getifaddrs() will return the IPv4 & IPv6 addresses of each interface. This in most cases, especially for IPv4, will be an address on the users local network. If you're after the users public IP address you will have to use some other method, such as visiting one of the many sites on the internet, via an http(s) request, that will reply with the connecting address.

This problem appears to be fixed in XCode 16 Beta 2. I don't see any mention of the problem in the release notes but I have successfully compiled and run an application on an intel Mac with macOS Sonoma 14.5 and Xcode 16 Beta 2.

I am seeing this same crash when running XCode 16 on a macOS 14.5 (sonoma) host. The minimum deployment for the project is macOS 10.13. There is nothing in the Xcode 16 release notes about macOS 13.0 being a required minimum deployment. so I don't think that is a solution.

Look in the 'More downloads' tab https://download.developer.apple.com/Developer_Tools/Xcode_14.3.1/Xcode_14.3.1.xip

And solved (I think ...) #if swift(>=5.9) self.clipsToBounds = true #endif

@eskimo Sorry to ressurect an old thread. I was just faced with this very issue trying to run a shell script using Process(). My program was waiting 10 seconds for enough data to fill the buffer before the 1 second updates from the script were presented to my read handler. On reading man setbuf, I saw a reference to setting the environment variable STDBUF. Inserting export STDBUF="U" into the script seems to have solved the problem and my program now receives each message as it is output from the shell script. I was unable to find reference to this environment variable anywhere else and am just asking for reassurance that it won't suddenly disappear.

Fixed with Xcode 14.3 beta 3

Submitted FB12051702 with a sample project demonstrating the failure.

Instead of looking to call Swift from C++ you should probably look at it the other way round. Use Swift as the main language for your development - it integrates beautifully with Interface Builder and is ideally suited for building a gui. You can then make calls to C/C++/Obj-C using the Swift bridging interfaces. Admittedly there is a bit to learn but I think you'll find Swift to be quite easy to become familiar with. I have found C/C++ to be very useful in Swift applications for dealing with Posix/System interfaces, then passing results back to Swift either as arguments or via closure/callbacks.

Not a commandline solution but whatroute (https://whatroute.net) will perform tcp traceroute.

I run the script under rosetta on an M1 with python3 by using: arch -x86_64 scripts/SMJobBlessUtil-python3.py check path_to_bundle It seems to work

If you are using an Apple Silicon Mac, have you tried running the script under Rosetta2?

I ran into a similar problem a few months back. The solution was to upgrade SMJobBlessUtil.py to python3. The issue was covered in https://developer.apple.com/forums/thread/699310 The conversion seems to work but I have only run it with my own use cases and not done any rigorous testing.

I have a suspicion that this problem is related to the libresolv security patches applied in https://support.apple.com/en-us/HT213257 and https://support.apple.com/en-us/HT213256 to macOS. Presumably this same libresolv security fix was also applied to iOS.
