Analytics Processor

The App Store Connect user interface and exported CSV documents are not straightforward in regards to knowing which major iOS versions users are on. This quickly hacked together parser processes a CSV export and renders it as Markdown.

Warning: Currently this assumes you use App Store Analytics in German. Support for other languages still is an open issue.

How To Get Report

1. Go to App Store Connect.
2. Go to Analytics.
3. Select Metrics.
4. Select active devices.
5. Select by platform version.
6. Select grouping by months above the graph.
7. Export the CSV document from within the ellipsis menu.
8. Provide the report file as an argument.

Build

To build a binary, navigate into the package directory and run:

$ swift build

Usage

Then you can run the built binary like this:

$ swift run AnalyticsProcessor <input file>

Development

It is convenient to define an argument in the generated Xcode scheme which specifies the absolute path to an input file for debugging.

Example Output

The rendered markdown currently looks somewhat like this:
