Xamarin Error HE0003 - Could not load the framework 'IBFoundation'

Question

After updating the XCode to 13 and the macOS to 11.6, when I try to deploy the Xamarin iOS app to the physical device,
the error HE0003 - Could not load the framework 'IBFoundation' is shown.

I took a look into the XCode application folder, indeed it does not contain the IBFoundation file.
(path: /Applications/Xcode.app/Contents/Frameworks/IBFoundation.framework/IBFoundation)

I did launch the XCode to install the components required.

Below is the system info

Hello,
Welcome to our Microsoft Q&A platform!
XCode13 is not yet supported in Xamarin.iOS, you could try to downgrade Xcode (open this link, sign in with your apple developer account, select Xcode to download and install).
There are also 2 options for you If you need to keep Xcode 13, for more information you can refer to
https://github.com/xamarin/xamarin-macios/issues/12778

Best Regards,
Wenyan Zhang

Answer 2

As others have already referred to the link https://github.com/xamarin/xamarin-macios/issues/12778

I have downloaded and installed the Xamarin.ios-15.0.0.6.pkg and now everything works fine finally.
The simulators are showing up again and there is no problem deploying the app on the physical devices (iOS15 and <iOS15 both work fine).

It is believed that this version will be released very soon as mentioned in the thread. Therefore if it is not urgent, you can wait for the Visual Studio updates. Or if it is urgent, download the above package from the link and install it manually.

Thanks for all the input. It is greatly appreciated.

Answer 3

Looks like Xcode 13 changed the Interface Builder (IB), I'm not sure why deploying the solution is hanging on this, IB shouldn't be required just to connect the debugger (esp if Hot Restart is not required)

Downgrading to Xcode 12.5 would like restore the IBFoundation.framework in the location VS is looking for, but that's not an option in my case

Answer 4

I had same problem today ; i downgrade Xcode13 to Xcode 12.5.1 No simulator but it works with physical devices

for downgrade : https://developer.apple.com/download/all/?q=for%20Xcode%2012

Answer 5

The second solution published here https://github.com/xamarin/xamarin-macios/issues/12778 worked for me on VS 8.10.9, Xcode 13 and iOS 15. I only installed xamarin.ios-14.20.0.27.pkg package.
