OpenSSL.framework not found in PackagesFrameworks directory

[priska96]

While developing an expo module to read the PD file from the eGK via NFC and your OpenHealthCardKit I ran into the following issue:

Some context and folder structure:
I am building this module so I can later install it in my expo app and it works just fine with my config plugin and everything.
A thing that needs to be optimized however is the dependencies to the gematik OpenHealthCardKit.

/gk-nfc-reader
- ios/
-- OpenSSL.framework
-- GKNFCReader.swift
-- GKNFCReeader.h
-- all the other files for my native code
- node_modules/
- plugin/
-- src/
---index.ts //this is my expo config plugin
- Resources/ // this folder keeps my localization files for my native siwft module
- src/ // my folder for integrating my native module in RN
-- index.ts
--RNGKNFCReader.ts
-- useReadPersonalData.ts
- app.plugin.js // entry point for the expo config plugin
- -gk-nfc-reader.podspec
- package.json
- other package realtes files

So far I handled the dependencies manually and added the frameworks (HealthCardAccess.framework, NFCCardReaderProvider.framework, etc.) to my module ios folder and referenced them in my .podspec like so:

s.vendored_frameworks = 'ios/*.framework' #include all frameworks from gematik

That was due to the fact that your frameworks can only be added via SPM and there was no way to add an spm_dependency to a .podspec so far. I need the podspec since I am building a react native npm package.

A week ago react native added spm_dependency for the podspec. Which is great because now I can reference your frameworks like so:

spm_dependency(s,  
     url: "https://github.com/gematik/ref-OpenHealthCardKit", 
     requirement: {kind: "upToNextMajorVersion", minimumVersion: "5.6.0"}, 
     products: ["CardReaderProviderApi", "HealthCardAccess", "HealthCardControl", "Helper", "NFCCardReaderProvider"] 
   ) #include gemtaik frameworks via spm

However, I run into this error with OpenSSL.framework. I am not very familiar with xcode and the build process.

It assumes that the framework should be found in the PackagesFrameworks folder of my module that I am building (the gk-nfc-reader). Which is not the case though. I am wondering if there might be some bug on your side when the HealthCardAccess and HealthCardControl frameworks are build ?

I temporarily fixed this issue by adding you OpenSSL.framework again to my ios folder and added the dependency to the .podspec. However that's not a good solution, as I need to manually keep the framework up to date.

I hope this information can help you somehow to figure out what I am doing and what might be wrong with the build process of the OpenHealthCardKit in case there is a bug.

Actually, you can check out the full code here

Unfortunately I'm not too familiar with CocoaPods.

OpenSSL-Swift is a precompiled framework that is transitively needed by OHCKit. Maybe CocoaPods needs some more info and it helps if you explicitly express this dependency in another spm_dependency similar like we are doing in our E-Rezept-App's Package.swift https://github.com/gematik/E-Rezept-App-iOS/blob/4e62168b8599b9d404bc6c820eb53e080b6e6714/Package.swift#L94 .. (?)

Something like

spm_dependency(s,  
     url: "https://github.com/gematik/OpenSSL-Swift", 
     requirement: {kind: "upToNextMajorVersion", minimumVersion: "4.2.0"}, 
     products: ["OpenSSL-Swift"] 
   )

If not, feel free to experiment with podfiles in a branch or fork. We can't support/maintain here very much for now though

Hey, yes I tried that already and it didn't help to fix the error. But I will try out some more and give feedback if I figured something out!

@priska96 Have you been able to achieve something regarding the issue?
