Rxswift: RxTest fails to build in Xcode 7.3-beta2

[koke]

Running the test suite (or using the RxTest pod) throws a couple build errors when using Xcode 7.3 beta 2

XCTest+Rx.swift:67:7: Cannot invoke 'XCTAssertEqual' with an argument list of type '([AnyEquatable>], [AnyEquatable>], file: String, line: Uint)'
XCTest+Rx.swift:95:7: Cannot invoke 'XCTAssertEqual' with an argument list of type '([AnyEquatable>>], [AnyEquatable>>], file: String, line: Uint)'

It seems the file parameter on XCTAssertEqual changed from String to StaticString in https://github.com/apple/swift/pull/888

[koke]

I got a fix in https://github.com/ReactiveX/RxSwift/commit/60b4b965092c372edce7b18ed67f863d3a7a3e8b, but that breaks the builds on Xcode 7.2. I'm not sure if there's a workaround or this will have to be a new release that supports Swift 2.2 only.

Hi @koke ,

Thnx for reporting this. I'm hoping this is just an Apple but and they will fix this soon :(.

I'm not sure it would be a good idea to pull this in immediately since it you are telling me this will break on Xcode 7.2, and this is the released version. Let's monitor this and see what will Apple do here.

If they release a version that requires StaticString, then we'll make the same breaking change.

Hi @koke and @kzaher,

How can I use 60b4b96 with Carthage? Is it in a branch? If not, could we create a branch called, for example, Xcode7.3?

[kzaher]

Hi @Bogidon ,

I've created new branch xcode/7.3 If @koke makes PR to that branch, I would be happy to merge it.

[tomburns]

@kzaher the xcode/7.3 branch gets further into the build process when using Carthage (sorry, forgot to specify this), but still fails:

/Users/.../RxSwift/RxSwift/DataStructures/Queue.swift:165:16: warning: 'anyGenerator' is deprecated: renamed to 'AnyGenerator'
/Users/.../RxSwift/RxSwift/DataStructures/InfiniteSequence.swift:26:16: warning: 'anyGenerator' is deprecated: renamed to 'AnyGenerator'
<unknown>:0: error: unable to execute command: Segmentation fault: 11
<unknown>:0: error: compile command failed due to signal (use -v to see invocation)
A shell task failed with exit code 65:
** BUILD FAILED **

[kzaher]

¯_(ツ)_/¯

I've tried to support Xcode 7.3, but since even released 7.2.1 version still has horribly buggy compiler, it's pointless at this stage.

I'm waiting until they make transition from catastrophically unstable compiler to just the usually horrible one (when they release it) :)

Try building just Debug configuration. I believe Xcode compiler just fails when it tries to optimize the code.

[Bogidon]

Interesting @kzaher. I was getting the same error as @tomburns.

Let's 🙏 they fix it before release. Should we file a rdar?

[kzaher]

@Bogidon if you guys can file a radar, that would be :+1:

[stephenvisser]

Seems like this is still an issue after today's release

[ibadcool]

XCTAssertEqual(leftEquatable, rightEquatable, file: file, line: line)

Cannot invoke 'XCTAssertEqual' with an argument list of type '([AnyEquatable>], [AnyEquatable>], file: String, line: UInt)'

[alexpopov]

It still fails to build for me, but for a different reason:
Reason: Project /Carthage/Checkouts/RxSwift/RxTests/RxTests.xcodeproj cannot be opened because it is missing its project.pbxproj file.

If I try to open the project by hand, and it complains about the same issue.

If it matters, I run carthage update --platform iOS

[kzaher]

Hi guys,

I'm little confused here. I've ran the integration tests on my machine and both CocoaPods and Carthage integrations were ok.

Are you sure you've got the correct version of Xcode selected for Command Line Tools?

[alexpopov]

I do. I tried clearing the Carthage cache as well. If I run xcodebuild -version from the command line I also get
Xcode 7.3
Build version 7D175
So I'm at a loss as to what to do.

[kzaher]

... and just to be clear, you've removed both ~/Library/Caches/org.carthage.CarthageKit/ and Carthage directories?

[alexpopov]

Just to be clear... no. I removed the latter first and the build failed. Then I removed the former, and the build failed. Removing both at once did the trick! Thanks a bunch! I guess this is the solution, at least for my particular issue.

[kzaher]

Ok, glad this was a simple solution :) Weird, but simple :)

I still get the same error:

Cannot invoke 'XCTAssertEqual' with an argument list of type '([AnyEquatable>],
[AnyEquatable>], file: String, line: UInt)'

with XCode 7.3
this is my pod file:

pod 'RealmSwift', :git => 'https://github.com/realm/realm-cocoa.git', :branch => 'swift-2.0'
pod 'RxSwift', '~> 2.2'
pod 'RxCocoa', '~> 2.0'
pod 'RxBlocking', '~> 2.0'
pod 'CocoaLumberjack/Swift'
pod 'SWXMLHash', '~> 2.1.0'
pod 'Moya'
pod 'Moya/RxSwift'
pod 'Moya-ObjectMapper/RxSwift', '~> 1.1.6'
pod 'VBFPopFlatButton'

target 'TrollTests', :exclusive => true do
pod 'RxTests', '~> 2.0'
pod 'Quick', '~> 0.9.0'
pod 'Nimble', '~> 3.2.0'
pod 'Dip'
end

i tried updating to RxSwift latest version 2.3.1 but got this error upon pod install:
[!] Unable to satisfy the following requirements:

• RxSwift (~> 2.3.1) required by Podfile
• RxSwift (~> 2.2) required by RxCocoa (2.2.0)
• RxSwift (~> 2.2) required by RxBlocking (2.2.0)
• RxSwift (~> 2.0) required by Moya/RxSwift (6.2.0)
• RxSwift (~> 2.2.0) required by Moya-ObjectMapper/RxSwift (1.1.7)
• RxSwift (~> 2.2) required by RxTests (2.2.0)

i also tried not specifying version numbers in PodFile with no success

[fpillet]

Your Podfile lists RxSwift at 2.2 but RxCocoa at 2.0. You need all versions to be the same (for RxTests as well).

[idanhaviv]

i changed all to 2.0 but still get the same error

[fpillet]

You need to use 2.3.1 with Xcode 7.3 and Swift 2.2. Previous versions of RxSwift won't compile correctly.

[kzaher]

Hi @idanhaviv ,

problems seems to be in Moya-ObjectMapper/RxSwift requesting 2.2.0 instead of 2.2.

ss.dependency "RxSwift", "~> 2.2.0"

when it should be

ss.dependency "RxSwift", "~> 2.2"

[idanhaviv]

Hi @kzaher,

if it was 2.2 while i have 2.3.1 should it work fine? anything i can do besides open an issue on Moya-ObjectMapper?
