Socket.io-client-swift: Missing required modules: 'CommonCrypto', 'zlib'

[SalvatoreAD]

I update the library and I found this error. Can you help me?

[nuclearace]

What version of the lib?

[nuclearace]

And how did you install the lib?

[SalvatoreAD]

Last version with pod

[nuclearace]

Have you done a repo update and pod update? I tested CocoaPods myself and it worked fine.

[SalvatoreAD]

I updated pod to the latest beta version. I came back to the previous version that works correctly.

[pmusolino]

Same problem here after library update to Socket.IO-Client-Swift 11 (was 10.0.1).

[nuclearace]

What other dependencies are you using? I wonder if they're conflicting.

[pmusolino]

This:

  pod 'Alamofire', '~> 4.5'
  pod 'PromiseKit', "~> 4.2"
  pod 'KeychainAccess', '~> 3.0.1'
  pod 'IQKeyboardManagerSwift', '~> 4.0'
  pod 'SwiftyBeaver', '~> 1.3'
  pod 'MGSwipeTableCell', '~> 1.5'
  pod 'DZNEmptyDataSet', '~> 1.8'
  pod 'SideMenu', '~> 2.3'
  pod 'Jibber-Framework', '~> 2.0', :configurations => ['Debug']
  pod 'Fabric'
  pod 'Crashlytics'
  pod 'PullToRefresher', '~> 2.0'
  pod 'OneSignal', '>= 2.5.2', '< 3.0'
  pod 'ObjectMapper', '2.2.7'
  pod 'Kingfisher', '3.10.2'

[nuclearace]

Hm, yeah. I wonder if there's a way to figure out which one is causing the conflict... I'm also not sure the best way to solve this issue.

[nuclearace]

I'm guessing I'll have to change the names of these modules in my fork of Starscream.

I'm having this issue too - I get the same build error as Codeido has above since updating to Socket.io 11.0. I only have one dependency aside from socket.io and Starscream, and that dependency (Polyline) doesn't use CZLib or CommonCrypto.

(I should also note that I'm using Carthage, not Cocoapods)

I was above to work around this issue by moving Carthage/Checkouts/Starscream/zlib/module.modulemap from my project directory to a different location. Now it no longer complains - which is weird, since I'm using the frameworks from the Build directory and don't have the Checkouts projects loaded in Xcode. If I move the whole Checkouts directory somewhere else I get an error complaining that CZLib and CommonCrypto cannot be found.

Any idea what is going on here? I see why this would happen with dependencies that use CZLib or CommonCrypto, but mine don't...

I had the same problem as @Codeido. I followed the technique described in Mike Weller's answer here:
https://stackoverflow.com/questions/25248598/importing-commoncrypto-in-a-swift-framework

He creates a target called CommonCryptoModuleMap which fixes the redefinition problem for CommonCrypto. I followed the same technique to create a CZLibModuleMap, with this for my Run Script:

mkdir -p "${BUILT_PRODUCTS_DIR}/zlibModuleMap"
cat < module zlib [system] {
header "${SDKROOT}/usr/include/zlib.h"
export *
}
EOF

After this my project built and I was successfully able to connect to my socket.io server running locally.

[nuclearace]

This might have been fixed in 11.1.0.

[thully]

It doesn't seem to be fixed. I still get the "Redefinition of module" errors when building with 11.1.1 and StarscreamSocketIO 8.0.4. I'm using Carthage for my dependency resolution, and I cleared the Carthage directory before the rebuild to make sure there were no residual files. I can work around this problem by deleting the Carthage/Checkouts/Starscream/zlib/module.modulemap file - then the build error goes away.

[nuclearace]

@thully @tbaranes Can you see if just adding the development branch of socket.io to your Cartfile and building fixes it? I'm trying something out.

[nuclearace]

From my testing it seems to be fixed. But knowing how package managers play with each other, I'll probably break everything else.

[nboyd-sportdx]

has anyone got this to work?

(update)...got it to work. cleaning build folder...not sure what's going on w/ xcode

[nuclearace]

@nboyd-sportdx were you using Carthage or cocoapods? If carthage did you use the development branch?

[LeonidKokhnovich]

@nuclearace I have the same issue with the following cartfile:

github "nuclearace/Starscream" ~> 8.0.4
github "socketio/socket.io-client-swift" ~> 11.1.1

[nuclearace]

@LeonidKokhnovich Try github "socketio/socket.io-client-swift" "development"

[nuclearace]

If that works I can make a new release.

[LeonidKokhnovich]

@nuclearace Thank you for such a fast support with the problem. Yes, it fixes the issue with the following cartfile update:

github "nuclearace/Starscream" ~> 8.0.4
github "socketio/socket.io-client-swift" "development"

[Nathan187]

this is working for me as well

[nuclearace]

I'll make a new release tonight then.

[Nathan187]

i'm notorious for cutting corners and not RFTM. if you can get another test case/subject before doing a release...that may help. sorry for any inconvenience and thank you for your hard work

[nuclearace]

@Nathan187 What do you mean?

[Nathan187]

just wondering if it was something i was doing wrong....but i'll drop the subject now. thanks for your hardwork

[nuclearace]

Should be fixed in 11.1.2

[hungvh1904]

Still facing issue with cocoapods :(
pod 'Socket.IO-Client-Swift', '~> 11.1.3'
pod 'Starscream', '~> 3.0.3'
