🎛️ Generic ID Format

Format any ID using a custom pattern with 'X' as placeholders.

print("123456789".genericFormat(format: "XXX-XXX-XXX"));       // 123-456-789
print("T123456789".genericFormat(format: "X-XXX-XXX-XXX"));    // T-123-456-789
print("123456789".genericFormat(format: "XXX XXX XXX"));       // 123 456 789

Use this when you need flexibility to support custom ID formats.
