Wrong fonts loaded from Storyboards in Xcode 15

We use Storyboards and custom fonts in our app. Once we started developing new features for iOS 17 and did the first build in Xcode 15, we've noticed that in quite a few places incorrect fonts are set to views. In some places it is incorrect weight, while in other it's completely different font.

Some observations:

  • Fonts may change the next time app is build. E.g., instead of SF Pro Display Semibold we got SF Pro Display Heavy, and then after few relaunches it switched to Nunito Bold 😵‍💫
  • We’ve ensured that correct font is set in Storyboard, and even tried to re-assign it. That didn’t help.
  • All custom fonts are properly added to a target and are registered in info.plist
  • All custom fonts are listed in UIFont.familyNames, so they are indeed registered with the system.
  • Wrong fonts are loaded on both development environment and in TestFlight builds
  • We’ve never experienced anything similar before Xcode 15

What we've tried:

  • Re-assigning fonts in Storyboard.
  • Creating new Storyboard in Xcode 15 and copying screens into it.

I wonder if anybody else having similar issues and maybe knows the workaround.

Thank you.

P.S. I've filed a Feedback to Apple: FB12903371

The issue seems to be fixed in Xcode 15.1 Beta 1! Fonts in my test project are loaded correctly now. 🥳 Too bad, we are already setting all fonts from the code 😅

Here is how it looks in Xcode 15.0

I have the same issue as well since the first beta until now. for some of the screen, we assign the font in the code instead of storyboards and it works but we can't do it for all screens since our project is too big and assign all fonts will be huge effort

I'm having the same issue. For my iPad app, one screen switched all labels to bold. In another screen, my iPhone app has switched the labels for one section of my tableview to bold. I printed out the font in the console and even though my storyboard is set to Roboto-Thin, it's printing Nunito-Bold.

We are seeing the same behaviour. Fonts are all messed up in xcode 15 beta 6

We have same issue, fonts are changed from regular to medium or from bold to regular etc. No real logic here why and on what view...

I have the same issue. For me, issue was solving by adding custom fonts programmatically. But the thing is I have to add custom fonts by code wherever I have added custom fonts in storyboard.

Same issue here, any movement here? I have seen this cause some major strange behavior in our app.

Same issue here. Only solution we found, is to set custom font programmatically.

Yes, we ended up doing the same... 😵‍💫

We ended up assigning all the fonts from the code...

We're suffering from the same problem.

Hello, I have the same problem, also yesterday with the latest version of Xcode RC, I thought this problem would be solved, but it was not. Our project is too big. I hope that for the latest version the problem will be solved.

It's a known issue in the Xcode 15 release notes: https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes

Interface Builder documents using custom App fonts may load incorrect font at runtime. (113624207) (FB12903371) Workaround: Set font manually in code.

Same issue, it helps to open xib or storyboard, set font to some other and then assign the one u need. After such reassigning it starts to work correctly again. But its weird and I hope it will be fixed asap...

I would recommend to follow the below steps, which will make things easier and quick

  • Delete custom fonts from your project. || *Backup fonts
  • Run the app to the simulator or a real device
  • Now re-add your custom fonts to your project
  • Run it again

Good luck! 🥳

Any updates on this? Held off on updating to Xcode 15 for our company's project to ensure things were more stable. We have a very large project with thousands of labels. Changing all of these to be programmatically set will be a huge effort. Now having to downgrade to Xcode 14 until this is resolved.
