We are the Portland chapter of CocoaHeads (http://cocoaheads.org). We meet on the 2nd Wednesday of the month.
We get together each month and chat about current Apple and Portland happenings followed by either a lecture style presentation, when we have a speaker; or an organizer-mediated group discussion for a specified topic, when we don't.
If you're an out-of-towner planning to be in the area and want to speak, please reach out! I'm happy to be flexible on the meeting night to accommodate your schedule.
Both meeting styles allow you to come meet other Cocoa (iOS, OSX, Swift, Objective-C) Developers, Entrepreneurs, Startups from the Portland area to discuss how to design, build, and promote these apps and businesses.
