How to resolve error of "errSecInternalComponent" while building archive for appstore?

Question

I am trying to submit flutter app to Appstore. Here are the steps I followed:

Deleted all certificates and provisioning profiles

Create/Add IOS Distribution Certificate

Create IOS Provisioning Profile

Add IOS Provisioning Profile

Clean App

Build Then Run App

Set Codesigning and Provisioning Profile In Build Settings

Lots of Googling > to no successes

Basically, facing the error of "errSecInternalComponent"

Here is the error I get:

 Warning: unable to build chain to self-signed root for signer "iPhone Distribution: Johnny  (**********)"
    /Users/johnny/Downloads/chat_app-master 2/build/ios/Release-iphoneos/Runner.app/Frameworks/App.framework/App: errSecInternalComponent

Solution 1

You are having an issue with a certificate, that's why you get this warning. You need to generate a new one.

Try this: xcode -> preferences -> accounts -> select the account -> manage certificate -> click on the (+) icon in the bottom left side of the popup window -> ios development

Solution 2

Build the first time with Xcode, Xcode will ask you to update the keychain, click on always allow. After that, your command line build will work.

it doesn't give option for iOS development , it gives option for Apple Development, how should I proceed?

Add Apple Development should work as well. Make sure on the iOS device you go to the General -> Device Management -> and click your account ...
