Could not find or use auto-linked library 'swiftWebKit'

[kockok]

Description

Error raised when building the app.

Steps to Reproduce

1. run build in the xcode app.
2. error when building

Expected behavior: build the app without such error.

Actual behavior:

ld: warning: Could not find or use auto-linked library 'swiftWebKit'
Undefined symbols for architecture arm64:
  "__swift_FORCE_LOAD_$_swiftWebKit", referenced from:
      __swift_FORCE_LOAD_$_swiftWebKit_$_lottie_react_native in liblottie-react-native.a(ContainerView.o)
      __swift_FORCE_LOAD_$_swiftWebKit_$_lottie_react_native in liblottie-react-native.a(AnimationViewManagerModule.o)
     (maybe you meant: __swift_FORCE_LOAD_$_swiftWebKit_$_lottie_react_native)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Exactly the same after upgrading to RN 0.64

[VicFrolov]

Same issue here on RN 0.64.

I see this was recently merged (82a0864), but problem persists after pointing package to master, and npm installing / pod install

[emilioicai]

@VicFrolov This issue is my first prio as it's blocking the release of v4.0.0 but I'm afraid I cannot reproduce the error. Can you make sure you are using the master branch and clean your cache before doing npm install? I'm going to need your help to fix this.

@emilioicai The solution for me was to create an Objective-C bridging header in the iOS project.

[emilioicai]

@jctf would you mind sending a PR with the file for the bridging header? Thanks!

[jctf]

@emilioicai it might be easier to describe the steps to take when you upgrade to RN 0.64.
There are other 3rd parties libs out there that documented exactly these steps.
A great how-to can be found -> https://teabreak.e-spres-oh.com/swift-in-react-native-the-ultimate-guide-part-1-modules-9bb8d054db03
You would only have to take the steps till the prompted where you choose to configure Objective-C Bridging Header.

Hope that helps.

[emilioicai]

oh, you mean the bridging header on the main project, not on the lib. Ok, I will update the documentation accordingly. Thanks!

[kockok]

@emilioicai Simply creating an empty swift file and bridging not working for me...

[4yki]

@kockok , make sure to create File.swift + bridging header on the correct level

• In the Group dropdown, make sure to select the group CounterApp, not the project itself.

Also add "$(SDKROOT)/usr/lib/swift\" to LIBRARY_SEARCH_PATHS can help if you want to remove File.swift

Works for me, but needed to remove the trailing "".

[aescobar-icc]

Just open your project/ios with xcode, then add a new swift file and that's it!! your problem is solved.
at least it worked for me

Here works to me, open your project/ios with xcode, add a new swift file with bridging-header.

[ecklf]

Faced the same issue in XCode 13 beta 2 and iOS 15. Can confirm adding a new file with a bridging header works.

[ibrahimyolbir]

Hello @ecklf what do you mean by Can confirm adding a new file with a bridging header works.. can you explain more. Thanks
by the way i have the following error

ld: warning: Could not find or use auto-linked library 'swiftWebKit'

Figured this out. There is a new library in Xcode 12 that needs to
 be added to the Link Binary with Libraries phase call libSwiftWebKit.tbd. 
Error went away after adding this.

Unfortunately, adding this library breaks compilation with Xcode 11,
 so you'll have to add & remove it depending on which version of Xcode you're using.

how to do that please ?

The following is your project structure:

• your-react-native-project
  |- ios
  |- android

  the content the ios folder is an xcode project

  you must to open this folder with the xcode and then add a new file swift file

[rush86999]

Bridging header file no longer works any alternative?

thanks. it worked for me in react-native 0.64.0 and xcode 12.5

[Saqib92]

creating File.swift is not working in xcode 13.

[patlux]

I already had a File.swift in my project. I upgraded from 0.66 to 0.67 and got the error mentioned by the thread author.

My solution was to delete the following path from the LIBRARY_SEARCH_PATHS setting as you can see with React Native Upgrade Helper:

Go into Xcode and delete the following line:

facebookarchive/react-native-fbsdk#755
