Fundamentals

Layout and Drawing are two different things:

• Layout defines only the positions and sizes of all views on screen.
• Drawing specifies how each view is rendered (how it looks).

# Load the contents of the receipt file
receipt_file = open('./receipt_data.bin', 'rb').read()

# Use asn1crypto's cms definitions to parse the PKCS#7 format
from asn1crypto.cms import ContentInfo
pkcs_container = ContentInfo.load(receipt_file)

# Extract the certificates, signature, and receipt_data

If you work on a Swift project that follows the Model-View-ViewModel (MVVM) architecture or similar, you may want to jump to counterpart in Xcode from your view to your model, and then to your view model. (ie. by using Ctrl+Cmd+Up and Ctrl+Cmd+Down).

You can do this in recent versions of Xcode by setting a configuration default.

From a terminal, just type this command and press Enter:

defaults write com.apple.dt.Xcode IDEAdditionalCounterpartSuffixes -array-add "ViewModel" "View" "Presenter" "Wireframe"
