Can't build and run the ios-example-app in xcode due to readonly file asn1rt_nif.so
The file elixir-app/_build/ios_prod/rel/default_release/lib/asn1-5.3.1/priv/lib/asn1rt_nif.so always ends up with read permissions only at xcodebuild time no matter what I try. Where does the library come from?

There is a mixup here in the ios-example-app with the desktop_installer. The desktop_installer is responsible for creating the .exe/.dmg style installers for Windows, Linux, MacOS but it shouldn't be used for the Android and iOS builds. The ios-example-app I believe is not calling into it but rather using the run_mix and has probably a "mobile" target.
That said I think the obvious way to simplify this would be to make the desktop_installer aware of the MIX_TARGET=ios/android targets and then do the "right" thing instead of running the normal macos functions which break your build here.
To be more specific strip from your error output should never be called. This is only needed when packaging the runtime for desktop environments - for mobile environments all needed native binaries are already in the xcode/android studio project.
I got rid of the error by disabling stripping temporarily.
The only elixir / desktop related command included in run_mix is
mix release --overwrite
somehow the desktop_installer is invoked too nevertheless. any specific configuration required? Resp. where is the desktop specific processing triggered?
mix release will trigger the desktop installer if that is hooked in your release target as one of the steps.
