Steelyard is a utility for generating graphs related to app size evolution.
To install Steelyard using Homebrew, run the following command:
brew install mcrollin/steelyard/steelyard
To install using Mint, run:
mint install mcrollin/Steelyard
Alternatively, you can manually build the tool:
swift build -c release --disable-sandbox --product steelyard
Or run it:
swift run steelyard
To use Steelyard, you’ll need to provide several details that are obtained via Apple’s Developer Portal.
Follow the following steps to create an API key and retrieve the necessary information.
Step 1: Create an API Key
- Go to App Store Connect > Users and Access > Keys > App Store Connect API.
- Click the + button to create a new key.
- Give the key a name, select
Developer(or higher) access role and generate it.
- Download the generated .p8 file.
Note: Store this file in a secure place, as you won’t be able to download it again.
Step 2: Retrieve Key and Issuer IDs
- In the list, find your key, hover over the Key ID and tap on the
Copy Key IDbutton.
- The Issuer ID with a
Copybutton is available right above the list of keys, under the Users and Access section.
Step 3: Locate Private Key Path
The Private Key Path is the location where you’ve stored the downloaded .p8 file.
Step 4: Find Your App ID
The App ID can be found in the App Store Connect > Apps > General > App Information > General Information > Apple ID.
Generate a Graph
To generate a graph, you need to provide several arguments like
app-id. The command format is as follows:
USAGE: steelyard graph <key-id> <issuer-id> <private-key-path> <app-id> [--verbose] [--open-output] [--limit <limit>] [--reference-device-identifier <reference-device-identifier>] ARGUMENTS: <key-id> The key ID from the Apple Developer portal. <issuer-id> The issuer ID from the App Store Connect organization. <private-key-path> The path to the .p8 private key file. <app-id> The App ID. OPTIONS: -v, --verbose Display all information messages. -o, --open-output Open the result graphs. -l, --limit <limit> The number of builds to process, between 0 and 200. (default: 30) --reference-device-identifier <reference-device-identifier> The reference device to highlight in the charts. (default: iPhone12,1) -h, --help Show help information.
