Can someone teach me how to post request to services on localhost

[Misaka-Tang]

I first time used moya framework and once I made a function want to get data from localhost:

func getUsrDatasReg(account: String, pass: String) -> Void {
    getData.request(ServiceType.usr(detailType: .register(account: account, pass: pass))){
      ret in
      switch ret{
      case .success(let ok):
        print(ok.data, ok.statusCode)
      case .failure(let err):
        print(MoyaError.statusCode, err)
      }
    }
  }

it didn't come into 'ret in' closure when I check breakpoint, and it says handler for XPC error: Connection invalid, why cause such problem, how to fix?

Are you running this code on macOS, iOS, or some other platform?

I developed these codes on IOS.

I developed these codes on IOS.

In that case, it’s probably a bug in iOS itself. Third-party code can’t use XPC on iOS, so unless you’ve done some complex reverse-engineering, that particular error is almost certainly not the fault of your own code.
