Uuids | Fast C # UUID implementation for .NET | Identity Management library

I am new to SwiftUI and would like to navigate to a "home" view in SwiftUI from any other view. I've created a home button that is added to the navigation bar on multiple views. The home button returns to the "home" view but the navigation links don't navigate correctly and display the wrong data.

I've read through multiple answers from others having a similar problem but the answers are at least two years old and SwiftUI has changed quite a bit since then. I've tried to implement many of the answers but always ran into other problems. Some functionality has been deprecated and I'm looking for a more forward looking solution.

Here is some code that shows the problem. In this example, I'm using the isActive parameter in NavigationLink to trigger the home button but this seems to break the NavigationLink. I've also tried using the tag and selection parameters and get the same results. From reading other responses, I believe using the ForEach statement in "ProductFamilyView" is the problem with referencing the wrong data. But, in this app, I need to use the ForEach statement to display the product families.

If I try calling ProductFamilyView(), nothing happens. In this example, I want to navigate back to the "ProductFamilyView". Is there another way to navigate to this view without using NavigationLink?

Say I have a DataFrame like below

I am trying to solve a problem without success and am hoping someone could help.

I have looked for similar posts but haven't been able to find anything which solves my problem.

My Scenario is as follows: I have a UIView on which a number of other UIViews can be placed. These can be moved, scaled and rotated using gesture recognisers (There is no issue here). The User is able to change the Aspect Ratio of the Main View (the Canvas) and my problem is trying to scale the content of the Canvas to fit into the new destination size.

There are a number of posts with a similar theme e.g:

calculate new size and location on a CGRect

How to create an image of specific size from UIView

But these don't address the changing of ratios multiple times.

My Approach:

When I change the aspect ratio of the canvas, I make use of AVFoundation to calculate an aspect fitted rectangle which the subviews of the canvas should fit:

I have a user transactions table that look like the following:

I have to store a bunch of UUIDs in integer format in a numpy array. Converting the UUID to integer format (128bits) is not valid since the maximum integer size that can be stored in a numpy array is 64 bits. Therefore I am trying to store the UUID as 6 separate integers using the fields style.

However I am unable to recreate the UUID from the numpy array values. Here is an example of the problem.

So this seems to be an issue talked about here and there on StackOverflow with no real solution. So I have a bunch of tests that all pass when run individual. They even pass when run as a full test suite, EXCEPT when I add in my TestCase ExploreFeedTest. Now ExploreFeedTest passes when run by itself and it actually doesn't fail when run in the full test suite as in running python manage.py test, it causes another test HomeTest to fail, which passes on it's own and passes when ExploreFeedTest is commented out from the init.py under the test folder. I hear this is an issue with Django not cleaning up data properly? All my TestCase classes are from django.test.TestCase, because apparently if you don't use that class Django doesn't teardown the data properly, so I don't really know how to solve this. I'm also running Django 3.2.9, which is supposedly the latest. Anyone have a solution for this?

I successfully am able to replace UUIDs with freshly generated UUIDDs in a file:

I have created a new Julia package from a template. I then went and used the UUID package to create a new UUID for the package via UUIDs.uuid4(). Now, when I try to do using myPackage I get the following error:

We do database dumps of Shopware 6 databases. The system stores UUIDs in binary(16) fields.

Now when dumping databases with the --hex-blob option, the data columns are written properly as hex (0x12345....) but we saw that default values are still binary data (see cms_page_version_id)
