Debugging

  • Find memory leaks, abandoned memory, and other problems using Instruments and the Memory Graph Debugger.

  • Track down hard-to-find bugs with LLDB and other Xcode debugging features.

  • Troubleshoot layout problems with the View Hierarchy Debugger.

  • Write unit tests to ensure correctness of your code, and learn testing best practices.

Customizing UIKit

  • Bend collection views to your will with fully-custom collection view layouts.

  • Drive custom interactive view controller transition animations.

  • Authenticate to OAuth2 services and store credentials in the keychain.

Architecture

  • Work with the UIDocument API for modeling data in document-based apps.

  • Explore wrapping legacy APIs with more modern patterns to help write safer code.

  • Study reactive programming and create reactive pipelines for clean data flow management using the Combine framework.

Drawing & Graphics

  • Draw custom views and image data using Core Graphics and UIKit drawing routines.
