Test

Use LoopWorkspace branch release/3.8.2 which is being prepared for release soon.
For Loop and LoopKit, modify to use branch ps2/ios26-fixes for each.

Configuration:

For iOS 26:

• SE 3rd gen phone running iOS 26.0.1
• CGM Nightscout
• Pump Simulator

For iOS 18:

• SE 2nd gen phone running iOS 18.7.1
• CGM Nightscout
• Pump Simulator

Use the same test table as from Issue #2360.

Each row in the table was tested with this version of iOS 26 and iOS 18 phones.

• The ✅ indicates nominal behavior that used to have an ❌.
• The word "ok" indicates it was nominal in the table from Issue 2360 and still nominal with this test
• The indication ✅2️⃣ indicates an SE specific failing that is still present with iOS 26 but now the change in therapy takes place as expected

The indication 2️⃣ is a different failure, see Issue #2267 - this issue is not fixed and only affects SE phones. I don't have a non-SE iOS 26 phone to test, but the therapy settings do get updated just not reflected in therapy settings screen right away and the fact that items that are marked ❌ before and are marked ✅2️⃣ counts as a fix for me. Example of a 2️⃣ is given below for basal rate:

• Modify basal rate, authenticate and the Therapy screen is shown with the old basal rate
• Return to main screen and then return to the Therapy screen
• Observe that the new basal rate is now shown
• Note that this issue is specific to SE phones for iOS 18 (and is seen for iOS 26)
