Updating Xcode and macOS can sometimes lead to unexpected issues, especially when it comes to custom fonts.

In this article, we'll explore the possible causes and solutions to get your custom fonts working again.

Understanding the Issue

Custom Fonts and Attributed Text

Custom fonts are a crucial aspect of any iOS or macOS app, allowing developers to create a unique and visually appealing user experience. Attributed text, on the other hand, is a feature that enables developers to style text with different fonts, colors, and other attributes. When custom fonts are not showing up in attributed text, it can be frustrating and time-consuming to troubleshoot.

Possible Causes

There are several reasons why custom fonts might not be working after updating Xcode 16 and macOS 15.0.1. Some possible causes include:

Font file issues: The font file itself might be corrupted or not properly formatted, leading to display issues.
Font naming conflicts: If you have multiple font files with the same name, it can cause conflicts and prevent the font from displaying correctly.
Xcode project settings: Xcode project settings might not be configured correctly, leading to font display issues.
macOS font cache issues: The macOS font cache might be outdated or corrupted, causing font display issues.

Troubleshooting Steps

Step 1: Verify Font File Integrity

The first step in troubleshooting custom font issues is to verify the integrity of the font file. Make sure the font file is:

Correctly formatted: The font file should be in a valid format, such as TrueType or OpenType.
Not corrupted: The font file should not be corrupted or damaged in any way.
Properly named: The font file should have a unique and descriptive name.

Step 2: Check Font Naming Conflicts

If you have multiple font files with the same name, it can cause conflicts and prevent the font from displaying correctly. To check for font naming conflicts:

List all font files: List all font files in your project to identify any potential conflicts.
Rename conflicting fonts: Rename any conflicting font files to a unique name.

Step 3: Review Xcode Project Settings

Xcode project settings might not be configured correctly, leading to font display issues. To review Xcode project settings:

Check font settings: Check the font settings in your Xcode project to ensure they are correctly configured.
Verify font usage: Verify that the font is being used correctly in your app.

Step 4: Clear macOS Font Cache

The macOS font cache might be outdated or corrupted, causing font display issues. To clear the macOS font cache:

Clear font cache: Clear the font cache on your macOS system.
Restart Xcode: Restart Xcode to ensure the font cache is updated.
