Hi @Polaris00418,

Below is a copy of the answer I gave you on this question: viromedia/viro#87 (comment)

It looks like you're trying to build your app for the iOS Simulator (x86_64), we don't support the iOS Simulator, so you'll need to run it on an actual iOS device (iPhone/iPad).

I downloaded your project and was able to run it on my iPhone 6S, except I had to change 1 setting in the project file, I had to set "Enable Bitcode" to "No", see the screenshot below for my project setup:

Let me know if that works for you!

i set enable bitcode "no" at that time.. and of course i am using iphone x

Hi @Polaris00418,

Make sure that your device is selected in the top left hand corner of Xcode:

Let me know if that doesn't work

Hi @Polaris00418,

If you go into ViroSampleAR/ios make sure that you have run pod install and then ensure that you're opening the ViroSampleAR.xcworkspace not the ViroSampleAR.xcodeproj directory.

Thanks

Does this mean we can not run the app in the simulator anymore? We have an otherwise 2D app, that has an optional AR module. We definitely would like to test the non-AR related parts of the app with the simulator. Is that possible?

Hi @itchingpixels,

Yes, this is a limitation with our framework right now in that it is not compiled for x86 (Intel/AMD chipsets).

You can try the suggestions listed here:

https://stackoverflow.com/questions/31574430/optional-framework-not-working-coreaudiokit-not-on-simulator

Essentially using preprocessor macros to "hide" any references to Viro when compiling for the iOS Simulator. You may also need to change how you link against our framework(s).

We ourselves haven't tested this method yet, but do let us know if you do run into issues with it. We'll look into adding, at the very least, compiling support for the iOS simulator, if not full support.

Thanks,

Thank you, we'll give it a go!

Hi @itchingpixels ,

It looks like another one of our users were able to build their app for simulator by making our framework optional.

Feel free to follow the instructions there and let us know if you run into any issues.

Thanks,
