Undefined symbol after cocoapod import

[Warpzit]

After trying to implement library with cocoapods to an existing project I get following errors:

Ye this was meant for the general library and not the samples ;)

[sheepmaster]

This does seem like an issue in the SDK that should be addressed :)

[sheepmaster]

Can you share your Podfile and Podfile.lock? Did you add any other pods?

[Warpzit]

Okay so I can't recreate it but I'm going to give a complete list of what i tried yesterday:

• Removed all other pod import untill I only had following:
  pod 'Alamofire', '~> 5.0.0-rc.2'
  pod 'Firebase/Crashlytics'
  pod 'GoogleMLKit/TextRecognition'
• Ran pod update
• Nuked old pods and ran pod install/update again
• Updated imports from old firebase mlkit library to import MLKit
• Cleaned project
• Rebuild project
• Restarted XCode
• Removed derrived data
• Build project against different targets
• Updated build settings to work with different valid architectures
• Everything above in different orders

What might have worked.

• Restarting my mac and trying again from scratch

[sheepmaster]

For posterity: the missing symbols are from GTMSessionFetcher, which is a dependency of the MLKitCommon pod.

Experimenting with the same issue when trying to run my app with all of the Google MLKit pod installed in SwiftUI emulator. I don't understand your solution. Maybe the solution is to exclude this from emulator builds? How can achieve it?
