Support for M1 MacBook Simulators

Support for M1 MacBook Simulators

[Igor Bozin]

Hello,

I am trying to build a project which contains a dependency on WireGuard through a Swift package.
The laptop I am running on (M1 MacBook) can't build the project, because libwg-go can't be compiled for the arm64 architecture for iPhone simulators. 
I am aware that Network Extensions functionality doesn't work on simulators, but not making the binaries available for simulators makes it impossible to test other features of the App in any project that WireGuard is part of.
Are there any plans to support simulator architectures as well, or any other workarounds for this?

Best regards,

Igor

Hey Igor,

I believe I encountered this in the past.

I'm not sure what your exact setup is since you mentioned it's a separate project presumably depending on WireGuardKit, but I can build libwg-go for arm64 just fine using the trick I mentioned in the linked thread. Just add this flag to Sources/WireGuardKitGo/Makefile.
GOOS_iphonesimulator := ios

Hope it helps.

Hello David and Neutron,

my setup is following: I have added the WG library as a SPM dependency to my project and followed all steps as described in the Github readme from wireguard:

https://github.com/WireGuard/wireguard-apple

What I am trying to do is to build a framework which has some other functionality on top and wrap WG within that framework. I can build just fine for iOS arm64 and iPhone simulator x86_64 architectures.

When I try to do the steps you described in the linked message, to build a framework for arm64 iPhone simulator, I still get the following error when I try to build the project with an arm64 simulator target:

/Users/igorbozin/Projects/cyan-internetprotectionsdk-ios/InternetProtectionApp.xcodeproj Building for iOS Simulator, but the linked library 'libwg-go.a' was built for iOS.


Is there a way to modify the makefile, so I can build a version of libwg-go.a for arm64 iPhone simulators?

Best regards,

Igor
