When setting duplicate as current, batch save original profile and
duplicate in a single call via profilesToSave. This is to avoid a
double call to willUpdateProfiles() when saving Core Data context.
In order to set current profile to one that has not been persisted
yet (the duplicate), we need to resort to a pendingProfiles map
where to look the duplicate up when setting currentProfileId.
Either way, iOS 14 cannot handle updating a "hot" change in a
presented NavigationLink. Changing currentProfileId binding while
in ProfileView messes up navigation completely (multiple push and
pop events). Avoid.
- Do the profile loading inside the model
- Allow setting current profile to a transient profile
- Check .placeholder before saving current profile
XXX: avoid loading active profile on iPad portrait.
Make action sync, but internally async (makeProfileReady). If not
doing so, UI on launch will not be able to show active profile
immediately. WelcomeView would appear for a moment.
Observe isReloadingCurrentProfile.
