Issue

Building and debugging work correctly, but TestFlight uploads fail with “Asset validation failed” due to frameworks containing bitcode.

​
Cause

Apple deprecated bitcode in Xcode 16. Some DARO SDK dependencies still contain bitcode and must be removed manually until vendors update their frameworks.

​
Solution

Add this code to the bottom of your Podfile, then rebuild and deploy. This removes bitcode using bitcode_strip during the build process. 
post_install do |installer|

  installer.pods_project.targets.each do |target|

    if target.name == 'OpenWrapSDK'
      `xcrun -sdk iphoneos bitcode_strip -r Pods/OpenWrapSDK/OpenWrapSDK/OMSDK_Pubmatic.xcframework/ios-arm64/OMSDK_Pubmatic.framework/OMSDK_Pubmatic -o Pods/OpenWrapSDK/OpenWrapSDK/OMSDK_Pubmatic.xcframework/ios-arm64/OMSDK_Pubmatic.framework/OMSDK_Pubmatic`
    end

    if target.name == 'HyBid'
      `xcrun -sdk iphoneos bitcode_strip -r Pods/HyBid/PubnativeLite/PubnativeLite/OMSDK-1.4.10/OMSDK_Pubnativenet.xcframework/ios-arm64/OMSDK_Pubnativenet.framework/OMSDK_Pubnativenet -o Pods/HyBid/PubnativeLite/PubnativeLite/OMSDK-1.4.10/OMSDK_Pubnativenet.xcframework/ios-arm64/OMSDK_Pubnativenet.framework/OMSDK_Pubnativenet`
