Hey guys! We’re trying to fix up an old fuse app to work with Fuse-X Studio Beta 4.  
On Windows / Android its working well but no love on Mac, so that means no IOS…When trying to build on OSX, we’re stuck with this error: (Have installed [Mono 6.12.0 (Stable channel)])

`You are using dlopen without a full path, retrying by prepending /usr/lib`  
`Generating code and data 6.62 s ⠏Could not find PresentationCore referenced by assembly QRCoder, Version=1.3.9.0, Culture=neutral, PublicKeyToken=null.`  
`Could not find PresentationCore referenced by assembly fuse-studio, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null.`  
`Could not find PresentationCore referenced by assembly Outracks.Fuse.Command, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null.`  
`Could not find PresentationCore referenced by assembly fuse, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null.`  
`Generating code and data 6.67 s`  
`FATAL ERROR: Could not load the file 'PresentationCore'. (pass --trace for stack trace)`

Anyone have any idea? We really need to get this working but dont know whats wrong.  
Fuse 1.9 does not have the same issue! Have the exact same issue on 2 different Mac’s…  
Thanks

I guest it’s still has a bug in fuse-x studio beta when generating Xcode Preview project, but you can build fuse project by using the uno command in your project directory: `uno build ios -c Release`.

The output will be in the `build` folder

THANK YOU! 😃  
This made it possible to open the project in Xcode!!

Initially, we got the error:  
`Signing for "Test" requires a development team. Select a development team in the project editor. Code signing is required for product type 'Application' in SDK 'iOS 10.0'`

But after some searching it seems we can do:  
`uno build ios -c Release -adebug`  
to skip the error and sign it in XCode… Is it supposed to work like that?

Anyway, when doing this we were able to build for iOS! 🙂
