As stated in Mac Focussed? 🍏, we are focussing at least 50% of our dev/testing efforts on iPhone because that's where vast majority of people that pay for Apps are. 🎫 Obviously we will still devote the 40% to Android and we want the UI/UX to be seamless on as many devices as possible. But if we want our App & company to be sustainable, this iOS is where we need to focus. 🎯

Official docs look like a good starting point: https://docs.flutter.dev/deployment/ios 📜 And this looks decent too: https://medium.com/front-end-weekly/how-to-test-your-flutter-ios-app-on-your-ios-device-75924bfd75a8

Had to enable Settings → Privacy & Security → "Developer Mode" on my (personal) iPhone to get this working.

And ... the iOS device (iPhone) must be on the same Apple (iTunes) account ... 🙄 In my case my iPhone is not on the same account as my Mac ... so I will need to ... 💭 Oh hold on, I do have an iPhone 6S I can use that is connected to my the same Apple Account as my Mac!! 🎉 BRB!

While I wait for my iPhone 6S (ancient but still working) device to update to iOS 15, Tried following the instructions in the SO answer:

rm ios/Podfile.lock
flutter run

Got the following error:

You can connect to your Apple Developer account by signing in with your Apple ID
in Xcode and create an iOS Development Certificate as well as a Provisioning
Profile for your project by:
  1- Open the Flutter project's Xcode target with
       open ios/Runner.xcworkspace
  2- Select the 'Runner' project in the navigator then the 'Runner' target
     in the project settings
  3- Make sure a 'Development Team' is selected under Signing & Capabilities > Team.
     You may need to:
         - Log in with your Apple ID in Xcode first
         - Ensure you have a valid unique Bundle ID
         - Register your device with your Apple Developer Account
         - Let Xcode automatically provision a profile for your app
  4- Build or run your project again

After a bit of digging, I've discovered that because I've got iOS 16.2 in my XCode and iPhone 6S only goes up to iOS 15, I cannot use it as a device for testing ... 😢

So I'm not going to be use this device for testing. 👎 Gonna need to retrieve the iPhone 8 from the Studio @home on Monday. ⏳

libffi is keg-only, which means it was not symlinked into /opt/homebrew,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

For compilers to find libffi you may need to set:
  export LDFLAGS="-L/opt/homebrew/opt/libffi/lib"
  export CPPFLAGS="-I/opt/homebrew/opt/libffi/include"
