Ios swift – Flutter Xcode 15 BIG Problem – 'Flutter/Flutter.h' file not found & SDK does not contain 'libarclite' at the path

Everything started with the message ‘You can not upload your app with Current Xcode’ while validating and distributing the app from Xcode.

https://developer.apple.com/news/upcoming-requirements/?id=04292024a

The unfortunate part is that I tried on the 29th; if I had tried a day earlier, I wouldn’t have had to deal with this…

I updated Xcode to 15 (which also required updating my MacOS to Sonoma – we made two changes at the same time, as you can understand), and I’ve tried every solution imaginable for the past 3 days. I can’t remember ever struggling this much with a problem before. I’ve tried over 20 solutions, and consistently, I’m getting errors like:

‘SDK does not contain ‘libarclite’ at the path’

or

Lexical or Preprocessor Issue (Xcode): ‘Flutter/Flutter.h’ file not found(LAST ERROR)

Podfile:(Final, I changed it more than 10 times, always encountered with a problem)

  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

    target.build_configurations.each do |config|

    end
  end
end

How can I solve my problem?

It seems like developing iOS apps with Flutter using Xcode 15 might become a thing of the past.
