nix develop && cd native/ios && pod install && xcodebuild -workspace Comm.xcworkspace -scheme Comm -destination generic/platform=iOS -allowProvisioningUpdates

Once nix develop finishes it prints "Welcome to Comm dev environment! :)" and puts me "inside the nix shell." Is there a way I can get the rest (cd native/ios && pod install...) to run "inside" the nix shell after nix-develop in a single command?

Getting the following when I try running the test plan on an aarch64 Mac:

(could definitely be doing something wrong, so let me know if there's a step I'm missing etc)

Is there a way I can get the rest (cd native/ios && pod install...) to run "inside" the nix shell after nix-develop in a single command?

This is what ended up working (as in the command ran after entering the shell, build still failed) :

cd native/ios && nix develop --command pod install && xcodebuild -workspace Comm.xcworkspace -scheme Comm -destination generic/platform=iOS -allowProvisioningUpdates

Just kidding, it worked 2-3 times after retrying... not sure what happened the first time around

edit:

Running nix develop --command pod install && xcodebuild -workspace Comm.xcworkspace -scheme Comm -destination generic/platform=iOS -allowProvisioningUpdates works

Running nix-develop and then running pod install && xcodebuild -workspace Comm.xcworkspace -scheme Comm -destination generic/platform=iOS -allowProvisioningUpdates "inside the nix shell" doesn't work?

Don't know enough about the subtleties of nix to know why, but I think it has something to do with differences in how Xcode config is being picked up

Restore /usr/bin on PATH for pod compatibility

• jon added a comment.Jul 7 2022, 12:44 PM

@atul yea, this is a bit of an awkward area for nix, as the apple_sdk usually lags behind what mac is currently providing.

I've updated the diff to include /usr/bin as the first PATH entry, I was able to do a pod install without issue.

Unfortunately until I get setup with a Apple developer account, I can't really make use of XCode directly yet

@atul it should "just work" now

This feels super impure but unfortunately is probably the right decision for us in order to move forward here.

To be clear, will this make the Nix shell always include /usr/bin in $PATH, or is it somehow scoped just to the XCode build? (Fine if it's universal, I just want to make sure)

will this make the Nix shell always include /usr/bin in $PATH

For macs, yes.

stdenv.mkDerivation and by extension mkShell will bring in the GNU version of many commands, including sed, base64, and gnu-make which have significant command-line differences.

The other option would be to provide an "ios shell", which would just be focused on ios development. E.g. nix develop .#devShells.iOS. This would have the benefit of downloading less things, but a bit of a pain if you want to switch between them.

Makes sense to me, thanks for explaining!

Observation unrelated to this diff – this line is >80 chars long. Can we find a way to keep it within the 80 chars limit?

I've been good about that in the past week, but only really keeping myself to under ~100 before then. I can remedy this in another diff
