How to connect an iOS device to your computer via a SOCKS proxy

Say you're running a virtual machine on your work computer. Say this machine, for whatever reason, can only connect to the internet over NAT - as in, it does not get it's own IP address. Say this VM is running a webserver, and you need a device outside of your computer to connect to it.

If only there was a way to get your work computer to 'share' it's network, so that you could get at that VM… Here's how you do it!

For all instructions, I assume your work computer is a mac

1. Get your computer's IP address:

@objc public enum AppContextError: Int, CustomStringConvertible, CustomNSError, LocalizedError {

  case badParameters
  case unknownError
  case connectNotSupported

  public static var errorDomain: String {
    return "AppContextError"
  }

 NSManagedObjectContext *context = object.managedObjectContext;
    while (context != nil) {
        NSError *error = nil;
        BOOL result = [context save:&error];
        
        NSAssert(result != NO, @"[ERROR]: Context was not saved");
        
        if (result) {
            context = context.parentContext;
        } else {
