You can run the example app from Android Studio by
pressing the run (▶) button.

Step 2c: Add iOS platform code (.swift/.h+.m)

We recommend you edit the iOS code using Xcode.

Before editing the iOS platform code in Xcode,
first make sure that the code has been built at least once
(in other words, run the example app from your IDE/editor,
or in a terminal execute
cd hello/example; flutter build ios --no-codesign).

Then use the following steps:

Launch Xcode.

Select File > Open, and select the
hello/example/ios/Runner.xcworkspace file.

The iOS platform code for your plugin is located in
Pods/Development Pods/hello/../../example/ios/.symlinks/plugins/hello/ios/Classes
in the Project Navigator.

You can run the example app by pressing the run (▶) button.
