Summary

iOS doesn't report when an app will be suspended (placed from background into a non-processing state) nor does it seem to fire a notification once the app has resumed. There is some confusion about this as there is a notification when the app becomes "active" or will resign the "active" state, however this is not always the right value needed. iOS Apps have a number of states:

1. Active: App is in the foreground (frontmost) and there are no notifications or menu's pulled over it. Pulling a menu down or getting an external notification or text message will cause the app to "resign" active, and resume active once the alert has been dealt with.
2. Background: App is not in the foreground but still processing. This happens briefly before suspend if there are no background tasks running, or can be a permanent state if there is a long running background mode (audio, location, etc) running.

// The image is originally animated on to the view controller then added to the scroll view.
// So, there might be some animation residue in here.

Pull Request Etiquette

Why do we use a Pull Request workflow?

PRs are a great way of sharing information, and can help us be aware of the changes that are occuring in our codebase. They are also an excellent way of getting peer review on the work that we do, without the cost of working in direct pairs.

Ultimately though, the primary reason we use PRs is to encourage quality in the commits that are made to our code repositories

Done well, the commits (and their attached messages) contained within tell a story to people examining the code at a later date. If we are not careful to ensure the quality of these commits, we silently lose this ability.
