Attempting to push or lint a library built with Xcode 8 (Swift 3) fails.

What did you do?

I tried to push SwiftyUserDefaults

It fails with a cryptic error:

$ pod _1.1.0.rc2_ trunk push

    - ERROR | [tvOS] unknown: Encountered an unknown error (Invalid OS `tvos`, valid values are ios, watchos) during validation.

[!] The spec did not pass validation, due to 1 error.

Same thing happens with lib lint:

$ pod _1.1.0.rc2_ lib lint --no-clean                                                                                              ~/Documents/Open Source/SwiftyUserDefaults

The problem appears to be with CP-generated Xcode project for verifying the pod — it doesn't get the bundle identifier set in build settings: https://twitter.com/radexp/status/776196022548717569

Hrm, I've given this a run on my machine and I'm not seeing this:

OK, I'm investigating further.

• I cleaned all of DerivedData, restarted Xcode, no change.
• I opened the project, added the bundle identifier build setting manually. Still fails.

• I set the development team. No change.
• I put on --verbose while doing lib lint. iOS and OS X seems to go fine. it's just tvOS.

And here's something interesting in those error messages:

Failed to create provisioning profile. There are no devices registered in your account on the developer website. Plug in and select a device to have Xcode register it.
No profiles for 'test.cocoapods.blah' were found:  Xcode couldn't find a provisioning profile matching 'test.cocoapods.blah'.
Code signing is required for product type 'Application' in SDK 'tvOS 10.0'

Could it be that Xcode needs to generate a provisioning profile to build this test project, but can't do so because none of my development teams actually have any tvOS devices in Apple Developer Portal?

I checked and indeed I have no Apple TVs in ADP. If someone sent me a valid Apple TV UUID I could check if this fixes it…

[fengqiangboy]

I have the same issue

Digging deeper.

@austinate was kind enough to lend me his Apple TV UUID.

Validation still fails the same way:

SwiftyUserDefaults » master » pod _1.1.0.rc2_ lib lint --no-clean

[!] SwiftyUserDefaults did not pass validation, due to 1 error.

When I open the Xcode project, it too fails. I still have to add the bundle identifier and set the development team manually, and I get further this way, but still fails like so:

Which could be an artifact of building manually instead of via xcodebuild, but it's still strange, because @orta says the validation passes just fine for him...

I'm running out of ideas of how our setups could be different:

• OS X version (I'm on El Capitan)
• number of development teams (I have two)

[radex]

Okay, I'm a total dummy.

The issue was that I didn't have any Apple TV simulators set up. That's it. All the other errors were unrelated.

In retrospect, I should've paid more attention to the --verbose logs:

    - ERROR | [tvOS] unknown: Encountered an unknown error (Invalid OS `tvos`, valid values are ios, watchos
/Users/radex/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/fourflusher-1.0.1/lib/fourflusher/find.rb:85:in `usable_simulators'
/Users/radex/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/fourflusher-1.0.1/lib/fourflusher/find.rb:67:in `simulator'
/Users/radex/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/fourflusher-1.0.1/lib/fourflusher/xcodebuild.rb:7:in `destination'

The error comes from fourflusher, not xcodebuild.

Thanks for writing this down!

I ran into the exact same thing. But with the help of this issue, it didn't cost me much time. 😄
