I wrote a comment shortly after this post but it doesn't seem to have taken. I did as you ask, logged out and back in - no change. (forgot to restart Xcode). So now, a few days later, restarted Xcode and voila - it connected!!!

Logged out and back in, then tried again. Got the same 400 message (which I'll guess is coming from the Watch not Apple servers. Tell me what you need in a bug report.

Thank you for posting this, but I had seen and tried most of this already. But, I have made more progress (which is too long for a comment so see my reply).

Thanks! I sorta got it working. The idea (for others) is to just call the extension code from an app. I'm now stuck on one thing (an Xcode issue). This app I have is creating the QuickLook extension. I'm trying to include the extension code in my app side, but Xcode is only letting me copy or move the file. I tried creating symbolic links to the files, but Xcode then doesn't recognize them as files (WTF?!). Again, thanks! This is a great solution to the problem of testing!

Uh, what? I have an iOS App in the Store. I want to know, if while my app is running, and a user of that App goes to Settings, and changes one of MY app's settings, will the system send any kind of UINotification (or App Delegate message) to my App. I can't find anything through searching, but maybe its lurking there and I just didn't trip on it. This is a coding question!

THANK YOU!

Thanks! It occurred to me after posting this might be the case. But why Apple is the default in ios16 different than the past? Lots of pissed off customers…

iOS 15 having to put this view as subview 1 - 0 doesn't work for the date view.

I'm on latest iOS 15.5. Building on latest Xcode. Trying to test out some other code in a really large mostly Objective-C app. An no, I don't get a crash just the message. Obviously something is generating it. Why would me making ranges have anything todo with it? I'm bottlenecking it at the bottom of the app. The string length varies from run to run. Even it if was always 43, then what would I do? Bottle neck as I have and test for string length == 43? I'm already testing location.

I thoroughly searched the project and can find no protocol extension to handle this. All I can conclude at this time is that the original developers, years ago, discovered themselves that they could not get rtsp to work, but then just left the code they had written in the app. Its just so bizarre! Thanks so much for your response!
