Task/Issue URL: https://app.asana.com/0/0/1208832732122403/f

Description:

  • Migrate the app’s startup flow into a state machine with clearly defined states, each specifying its dependencies to ensure the necessary resources are available before execution.
  • Keep the flow primarily synchronous as it currently is, with some exceptions for existing async code.
  • Define explicit state dependencies to avoid optional objects, ensuring clarity about what exists in each state.

Steps to test this PR:

  1. Make sure you're assigned to "experimental" state machine group (change appBehavior random value inside AppDelegate)
  2. Please go through all smoke tests. https://app.asana.com/0/1202500774821704/1201879741377823/f
  3. Run the UI tests.
  4. Repeat for old behavior.

Definition of Done (Internal Only):

Device Testing:

  • iPhone 14 Pro
  • iPad

OS Testing:

  • iOS 17

Posting my comments so far. I'll still need to do some smoke testing.

Can this be called during testing? Would it cause inconsistencies?

We should be able to easily pass remoteMessagingClient to Settings and Debug view - it's already done for multiple objects.

case .launching(let application, let launchOptions):
return Launched(application: application, launchOptions: launchOptions)

return Launched(stateContext: makeStateContext(application: application))

return handleUnexpectedEvent(event)

Just a note: make sure to rename the pixel (if you want to avoid using app version param) before actual tests so we can easily see if things are not working as expected.

What is a bit concerning here, is that we change the moment things are instantiated and when data is red from the storage - and it's potentially earlier than it used to be in the old implementation so things may not be ready yet. E.g. some of the code here for VPN workaround was instantiated lazily in Task {} when did finish launching has already returned to the OS.

talked through on 1:1, it shouldn't cause any issues, as there's no work happening in the inits

Went through smoke tests, including data clearing, automatic keyboard, VPN, app lock, sync, opening URL, default browser, context menu items. All seems to be working fine.

Good effort! Looking forward to what comes next.💪
