07/05/2026

Description:

Apple's Human Interface Guidelines are very specific about the formatting of the "Sign in with Apple" button. The logo used by the Croissant app goes against Apple's regulations.

Here's a screenshot of how it looks inside of the Croissant app:

The following problems exist with how the Apple logo and the "Sign Up with Apple" button is displayed by the Croissant app for iOS.

• The logo is outlined. Apple's Human Interface Guidelines state that you must use the official, unaltered and solid logo. 
• Font. The guidelines require a specific font which is not used here.
• The button. Apple's guidelines require solid black, solid white or white with a thin gray outline. 

Steps to Reproduce:

1. Download and launch the Croissant app for iOS (version 3.0.2)

2. Select the "Create Account" option 

3. View the "Sign Up with Apple" button 

Result: the "Sign Up with Apple" button used by the Croissant app for iOS goes against Apple's Human Interface Guidelines 

Expected: the "Sign Up with Apple" button used by the Croissant app for iOS should be in compliance with Apple's Human Interface Guidelines
