Mac get stalled when building in Xcode

I have an issue with Xcode. When I do a build and run the Mac got stalled and I must force restart it by holding the power button. I found out that it may be related with storyboard with many view controllers (7-8). If decrease the number of view controllers in the storyboard the issue disappears. I have a powerful MacBook Pro 15 mid 2014 that is very fast with all the programs I run. What’s the problem here? Is that a bug?

I checked on the web and I found out that the issue is probably related with SCNView and ARSCNView. Indeed, I’ve got this issue just with 2 projects and both make a large use of those views. I have other projects with many view controllers but without SceneKit or ARKit and those worked fine. The solution seems to be to remove all the SCNView/ARSCNView from the storyboard and create it by code. I didn’t try it yet, I’ll let you know if it will work. Anyway I have the last version of Xcode and macOS. 16 GB or RAM.

8 view controllers is nothing.


But maybe you have a problem with one of the view controllers.


Which version of OS, of XCode ?

How much RAM ?

Yes it was that way! Programmatically creating the SCNView solved the issue. Apple should solve this "bug" with storyboard.
