Starting with iOS 13.6, Apple decided to show a weekly notification to the user:

Your device identified 0 potential exposures this week, and shared them with SwissCovid.

To German this was translated to:

Dein Gerät hat diese Woche 0 mögliche Begegnungen identifiziert und diese Info mit SwissCovid geteilt.

This is misleading, as it does not say "[...] 0 positiv getestete Begegnungen [...]". Without this distinction, it might be understood that the app does not work at all, even though SwissCovid and Exposure Notifications are working as intended.

This issue was reported to Apple.

I have tried understanding how parameters are passed to the app.

I found some relevant code server side, which feeds into the bit below.

Could you please tell me more?

Hi everyone, thank you for this amazing solution.

We are from Cape Verde, We are developing covid-19 tracing app based on this implementation and so far we was able to setup the Backend and Android App (with Google approve on Google Play), but using the same Backend we are unable to put iOS app working , on every request we get this error: "Generic JWC framework error JWT verifier failed to verify the JWT String signiture" We have the same public key as the Android App, but only in the iOS App is failing. Can you please point us in the right direction how to better debug and fix this issues.

public func verify<ClaimType: DP3TClaims>(claimType: ClaimType.Type, httpResponse: HTTPURLResponse, httpBody: Data, claimsLeeway _: TimeInterval = 10) throws -> ClaimType {
     guard let jwtString = httpResponse.value(forHTTPHeaderField: jwtTokenHeaderKey) else {
         throw DP3TNetworkingError.jwtSignatureError(code: 1, debugDescription: "No JWT Token found in the provided response header field \(jwtTokenHeaderKey)")
     }
     do {
         let jwt = try JWT<ClaimType>(jwtString: jwtString, verifier: jwtVerifier)
         let validationResult = jwt.validateClaims(leeway: 10)
         guard validationResult == .success else {
             throw DP3TNetworkingError.jwtSignatureError(code: 2, debugDescription: "JWT signature don't match")
         }

         // Verify the hash
         let claimContentHash = Data(base64Encoded: jwt.claims.contentHash)
         let computedContentHash = Crypto.sha256(httpBody)
         guard claimContentHash == computedContentHash else {
             throw DP3TNetworkingError.jwtSignatureError(code: 4, debugDescription: "Content Hash missmatch")
         }

         return jwt.claims

     } catch let error as JWTError {
         throw DP3TNetworkingError.jwtSignatureError(code: 5, debugDescription: "Generic JWC framework error \(error.localizedDescription)")
     }
 } 

App zeigt Fehler siehe Screenshot.

Vielleicht ist es ein wenig unglücklich formuliert oder aber ein Bug. Habe mal beide Varianten aufgeschrieben.

A: Ist ist unglücklich formuliert, verständlicher wäre: "COVID-19-Kontaktprotokoll deaktiviert Aktivieren Sie die Funktion COVID-19_Kontaktprotokoll unter Einstellungen -> Datenschutz -> Health -> COVID-19-Kontaktprotokoll, damit das anonyme Tracing funktioniert.

B: Die Fehlermeldung meint tatsächlich "Benachrichtigungen" im Sinn von "Mitteilungen" und erkennt fälschlicherweise nicht, dass diese aktiv sind.

Klicke ich auf "Akivieren" werde ich umgeleitet auf die App Einstellungen von SwissCovid App. Dort kann aber nur Siri, Mitteilungen und Hintergrundaktual. eingestellt werden. Ich würde direkt nach Datenschutz -> Health verlinken. Sollte dies nicht gehen, würde ich die Verlinkung komplett sein lassen und nur per Text erklären wie es geht.

This is unfortunatelly a big pull request, but it remove all NS/UI prefixes that are not from Apple's classes. The issue can be localed under #57 please consider to squash the commits

For a while now I see this alert. The message in a previous version was about VPN (not using any) or insecure Wifi (nope, also happens on 4G). How to fix this?

When entering the key to report a positive test one gets an additional question from the IOS to confirm the release of information. Although the IOS language was set to German, the question is in English and may discourage the average user.

Operating system version: IOS 13.7

On iOS 13.5 the Error IEN11 was observed on some devices. In addition to that we got an insufficient memory popup on that device even though there is plenty of space available.

According to Apple this Issue will be resolved with the release of iOS 13.6.

Using Ver. 1.0.3 (200612.2347.141) on iPhone X running iOS 13.5.1 with Swisscom 41.0 plan, I get every few days a warning "Exposure Notification Region Changed: COVID-19 Exposure Notifications may not be supported by “SwissCovid” in this region. You should confirm which app you are using in Settings.".

Warning seems to come up in the area of Lake of Zurich (twice in Thalwil, once on the Ferry Meilen>Horgen mid-lake) while on 4G. Last warning was 2020-06-15 at 1708h UTC on the ferry.

Unclear if warning comes from app itself or from OS API. In any case, it implicitly and explicitly is a (wrongly working) geofencing issue and a s a such may trigger public concerns of a violation of "no GPS used" statements (although it does not look to refer to the core BT/hash function).

Hi, I have a question about the exposures. On my iOS (14.3) log, I can see a matching key from SwissCovid on every daily sinchronization since the 25th December, but I’ve received a warning notification from the app itself. Means that, I had contact with someone who was tested positive, but I had less than 15 minutes contact with him and/or at a distance of more than 1,5 meters? Thank you in advance for your help.

As noticed by Dr. Andrew Sempere you have a glaring mistake in the date formatter.

As explained by Apple's documentation:

. A common mistake is to use YYYY. yyyy specifies the calendar year whereas YYYY specifies the year (of “Week of Year”), used in the ISO year-week calendar. In most cases, yyyy and YYYY yield the same number, however they may be different. Typically you should use the calendar year.

So, all these format strings should contain yyyy and not YYYY:

:~/swisscovid-app-ios$ fgrep -r YYYY *
DP3TApp/Screens/Homescreen/InformBroadcast/CheckInSelection/CheckInSelectionViewController.swift:        formatter.dateFormat = "dd.mm.YYYY"
DP3TApp/Logic/Helpers/DateFormatter.swift:        dateFormatter.dateFormat = "dd.MM.YYYY"
DP3TApp/Logic/Helpers/DateFormatter.swift:        dateFormatter.dateFormat = "dd. MMMM YYYY"
DP3TApp/Logic/CheckIn/ProblematicEventsManager.swift:        formatter.dateFormat = "E, dd MMM YYYY HH:mm:ss zzz"

When scanning a UK-issued COVID certificate, it says 'invalid certificate' even though some of the details seem to be parsed.

I believe that other apps, including the French anti-covid app, parse it successfully, so would it be possible to add the ability to recognise UK-issued certificates?

The day I got sick I harrassed my Cantonal Medical Officer to issue me a Covid Code the same day. (Good, Swiss covid App law is enabling more managers to issue Covidcodes)

That concluded Exposure Tracking, which looks like this:

Now as I am being released out of isolation, they told me I am not subject to infection or infecting for 2-3 months.

Is there a possibility to reset Exposure Tracking after having activated the app? I may need the app back in 2-3 months.

With the cantonal orders changing by the day, it would be useful to have another tab to see where masks are required, maximum people per room/event, and so on.

I know this is a bit out of scope, but I think it would be the right place to help people staying up-to-date and give them recent information about cantonal orders.

I just updated to 1.1.0. I see in the description of what's new "New feature: app sharing". What is app sharing? Does this have anything to do with sharing data with other nations' backends?
