IOS openid4vc example app - No such module shared

[c0ball]

Hey everyone,

when I try to run the IOS openid4vc example app in Xcode, I receive an error in the ContentView, that the import of the shared library can not be resolved with the following error: No such module shared.

I've tried running pod install, which resulted in the following error: Analyzing dependencies [!] No podspec found for 'shared' in '../shared/build/cocoapods/publish/debug/shared.podspec'

Therefore I would like to know, how I can build the required shared library for the ios app.

To Reproduce

Steps to reproduce the behavior:

1. git clone https://github.com/walt-id/waltid-identity.git
2. Open iosApp.xcodeproj in Xcode
3. Press the "Run" button

Thanks for your help🙏

Hi @c0ball

do this and try again.

$ cd waltid-identity 
$ ./gradlew -PenableIosBuild=true :waltid-applications:waltid-openid4vc-ios-testApp:shared:generateDummyFramework
$ cd waltid-applications/waltid-openid4vc-ios-testApp/iosApp/
$ pod install

Let me know if you need any further help.

Best
Ale

Hey @alegomes

thanks for the quick reply, unfortunately this does not solve my issue.

I was able to do run the gradlew build using your command,
but when running pod install in the waltid-identity/waltid-applications/waltid-openid4vc-ios-testApp/iosApp
directory I receive the same error as before:

➜  iosApp git:(main) pod install
Analyzing dependencies
[!] No podspec found for `shared` in `../shared/build/cocoapods/publish/debug/shared.podspec`

[alegomes]

Could you, please share with me the result of these 3 commands?

$ ls -l waltid-identity/waltid-applications/waltid-openid4vc-ios-testApp
$ ls -l waltid-identity/waltid-applications/waltid-openid4vc-ios-testApp/share
$ ls -l waltid-identity/waltid-applications/waltid-openid4vc-ios-testApp/iosApp
$ ls -l waltid-identity/waltid-applications/waltid-openid4vc-ios-testApp/iosApp/iosApp

thanks

[c0ball]

Thanks again for the quick reply.

*In the second command, I changed share to shared.

[alegomes]

In the second command, I changed share to shared.

Ooops. Sure. My mistake.

This command completed successfully?

cd waltid-identity && ./gradlew -PenableIosBuild=true :waltid-applications:waltid-openid4vc-ios-testApp:shared:generateDummyFramework

Can you share the output?

thanks
Ale

[c0ball]

Sure, here it is.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.10.2/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Ok. So, let's do this:

In the file waltid-applications/waltid-openid4vc-ios-testApp/iosApp/Podfile,

change

../shared/build/cocoapods/publish/debug/shared.podspec

to

../shared/shared.podspec

and try pod install again.

So after changing the path, I was able to run pod install

iosApp git:(main) ✗ pod install
Analyzing dependencies
Downloading dependencies
Installing JOSESwift (3.0.0)
Installing shared (1.0)
Generating Pods project
Integrating client project

[!] Please close any current Xcode sessions and use `iosApp.xcworkspace` for this project from now on.
Pod installation complete! There is 1 dependency from the Podfile and 2 total pods installed.

[!] The `iosApp [Debug]` target overrides the `ENABLE_USER_SCRIPT_SANDBOXING` build setting defined in `Pods/Target Support Files/Pods-iosApp/Pods-iosApp.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

[!] The `iosApp [Release]` target overrides the `ENABLE_USER_SCRIPT_SANDBOXING` build setting defined in `Pods/Target Support Files/Pods-iosApp/Pods-iosApp.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

After opening the iosApp.xcworkspace and trying to compile the app, I receive the error Cannot find 'Uuid' in scope which is caused by line 30 of ContentView.swift

kid = Uuid.random().uuidString

to fix this error, I replaced it like so:

kid = UUID().uuidString

But now I do receive the following error:

Line 34 of ContentView.swift

[alegomes]

Cool. We are moving forward.

Give me some time to investigate this (I'm not a Swift dev).

[c0ball]

Hey @alegomes, I just wanted to ask if there is an update yet
