WWDC Badges With Methods

Objectives

1. Write custom methods to solve a few simple problems.
2. Call your methods to get the results that you need.
3. Run the tests to check your work.

Introduction

You did such a great job last year at the Apple Worldwide Developers Conference that they've asked for you back—and now they want you to handle a few more tasks as well. It's more work than you could possible handle by yourself given the time frame, so you'll need to figure out how to pass off the instructions by creating some methods!

The speaker list is new this year, but it boasts a similarly astounding group.

• Adele Goldberg
• Edsger Dijkstra
• Joan Clarke
• Clarence Ellis
• Margaret Hamilton
• George Boole
• Tim Berners-Lee
• Jean Bartik

In addition to the name tags, the conference manager also wants you to print a personalized greeting for each speaker to inform each of them of their dressing room assignment back stage.

Instructions

1. Navigate to the AppDelegate file. Declare three functions:

• badgeForSpeaker() that accepts one String argument named speaker and returns an String
• badgesForSpeakers() that accepts one Array of strings argument named speakers and returns an Array of strings
• greetingsAndRoomAssignmentsForSpeakers() that accepts one Array of strings argument named speakers and returns an Array of strings

3. Define badgeForSpeaker(_:) to return an interpolated string that includes the speaker's name submitted through the argument, in the manner of Hello, my name is <#speaker#>..

4. Define badgesForSpeakers(_:) to return an array of eight (8) interpolated strings that each read Hello, my name is <#speaker#>., one string for each speaker that will be at the conference.

5. Define the greetingsAndRoomAssignmentsForSpeakers(_:) method to iterate over the speakers argument array and create an interpolated string with each speaker's name and their dressing room number (which range from 1 through 8). The interpolated string should read: Welcome, <#speaker#>! You'll be in dressing room <#roomNumber#>.
