Can you provide a sample project that reproduces the issue? Your environment looks to be in good shape, so there's nothing I can think of to recommend there unfortunately. Thanks!

[saleemsangi]

Is there possibility that xcodebuild is using older version of Xcode or SDK before Swift 3? I am getting errors like
error: use of undeclared type 'Error'

I am able to build the project through Xcode interface.

[benasher44]

That's quite possible! I would try running xcodebuild -version to ensure that your terminal set to use Xcode 8.1 as expected, and then you could try running xcode-select --install to ensure you have the most up-to-date CLI tools.

[saleemsangi]

yes its showing
Xcode 8.1
Build version 8T61a

and CLI tools are already installed.

So just for testing I changed Command Line Tools from Xcode 8.1 to Xcode 8.0 and all the errors are gone but gettinga new error.

- ERROR | [iOS] unknown: Encountered an unknown error (/usr/bin/xcrun simctl list -j devices

[benasher44]

It feels like something is wrong with your Xcode install. Can you try re-installing Xcode? I know that's a big ask, but I'm not sure what else to do at this point. That's what I'd be doing anyway.

[saleemsangi]

sure, i"ll try that. Thanks for the help.

[saleemsangi]

Deleted all the versions of Xcode and installed just Xcode 8.1, still getting the same error. :(

[benasher44]

Hm. Okay. I'm out of ideas. If you can provide a sample project and podspec, that'd be much appreciated. Otherwise, I'm not sure what other suggestions I can give.

[benasher44]

@saleemsangi did you mean you were still getting the simctl error?

[saleemsangi]

@benasher44 Yes by using Xcode 8.0 Command Line Tools all the xcodebuild errors went away and was just getting simctl error.
Any thoughts on fixing simctl error?

[benasher44]

This might sound silly, but have you tried restarting your machine? simctl requires one or more services to work properly, and I've resolved issues like this just by restarting.

[saleemsangi]

Yes tried that too. :)

Seems like something is wrong with my project. Created a new Single View App, added podspec file and it passed the validation. I'll keep digging.

[benasher44]

Great to hear! I'm going to close this, since it doesn't appear to be a CocoaPods issue. But, please keep us updated when you figure out what the issue is. Thanks for filing!

[saleemsangi]

@benasher44 I changed my code from swift 3 to swift 2.3 and its passing the validation. Somehow xcodebuild is using swift 2.3 even though its set to Xcode 8.1.

[benasher44]

You can try passing --swift-version=3.0.1 to pod lib lint for Xcode 8.1 to see if that helps.

[saleemsangi]

@benasher44 By using --swift-version=3.0.1 all the xcodebuild errors are gone. 🗡

Now getting one more
“Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.

* BUILD FAILED *

I have converted the project to swift 3 and have set the use legacy flag to NO in build settings.

[saleemsangi]

YaY!!!

pod lib lint --swift-version=3.0 => passed validation
pod lib lint --swift-version=3.0.1 => gives SWIFT_VERSION error

[benasher44]

Glad you got it working, and we appreciate you posting your solution! Thanks!

[saleemsangi]

@benasher44

I am trying to push the pod to my personal repo
pod repo push MyPod MyPod.podspec --allow-warnings --verbose

but getting the swift 3 errors again.

passing --swift-version fixed the same issue in the pod lint.

[benasher44]

You should be able to provide the same flag to pod repo push. Will it not allow you to do that?

[saleemsangi]

It gives me an error
[!] Unknown option: --swift-version=3.0

and provides the list of options available

[benasher44]

Hm. That's probably an oversight. And the .swift-version file still doesn't work? It's contents should just be "3.0" without quotes (i.e. not SWIFT_VERSION=3.0 or anything like that). I'll tag this ticket as a defect though, since pod repo push should definitely allow --swift-version

[saleemsangi]

So I already have .swift-version file and it has 3.0 in there.
pod lib lint was failing even with .swift-version file until I passed --swift-version in the terminal

[benasher44]

Can i see the contents of your .swift-version file (cat .swift-version)?

[saleemsangi]

2.3

I think I had changed from 3.0 to 2.3 for testing and forgot.

Now updated it to 3.0 and its working. I should have checked it. :(

[saleemsangi]

You can close the issue anytime you want. Thank you for all the help.

[benasher44]

No problem thank you!

[benasher44]

Note for others that want to contribute: follow up here is to ensure pod trunk push and pod repo push accept the --swift-version arg.

[dnkoutso]

@benasher44 I believe pod trunk push already supports this argument, I opened up a PR for pod repo push command

[benasher44]

Closing via #6288

xcrun: error: unable to find utility "simctl", not a developer tool or in PATH
) during validation.

[!] ContactsWrapper did not pass validation, due to 1 error.
[!] The validator for Swift projects uses Swift 3.0 by default, if you are using a different version of swift you can use a .swift-version file to set the version for your Pod. For example to use Swift 2.3, run:
echo "2.3" > .swift-version.

You can use the --no-clean option to inspect any issue.

I solved this problem by entering

Xcode > Preferences > Locations
And assigning the Command Line Tools

[benasher44]

Hi @yangweicong! Thanks for letting us know! It appears simctl isn't installed properly or isn't in your PATH. You should check to make sure your CLI tools are setup properly (run xcode-select --install and to ensure you're using an up-to-date version of Xcode. If you're still experiencing this issue, I recommend posting in Stackoverflow, as this doesn't appear to be an issue we could fix by patching CocoaPods. If you disagree, I recommend opening a new issue and fully filling out the issue template. Have a great day!

[yangweicong]

@benasher44 OK

[agordeev]

swift-version does the trick for Swift 4 too:

pod trunk push --swift-version=4.0
