admittance | Role based access control implementation for node | Runtime Evironment library

I am having an issue decoding a JSON file. I am learning SwiftUI and I am working with the IMDB API. I copied all the certificates in a JSON file that I copied into the document to have available offline

Below the JSON structure: I did not copy all as it is quite long but you can see the structure In swift UI I created a Structure like this:

SOLVED

I've found a solution, as can be seen in the answer below.

I've been trying quite a lot of different ways to solve this problem..

To allow the Header to not be above the drawer, I have nested navigators inside the DrawerNavigator. When opening the header(with the property drawerType: 'slide'), it slides all the content of the nested navigator, but not the header itself. The header keeps its place, and the Drawer Content is rendered underneath the header.

Is there any way to make the header slide as well, besides rendering it separately for each component in the nested navigator?

I'll post some of my code if necessary, but it'd be quite a lot, if I have to link all that could be relevant. I'd mainly like to know if what I want is even possible.

Thanks in advance!

EDIT:

In an attempt to recreate this issue (in order to supply a comprehensible code-snippet), I realized that I have actually set the header as part of the Drawer Navigator. I've done this to be able to use a custom header, and every attempt I've made to set the header in the nested stacks, have resulted in it being overwritten by the drawer. Either, by not appearing, when giving the drawer header: null, or when not supplying any header at all, returning the default (blank) header, instead of my custom one.

I will further attempt to solve this and provide a code-snippet, solution or admittance of defeat, by the end of the day.

I am writing a code to simulate the behaviour of a five-layer dielectric structure. The method used is the TMM methods.. Inputs are the incident angle on the structure. With this strcture, what I expected is a zero transmission after the critical angle (which is 65.1 for this refractive index stacks) and an unexpected peak after a while (this is due to an optical tunneling effect). The formula used are taken from paper: http://ieeexplore.ieee.org/document/6417944/

Do you know why the structure acts like a Fabry-Perot instead? Am I missing something in the loop in your opinion?

Thank you very much

Given the root routing module

I'm a car park admittance thingy for college. Basically what is does when it's run, a window comes up, asks the user to enter make, model, colour, and reg plate. Then it saves this data to a list, array or whatever. The user presses a button to enter their car into the car park, and also to see what cars are currently in the car park. When I press admit vehicle, I need the data to be saved to this list/array/tree, and also for a integer variable to decrease by one. Here's the relevant code. There is more, but this is the relevant bits.

I need to measure admittance in my RLC. Is there any clever way to do it? I know that there is special block for impedance measuring, can I make use of that?
