One challenge was a thread break bug that always happened when I added a navigation controller and included Settings. I was not able to find a clear solution towards that. This did allow me to explore more features which I am excited to implement later on. I look forward to learning more. ## License Copyright [yyyy] [Name] Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
