Summary
We were retaining references to GoalViewController meaning it was not correctly cleaned up when leaving the view. There were two causes of this.
GoalViewController
andDatapointTableController
(fixed via weak ref)Fixes #590
Validation
Ran the app in the simulator. Navigated to the goal view and back several times. Ran the XCode memory graph debugger.
Before this patch: Observed many GoalViewController still in memory
After this patch: No copies of the class in memory
Logged out and logged into the app. Observed there was no longer a crash reading goal objects.
