While showing arifacts my app crashes abruptedly on:
com.apple.scenekit.scnview-renderer (21): EXC_BAD_ACCESS (code=1, address=0xed0a7ac80)while I run it from Xcode.
No crash is instead produced when running the app by itself.
I tried not inserting or deleting nodes while Scenekit was rendering by means of a lock, but that changed nothing.
I also submitted a ticket to Apple.
Anyone else experiences it and has some solution?
Same here.
Same here. It sometimes works and sometimes crashes.
Using just Scenekit with many own Metal shaders and SCNTechnique and I also get sometimes crashes, which are not related to a special action of the app. But for me it seems to be less stable since I added my own SCNTechnique to support multiple render layers. However, Apple is also using this technique for many effects internally. Seems to come from this direction....
I'm also getting a similar error, a fairly regular crash in Xcode, but fine when not running through Xcode, crashes using a SCNTechnique
