+- Make sure to use target `x86_64-apple-ios` instead of `aarch64-apple-ios` here 👆 
+- Try `flutter run` and you might get some path error. So search and replace code containing path `target/aarch64-apple-ios` to `target/x86_64-apple-ios`
+- Now you will run into some errors related to architecture mismatch. To fix this add the following to your Podfile
+
+```diff
+post_install do |installer|
+  installer.pods_project.targets.each do |target|
+    flutter_additional_ios_build_settings(target)
+    target.build_configurations.each do |config|
+      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
++      config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64 i386"
+    end
+  end
+end
+ ```
