For those users who have opted-in to “share analytics with app developers”, you will get anonymised aggregated crash reports that appear magically in XCode’s “organizer” window. Regarding the privacy declaration, IMO all apps should disclose “diagnostics - not linked to you” because of this feature. But others seem to have different ideas.

No.

No, you don’t need them.

There isn't enough input data. It's waiting for more input.

You have the financial reports, which you can download manually from App Store Connect; you can also download them automatically using the Reporter java utility.

Do you get warnings when compiling?

Are you sure you want to support 10.10? It would be much easier to support only macOS 11 and newer. Exporting the SF Symbols images and including those in your bundle is technically possible, but legally dubious.

You aren’t the first to post here about this API being over-complicated and poorly documented - though most have been asking about IAP pricing, rather than apps. (See the “App Store Connect API” forum tag for more posts.) Personally, I’m hoping that there will be an easy-to-use utility on Github before I need to deal with this myself!

The SF Symbols app says it is available (in monochrome) since SF Symbols version 1.0, which means macOS 11.0. Do you have the SF Symbols app?

Generally those identifiers are not available to apps. There may be exceptions for e.g. cellular networks' own apps.

It sounds like you understand the issues involved with using the accelerometer. In some cases, "sensor fusion" can be used to combine inputs from multiple sensors to get useful results; search for "Kalman Filter". I think this was first used for the Apollo navigation computer. It might be possible to combine barometric pressure data with accelerometer data to measure things in the way you want. Have you looked at the barometric pressure data? Does Core Motion already do any of this for you?

That may not be possible if the higher version number is already on the app store.

This is an institutionalised bug; I filed FB5446792 in 2017.....

The problem is that a "UIRequiredDeviceCapabilities" (array) key is missing with the values "gps" and "location-services" in the Info.plist file Don’t set “gps” unless you really need 1m accuracy; it will prevent your app from working on wifi-only iPads. I think the non-gps locations on those devices should be good enough for e.g. a dating app - unless it’s a dating app for mountaineers! Also I’m. ot convinced that this is the solution to rejections. I agree with pianosmooth above, just do what they say however ridiculous. In cases like the original post, I’d show a default location with a prominent message saying “location services disabled, tap here to go to settings”. Don’t use (0,0) as your default location, that’s confusing; I suggest something like Alcatraz Island. Don’t choose Cupertino, they will think you have somehow bypassed the restriction!
