The data in the NSString is all data which can be represented with the ASCII encoding I was caught out a few years ago when the iOS keyboard started automatically converting straight quoutes into curly open- and close-quotes, which are not ASCII. I wonder if something similar is happening to you? Maybe your date-time string has come from a formatter that has changed behaviour? Is there a reason you can’t convert to UTF-8?

I can't see a direct way to read the bytes in the tiff. Export it off the device and decode it with e.g. ImageMagick.

No.

What values do the bytes in the TIFF have?

My first guess would be that something is trying to undo a pre-multiplied alpha that never happened. Yes, probably. I have a vague recollection that CGImage's default behaviour is not what you expect and you need to set a flag somewhere. Call CGImageGetAlphaInfo and see if it claims to be premultiplied or not. But the numbers don't seem to work out. Is that something to do with gamma? I notice that you have set linearSRGB as the colour space.

Still no word from Apple on setting individual pricing. If anyone has suggestions I'm still looking for a solution. I wrote up how I set IAP pricing here: https://developer.apple.com/forums/thread/732527 You want to set the app's price, right? That's not the same, but maybe my notes will give you some clues. Is there a way for me to report incomplete DocC in the online documentation File a bug, ha ha. or even ask questions? You can ask here. Or Stack Overflow.

The App Store Connect API does not have a way to upload an app.

This is what namespaces are for. Static library written in Objective-c Note that the function names of the library are specified by the standard, so the function names cannot be changed. Looks like you are out of luck then.

I've submitted a request for an additional reason using the form here: https://developer.apple.com/contact/request/privacy-manifest-reason/ I've suggested that an additional reason be added for stat() etc., "to read non-timestamp metadata". I'll update this if I get a reply. I've also submitted a bug (FB12798615) saying that C++ timestamp-reading functions aren't on the list. Of course there isn't a suitable Feedback category for that so it's under "something else". I'll update here if I get a reply.

Is there a way to include capturing the latest date as part of the query? SELECT * FROM table WHERE d > date( (SELECT max(d) FROM table), '-1 year' ) With more complex sub-selects, it might look better if you move it to a WITH clause at the start. Turns out that SQLite supports a case statement. So I incorporated that and strftime into my query to adjust the date back to Friday if the current date is Saturday '6' or Sunday '0'. Julian Day Numbers are often useful for calculations like this. It possibly isn't quicker or clearer than what you're currently doing but it's a useful feature to be aware of generally.

use methods intended for your specific need (ie fileExistsAtPath to check if file exists) Right, so "change all the code" then; is that what you're going to do?

The old XML API required checksums for screenshots, and in fact I think the Transporter uploader relied on comparing checksums to determine whether to actually send the file Events are newer and weren't supported in the XML API. Fundamentally the answer is "it just does".

I believe that the last iPhone without Bluetooth Low Energy was the iPhone 4, which launched in 2010. Its current market share is zero.

The is no API for Bluetooth Classic on iOS What I should have written was "there is no API for things that you actually want to use, like serial ports, on Bluetooth Classic". Yes you can do GATT over classic - I had forgotten about that - but I'm not actually aware of any practical use for it. arduino file includes "bluetoothSerial.h" That doesn't look promising.
