-+# Sets up an isolated Python interpreter, installing required dependencies.
-+#
-+# This function does the following:
-+# 1. Finds a Python interpreter using the best-available built-in cmake
-+#      mechanism do do so. This is referred to as the "host" interpreter.
-+# 2. Creates a Python virtualenv in the cmake binary directory using the
-+#      host Python interpreter found in the previous step.
-+# 3. Locates the Python interpreter in the virtualenv and sets its path in
-+#      the specified OUTVAR variable.
-+# 4. Runs `pip install` to install the specified required dependencies, if any,
-+#      in the virtualenv.
-+#
-+# This function also writes "stamp files" into the virtualenv. These files
-+# are used to determine if the virtualenv is up-to-date from a previous cmake
-+# run or if it needs to be recreated from scratch. It will simply be re-used if
-+# possible.
-+#
-+# If any errors occur (e.g. cannot install one of the given requirements) then a
-+# fatal error is logged, causing the cmake processing to terminate.
-+#
-+# See https://docs.python.org/3/library/venv.html for details about virtualenv.
-+#
-+# Arguments:
-+#   OUTVAR - The name of the variable into which to store the path of the
-+#     Python executable from the virtualenv.
-+#   KEY - A unique key to ensure isolation from other Python virtualenv
-+#     environments created by this function. This value will be incorporated
-+#     into the path of the virtualenv and incorporated into the name of the
-+#     cmake cache variable that stores its path.
-+#   REQUIREMENTS - (Optional) A list of Python packages to install in the
-+#     virtualenv. These will be given as arguments to `pip install`.
-+#
-+# Example:
-+#   include(python_setup)

-+#     KEY ScanStuff

+firebase-cpp-sdk/ios_pod directory
+
+This directory contains a Podfile that allows us to install the Firebase iOS SDK
+via CocoaPods. The Podfile here must include all Cocoapods used by the Firebase
+C++ SDK. The pods are extracted as part of the build process, and the header
+files within them are referenced by the Objective-C++ code in this SDK (see
+setup_pod_headers in CMakeLists.txt for details).
+
+The "swift_headers" subdirectory contains copies of the most recent Swift
+bridging headers for the Firebase iOS libraries that are written in Swift,
+enabling them to be called from this SDK's Objective-C++ code. These headers are
+copied from the most recent firebase-ios-sdk release via this repository's
+update-dependencies.yml GitHub Actions workflow.

 Important: Each version of the Firebase C++ SDK supports a specific version of
 the Firebase iOS SDK. Please ensure that you reference the Cocoapod versions
 listed above.
 
 Note: AdMob C++ is not currently compatible with the latest Firebase AdMob iOS
-CocoaPod (8.x). Please ensure that you use the special version of
-Google-Mobile-Ads-SDK Cocoapod listed above (7.69.0-cppsdk) to maintain
-compatibility with Firebase 8.x.
+CocoaPod (9.x). Please ensure that you use the special version of
+Google-Mobile-Ads-SDK Cocoapod listed above (7.69.0-cppsdk2) to maintain
+compatibility with Firebase 9.x.
+
+Note: Parts of the Firebase iOS SDK are written in Swift. If your application
+does not use any Swift code, you may need to add an empty .swift file to your
+Xcode project to ensure that the Swift runtime is included in your app.
