**when i try to use a path-based dependency to treat LibSignalClient as a development pod.

this command finished successfuly :

full XCode Build logs are here

[jrose-signal]

The pod lib lint error is because pod lib lint expects both simulator targets to be present, even though it'll only test one of them. For the xcodebuild failure, you'd need to share the full error logs for that build phase for us to make any guesses about what went wrong.

@jrose-signal i just edited the issue , you can find the full logs file at the end of the issue

[matinrn]

same here

[amirvatani]

i add ENV['LIBSIGNAL_FFI_PREBUILD_ARCHIVE'] = 'libsignal-client-ios-build-v0.46.0.tar.gz' to my podFile ,

and also build manually using (CARGO_BUILD_TARGET=aarch64-apple-ios-sim swift/build_ffi.sh --release)

now all errors fixed in all tests pass successfully,

now i get the following error when trying to run ios from terminal ( errors generated in xcode attached in the image )

Now that you're building for a real device, you have to use the real device's target triple for CARGO_BUILD_TARGET when you build_ffi.sh. x86 simulator, arm64 simulator, and arm64 device are all separate.

@jrose-signal i get the above errors ( in xcode image )when i run using pod in xcode ,
but when i want to build it manually using :

CARGO_BUILD_TARGET=x86_64-apple-ios swift/build_ffi.sh --release --generate-ffi

i got these errors ( available in the url ) : Logs

[jrose-signal]

Ah, you need a newer version of cbindgen too. Sorry the instructions for that are incorrect! The latest version should work instead of the ^16.0 that's listed.

[amirvatani]

@jrose-signal now it ends with lots of warning ( log ),
now i get xcode error ( avaiable in above image ) using both of these :

• pod 'LibSignalClient', :git => 'https://github.com/signalapp/libsignal.git'
• pod 'LibSignalClient', :path => 'path.to.local.built.libsignal.folder'

[jrose-signal]

As noted, you need to build all three targets for libsignal_ffi.a if you are using LibSignalClient as a path-based dependency.

This is ultimately not a support channel. Please take this to https://community.signalusers.org.
