Cannot build iOS with version `^0.1.0`

[thomaaam]

Hey, your package works beautifully on Android. However on iOS I am still unsuccessful to build with the latest version. Note that when I build with version ^0.0.4 it builds successfully.

Here's what happens when I try to build ^0.1.0:

[!] The 'Pods-Runner' target has transitive dependencies that include statically linked binaries: (GoogleDataTransport, GoogleDataTransportCCTSupport, and GoogleUtilitiesComponents)

I did google this issue and found this trick:

pre_install do |installer|
  # workaround for https://github.com/CocoaPods/CocoaPods/issues/3289
  Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
end

However further down the road I then ran into these issues:

Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_MLKTextLine", referenced from:
      objc-class-ref in ScanProcessor.o
  "_OBJC_CLASS_$_MLKTextBlock", referenced from:

  "_OBJC_CLASS_$_MLKTextRecognizer", referenced from:
      objc-class-ref in CameraViewController.o
  "_OBJC_CLASS_$_MLKVisionImage", referenced from:
      objc-class-ref in CameraViewController.o

What is curious here is that when I use ^0.1.0 over ^0.0.4 most the Firebase and Google pods are downgraded. Therefore I wonder if you use outdated Firebase/Google pods for version ^0.1.0?

This is some changes to my Podfile.lock after upgrading to ^0.1.0:

Note how most or all pods are downgraded?

Not sure how to proceed from this, but I still cannot use card-scanner-flutter for iOS until there is a resolution to this issue. It's the only viable card scanner for Flutter as far as I can find, so I hope you have some answers!

Hey. Can you just try commenting out use_frameworks! line from ios/Podfile under your Flutter project? And run once.

[thomaaam]

It appears to work as pod install succeeds, but then flutter build ios fails due to this error:

fatal error: 'qr_code_scanner/qr_code_scanner-Swift.h' file not found

It appears this pod is installed successfully with use_frameworks!. Also most of my pods are downgraded again as a result of commenting out use_frameworks!

[nateshmbhat]

is this issue fixed ? can we close this @thomaaam @m-zaink ?

[m-zaink]

Let me look into it more closely then. @thomaaam

Thanks for bringing out this issue.

@nateshmbhat do not close this issue yet. I'll pick up by the weekend and fix it.

[thomaaam]

Did you learn anything during the weekend, @m-zaink? 😄 Just tell me if you need something more from me. We are very eager to get this out on iOS, as we currently only support it on Android.

[thomaaam]

I am able to get this working on iOS now with this pubspec.yaml configuration:

card_scanner:
  git:
    url: https://github.com/DeadBryam/card-scanner-flutter
    ref: fix-static-framework

Thanks to this fix: #17

PS: Though I tested on an iPhone SE (1st generation), so the layout does not look perfect, but at least it works! This might even be a cosmetic issue that applies to the latest release as well.

When trying to build for production I yet again faced some issues. Thus what I said over here ☝️ does not do the trick after all 😞

Undefined symbols for architecture armv7:
      "_OBJC_CLASS_$_MLKTextLine", referenced from:
          objc-class-ref in card_scanner(ScanProcessor.o)

      "_OBJC_CLASS_$_MLKVisionImage", referenced from:
          objc-class-ref in card_scanner(CameraViewController.o)

17 is not yet a full worthy fix.

The reason is that MLKit does not support 32bit architectures anymore See here: https://developers.google.com/ml-kit/migration/ios

ML Kit does not support 32-bit architectures (i386 and armv7). ML Kit does support 64-bit architectures (x86_64 and arm64).

I have used this configuration on my iPhone XS and the layout could be better. And no recognition at all. I can only see the camera but nothing is recognized

We are also using version - ^0.2.0+3 and facing same issue, is there any solution for this ? If so, please let us know. [!] The 'Pods-Runner' target has transitive dependencies that include statically linked binaries: (GoogleUtilitiesComponents)
