I have a similar issue. Both FacebookCore and FacebookLogin have errors and I can't import them in my project using Cocoapods.

FacebookCore

FacebookLogin

Until an update is available you can build using a legacy swift version. Using cocoa pods:

post_install do |installer|
    installer.pods_project.targets.each do |target|
        if ['FacebookCore', 'FacebookLogin'].include? target.name
            target.build_configurations.each do |config|
                config.build_settings['SWIFT_VERSION'] = '3.2'
            end
        end
    end
end

Hi @andschdk, is there a way to build using Carthage?

[andschdk]

@wangqingzhouleo, I am not totally sure about Carthage. To get going I guess you can open the affected frameworks' project file (from Carthage/Checkouts/<framework-folder> and set the Swift Language Version config in Build Settings.

Then run carthage build to rebuild the frameworks with the new config.

Work in progress currently. Hopefully support for Swift 4.2 should be released very shortly.

Ok . i'm waiting for the new version

[sercesh]

Hi, thank you @andschdk. I am closeing this issue.

[codytwinton]

New version has been released

[StormKop]

Thanks Cody! Appreciate the prompt response!

Hi guys, I tried using pod install of FacebookCore and FacebookLogin but I'm receiving similar errors after the new version has been released.

[muthukrishnanOCS]

@StormKop Are you using the Cocoapods 1.6.0.beta.1?
If yes please go back to 1.5.3 then it should work or try pod update

[andschdk]

Remember to pod repo update.
I face no issues with the current version.

[StormKop]

@muthukrishnanOCS I'll have to check it out but I don't think so. Thanks for the advice!
@andschdk ahh! good point. I didn't do a pod repo update. All I did was to add the pods into my Podfile and did a pod install. Just out of curiosity, why should we do a pod repo update ? Thanks in advance.

[StormKop]

Thanks for the advice @muthukrishnanOCS and @andschdk. I was running on cocoa pods version 1.5.3 and I tried pod repo update but it didn't work.

I did a pod update and everything worked!

Guys I am running swift 4.2 on Xcode 10.. I have installed the following in my pod file

pod 'FacebookCore'
pod 'FacebookLogin'
pod 'FacebookShare'

then.. i try to import FacebookShare . ... and then it fails.. it does not even auto-complete the module name for me.. Any ideas? I see above this was fixed but is there any additional work that has to be done other than pod install and import? I have also pod repo update and pod update after i install and neither help

Thanks

[Deg5112]

nevermind.. after a couple hours of the painful troubleshooting.. it just started working, removed all pods... re-installed.. closed Xcode.. cleaned.. rebuilt.. annoying how inconsistent this is.. any tips lemme know, graci

[codytwinton]

@Deg5112 - These issues could be related to Xcode 10, which uses the new Xcode build system by default. It is incompatible with the legacy build system and can cause a lot of ambiguous build errors.

Login with swift 4.2 version of the SDK (library version 4.39.0) doesn't work. Always get this exception -
Error Domain=com.facebook.sdk.core Code=3 "(null)" UserInfo={com.facebook.sdk:FBSDKErrorDeveloperMessageKey=Unknown error building URL.})

@yesnoyes I have the same error, did you solve the problem?

I was using 9.2 xcode but I just updated and after updated with 10.1 xcode I also update Usabilla sdk(previous 4.0 and now 5.0) but When I try to archive I got an error. And didn't get any solution.

[yesnoyes]

@babuiglesiaskhan This Ticket is for the bug related to Facebook login. However I can give you a clue to narrow down your problem -
First you should remove the Usabilla sdk's implementation from your code and test if "import usabilla" works at the first place, if it doesn't work, you should report it to usabilla developers community.
If "import usabilla" doesn't give you any error, there is possibility that with their new sdk they may have changed the implementation code.
