System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

- Copy the delivered ipa into a directory to work in. 

- export PlistBuddy="/usr/libexec/PlistBuddy" to get the PlistBuddy tool to your shell. If it is not added, all references to PlistBuddy
  will need to be written as the full path. 

- Take the delivered App.ipa and unzip it using the unzip command. This should produce a Payload directory containing the app and its 
  resources. 

- Enter the command "codesign -d --entitlements :enterprise.plist Payload/PathToApp.app/" This pulls the entitlements out of the app, and 
  prints them to a plist, without a leading "blob" of data. Pay particular attention to the colon before the enterprise.plist file name.
