IOS Developer

Responsibilities:

• Designed and targeted for iPhone, iPad, and iPod Touch devices running iOS version 6.1+; optimized for iPhone 5
• Implementation for application performed in Xcode 5.x; Thorough testing for most recent iOS versions (7.x & 8.x) handled in Xcode 6.x
• Utilized SQLite tables to store information and retrieved data to populate multiple UITableViews with necessary content
• User navigation facilitated using UINavigationController, and it's delegate methods, for simple transitioning between content views
• Implemented search bar to allow user quick access to specific items, by filtering results in real time, updating the UITableView's results
• Constructed User Interface based on wireframes produced by architect
• Created Unit Tests to ensure that underlying code from SQLite database passed expected data and did not output erroneous content
• Resolved numerous bugs throughout development as they appeared, utilizing NSLog statements, Breakpoints, LLDB statements, etc
• Developed in 2 week sprints using Agile/SCRUM Methodology
• Code Repository stored in Git; Repository functions manipulated using SourceTree
• Completed task of implementing the workflow involving populating the SQLite database and linking to a UITableView, appropriately displaying content. A singleton was leveraged for all interactions with the database.
• Acquired the experience and understanding that Swift code integrates fairly-well into an existing Objective-C application; quite familiar with bridging headers, and also translating Obj-C code to swift.
• Various versions of iOS 8.x output different warnings when executing the Swift code that was added for the SQLite workflow. The POC was maintained and updated for many changes like optional unwrapping/forced unwrapping among others.
• Both delegation and completion blocks where utilized/analyzed for callback purposes. Ultimately, it was decided that delegation would be the route to keep due to variety of events.
