Just like the Android version of the app, MySJ Trace on iOS does not carry the beta label as per the version for Huawei devices. Unlike those platforms, the feature somehow does not require iOS users to turn on location permission for it:
The document also said that the MySJ Trace supports devices with iOS 10 or newer but then again, the MySejahtera app itself requires at least iOS 11. Users can update their MySejahtera by going to the app’s listing on the App Store within their iPhone or iPad and then press the update button.
