This is the latest error code. missing input '/Users/gene/Library/Developer/Xcode/DerivedData/volk-neon-asm-fmqioscvzlcgqjferhnlcfrdltsi/Build/Intermediates.noindex/volk-neon-asm.build/Debug-maccatalyst/volk-neon-asm.build/Objects-normal/x86_64/volk_16i_max_star_horizontal_16i' and no rule to build it I see that the URL include "Debug-maccatalyst" when it should be "Debug-iphoneos". Also, there is a "Debug-iphoneos" directory with content. The problem is that adding assembly files to a project is not getting them copied into the "Objects-normal/arm64" directory. If I copy a source file manually and then use Xcode to assemble it, it works.

The latest behavior is that all assembly files are not found when I use "Product>Perform Action.Assemble ..."

When I do that, it sets up a pair of swift files. I have C code that I want to use which currently compiles and runs on the command line in macOS. I am trying to get this "function" to run in iPadOS. I have destinations, etc set up for iOS and it compiles the code for iOS but does not wrap it up as an app. I have seen C++ used in an app target. Do you have any suggestions for how to include the code into an app for iOS?

I have a followup question. When I add my iPad Air gen 5 as a potential destination, I get the error message "Ad Hoc signing is not allowed with SDK iOS 17". When I replace "Sign to Run Locally" with iOS development, I get the following Xcode error: "Showing Recent Messages /Users/gene/Desktop/DriverKitExsample_Unsigned/CommunicatingBetweenADriverKitExtensionAndAClientApp/DriverKitUserClientSample/DriverKitUserClientSample.xcodeproj: Provisioning profile "iOS Team Provisioning Profile: *" doesn't include the com.apple.developer.driverkit.userclient-access entitlement." Xcode pops up a bow saying to submit the error (which I Will do). Should this entitlement be part of automatic signing? If yes, then it is a bug. If no, then it seems liker there is a "catch-22" scenario trying to run "locally" on an iPad. What am I missing? Gene

Thanks for the help. I have tried to run this locally (SIP off, developer on). A key step in the example is "4. In the "Build Settings" tab, change the "Code Signing Identity" value to "Sign to Run Locally" for all three targets.". This is not possible for the NullDriver target ( I get "Ad Hoc" signing not allowed in ... as a build error.) What am I missing? Thanks again! Gene

OK, it's working now! I don't know why, but it is. The Ad Hoc problem occurs when I have a provisioning profile for the NullDriver target. I have applied for an entitlement so that I can get the example to work fully code signed. Thanks again for the help, Quinn!
