts/Moya/Source/Error.swift
    CompileSwift normal arm64 /Volumes/Data/MyProject/Carthage/Checkouts/Moya/Source/RxSwift/Moya+RxSwift.swift

Carthage Version: 0.18.1
xcrun swift -version: Apple Swift version 3.0.1 (swiftlang-800.0.58.6 clang-800.0.42.1)
Xcode: Xcode 8.1 8B62

I also have an issue when resolving Moya dependencies in the following line
RxCococa*** Building scheme "RxCocoa-iOS" in Rx.xcworkspace

after I tried to rebuild the frameworks with carthage update --platform iOS --no-use-binaries (for the new Swift 3.0.1). Should this be posted in RxSwift or might this be resolved by updating the Cartfile in Moya?
The specific error in xcodebuilt output is duplicate symbol __TMRbBp in ...KVOObservable.o and ...UIButton+Rx.o which might be related to this issue

I've got the same error of "RxCocoa Building error".

[AndrewSB]

Does it only come up when building RxCocoa through Moya? Not if you just have a Cartfile with github "ReactiveX/RxSwift" ~> 3.0?

If the issue is in fact with RxSwift, then it should be tracked on their library, on the issue @fruitcoder mentioned https://github.com/ReactiveX/RxSwift/issues/970.

[mobilestar0223]

Hello, Andrew.
Thanks for your advice.
But it doesn't work for me also. I updated RxSwift from master repo again and also update Moya.
But same error occurred.
I don't know this is because RxSwift or Moya.
Thanks.

@AndrewSB I just tested a new project which has a Cartfile with only github "ReactiveX/RxSwift" ~> 3.0. Everything works fine. And I tested a new project with only github "Moya/Moya" "8.0.0-beta.2". I got this error:

[AndrewSB]

Can you delete your derived data and try again?

[Tynox]

Cleared derived data. Still got this error.

[AndrewSB]

Hmm, so it's working on me when I check specify github "Moya/Moya" "master". Testing now with the 8.0.0-beta.2 release.

I have deleted whole derived data.
Also checkout Moya from master.
Still get same error.

[AndrewSB]

Hmm, I'm definitely seeing the issue on the latest release, but not on master. It seems to come and go.

@mobilestar0223 after it fails, can you open the Rx.xcodeproj inside Carthage/Checkouts/RxSwift and see if you can build the RxCocoa target from Xcode? If not, can you paste your error?
Trying to get a handle on what the issue is.

We may just want to do a new release soon -- not sure if that will fix the problem though, let's investigate it

[AndrewSB]

I think I've got a handle on the issue - I'm only seeing the Ld error from RxCocoa if I'm trying to build version 3.0.0-beta.1, if I checkout RxSwift at 3.0.1 instead, I don't get the build failure

So we should release master as a new version ASAP, since our latest release (https://github.com/Moya/Moya/releases/tag/8.0.0-beta.3) points to RxSwift 3.0.0-beta.1.

@ashfurrow can we do a new release? The Cartfile on master points to a non-breaking install of RxSwift 😄

[ashfurrow]

Aye, I'll do a release asap. Thanks for looking into this!

[ashfurrow]

All done 👍 Released as 8.0.0-beta.4, let us know if this works. I've opened https://github.com/Moya/Moya/issues/759 to decide if we want to release that as a 8.0.0 final.

[AndrewSB]

Thanks @ashfurrow!

Fix for this issue: target Moya 8.0.0-beta.4.

If anyone is having issues, please reopen this. Im happy to help!
