Script to generate typography constants

GenerateFontConstants

Script, written in Swift 2.0, which generates a constants file to enable compile time checking and a more Swift way of defining typography rules across your app.

Also available: Localization

What it does

👍 Define typography rules to keep consistency across your app.
👏 Uses IBDesignable.
✊ Allows compile time checking of your font styles.
🙏 More Swifty syntax. Typography.Title.font instead of UIFont(name: "Helvetica-Bold", size: 48).
💪 Automatically style a label using the .style(...) method.

What it doesn't do

❌ Kerning and linespacing - yet!

Usage

Retrieves a UIFont for a specific style.
titleLabel.font = Typography.Title.font

Sets a UIFont on a label for the specific style.
Typography.Title.style(label: titleLabel)

Installation

• Add a run script in 'Build Phases' to the target that executes the script below.
• Add the Typography.plist to the input files section of the build phase script.
• Add the Templates/TypographyTemplate.swift to the input files section of the build phase script.
• Add Typography.swift to the output file location for where your constants will be generated.
• Build your project.

Build Script

SCRIPT_FILE="${SRCROOT}/Scripts/Generate-Swift-Font-Constants.swift"
echo "Running a custom build phase script: $SCRIPT_FILE"

${SCRIPT_FILE} "${SCRIPT_INPUT_FILE_0}" "${SCRIPT_INPUT_FILE_1}" "${SCRIPT_OUTPUT_FILE_0}"
echo "End of script"

scriptExitStatus=$?
echo "DONE with script: ${SCRIPT_FILE} (exitStatus=${scriptExitStatus})\n\n"
exit "${scriptExitStatus}"
