iOS Simulator Support for Stack Wallet

[fly536-spec]

Hi,

I’m trying to build Stack Wallet for the iOS Simulator on an Apple M4 machine, but I’m running into linker issues. I attempted to modify the iOS build scripts to support the simulator:

In flutter_libepiccash/scripts/ios/build_all.sh and flutter_libmwc/scripts/ios/build_all.sh, I changed:
rustup target add aarch64-apple-ios x86_64-apple-ios
to
rustup target add aarch64-apple-ios x86_64-apple-ios aarch64-apple-ios-sim
Modified the cargo lipo command:
cargo lipo --release
to
cargo lipo --release --targets aarch64-apple-ios-sim
Changed the library copy step:
cp target/aarch64-apple-ios/release/libmwc_wallet.a ${libs}
to
cp target/aarch64-apple-ios-sim/release/libmwc_wallet.a ${libs}
With these changes, the compilation of libmwc_wallet.a succeeded. However, I’m stuck at the final linking step:

error: Building for 'iOS-simulator', but linking in dylib 
(/Users/.../.pub-cache/hosted/pub.dev/cs_monero_flutter_libs_ios-1.1.1/ios/Frameworks/MoneroWallet.framework/MoneroWallet) built for 'iOS'

Linker command failed with exit code 1 (use -v to see invocation)

It looks like cs_monero_flutter_libs_ios only contains arm64 slices for iOS, so linking fails for the simulator. I have already tried both x86_64 and arm64 (Apple M4) simulator architectures, but both failed.

Questions:

Does Stack Wallet support running on iOS Simulator?

If yes, what iOS Simulator versions and architectures are supported?

Are there any known workarounds to link cs_monero_flutter_libs_ios for the simulator?

Thank you for any guidance!

Does Stack Wallet support running on iOS Simulator?

Not currently. While some libraries do compile nicely to iOS simulator supported binaries (as you've found out), there are some others that don't (or at least didn't when we initially added the libraries).

I wouldn't mind iOS simulator support but it is fairly low on our list of things to do at the moment
