This allows enabling debug- and trace-level logs even in a release
build. (This also means the job of filtering *out* those logs has been
moved up to build_ffi.sh, where previously it was specified in the
leaf crate's Cargo.toml.)
Rather than building the Rust parts of libsignal as part of `pod
install`, fetch them from build-artifacts.signal.org. This requires
adding
ENV['LIBSIGNAL_FFI_PREBUILD_CHECKSUM'] = '...'
to the consuming Podfile. The referenced archives are downloaded to
~/Library/Caches/org.signal.libsignal, and are unarchived as part of
the build. (The archives are outside the build directory so that a
clean build does not require a new download.)
Building with LibSignalClient as a local pod is still supported; in
that case everything will refer to the local target/ directory
instead. Use swift/build_ffi.sh to build as usual.
- Skip building for Catalyst in pull request testing, but make up for
it in the "Slow Tests".
- Update the README now that the Arm Mac simulator is a Tier 2 Rust
target.
- Remove workaround for one-time incompatibility with the Arm Mac
simulator.
The most common manual invocation of this script is when developing
using the local Swift package, not building a library to publish as an
CocoaPods artifact. The most common command should be easiest.
Also, update the Swift README to match the CocoaPods build process
added in b061e84189.
We're not actually logging anything yet, but this will let us do so.
The logging is initialized using a static constructor so that clients
of SignalCoreKit don't have to do any additional setup. This requires
an ObjC file instead of a Swift one. (When running as a Swift package,
logs will just go to stderr via NSLog.)
