Swift 3.0 - No such module

[Goule]

Hello,

I'm trying to build my project with 3.0, but seems to be not possible at this time ?

I tried with :
pod 'p2.OAuth2', :git => 'https://github.com/p2/OAuth2', :branch => 'develop'

But got this :

Have you any solution ? :-)

[p2]

Ah CocoaPods. I need to update the podfile and define NO_MODULE_IMPORT; let me push version 3.0 officially.

[Goule]

Okey thank you :-)

Please, keep me in touch in this issues when it's done !

[p2]

I have not yet pushed version 3.0 since CocoaPods seems to want to use Swift 2.3 for whatever reason, but I've updated the podspec on the develop branch. Can you try again?

[Goule]

Same issue in OAuth2 class now.

But pod passing to 3.0.0 from 2.2.8.

[leo150]

Same issue here
pod 'p2.OAuth2', :git => 'https://github.com/p2/OAuth2.git', :branch => 'develop'

[p2]

Just pushed an updated podspec, can you try again?

[leo150]

@p2, thanks you, that error is fixed. Current state:

.../Pods/p2.OAuth2/Sources/Base/OAuth2KeychainAccount.swift:58:11: Use of undeclared type 'KeychainGenericPasswordType'
.../Pods/p2.OAuth2/Sources/Base/OAuth2KeychainAccount.swift:30:31: Use of undeclared type 'KeychainGenericPasswordType'
...Pods/p2.OAuth2/Sources/Base/OAuth2KeychainAccount.swift:71:12: Use of unresolved identifier 'fetchFromKeychain'

[Goule]

Same error, look to be an error with SwiftKeychain library !

[p2]

The sources for the keychain classes are in the submodule, the .podspec defines :submodules so it should check it out. It also defines the path to SwiftKeychain/Keychain/Keychain.swift so that should work as well. Dammit...

[leo150]

That submodule project uses Swift2. Maybe it will be better to fork it or copy to OAuth2.

[p2]

It is forked and now on Swift 3. All works well in Xcode, not sure what CocoaPods is doing.

I've changed sourcefile order in the podspec, does that help?

[Goule]

I tried again and same problem :/

[leo150]

I've add
pod 'p2.OAuth2', :git => 'https://github.com/p2/OAuth2.git', :branch => 'develop', :submodules => true
and get

$ pod update p2.OAuth2
Updating local specs repositories

Unable to checkout '3734015afd390c08e94789cb7e116d83f9e0247c' in submodule path 'SwiftKeychain'

Maybe it helps to find solution

[p2]

Yes, I have the same problem, even after pod clean p2.OAuth2. The reference is correct, I'm not sure what it's caching.

[p2]

Alright, I also changed the submodule on master, and now it seems to work with this in the Podfile:

pod 'p2.OAuth2', :git => 'https://github.com/p2/OAuth2', :branch => 'develop', :submodules => true

Maybe clean the cache first:

pod cache clean p2.OAuth2
pod update

[leo150]

Thank you. I didn't understand what you did, but it works :D

[Goule]

It's ok now ! :D

Thank you.

[p2]

🙂

As you saw, the original SwiftKeychain is not on Swift 3. So I forked and, on the develop branch, pointed the submodule to the forked location. Apparently CocoaPods does something different, pointed to the old location and there the Swift 3 update is not available obviously. What I did shouldn't work (strictly git speaking) but it does... 👍🏼

Thanks for testing to the both of you! I'll keep this open for others to see.

Has the v3 pod spec been taken down? I'm sure I had it building through Cocoapods with version 3 of your library but running a pod install with pod 'p2.OAuth2', '~> 3.0' throws the following error:

[!] Unable to satisfy the following requirements:

- `p2.OAuth2 (~> 3.0)` required by `Podfile`

None of your spec sources contain a spec satisfying the dependency: `p2.OAuth2 (~> 3.0)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

Not too much of an issue as I can point to your repo to pull the code, but I could have sworn I pulled down version 3.0 yesterday through Cocoapods!

[p2]

No, I'm unable to post 3.0 because of CocoaPods/CocoaPods#5880 . You can use the pod with this in your Podfile:

pod 'p2.OAuth2', :git => 'https://github.com/p2/OAuth2', :submodules => true

@p2 Maybe you should, at least for now, update the readme with this instructions? Currently when a new user tries installing it, it fails and needs to search to maybe find this issue.

[mxcl]

You can fork https://github.com/CocoaPods/Specs and update manually, I'm doing this for PromiseKit since this has been going on for a while now.

[p2]

Thanks, I probably should. What a piece of crap.

[mxcl]

You have to ping a maintainer to get them to merge it.

[liltimtim]

May I suggest moving this to an issue with a more clear title? I arrived here via google and didn't know why it was pointing me here :) but this did solve my problem at least!

pod 'p2.OAuth2', :git => 'https://github.com/p2/OAuth2', :submodules => true

the Swift 3.0 transition has been...rocky....to say the least it seems for everyone.

[floriangbh]

The solution for Swift 3.0 is in the README file :-)

[p2]

@liltimtim what have you been searching for, OAuth2 and CocoaPods? Maybe I can adapt the title. Installation via CocoaPods is explained st the bottom of the readme; I don't think CocoaPods is a great system for Swift, since we can use frameworks in iOS it's overkill.

[liltimtim]

@p2 Maybe Swift 3.0 - No such Module error? I was receiving similar error as the op. after implementing your solution it was fixed.

[p2]

The bug in CocoaPods has been addressed in CocoaPods 1.1rc3 and I have been able to push version 3.0.0 for Swift 3.0. You should now be able to use the standard procedure to use OAuth2 via CocoaPods:

pod 'p2.OAuth' '~> 3.0'

[0xTim]

Have updated my Podfile and all seems to be working, many thanks!

Hi, I've tried through cocoa pods and get the same issue. Has this been tested for swift 4? I get the "no such module p2.OAuth2" error though when I go to project settings/build phases/ link binary.../ and press add, p2.OAuth 2 is in the linkable frameworks. Also, via cocoa pods, there are a lot of errors as functions and properties are internal and cannot be reached. Any help greatly appreciated

[p2]

This issue is closed, please open a new issue and provide more details if v 4.0.1 doesn't work for you via CocoaPods.
