Trying and failing to make OMGHTTPURLRQ Carthage compatible

[mxcl]

OMGHTTPURLRQ now has an xcodeproj, it builds an iOS framework. When I try to make Carthage use it I get this output:

$ carthage update --verbose
*** Fetching OMGHTTPURLRQ
*** Checking out OMGHTTPURLRQ at "2.1.1"
*** xcodebuild output can be found in /var/folders/9p/55y6r8hs3yz2qkhvf74gc0gh0000gn/T/carthage-xcodebuild.h7Khzj.log
*** Building scheme "OMGHTTPURLRQ" in OMGHTTPURLRQ.xcodeproj
** BUILD FAILED **


The following build commands failed:
    Check dependencies
(1 failure)


$ cat Cartfile
github "mxcl/OMGHTTPURLRQ"
$ ls Carthage/Build/
$

I figure I am missing something key, but I can't find docs for the framework-owner portion of Carthage. Thank you.

Did you check the xcodebuild output? The log file has more detailed information about what caused the build to fail.

I see, I assumed it was a Carthage dependency issue. My bad assumption.

CodeSign error: code signing is required for product type 'Unit Test Bundle' in SDK 'iOS 8.1'

Is there something I must do so it doesn't build the test target?

[mxcl]

As further information. I can build the framework when I open the project in Xcode itself.

[mattrubin]

Carthage builds a "fat" framework which can be used both in the simulator and on device. In addition, xcodebuild doesn't allow you to build a device-compatible framework which isn't code-signed. Thus, you need to have a code-signing identity specified (for the Release configuration) for Carthage to build a framework.

You can find more discussion in this issue.

[mattrubin]

Taking another look at the build log, it appears the code-signing failure is on the OMGTest target, and not on OMGHTTPURLRQ. I'm not sure why Carthage is building what I assume is a test bundle, but you may be able to alter your project schemes to avoid building the tests as a dependency of the framework.

Also: You can run carthage build --no-skip-current in the framework's project directory to test Carthage compatibility without having to set up a Cartfile and download dependencies in another project.

I believe the code signing stuff is set up correctly, but indeed, it is failing trying to build the test target, I'll look further, thanks.

[mxcl]

FFR I fixed this by unchecking "Find implicit dependencies" in the scheme management settings for the Build section.

So Xcode itself decided the tests were an implicit dependency of the main target. Thanks Xcode.

Thanks for your help.

Silly Xcode... 😕

Glad I could help!

Thanks for helping out, @mattrubin!
