Part 2 of 6 splitting #2621. Builds on part 1 (#2637). Review commit 71df867a.

The Logbook lists Loop's last 7 days, newest first, with a section per day.

  • Day header: the day's insulin and carb totals, and its basal and bolus split.
  • Rows: manual and automatic boluses, carbs, basal adjustments, suspends and resumes, site changes and pump alarms.
  • Folding: runs of automatic boluses fold into one row that opens the list of doses. A day's basal adjustments open as their own list.
  • Filters: All, Bolus, Basal, Carbs, or Loop for what Loop did automatically.
  • Editing: carb entries can be edited or deleted with a swipe when Loop's own carb editor would allow it, and doses can be deleted. Editing opens Loop's existing carb entry screen in a sheet. The redesigned Add carbs form takes over in part 4.

Where it opens. It opens from Settings → Logbook, beside Trends, as a sheet with its own navigation and a Done button.

Logbook Logbook, edit or delete carbs

Screenshots are from #2621, where the Logbook is a tab.

Differences from #2621

  • The carb editor uses the existing CarbEntryView until part 4.
  • LogbookView takes an optional done closure. The footer says older doses are "on Trends", not "on the Trends tab", which doesn't exist yet. The new string has translations.
  • Review fixes: pump resume events now reach the Logbook. Add a redesigned interface with Now, Trends and Logbook tabs (next-dev) #2621 had a "Basal resumed" row that pumpEvents never produced. Also removes an unused IconTile initialiser.

Testing

On the loop simulator, through XCUITest:

  • Settings → Logbook. Folded automatic boluses → dose list → back.
  • Swipe a carb entry → Edit opens "Edit Carb Entry" with its 35 g → Cancel.
  • Carbs filter, then All. Done returns to Settings.

LoopTests (449 run on this part, on next-dev 5ee95cc6): all pass except BolusEntryViewModelTests.testCarbEntryDateAndAbsorptionTimeString and …String2, which fail the same way on plain next-dev ("12:00 PM" against "12:00"). Xcode's hosted test run stalls at test-host launch on this machine, so these ran in the app bundle under Xcode's simulator XCTest agent, with next-dev's test classes except the HealthKit-hosted DeviceDataManagerTests. Every part was built on its own, in order, on the loop simulator.

The series

#2621 is split into six PRs, in the order Pete suggested: statistics and Trends first, then the Logbook, then the home screen. Add carbs, the widget and Live Activity, and the appearance options follow as their own parts. Each part builds on the one before it and targets next-dev (5ee95cc6, after #2635), so a PR shows the earlier parts' commits too. Review only the last commit of each PR (part 1 has two: Trends, then what came across from Statistics). #2621 stays open as the combined reference until the series lands.

  1. [1/6] Add a Trends screen for glucose, insulin and Loop status #2637 Trends, opened from Settings
  2. [2/6] Add a Logbook of the last 7 days #2638 Logbook, opened from Settings
  3. [3/6] Add the Now home screen with Now, Trends, Logbook and Settings tabs #2639 Now home screen with Now, Trends, Logbook and Settings tabs, and the New Interface toggle
  4. [4/6] Rebuild Add carbs around a live preview of the meal #2640 Redesigned Add carbs
  5. [5/6] Restyle the widget, Dynamic Island and Live Activity for the new interface #2641 Widget, Dynamic Island and Live Activity
  6. [6/6] Add Day and Night app icons and an appearance setting #2642 Day and Night app icons and the appearance setting

The six parts together match #2621 apart from the changes listed under "Differences from #2621" in each part.

Merging. Merged in order with merge commits, all six apply cleanly. With squash merges, each next PR needs a rebase onto next-dev once the previous one lands, because it still carries the earlier part's original commit. I've checked that every one of those rebases applies cleanly and that the end result is identical to part 6. I'll rebase each PR as the one before it merges.

Strings. Each part adds only its own catalogue entries, with their translations in Loop's languages, and fills in translations for the existing keys it starts using. GitHub's line diff of Localizable.xcstrings can show deletions where Xcode's ordering interleaves new keys. Parsed as JSON, no part removes or rewrites any existing entry.

Trends reviews one period at a time (a day, 7, 14, 30 or 90 days) on
one screen: summary tiles (average with SD and CV, GMI, insulin, carbs
and boluses per day, Loop active), time in range, the daily pattern
(AGP), basal and bolus, insulin per day and Loop status with its gaps.
A one-day period leads with that day's timeline. Tapping a day opens
a day page with the insulin timeline and active insulin and carbs,
stepping a day at a time. The period exports as a PDF report or a CSV
with one row per day.

Inside Loop's 7 days the figures come from Loop's own stores, so manual
and automatic boluses, temp basals, historical targets and presets are
known. Older days come from Apple Health. Closed and open loop are
recorded from launch, because Loop's automation history only covers
36 hours.

Trends opens from Settings, beside Statistics, as a sheet with its own
navigation and a Done button. Statistics and Current Setup are
unchanged.

This is part 1 of 6 splitting LoopKit#2621.

Trends now carries everything Statistics shows that it lacked, so it
can take Statistics' place:

- Consensus goals: average under 8.6 mmol/L (154 mg/dL), GMI under 7%
  and CV 36% or less under the summary tiles; time in range over 70%,
  under 25% above and 4% below, under 5% very high and 1% very low,
  and CGM active over 70% on the Time in range card.
- Scheduled basal under Basal in Basal and bolus: the schedule that
  applied over the same days (the stored profile with presets), or
  today's schedule where the profile history doesn't reach.
- "Usually X U by HH:MM": today's insulin against the median by this
  time over the last 14 days, from InsulinDeliveryHistory as on
  Statistics. Under Total so far on today's Day view, and under the
  Insulin per day chart on longer periods ending today.
- "CGM data covers 5 of 14 days." under Summary when readings start
  partway through the period.
- Typed-in (fingerstick) readings are left out of every figure, as on
  Statistics. The day timeline still draws them.

Each new line reuses a pattern already on the screen: the Aim
footnote, the indented line under Bolus, and the muted footnote.

The Logbook lists Loop's 7 days newest first, a section per day with
its insulin and carb totals and the day's basal and bolus split.
Rows cover manual and automatic boluses, carbs, basal adjustments,
suspends and resumes, site changes and pump alarms. Runs of automatic
boluses fold into one row that opens the list of doses, and a day's
basal adjustments open as their own list. Filters narrow it to
boluses, basal, carbs or what Loop did automatically.

Carb entries can be edited or deleted with a swipe when Loop's own
carb editor would allow it, and doses can be deleted. Editing opens
Loop's existing carb entry screen in a sheet, which keeps the bolus
screen that can follow it clear of anything underneath.

The Logbook opens from Settings, beside Trends, as a sheet with its
own navigation and a Done button.

This is part 2 of 6 splitting LoopKit#2621, and builds on part 1.
