[Swift][Pod] Failed to download 'libSignalClient'

[JuyeonYu]

pod 'LibSignalClient', git: 'https://github.com/signalapp/libsignal.git' pod 'SignalCoreKit', git: 'https://github.com/signalapp/SignalCoreKit.git'

following ReadMe.MD, I added those 2lines of code in my Podfile. but I can't install the pods.

this is the log.

-- [!] Failed to download 'libSignalClient': [!] /bin/bash -c set -e set -euo pipefail CARGO_BUILD_TARGET=aarch64-apple-ios swift/build_ffi.sh --release CARGO_BUILD_TARGET=x86_64-apple-ios swift/build_ffi.sh --release CARGO_BUILD_TARGET=aarch64-apple-ios-sim swift/build_ffi.sh --release CARGO_BUILD_TARGET=x86_64-apple-ios-macabi swift/build_ffi.sh --release --build-std CARGO_BUILD_TARGET=aarch64-apple-ios-macabi swift/build_ffi.sh --release --build-std

so I excuted rustup target add aarch64-apple-ios but same condition.

is there something can I do?

I'm sorry, the error message should be clearer than it is: you specifically have to run rustup target add … for the toolchain that LibSignalClient uses. You can do this by running the command in the Pods/LibSignalClient directory, or by running it as rustup +$(cat Pods/LibSignalClient/rust-toolchain) target …. Let me know if that works (you'll have to add the simulator targets as well).

[JuyeonYu]

Thank you for the reply. now I can't run the command in the Pods/LibSignalClient directory, because Pod install goes to fail. There is no LibSignalClient directory under Pods.

Sorry for my insufficiency. now I'm building an iOS chat app with MacOS Monterey, and decide to use Signal protocol for encrypt.

for the Rust, I installed Rust with curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

default host triple: x86_64-apple-darwin
default toolchain: stable (default)
profile: default
modify PATH variable: yes

this is the config.

rustup 1.24.3 (ce5817a94 2021-05-31)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.61.0 (fe5b13d68 2022-05-18)`

it's my Rust version information.

for the iOS, I made new project with Xcode and ran Pod init in the Podfile, under use_frameworks!, I added those pods git link following READ.MD and Pod install goes to fail with the error log.

is this correct process for using libsignal? is there something I misunderstand, please let me know.

[JuyeonYu]

In my brew list, there is another Rust! that was the problem. I removed it. all things clear. thank you.
