The first challenge in my Swift Rolls series is to create an iOS app where the user enters a line of text and it plays back a Morse encoded translation. The user can choose to play the message as a series of flashing lights or sounds. If they enter text that you’re unable to encode, display an error.
The rest is up to you. UI, technologies, etc.
My solution is up in this repo, please post your questions and solutions in the comments so we can help each other.
