FileManage

I am new to SwiftUI (iOS App Ver 14.x) as I normally use Xamarin.

In this case I need to have the application specifically written in SwiftUI. (I am aware that some stuff still needs UIKit).

I have got my head around it though I am generally speaking struggling to get to grips with where and how to store stuff.

For example (greatly simplified) let us say I want the following:

All in the same view.

Two form fields:

First Name: … Last Name: …

A Button that says, “Add Photo”.

A Button that says, “Save Locally” (N/a but just for info, to be later uploaded to a web service that isn't always available at some point).

Now doing all the standard stuff this is pretty straight forward.

BUT.

I want to encrypt the form input (once converted to JSON, note I can convert to JSON easy enough).

I also want to encrypt the image before it is stored. (the real app has more than one image).

The stuff will be encrypted in the real app using asymmetric encryption (which I understand well, again this is not so relevant here).

But for the sake of example, I am happy to just ‘encrypt’ the JSON and picture as two separate files using something simple just to show the idea. XOR it or something simple to show.

My question is where is the best places code wise to do this with some basic examples if possible. I know this is a little subjective but just something simple and obvious. Click button, run this func, do this type of thing etc.

Where do I store stuff (which I am finding a bit all over the place)? This is my main source of confusion being honest.

My understanding is that you would use a FileManager object and the documents directory (though I am not sure if this is best practice, or even the right place.

The requirement from a client is that nothing is stored unencrypted for compliance reasons (completely ignoring anything Apple have in place good or bad).

I'm using Laravel 7.3 and need to update to 8 because of plugins needings

I'm reading the documentation but as I'm a noob as in English like in computing I have some errors and problems

First of all, I followed this :

Update the following dependencies in your composer.json file:

I am trying to install the Vue Filemanager to my package.json. However, when I try to install the package using npm install and npm run dev I get this error:

I need some help cause I don't know what's wrong with my new project!

I stared a new Empty Project (.NET) in VS 2019, added same references to create form and draw different controls on it like buttons, labels and so on... Everything looks good for me and I don't get any warning/error. When I run my project it shows the form how I expected, but it's empty... no buttons or labels on the form, only the whitish coloured blank window [see picture].

I'm not familiar with the empty projects, so probably I missed something.. I tried to type "InitializeComponent()" to the class constructor but I got an error "Error CS0103 The name 'InitializeComponent' does not exist in the current context".. I don't use the designer as this is an empty project and it's not come with it (and I don't need it!), so I suppose I don't need this method?

Here's the code and pictures to help localize the issue.. Probably just a noob mistake somewhere but I can't figure it out.. Please help!

I have a function that copies a file from a given URL that is returned via a system file picker.

So once the file picker returns from documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) I'm getting the first URL from the list of URLs and passing it to my function.

The copy function is like this:

I'm trying to train a CoreML sound classifier on device, on iOS, and I have been struggling to find learning resources on the topic. The sound classifier is used to determine whether a snippet of music is similar to a collection of other songs. Hence the output of the classifier is just a label of either "match" / "no match".

It is so simple to train with the CreateML app workflow. I am simply trying to get the same kind of training on device in iOS, but as far as I know (please correct me if I'm wrong) iOS doesn't support createML.

I have been trying to adapt code from various source to get this to work in an iOS playground. I can only find resources on training image classifiers, these two have been the most helpful (1, 2).

Please see the code that I have come up with so far below.

I have TableViewController and AudioPlayerViewController. I have a problem with using MPRemoteCommandCenter. For example: In TableViewController I click on cell and go toAudioPlayerViewController next I lock device and control my music with MPRemoteCommandCenter - all works fine. But if I further unlock device return to TableViewController go again to AudioPlayerViewController lock device and press play/pause button my music will play two times at the same time. If I will repeat the action my music will play three times at the same time. And etc... How to fix it?
