xcodebuild 14.2 create xcframework doesn't recognize mac catalyst static library build in rust - xcode

Question

So I've build the following fat binary
➜ wallet-core git:(m/rust_fix) ✗ lipo -detailed_info build/local/catalyst/libwallet_core_rs.a
Fat header in: build/local/catalyst/libwallet_core_rs.a
fat_magic 0xcafebabe
nfat_arch 2
architecture x86_64
cputype CPU_TYPE_X86_64
cpusubtype CPU_SUBTYPE_X86_64_ALL
capabilities 0x0
offset 48
size 1038808
align 2^3 (8)
architecture arm64
cputype CPU_TYPE_ARM64
cpusubtype CPU_SUBTYPE_ARM64_ALL
capabilities 0x0
offset 1038856
size 2649760
align 2^3 (8)
Using the tutorial https://nadim.computer/posts/2022-02-11-maccatalyst.html
and use xcodebuild to build a xcframework from different fat libs in order to create a universal framework:
#!/bin/bash
set -e
TARGET_NAME="libwallet_core_rs.a"
TARGET_XCFRAMEWORK_NAME=../swift/WalletCoreRs.xcframework
BUILD_FOLDER=../build/local
CRATE="wallet-core-rs"
HEADER_NAME="WalletCoreRSBindgen.h"
create_xc_framework() {
rm -rf $TARGET_XCFRAMEWORK_NAME
xcodebuild -create-xcframework -library $BUILD_FOLDER/$TARGET_NAME -library $BUILD_FOLDER/darwin_universal/$TARGET_NAME -library $BUILD_FOLDER/aarch64-apple-ios/release/$TARGET_NAME -library $BUILD_FOLDER/catalyst/$TARGET_NAME -output $TARGET_XCFRAMEWORK_NAME
}
cd rust

cd -
cp build/local/release/${TARGET_NAME} build/local/lib/
Everything was working fine until XCode 14.2 start to spit out this spurious error:
error: unable to determine the platform for the given binary '$HOME/Documents/C++/wallet-core/build/local/catalyst/libwallet_core_rs.a'; check your deployment version settings
lipo tells me that the build/local/catalyst/libwallet_core_rs.ais perfectly valid fat binary.
That's what gives rustc spec info about the aarch64 target:

Everything outside of catalyst works well, but I wonder how to fix this error if anyone encountered it.
