So last year I wrote my own APRS tracker using Pythonista.

APRS stands for Automatic Packet Reporting System

Using a python library for it and pythonistas access to location and the internet I was able to write my own software to report into the system using my Call Sign and display my location of aprs.fi

The following is my code which I never really tided up at all.

Why does Apple make it so hard to do the simplest of things. (Like on Windows and Android they have API’s for this.)

Like how is know what WIFI is around you going to hurt them or the End user.

That’s annoying... (Why do people not say the full truth in SO answers like seriously)

Hm... strangely that only shows the wifi I am connected to. The snippet (from SO) is supposedly supposed to show all networks.

So I am trying to convert the following to python (can’t code block it on mobile...)

@import SystemConfiguration.CaptiveNetwork;

/** Returns first non-empty SSID network info dictionary.
 *  @see CNCopyCurrentNetworkInfo */
- (NSDictionary *)fetchSSIDInfo
{
    NSArray *interfaceNames = CFBridgingRelease(CNCopySupportedInterfaces());
    NSLog(@"%s: Supported interfaces: %@", __func__, interfaceNames);

    NSDictionary *SSIDInfo;
    for (NSString *interfaceName in interfaceNames) {
        SSIDInfo = CFBridgingRelease(
            CNCopyCurrentNetworkInfo((__bridge CFStringRef)interfaceName));
        NSLog(@"%s: %@ => %@", __func__, interfaceName, SSIDInfo);

        BOOL isNotEmpty = (SSIDInfo.count > 0);
        if (isNotEmpty) {
            break;
        }
    }
    return SSIDInfo;
}

But even when I load the SystemConfiguration framework I can't make an instance of CaptiveNetwork. Or am I totally doing this wrong.

For pretrained models.

Possibly. I am still poking around in the list of frameworks and stuff. Looking for stuff that is possibly new in iOS 11.

Oh... so I guess my assumption that you probably already saw it was wrong.

I think this is how people normally use LMZA and why even a self compiled one causes Apple to flag it.

As of IOS 9 the Data Compression Framework has supported LMZA so it should technically be possible to write the python LMZA to use that framework instead of a self compiled or the builtin undocumented apple version.

I realize you probably already looked at this. But just noticed this api just now.

Specifically https://github.com/muehlemann/InLine/blob/master/inline/Camera.m

Helps with this project.

https://github.com/Ja7423/PhotoCamera

Also has a lot of information I will be using.

Welp I have found that I can look at Obj-C source of OS projects to figure out how to use the apis

Rip! Beta is dead.

Well just figured out I still need to do a lot of work. Because both of the examples use the older API that can't take RAW images or take settings

Also I found your old barcode read that still works that uses it.

Yes very interesting. This is why I really should have looked here instead of asking in slack about this. (Could have searched camera....)

I have been doing some research into using the camera from objc_utils to allow for changing the Exposure and ISO along with some other settings.

I will update this post when I am on my computer.

I have mostly been using Py2 because of the craziness of bytes and strings being separate things now.
Also generally there are more libs still on only 2.. (Or both)

Sorry for the crazy bump.

But I am not doing steganography. As I am not hiding data inside of a image. It's more of I am storing the data as pixels instead of as normal binary.
