Unable to build for IOS

[jeancamilo]

Hi guys, i'm getting this error every time I try to build for IOS.

Can anyone help me how to solve? Right now, I'm using mobile_scanner 5.0.0-beta.3, because I know the mlkit was update in beta.3.

The first warning seems unrelated.

However, the second warning indicates that you're unable to build for arm64. Since you have an ARM Mac, can you confirm that you are either testing on an ARM iOS Simulator or an ARM iOS device?

IIRC MLKit does support ARM and we also don't specify its exclusion in the podspec here https://github.com/juliansteenbakker/mobile_scanner/blob/master/ios/mobile_scanner.podspec

The Simulator is excluded, though, as specified on Cocoapods.org: https://github.com/CocoaPods/Specs/blob/master/Specs/b/5/4/MLKitBarcodeScanning/5.0.0/MLKitBarcodeScanning.podspec.json

Just to be sure, you specified building for the ARM64 architecture in your project settings?

Thanks for your response @navaronbracke. I'm trying to embed my application to a native one. So, the time native code try to build using my SDK, it shows me this error and I can't build. I have these lines in my generated podspec: (maybe add "excluded archs arm64" works?)

  s.ios.deployment_target = '12.0'
  s.swift_version = '5.0'
  s.static_framework = true
  s.user_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386' }
  s.pod_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386' }

Build my Flutter application with mobile_scanner works well, but in this case, building my sdk in a native code, don't. I tried to build from an intel mac but I don't have success too.

Update: I added those configs to my podspec:

  s.user_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386 arm64 armv7' }
  s.pod_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386 arm64 armv7' }

And the error changed a little, but it persists :(
