This issue exists only in Xcode 13.2. So it is a bug. I suggest you report it using Feedback Assistant, and post the reference number here.

touchesBegan:withEvent: is available on tvOS 9.0+

When you tested this code did you chose a simulator or a real device? The original question did not specify a platform. I tested on macOS.

Can you be more clear about what you are expecting to happen, and what you are actually seeing?

This is an interesting idea, but I think it cannot be made to work. At first glance, a number of issues come to mind... Photo Library The Photo Library does not provide a feature where it sends a system-wide notification that a new photo has been added. PHPhotoLibraryChangeObserver This refers specifically to assets or collections that your app fetches. It can be used to synchronize a running app with the Photo Library. Background Modes The background operation of iOS apps is very limited. The available Background Modes do not cover anything like this use-case. Background Uploading On receiving a notification while backgrounded, it is not possible to upload data without some user intervention (e.g. by responding to the notification) Background Termination Backgrounded apps can be removed from memory at any time, when iOS considers that it needs available resources for other tasks. In this case, your app would just stop working (invisibly, i.e. with no warning).

It depends entirely on the vendor of the SDK that you are using, they set their own licensing terms. The point here being that they will not be licensing for a single app, but for all the apps that will be created using your SDK (which uses their SDK). You will need to talk to the vendor. Of course, if you are prepared to say who the vendor is, it is possible that other Developers here on the forum may be able to comment on their use of that same SDK?

Was that useful to know, @Stealthrt?

Did you make any progress on this, @mise?

Did you solve this, @BDCConfused?

Did you solve this, @CentricsDev?

It depends what you mean by "viable". Is it possible to learn and write a new app in Objective-C? Yes It it worth it? No Unless you have specific reasons for using Objective-C (such as an existing code-base, or a client who requires it). Swift has many improvements, and is a far better language.

Friendly Hint: paste your code (using "Paste and Match Style") into a code-block, then it will look nice, and people will be able to read it.
