Looking for Designer to Help Build New Visual Identity for Philly CocoaHeads

UPDATE: We have found a designer. Thanks to everyone who replied.

Philly CocoaHeads is a local group for people doing iOS and other Apple-related development, a chapter of the world-wide CocoaHeads organization. We run monthly events in and around Philadelphia to help our members learn, socialize and share.

My name is Mike Zornek, and I help run the group which has been growing dramatically over the last few years. We currently do have a group website but are planning a major reboot and with that reboot we’d like to build a visual identity(for the website, business cards, twitter avatar, etc.). To date we haven’t done much in that area, leaning on pre-built WordPress templates and a the national CocoaHeads symbol, a hand drawn mug with a happy face.

The initial scope of this project is the branding, logo, visual identity, though we may be interested with help on the overall website design as well.

This is a paying gig. If you are interested please contact Mike Zornek at with your availability, samples of your work and guidance on your pricing. Thank you.

Baseball Hack Day

Baseball Hack Day is a one day event of design and development on anything baseball related. This is the second year they will be running the event here in Philly. This year they’re running it at the same time as events in Boston and Montreal.

It will be held March 28th at CityCoHo on 24th and Walnut, from 9:30 am - 6:00pm. They’re going to have a couple of prizes to hand out to winning teams including Phillies tickets from TicketLeap and an assortment of prizes from A View From My Seat. MLB is going to be judging a grand prize from the top teams in each city. That team and city will have bragging rights for the rest of the season and I’d love to have Philly be the one to grab that prize. They’d love to see some fellow iOS devs there.

It should be a fun day.

Show and Tell

Size Classes, Michael Raber

iOS 8 adds new features that make dealing with screen size and orientation much more versatile. It is easier than ever to create a single interface for your app that works well on both iPad and iPhone, adjusting to orientation changes and different screen sizes as needed. Mike will demo the basics and anwser your questions.

Fastlane, Curtis Herbert

Fastlane lets you define and run your deployment pipelines for different environments. It helps you unify your apps release process and automate deployments. Curtis recently add this to his Slopes project and will share his findings.

Last Week in PhillyCocoa Slack

This post is a weekly review of PhillyCocoa Slack for those who want a quick recap of what’s happening in the community. (Please send feedback if you find this type of post useful.)

General topics

@parrots shared a link about app pricing

@blackfrog summarized his feelings: “I think the general point is that you need to charge what’s appropriate to your software within market tolerances.”

@zorn gives some advice on how to build products for an audience: “Other thing to keep in mind is: it’s way easier to convince 5 people to buy your software than 10 or 20 people — don’t go generic, build a very opinionated product that solves real problems, find people who like your opinion and will pay for it ..”

@blackfrog asks about recommendations for time tracking / invoicing software

@ismashpahone recommended actiTIME @cdstamper recommended Billings @ismashphone also recommended Marketcircle Billings @parrots and @wild37 recommended Harvest

@ismashphone shared a link to WatchAware (, with interactive previews of upcoming watch apps and general news about Apple Watch.

@zorn shared a link to iOS Coaching at thoughtbot

@needanadult: “I don’t suppose you have a good android emulator for iOS?”

Code Help topics

@needanadult shared a link about Swift crash tracking

Several developers had a long discussion of asynchronous calls, threading, and which threads should handle certain requests. It’s all too much to summarize here, but if you’re interested in the issue, check out the code-help channel for good dialogue.

@benss started a discussion of Cocoapods + Swift. Must use the latest Cocoapods version with Swift support (0.36.x).

Off-topic, um, topics

@zorn, @bendi, and @tompiarulli <3 React.js, or at least in theory…

@parrots asked for web host recommendations for someone wanting something between managed and VPS, with little to no sysadmin responsibilities.

@andrew uses Digital Ocean with Docker to help with snapshots. Also recommends GitHub pages.

@tompiarulli recommends Forge for static hosting.

@andrew shared a stealth post by @tompiarulli (not really):

@ismashphone shared an article about how Slack got popular:
