Xcode 10 - Build Error

[marcellofiore]

Using JSONWebToken (2.2.0) with Pod
I have this error when using Xcode Version 10.0, please update.

I hope in a quick update, Regards.

I have the same issue. I saw the 3.0.0 unofficial version, but there is no .podspec file. So I am a little bit bewildered. How do you suggest to use it?

[marcellofiore]

where did you find version 3.0?

[mataspetrikas]

same here, with the Pod version JSONWebToken (2.2.0)

Same issue. Maybe it helps

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.0.sdk/usr/include/CommonCrypto/module.modulemap:1:8: error: redefinition of module 'CommonCrypto'

Thats how I fixed it in the Podfile if this helps anyone:

post_install do |installer|
    
    installer.pods_project.targets.each do |target|
        
        if target.name == 'JSONWebToken'
            system("rm -rf Pods/JSONWebToken/CommonCrypto")
        end
        
    end
    
end

I needed to add some build variants for os types to the exclusion code by juchampagne
if target.name == 'JSONWebToken' || target.name == 'JSONWebToken-iOS' || target.name == 'JSONWebToken-macOS' || target.name == 'JSONWebToken-tvOS'

It appears the CommonCrypto is now part of iOS 12.

Thanks @juchampagne I added that code to the end of my podfile and my Xcode 10.1 project can now build successfully with v2.2.0 👍
