• App centers around a tab bar controller to allow users several easy ways to get to events; users can browse via home, search for particular events, see nearby events, and lastly check on favorites
• Concurrency workflows handled with NSOperationQueues using NSBlock/Invocation operations; originally Obj-c then done via Swift
• CoreLocation and MapKit leveraged for conducting searches of events/exhibitions near the users location; in regards to location tracking, whenInUseAuthorization was used for this app
• Search featured smart use of the UITextField delegate methods to update results on a per-character pressed basis
• All webservice calls where done via AFNetworking, and JSON parsed accordingly with NSJSONSerialization; AlamoFire also tested via a POC
• Reachability was used with AFNetworking/AlamoFire, and various Categories like the UIImageView async image set method where utilized to optimize the app
• Simple constraints were set up under wAny and hAny size class to tackle most use cases. Certain outliers where handled in the diagonals of the size class 3x3 grid
• For offline handling listened for the kReachabilityChanged notifications. With both cellular and wifi off, a user would still have access to favorites, and recent searches
• CoreData was added to project to persist event/exhibition information
• SLFramework and Accounts Framework used to allow users the functions for sharing information on Twitter and Facebook
