Why does cargo tauri ios dev fail on a fresh project?

[lkdm]

Hello! I'm having trouble using the cargo tauri ios dev command on Mac OS. I'm wondering if there's something I'm doing wrong.

# Choose leptos
cargo create-tauri-app --rc
cargo tauri ios init
cargo install tauri-cli --version '^2.0.0-rc' # was prompted to update tauri-cli
cargo tauri ios dev

Output

Deploying app to device...
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):
Simulator device failed to install the application.
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.
Underlying error (domain=NSPOSIXErrorDomain, code=2):
	Failed to install the requested application
	An application bundle was not found at the provided path.
    Error Failed to deploy app to simulator: command ["xcrun", "simctl", "install", "5025A002-8EDF-4AAC-8D81-E10C31F162AD"] exited with code 2

Here's my cargo tauri info

I don't know if this is a red herring, but it seems that the xcode build process does not recognise the cargo command in the shell script

#!/bin/sh
cargo tauri ios xcode-script -v # continued...

When I run this command in bash it definitely exists.

Answer

So it turns out that there are issues with how PATH is resolved on Mac OS. Thank you to @jqpe for the original answer.

# for pnpm
ln -s $(which pnpm) /usr/local/bin/pnpm
# for node
ln -s $(which node) /usr/local/bin/node
# for cargo
ln -s $(which cargo) /usr/local/bin/cargo

Alternatively, there is a cleaner way to do this in the build scripts.

Additionally

• The tauri ios dev command must be run with the --open flag, then the build initiated from Xcode.
