We discovered a problem: a wasm file is neither an executable nor a bundle, so it cannot be code-signed. Since our App needs to pass notarization, we have not set the com.apple.security.cs.allow-unsigned-executable-memory entitlement. Without setting com.apple.security.cs.allow-unsigned-executable-memory, loading a wasm module results in an “unsigned code” error that causes the process to cras...

I would be ok for now with the local option, but XCode 16.4 doesn't show the option "build to run locally" (SIP is disabled). When using "Automatically manage signing" it ends in a "Please file a bug report".

Sincerely, Anis Fri, 24 Oct 2025 11:04:25 GMT cloudleadanis https://developer.apple.com/forums/thread/804811 Hello, my iOS apps are exiting right after launch on a few of our iOS devices. I tried a couple of my apps that are deployed to our fleet and they do the same thing. If I run the app(s) in the Simulator it works fine and if I run the app(s) on the offending devices it works fine as well. Once I stop the run in Xcode the app on the device will not launch. I'm thinking something is missing like a certificate etc. Just not sure. Any ideas on how to troubleshoot this? I would really like to get this fixed.
