coronatracker's Issues

Refactor the data structure

The current design is something like this:

struct Report {
   let region: Region
}

struct TimeSeries {
  let region: Region
}

class DataManager {
  let reports: [Report]
  let timeSerieses: [TimeSeries]
}

We need to refactor this design to move reports and time series under Region. So every country region will have its report and time series, and sub-regions for the states/provinces/cities. And above all, we'll have the World region that has the country regions as its sub-regions.
So, basically, it's a tree of regions, which makes sense.

struct Region {
  let report: Report
  let timeSeries: TimeSeries
  let subRegions: [Region]
}

class DataManager {
  let worldRegion: Region /*
      subRegions for countries
           subRegions for states/provinces/cities
  */
}

This is a breaking change, so I suggest waiting until this task is completed before working on a new feature.

Plans to publish the ios app on appstore?

I think CoronaTracker is in a really usable state right now, would love to see it on the appstore.
I know that Apple put a few restrictions on those type of apps a few days/weeks ago, but the fact that this one is using the data from CSSE at the JHU might be a point?

Type of expression is ambiguous without more context

Getting the "Type of expression is ambiguous without more context" in the latest build.

Check the screen shot

Type of expression is ambiguous without more context

I'm getting multiple errors of one particular type:
Type of expression is ambiguous without more context

Did I miss a step? I downloaded the zip. It fetched the packages without errors when I built it.

history for daily data

after a period of 24 hours, the data (look screenshot) will be reset. it would be good if you could choose past days. what there were the maximum values (all values) before the 24h period reset.

sorry for the bad english

Overlapping labels in state view for "Most Affect Countries"

Occurs on iOS and macOS.

Use current math to estimate infected but not reported on city level

Story: As a user, I would like to know what the estimated infected but not reported is, ideally on a city level, but even on a state level for starters would be helpful. Sources for the math can be provided if needed, but a couple inputs would be fine as well.

License violation?

This app is in App Store.

Is dayly statistics removed or...?

In last days I haven't seen the dayly statistics under (as shown in attatched pic), is it removed or is there something else?

Miss that information troumendssly.

Build I use is from Master.

Maps does not load white screen

Currently running into issues with the maps screen not loading it just appears white.

Corona Tracker

Support for Mojave

Hi, any chance to get it to work on on Mojava 10.14.6 (18G4032)?

Thanks.

feature suggestion - log scale graphs

I suggest the option for graphing "daily new cases" on a log scale graph, possibly also useful for other graphs as well.

Can’t build for iOS

Hi,

I attached a screenshot of the erros I get during the runtime, if you need log files let me know.
Tried this on Xcode 11.3.

Add support for 10.14

"You have macOS 10.14.6. The application requires macOS 10.15 or later." Why ?

Swedish update to new strings in Localization.

English: "chart.delta" = "Daily New Cases";
Swedish: "chart.delta" = "Dagliga Nya Fall";

English: "data.source" = "Source: %@";
Swedish: "data.source" = "Källa: %@";

Ideas & Discussion

Any suggestions or ideas? Feel free to share them here!

Could this display be used?

Could this technique be used in the app for a different way of displaying the data?
Example: New cases vs Reported deaths for the day, splitting it in two

Thank you for your app. Stay safe and clean!

View of granular data points for regions or provinces

I split this issue into bugs (in my opinion) and a related feature request. It's about the new view of granular data points for regions or provinces.

Bugs:

• The semicircular background layers for displaying numerical values at the provincial level are displayed empty at a certain zoom level, so they disturb the overview without displaying information.

• The numerical values for the provinces overlap the numerical values for countries, and are displayed one level higher than the country values, so that when interacting, one involuntarily retrieves the numbers of the province instead of the desired country values.

Feature Request:

• Personally, I don't like the way the numbers are displayed at the regional level, but that's certainly a matter of taste. What is simply imprecise, however, is the simultaneous representation of both levels on one country. For those countries for which regional sub-values are available, could you possibly frame the country circles accordingly, so that a tap on the country circle "folds out" the regional figures?

The data is not updated

Platform: iPhone SE
iOS: 10.3.2

I just updated to the latest version today and am running into this issue on my phone.
Can't update the data. Please make sure you're connected to the internet

Of course I've checked and my phone is online and all other apps are able to connect to the internet.
I also checked via Cellular, WiFi and even VPN and I always get the same error.

Can't scroll region view anymore

Scrolling up to see the region view controller was broken in the update v1.3 for iPhone 8 and 8 plus. Only the top of the graph can be seen.

e13ee18

Scroll seems to be broken on all iPhones actually. Just that the graphs can still be seen on the bigger screens.

Incorrect stats ?

Why is France not appearing here ? It’s more affected than Brazil or Russia.

Thanks

Small errors in diagrams

I noticed a few little things:

• In the diagram of the most affected countries, the 100,000 steps are different sizes. The first 100,000 are smaller than the subsequent ones, which distorts the diagram and makes the USA appear even more disproportionate in this case. This also applies to the full screen view after tapping.

• There also seems to be some kind of rounding error. In the diagram of the worldwide development of cases, the same applies to the same extent as to individual countries such as Slovenia, which has just over 1,000 cases. In the case of the worldwide case development, 1.1 million cases become 1 million, in Slovenia 1,100 cases become 1,000 cases. After rounding, both cases are therefore shown twice with step 1 million and 1,000 respectively.

High Memory usage Mac App

The mac app uses a lot of ram. Starting at about ~110 MB all the way to ~300 MB.
Is this due to it being a catalyst app? It doesnt need that much ram on the iphone..

Search icon not visible

When using iPhone SE iOS 10.3, the search icon is not visible despite being clickable.

Build Mac APP have problem

Build iPhone APP is OK, but while build mac app, it have internal error. Do not know why.

Add chart for daily deaths and recoveries

It would be great to be able to change "Daily New" from cases to recoveries or deaths.

Please consider adding this to the already great app!

Latest Update no longer shows graphs

With the code update as of today, I can no longer see the two graphs below the first bar graph.
Was that purposely removed?

Map Annotation Popup intermittently contains stale data

Map Annotation Popup intermittently contains stale data

Initial investigation shows that this appears to be due to ReportAnnotationView instances having their report data updated only initially.

For added clarity, please see attached screenshot.

doesnt work on ipad

i tried to compile it for my ipad (5. Generation), but the app crashes as soon as i try to start it.
i only tried it on my ipad because when i try recompiling it for my iPhone6s im getting
this error msg: The maximum number of apps for free development profiles has been reached.
Domain: com.apple.dt.MobileDeviceErrorDomain
Code: -402620383

i only had the corona tracker on my iphone, nothing else which i compiled myself.
i deleted an older version, rebooted but still the same. i dont know how to solve this.
everything i found with google didnt help, any help welcome...

thnx
Helmar

App crashes after 3-4 days since last build

For some reason the app always crashes about 3-4 days after the build. Restarting the iPhone or exiting manually does not change this. This is now the case for several versions. Maybe it has something to do with memory management, the handling of the loaded data?

Xcode 11.4 doesn't compile the project

Since I have updated to Xcode 11.4 I get the following error:

Any ideas how to fix this?

It looks like the 3rd party libraries needs a fix like this one:
https://github.com/onevcat/Kingfisher/pull/1420/files

Feature request: Disable animations

However animations look nice at first sight, it's getting extremely annoying after you click the third marker on the map after each, and you still have to wait that second to see the graph. I think you should add an option to disable them or at least constraint to 0.1-0.3 sec in length.

No live map

On the application I can't see the map with live stats. I can see all the graphs. Just not the map.
iPhone 11 Pro Max iOS 13.3

Question

The app look very beautiful and profrssional.
can you please create a version for windows?
with c# language using winforms / wpf,
or just an exe for download and install the app on windows.
its will be great, thank you!

Validation Fails

I have the latest Xcode version, my code base is basically the same as yours. The change I made is not related to the problem libraries:

"Tracker" App

Hi there,

you name you're app a somehow "tracker".
For me this is confusing.
Now they started to develop real tracker apps, to track down people who are infected with
covid-19 and tracking their contacts.
Your app is only a dashboard, or?
So I would like to suggest to take out the "tracking" term from your repository.

What do you think about that?

Greets,
Ted

P.S.: I started to develop such a tracking app.
https://github.com/MadTed/PD-Tracking-App-hackthepandemic/blob/master/description_of_the_app.txt
And of course, it should also have a dashboard. Perhaps you like to contribute?

Stay at Home / Shelter in Place Orders

Is there any way we can map this out? From a data science perspective, conjoined with infection rates this seems like it could be a useful model to look at (in terms of the success of isolation efforts). Alternatively, I might be inclined to think that this information could be misleading to people who are not already in Stay at Home / Shelter in Place zones and may misunderstand or underestimate the risks associated with not isolating.

Thoughts? Is this data even available? Could we map it into the app?

Crash on app launch: Can't load 3rd party libraries

Now #37 is fixed, but if I try to compile and launch the app crashes with the following error:

dyld: Library not loaded: @rpath/Disk.framework/Disk

Provinces only appear when the phone language is English

@FluffyDev2019 :

The apperence of regions does Only appear IF I change my system language to English, if I have Swedish chosen (as is Default to most Swedes), no Regional "Dots" and no information to it is shown.

Shouldn't Regional dots/data be available even if other languages then English as system language is chosen?

With English set as system language:

With Swedish set as system language:

Missing data for Florida

App shows no data in Florida. However WHO has cases but location includes County name. Also Colorado. Kansas shows nothing but who has cases there also.

Adding unit tests?

Hi, I really like your project and appreciate that you're doing this! Would adding some tests to the app be beneficial? I want to help but this is my first time trying to contribute, and was wondering if this would be something I could help with. Thank you!

Plus-minus sign for death cases

Version 1.6 Mac

When I checked the situation in the US, it showed that the increment of death cases in the US was “+-15”. I guess it is caused by the decrease of reported death cases (needs to be confirmed by checking the dataset)? I’ve attached the screenshot, please notice the US death cases.

Type of expression is ambiguous without more context

I'm getting this error

Build fails for macOS

The build instantly fails with the following error:

multiple configured targets of 'CSV' are being created for macOS
multiple configured targets of 'Disk' are being created for macOS

Use worldometers.info for live data

The current data source is not up to date sometimes. A better option is worldometers. But there is no available API for this website, so we have to scrap the numbers and match country names with those from the time series.

City-level data for more countries

Detailed and official data sources for many countries here and here.

We need to look into them, and probably incorporate some of them into the app to show city-level data for more countries.

Currently, the app does that for the US, Canada, Australia, and China.

Adding localization

Might be a good idea to prepare this app for localization. No idea how this works on code level, but glad to help out with a German translation as soon as it becomes possible on code level.
