If you need to quickly open an app’s document directory on the iOS Simulator, you can quickly get the path from the xcrun CLI.
xcrun simctl get_app_container booted ${bundle_id} data
Here’s some ruby you can throw into a Rakefile of your iOS app 😉
# Rakefile
desc "Open the simulator document directory"
task :docs do
bundle_id = File.read("MyAppName/MyAppName.xcodeproj/project.pbxproj")
.scan(/PRODUCT_BUNDLE_IDENTIFIER = "(.*)"/)
.flatten.first
app_directory = `xcrun simctl get_app_container booted #{bundle_id} data`
puts "Opening simulator directory: #{app_directory}"
`open #{app_directory}`
end
