I have an iOS app that I want to run on my device via Xcode and the USB-C cable. Once I run it through Xcode with my device as the target the app builds on device. But then I get an error message stating I need to Verify App via the Settings section "VPN & Device Management" I click on my account under "Developer App" and I trust my developer account. Then I am asked to "Verify App" And when I do so I can a spinning icon that spins for a minute. Spinning Icon stops and I still cant use the app. I have tried a couple of different things in particular Here is the Xcode error output : Domain: IDELaunchCoreDevice Code: 0 Recovery Suggestion: Verify that the Developer App certificate for your account is trusted on your device. Open Settings on the device and navigate to General -> VPN & Device Management, then select your Developer App certificate to trust it.

I have been working on a project before this year's new OSX and Xcode update and I was able to build the project with little trouble. But since updating to any of the beta software, including the latest version of Tahoe 26.0 and Xcode26-beta4 I have not been able to build this same project. I have tried reseting package cache and updating to the latest package versions. As well I have deleted the derived data and cleaning the build folder. The following error output is one of 55 errors I am getting. It seems like the modules for the XRSimulator are redefinitions from those for MacOSX. I don't know how to limit or redirect the definition of the modules to just those for the XRSimulator (this is a VisionOS project). I also tried all of this on different betas of Xcode with all the same result. This bug is causing a problem with the 16.4 version of Xcode as well. I would really really appreciate anybody's help on this. in file included from /Applications/Xcode.app/Contents/Developer/Platforms/XRSimulator.platform/Developer/SDKs/XRSimulator26.0.sdk/usr/include/module.modulemap:2: Previously defined here : CommandLineTools/SDKs/MacOSX26.0.sdk/usr/include/AppleTextureEncoder.modulemap
