FBSDKLoginKit can not find headers under 1.0.0

[fcobia]

The 1.0.0 beta breaks the Facebook SDK. If you wither include the pod FBSDKCoreKit you can not reference the header files using "#import <FBSDKCoreKit/FBSDKCoreKit.h>."

If you include the pod FBSDKLoginKit, it will not compile because it can not access the FBSDKCoreKit headers.

I downgraded to 0.39.0 and it works with no errors.

Please share a project we can use to debug the issue :)

[fcobia]

All you have to do is create an empty swift project and add "pod 'FBSDKLoginKit" to the Podfile.

I did create an empty project that you can see: https://github.com/fcobia/CocoaPodsTest

Thanks!

Took a quick look, seems like the issue is that the wrong copy headers build phases are being generated, e.g a "Copy .. Public Headers" which copies most of the SDK's headers into "$(PUBLIC_HEADERS_FOLDER_PATH)/.."

[segiddins]

actually, Facebook’s podspec is wrong
it wouldn’t even lint using the beta
they have to push a new version with a fix
since they have headers that arent in the header_mappings_dir

[neonichu]

ah, totally missed that they are using header_mappings_dir somehow. Might make sense to warn/error in that case?

[segiddins]

The linter already checks for that

👍

(Already as in, as of the 1.0 beta)

Hi, I updated the header_mappings_dir one level higher which seems to resolve the issue initially,

pod 'FBSDKCoreKit', :podspec => 'https://raw.githubusercontent.com/chrisp-fb/facebook-ios-sdk/master/FBSDKCoreKit.podspec'

but it causes non-modular import errors with Cocoapods 0.39 (in a sample that uses FBSDKLoginKit and FBSDKShareKit as well)

"/Pods/FBSDKCoreKit/FBSDKCoreKit/FBSDKCoreKit/FBSDKAppLinkResolver.h:26:10: Include of non-modular header inside framework module ‘FBSDKCoreKit.FBSDKAppLinkResolver’ "

We've run into this before for different reasons (and it's odd that it breaks in 0.39). I tried a couple things include making Bolts an explicit of our LoginKit and ShareKit as well as removing header_mappings_dir in favor or proper private_header_files without luck. So, for now I'm going to simply set CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES to YES for our LoginKit and ShareKit specs to be compatible for both Cocoapods 0.39 and 1.0-beta2. Let me know if you have other ideas.

@chrisp-fb this might just be an instance of #4420

[chrisp-fb]

Interesting thread - but there's definitely something with header_mappings_dir as well; i.e., I'm using Xcode 7.2 consistently. Our current published podspec works fine with Cocoapods 0.39. It fails with Cocoapods 1.0-beta2 with the header_mappings_dir validation. So modifying the header_mappings_dir fixes it for Cocoapods 1.0-beta2 but then causes the non-modular import error in 0.39.

[neonichu]

Yah, header_mappings_dir was deliberately changed for 1.0 since it was working inconsistently before, see #4267.

@chrisp-fb Is there any anywhere I can track the work on this?

FBSDK was working for me in the Beta 1.0 release, but is now broken in the 1.0 release. I have FBSDKShareKit/CoreKit 4.11.0 installed but get the 'FBSDKShareKit/FBSDKShareKit.h' file not found

[Noobish1]

Having this issue as well with Cocoapods 1.0 and FBSDKCoreKit 4.12.0 and 4.11.0.

[hijamoya]

Having the same issue, please help!

[chrisp-fb]

I'm not able to reproduce the problem and am able to create and build a new swift app with a Podfile that installs all the FBSDK pods correctly. Can you file a report to developers.facebook.com/bugs with additional details like the Podfile and versions of all the tools you're using? If possible, try to include a sample project that reproduces the issue.

I'm using Xcode 7.3.1 and Cocoapods 1.0.0

This appears to be some issue between CocoaPods and XCode. I tried to reproduce the problem I was seeing with a new project and was unsuccessful. Given that I tried removing the FBSDK from my project entirely. Once the FBSDK was removed I built and now a different Pod was failing to build due to a missing header. At this point I started digging through the active CocoaPod issues and found #4950. The solution seems to be remove all pods, nuke pod cache, nuke XCode's derived data for the project, and reinstall Pods.

TL;DR

rm -rfd *.xcworkspace
rm -rfd Pods
rm Podfile.lock
pod cache clean --all
rm -rfd ~/Library/Developer/Xcode/DerivedData/*
pod install

For people moving from Carthage to Cocoapods make sure to remove the Carthage references of the FBSDKCoreKit from the Link Binary With Libraries under Build Phases option.
