Sleep App SwiftUI Template

Drift, a sleep and recovery companion for a smart ring: a complete Xcode project with pairing, daily readiness, sleep stages, trends, widgets and three brand presets. 14 screens and 4 flows in Drift, as a SwiftUI app template.

A sleep and recovery app on four tabs. First run pairs the ring on a turning dial, sets a bedtime goal, asks for wind-down reminders and an account (Sign in with Apple, or continue without one) and hands off to a StoreKit 2 paywall. Today pages through daily scores on a tilted card rail with a tick dial; Sleep reads last night's stages; Trends shows the weeks; Profile holds the ring, bedtime reminders, the subscription and sign out.

Screens

Every screen in Drift, 14 in all, each a SwiftUI view in the Xcode project. In Frost, Velvet and Graphic, light and dark.

First run

Welcome, permissions and the questions that set the app up.

  • Welcome

    Drift opens on its ring drawn over a score card's arc, with one line on what the ring and the morning score do.

    Built onReadiness

  • Pair Your Ring

    Pair the ring on the tick dial, whose ticks fill as it bonds, through a designed drop-out and a retry.

    Built onReadiness

  • Set A Bedtime

    Turn the dial through quarter hours to set a bedtime goal, with the wake time it implies under the figure.

    Built onReadiness

  • Wind-Down Reminders

    Allow one quiet reminder thirty minutes before bed, shown as it lands on the Lock Screen.

Account and subscription

Sign in, verification and the paywall.

  • Sign In

    Sign in with Apple to back up your sleep history, or continue without an account.

  • Drift Plus

    Start Drift Plus on a yearly plan with a fourteen-day trial, or pick monthly.

Built from the library

The library screens this template wires together, in the order someone meets them. Each one installs on its own too.

First run

Welcome, ring pairing on the dial, a bedtime goal, reminders, Sign in with Apple (or continue without an account) and the StoreKit 2 paywall. Runs once, then records completion.

Tabs

Today, Sleep, Trends and Profile. Today is the Readiness rail; Sleep is the night's stage timeline.

Implementation notes

How it behaves, what it handles, and the decisions behind it.

SleepApp is one root view. On first launch it runs Drift's own first run: a welcome with the ring drawn over the score card's arc, pairing the ring on the Readiness screen's tick dial (the ticks fill as it pairs), a bedtime goal you set by turning the same dial, then the Purchase screen's StoreKit 2 paywall. Closing, purchasing or restoring finishes onboarding and records it under a completion key, so the root switches to the home on its own.

There is no tab bar. Three round floating buttons carry the app: Sleep on the left, a capsule for Today and Trends in the middle, Profile on the right. Today is the Readiness screen: Sleep, Readiness, Recovery and Balance cards on a tilted rail, with the dial underneath turning through the last fourteen days. Sleep is the Sleep screen: last night as a stepped stage timeline you scrub, with stage totals as capsule bars. Trends stacks each night's stages into capsule columns and sets the share of nights on goal as a giant figure over a grid of dots. Profile is Settings, with sign out back to first run.

Adapting it

  • Products: pass your App Store Connect ids as productIDs. Until they exist, the paywall shows its designed "plans didn't load" state and its close button still finishes onboarding.
  • Your ring: nights and scores come from DriftSample at the top of SleepApp.swift. Map your ring SDK's or HealthKit's samples to [SleepSegment] per night and your scores to ReadinessDay.
  • Pairing: SleepAppPairStep.pair() simulates the ring. Call your SDK's discovery and bonding there and drive the dial's progress from it.
  • Theme: everything follows the theme you set on SleepApp. Without a brand it wears Drift Frost; SPBrandTheme(.driftVelvet) or .driftGraphic re-skin every destination, including the cards, stage colours and motif.

The Xcode project

The download is a complete project on Tuist: SwiftData nights behind a repository protocol; sleep, recovery, balance and readiness scored against a seven-night baseline, with the contributors behind each; pairing with a designed failure and retry; a bedtime goal and wind-down reminders; an account step before the paywall, with Sign in with Apple or continue without an account; loading, no data and error states on Sleep; Trends by week and month; Readiness and Last Night widgets; three presets; unit tests and a first-run UI test.

Notes

  • Not @main: put SleepApp() in your own WindowGroup.
  • Enable the In-App Purchase capability before testing purchases. A real ring also needs Bluetooth usage strings, and Apple Health the HealthKit capability.
  • Drift's scores are sample math for general wellness, not medical readings.
  • Previews ship with the file: first run, home, and home in each Drift preset.
