This represents a significant architectural improvement for remote Loop control, moving from Nightscout-based commands to a more direct and secure APNS-based approach.

The app stops responding when modifying various rows in the Configure Loop APNS Settings section.

Enclosed is the most recent ips file from my iPhone 15 pro.

Once configured, the remote commands worked well. I'll do more testing after the crash is fixed and the branch conflicts are resolved.

I tested again. (I used the latest commit, d593cce, merged dev to it and resolved the conflict).

I can select all and remove each of the items in:

• LOOP APNS KEY ID
• LOOP DEVELOPER TEAM ID
• LOOP APNS KEY

I can then add each item back in.

I can use the Camera to rescan the QR code URL if the row is already filled out.

• If I clear that row - the app hangs, when I restart, it is cleared
• If the row is cleared and I use the camera to scan, the app hangs but when I restart, the row is filled in

With this crash I am getting ips files on the SE 2nd gen but not on the iPhone 15 pro, even though they both act the same. Here's one:
