QUESTION
I am using Eclipse Jetty HttpClient to send POST requests to a server, for load testing.
TL;DR: Is there a way to use a single HttpClient instance with multiple user credential sets to a single destination URL?
For this purpose, I need to log in to the server-under-test as separate users. Even though HttpClient is thread safe, it does not appear to support this with a single instance, due to its shared authentication store.
The solution seems easy, just use one HttpClient per user, or per thread.
This works okay, except that HttpClient creates a number of threads (5 to 10 it seems) for each instance, and so my load test needs a very large heap or else it will start throwing OutOfMemory exceptions when trying to create new threads.
For example, in this very basic test, the first set of credentials is used for all subsequent POSTs:

This is how you would do it:

This is a very similar problem to one I had before (which no one could answer). I'm trying to create a dynamic list in which I can edit elements. As far as I can gather, the recommended way to do this is to have an EditView, with bindings, that's activated by a NavigationLink in the LIst.
So, I've done that. It appears to work at first, until I realised that each NavigationLink would only work once (is this a bug?). I can't think what I could have done wrong to cause that.
Then I thought perhaps I can switch to in-place editing by having the EditView in the List. I devised a theoretical way to do this, then tried it in my code. And at first it seemed to work great. However, if 'edit in place' is on, deleting the last element causes 'Fatal error: Index out of range'.
I've bundled my whole code into one file so you can just copy and paste into Xcode to try for yourself.
I'm starting to think that maybe XCode 11.3.1 is far from the finished article, yet.

Answered 2020-Jan-23 at 12:00Ok despite my comment I tried to get to a solution and I might found an acceptable one:
I had to remodel Person
... The whole indices was the issue of course but I couldn't exactly find out when what happens. I even tried with a local @State
which updates the view and then updates the array of the @ObservedObject
...
here are some links which could help to further investigate though...
How do I set the toggle state in a foreach loop in SwiftUI
Also this link here shows how to update members of an observed array generically which is pretty cool!:
