Cocoapods: `pod spec lint` fails after Cocoapods 1.0 update

Created on 14 May 2016  Â·  23Comments  Â·  Source: CocoaPods/CocoaPods

When I try to run pod spec lint on my project I get the following error:

- ERROR | [iOS] unknown: Encountered an unknown error (Simulator iPhone 4s is not available.) during validation.

Report

What did you do?

Ran pod spec lint, and also pod spec lint --use-libraries.

What did you expected to happen?

Pass the linter check.

What happened instead?

Failed with:

 - ERROR | [iOS] unknown: Encountered an unknown error (Simulator iPhone 4s is not available.) during validation.

Analyzed 1 podspec.

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

And I have the iPhone 4s Simulator on Xcode working just fine.

@neonichu looks like a fourflusher issue?

What's the output of xcrun simctl list on your system?

I tried deleting the two unavailable devices using xcrun simctl delete <device_id>, but it didn't give any results.

agyorev picture agyorev on 14 May 2016

Can you also please share the spec you were linting or at least its platform information if you prefer to keep it private?

neonichu picture neonichu on 14 May 2016

Oh wait, that list doesn't show any actually usable simulator devices. Curious that you still have any inside Xcode.

neonichu picture neonichu on 14 May 2016

I looked at the output of xcode-select -p and it turned out it was pointing to a beta release version, so then I just did xcode-select --switch to the latest updated one, ran pod spec lint again and it worked.

@ishaq which version of Xcode are you using to get that output? The issue is that your simulator is called "iPhone 4s iOS 9.3" whereas CocoaPods is looking for one which is called "iPhone 4s" (default naming of Xcode 6.x and 7.x).

neonichu picture neonichu on 30 May 2016

Thank you @neonichu, I am using Xcode 7.3.1 but I was using simulator_populator script. I have changed it to produce default naming and it now works.

I am sorry for raising false alarm, when I couldn't find a solution through google, I thought may be it was a bug in CocoaPods. Sincere apologies.

ishaq picture ishaq on 30 May 2016

I ran into this issue. I didn't have a TV simulator. Added one and then it worked.

soffes picture soffes on 4 Jun 2016

I ran into the same problem with Xcode 7.3.1 (xcode-select points to it, too).
I actually removed bunch of unused devices a while ago.
I can confirm that adding iPhone 4S simulator in Xcode → Devices resolves the problem
Not sure why does spec lint rely on that particular simulator though.
Would be happy to provide more info on my particular setup if needed

Not sure why does spec lint rely on that particular simulator though.

This got fixed in master, it'll now determine the lowest supported sim in the next release

re: Xcode 8, I updated to 1.1.0.rc.2 and problem went away.

gabriel picture gabriel on 18 Sep 2016

This worked for me (with Xcode 8)

  1. Install the Cocoapods release candidate.

sudo gem install cocoapods --pre

  1. Use it when running spec lint

pod _1.1.0.rc.2_ spec lint

I ran into the same issue with XCode 8. I installed 1.1.0.rc.3 and it still did not work. Then I uninstalled all older cocoapod versions with sudo gem uninstall cocoapods and then it worked again.

I installed 1.1.1 (from 1.0.1) and this issue was fixed for me.

I had two versions of Xcode 7.3 and 8. it was using 7.3.

I just used sudo xcode-select --switch /Applications/Xcode.app to make the default Xcode 8 and it worked

I've seen this issue before:
-El Capitan
-XCode 8.2.1
-Cocoapods 1.0.2

The solution was to run sudo gem install cocoapods and update to 1.2.0.
