For the past few years, Apple has been inviting student developers to attend its WWDC conference, which centers on development topics and software. A few students from this year’s batch are getting some more personal attention from Apple as it tries to raise awareness of the program and coding literacy via its Swift Playgrounds and other resources for students and teachers.

Most of those students, though, won’t get a surprise personal visit from CEO Tim Cook, which is what happened this week when Lyman High School student Liam Rosenfeld got to the Millenia Mall Apple Store in Orlando, Florida. Liam was there to participate, he thought, in an interview with myself and a local journalist from the Orlando Sentinel about his admission to the program.

As a surprise, and fresh off an appearance at the SAP Sapphire conference to announce an expanded partnership, Cook came to visit the store to greet employees, and to spend some time with Liam and his teacher, Mary Acken.

I was on hand to spend some time of my own with Liam, to talk to him about his experiences coding in high school and shipping on a global App Store. I also spoke to Cook about coding literacy, the SAP partnership and some other interesting topics.

The confab was set for Wednesday afternoon, with the store making an ideal meeting place given its rough proximity to the conference and airport. Liam arrived earlier than expected and some interference had to be ran so that Cook’s appearance and the surprise, could be kept secret.
