[!] Oh no, an error occurred.

[alexgrusu]

If I execute fluttter run in my project

I can see the following output.

Already run arch -x86_64 sudo gem install ffi and the output is the same.

Error output from CocoaPods:
↳

[!] Automatically assigning platform `iOS` with version `12.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See
`https://guides.cocoapods.org/syntax/podfile.html#platform`.

Error: To set up CocoaPods for ARM macOS, run:
arch -x86_64 sudo gem install ffi

Error running pod install
Error launching application on iPhone 12.

Finally, found a solution.

Somehow, If I went to the iOS folder of my flutter project and type 'pod init; pod install' a basic Podfile was generated (meaning that it had specified only the platform).

I found a post somewhere that suggested to delete everything in the iOS folder about pod and to run flutter run in the project. Running 'flutter run' in the project folder (that integrates 'pod install' as well), generated a much detailed Podfile, but this time I faced another error in regards with the platform (listed below).

Error output from CocoaPods:
↳

    [!] Automatically assigning platform `iOS` with version `12.0` on target
    `Runner` because no platform was specified. Please specify a platform for
    this target in your Podfile. See
    `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Error: To set up CocoaPods for ARM macOS, run:
  arch -x86_64 sudo gem install ffi
I tried to follow the suggestion to run the command shown above, but the same error occurred.

Then, I found an answer here https://stackoverflow.com/questions/64901180/running-cocoapods-on-apple-silicon-m1/64901980 that is similar with the official documentation https://github.com/flutter/flutter/wiki/Developing-with-Flutter-on-Apple-Silicon.

Even so, the answer from the stack overflow didn't work straight forward for me until I followed these steps:

1. Open finder -> Utilities
2. Right click on the Terminal -> Get Info
3. Check 'Open with Rosetta'
4. Open a new terminal and type 'gem uninstall cocoapods'
5. sudo gem install cocoapods
6. gem uninstall ffi
7. arch -x86_64 sudo gem install ffi

I hope this is useful for someone else.

Thanks @alexgrusu this helped. This was related to the newer m1 chip and I faced it in React Native project.
