same error

Same error but build runs perfectly on ios 17 beta 3

Its strange that no one has posted solution to this problem! Its occuring in iOS 16.5.1 as well Xcode 15 Beta. App works fine in old iOS and also in iOS 17 on simulator but doesn't work in iOS 16.5.1.

Just upgraded iOS to 16.6 now and still no luck. Same error!

I'm getting this same bug on iOS when I include the amplify_api package since it pulls in the connectivity_plus package.

Same error

I'm getting this same bug on iOS when I include the amplify_api package since it pulls in the connectivity_plus package.

Ok, just got to the temporary solution for this, i'll post the things i did to avoid this error.

Changed build Targets in pod and runner to 12.0
In Xcode, Runner -> Edit Scheme -> Removed all debug and diagnostics extras that could overload the memory i.e. In options i unchecked
Debug XPC services used by app
Enable user interface debugging
Enable backtrace recroding
Made sure that nothing is selected in diagnostics as well.
While xcode 15.3 is installed, i have xcode 14.3.1 side by side as well, executed applitication on xcode 14.3.1 and it ran without any issue.
I am not saying that it'll resolve the issue for you but it did for me. I am able to run app without any issue now

[assemblethis]

Thanks @madilsharief, you figured it out. The issue is XCode 15 beta 4. It works fine with XCode 14.3.1. That's all I changed and it worked right away:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

But heading out for vacation so I don't have time to get a minimal POC over to the XCode team to fix this!

[corey-sobel]

Are there any updates on this?

I'm still able to reproduce in Xcode 15 beta 7 (released August 22nd) when running on iOS devices that are on OS version 16.6. Confirmed the issue is due to the connectivity_plus dependency and still reproduces on the latest version of connectivity_plus (4.0.2)

Haven't tested on flutter myself, but this looks like a problem related to XCode 15 removing support for iOS < 12.
So a simple post_install script on the Podfile solved the issue for me. I'll post it here so maybe it can help someone else too:

post_install do |installer|
 installer.pods_project.targets.each do |target|
     target.build_configurations.each do |config|
        if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < 12.0
          config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
        end
     end
 end
end
