Prefer `XCTAssertEqual` and `XCTAssertNotEqual` over `XCTAssert` When tests fail, the more specific matchers provide better error messages.

Update screenshots for new screen sizes: - Update fastlane snapshot config with new devices - Remove SimulatorStatusMagic, which doesn't work as easily on newer simulators - Configure fastlane snapshot to make the status bar pretty - Annotate screenshot test case with `@MainActor` as required by the snapshot helper function A few issues I ran into: - The iOS simulator inherits the 12/24-hour time format preference from the macOS host *at the time the simulator is created* and does not expose a way to change this setting via either the Settings app or an `xcrun simctl` command. The fix was to manually run `plutil -remove AppleICUForce24HourTime ~/Library/Developer/CoreSimulator/Devices/[Simulator UUID]/data/Library/Preferences/.GlobalPreferences.plist` for each simulator before running fastlane snapshot. - There are imperceptible differences between screenshots rendered when my MBP is running on battery power vs running off a power adapter. I opted to capture screenshots when connected to power. - The (in)visibility of the home indicator at the bottom of each screenshot is flaky. Most screenshots don't include it, but I had to re-generate several of them to get them all without home indicators.

Authenticator iOS App
App Info
Authenticator
Authenticator is a simple, free, and open source two-factor authentication app. It helps keep your online accounts secure by generating unique one-time passwords, which you use in combination with your other passwords to log into supporting websites. The simple combination of the password in your head and the rotating passwords generated by the app make it much harder for anyone but you to access your accounts. • Easy: Simple setup via QR code, "otpauth://" URL, or manual entry • Secure: All data is stored in encrypted form on the iOS keychain • Compatible: Full support for time-based and counter-based one-time passwords as standardized in RFC 4226 and 6238 • Off the Grid: The app never connects to the internet, and your secret keys never leave your device.
