iOS 17.14 Barometer no app data

[carrasco67]

Hello,

since my update (yesterday) to iOS 17.4 (iPadOS 17.4) my iPhone 13max (and my iPad pro too) sends no data to my Altimeter+ app and my barometer app, i guess it’s a bug?!? Can someone please confirm this?

greetings from germany

I’m having the same problem. My app called Barometer S10 and my other barometer app have no data since my last reboot which was when I updated. To confirm the problem I just restarted my phone again and still no data. Then I googled the issue and your post was the first google result.
So yes, there seems to be a bug in 17.4 that deactivated the barometer of all devices or won’t acknowledge the data.

Hello thx for replying! I guess we have to wait for a fix.

Yea, we will just have to wait for version 17.4.1 which will probably drop next week l, but don’t hold me to that date. It could end up being later. To clarify, I have an iPhone 14 Pro Max that I am having the issue on.

I have tested it on a 13 max on a Xs max and on my iPad and its the same behavior at all items.

Found a workaround. Apparently the issue is that as of 17.4, CMLAltimeter startRelateiveAltitudeUpdates now needs "Motion & Fitness" permission. However, normally in iOS just using a service requiring the permission will initiate the permission prompt by iOS to the user. The trick is to force requesting permission.

let recorder = CMSensorRecorder() recorder.recordAccelerometer(forDuration: 0.1)

will prompt the user for permission. Once granted, relative altitude data works.
A couple of other details. Need to add reason for permission request to info.plist. Recording accelerometer needs to occur on a non-main thread.

Hi,

thx for the workaround, but i can’t manipulate my info.plist.

greetings 👋

Surprising that one takes for granted that Apple releases IOS updates, and most of them show up with problems...
Used to be that one TRUSTS Apple and no workarounds or waiting for eventual fixes were required. Apple has lost most of its magic touch and ended up with so many frequent updates and fixes that it's becoming hard to continue being a fan.

Well Apple release Developer Betas so that the app developers can test their software and have a month to either fix their code or tell Apple to fix theirs.
I wonder if they did, or maybe could not be bothered?

Developer testing should be an instance for correcting new issues, not degrading working sensors as in this instance

So did they not consider that it stopped working in 17.4 beta was a new issue to be corrected before public release? Or didn’t they beta test it..

We have an barometer app: Barometer Plus, I report it in beta but they not care, they release it after I file a report 24hours. Now user only blame the dev with 1 star and bad rating. There is a work around but it is not working for iPad and some old iPhone.

Still awaiting some sign from Apple, regarding this serious problem. Apparently no release is forthcoming addressing this issue
