So you want to learn Swift? In New York City, you can do it for free.

Developers keen to learn Swift can now do so for free in New York City.

“The interest in Swift has been so intense that we’re breaking it down into three different classes to keep up with demand,” said Turntotech marketing director Sean Moskowitz to VentureBeat in a phone interview.

Moskowitz and his software development firm TurntoTech throw tech-centric workshops and events at their space on 5th Avenue for free. Nearly 900 people have already RSVP’d for the Swift how-to, the first of which kicks off Wednesday.

Moskowitz said about 650 of the attendees are experienced programmers.

“We didn’t want this to be overcrowded,” Moskowitz said. “The response has been unbelievable.”

The first Swift class will be held this Wednesday at 6:30pm ET at Turntotech’s workspace on the fourth floor. The second Swift workship will be held the following Wednesday at the same time. The final introductory class will be held June 23.

Apple unveiled its new programming language Swift last week at the World Wide Developer Conference 14 last week in San Francisco, to a packed house of 6,000 reporters and developers.

Well-regarded software engineer Sam Soffes told VentureBeat that developers love Swift, and that it will likely phase-out Objective-C down the road.

He called Apple’s move a bold one because of the sheer legions of developers weaned on C.

“Throwing out everything and learning something new is a tough thing to do. Objective-C is many developers’ livelihoods. Messing with the tools we’ve been using for years to get our job done is hard to hear at first,” Soffes said.

“Apple does a great job making a case that the new tools are the way to go.”

Swift is indeed more than a possible replacement for Objective-C.

“One of the ways Apple is making it’s case this time is speed. Swift is really fast at working with collections. That alone is a big win. Its new syntax is also really great,” Soffes said.

“I think Objective-C developers will come to love Swift quickly.”

Moskowitz said Turntotech is the first outfit in the entire New York City ecosystem to offer free Swift classes. The overwhelming turnout tells Moskowitz he and his 12 member team are on to something.

“We’re hosting a huge introduction to Swift,” Moskowitz said. “It’s going to be great.”
