It’s been established that generally speaking background apps cannot record audio while the foreground app is already reading audio data from the microphone, but are there exceptions? For instance, is there an exception for certain Apple apps? If so, and there’s a special exception that most programmers don’t know about but some Apple’s engineers do and perhaps some hackers do as well, wouldn’t the mechanism that allows that eventually be exploited?

I'd like to know: Let's say there's a backgrounded app which has microphone access, such as Signal or SoundHound or Shazam. It's established that these apps are allowed to record audio in the user's environment even after being backgrounded, seemingly for as long as they want and even upload that sound data. But can they ALSO continue recording even while another app that is in the foreground is using the microphone, such as the Phone app or Signal?

I'd like to find out: Can backgrounded apps record audio? In the past as I recall, I found that backgrounded apps were pretty restricted and couldn't do much of anything. However I'm not familiar with the current state of affairs. With iOS 15.8 and above, can backgrounded apps record audio if they've been given permission by the user to access the microphone? Thanks.

I received an email saying this: Your iOS Distribution Certificate will no longer be valid in 30 days. To generate a new certificate, sign in and visit Certificates, Identifiers & Profiles. If I don't correct that situation, what will be the consequences for my apps' users? The Apple documentation is vague on this, because they seem to automatically assume that I plan to comply and renew the cert. However I don't own a Mac at present, nor an iOS device. My apps are monetarily free, so no financial incentive exists to buy either. If I don't renew the distribution cert again (maybe by borrowing a Mac), will my apps' existing users be adversely affected? FWIW, my apps don't support iCloud in any way. I would also note that the "Certificates, Identifiers & Profiles" section isn't visible anywhere; I'm using Firefox.

I've inherited some code thatr seems to have undergone a bad refactor. Instead of separating some code out of BigProject into LittleProject framework and making LittleProject a subproject of BigProject, they did something else: They made the separated code into a separate Target. Unfortunately, the code associated with that separate Target cannot any longer #import the header files of BigProject. But much of the code in there still needs to use parts of BigProject. In addition, adding a Header Path into BigProject's header files and making it recursive has no effect. That is how insane this is. What could cause this inability of code associated with one target to import .h associated with another target? The .m files cannot even see the other target's .h files. How would I fix this? Thanks.

Hi folks, In Xcode, Option-Click brings up a Quick Help popup that contains text that is too small and blurry to read. I did not find any option in the preferences for this. Could it be a genuine oversight by the Xcode team? My employer has provided me with a 1080p monitor, which is why the text is blurry, but the small point size is due to Apple's decision. How can I increase the font size that is used in the Quick Help pop up window? I'm willing to modify the executable if necessary, to save my vision.
