Binding failed while starting the server

[srijanraj]

var address = sockaddr_in6()

if !os(Linux)

    address.sin6_len = UInt8(MemoryLayout<sockaddr_in6>.stride)
    #endif
    address.sin6_family = sa_family_t(AF_INET6)
    address.sin6_port = UInt16(port).bigEndian //This basically I think Cause error
    address.sin6_flowinfo = 0
    address.sin6_addr = try ipAddressToStruct(address: interface)
    address.sin6_scope_id = 0
    let size = socklen_t(MemoryLayout<sockaddr_in6>.size)
    // bind the address and port on socket
    guard withUnsafePointer(to: &address, { pointer in
        return pointer.withMemoryRebound(to: sockaddr.self, capacity: Int(size)) { pointer in
            return SystemLibrary.bind(fileDescriptor, pointer, size) >= 0
        }
    }) else {
        throw OSError.lastIOError()
    }

This part of the code is throwing the error. Error number 1 and error description "Operation Not Permitted". I am new to swift and trying to implement mock server on the ongoing project. Can someone have answer for this?

@srijanraj What's the port number you are binding to? As far as I know, if you are binding to port numbers which are below 1024 or a certain number, say you're binding port 80, it will usually require root permission to do so. I guess that's why you are seeing Operation Not Permitted error. If it's the case, I would suggest to use port numbers like 8080 or any number you like that's higher than 1024

I set port 8880 and I got the same issue, when I create severer from main app target it's okay, but when I try start server from uitests target for macOS app (for iOS it works) then I got same issue:

Embassy.OSError.ioError(number: 1, message: "Operation not permitted")

Additionally my entitlements are set:
