Support Simulator and Catalyst targets

[keeshux]

Make Go library build correctly on iPhone Simulator and Mac Catalyst.

Script adjustments might appear inelegant, but the generated library has worked 100% on these targets. Tested in my production app for 6+ months.

@keeshux I have tried this on Mac M1 without success.

I get the error:

Error Domain=NSCocoaErrorDomain Code=4 "The file “SourcePackages” doesn’t exist." UserInfo={NSFilePath=/Users/houmie/Library/Developer/Xcode/DerivedData/project-ewigkyiwmukfdibbvzefbzcdfqhi/SourcePackages, NSUnderlyingError=0x600099ee17a0 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}

Does this fix only affect the app under Sources/WireGuardApp or also the library Sources/WireGuardKit?

Affects the library. I’ve used this patch successfully in my app for more than a year, and I do use a M1. 🤔

Sorry for the late reply. It works! :)

I just needed this one line: GOOS_iphonesimulator := iOS.

It’s a shame WireGuard is no longer properly maintained. None of these pull requests will ever be merged.

I didn't know the project had been abandoned. Anyone know why or what happened?

[houmie]

Yeah, look at the last commit from two years ago. The most recent actual fix in the library was on 2023-02-08. Check the dates on the pull requests—some are several years old. Not a single one has been reviewed or merged.

Hopefully someone will fork and continue to keep it alive. I consider Wireguard a very important piece of network infrastructure; it would be a real shame if it stopped working on macOS.
