Our Featured Part

DTPinLockController

New version 2.0 now fully supports iOS 5 through iOS 8 on all iPhones and iPads.

Just like the passcode lock mechanism of the iPhone, you can allow your users to set a 4-digit PIN for your own app. Then when starting your app’s personal data will only be available to the user.

It mimics the animations of the original for entering and confirming the PIN.

Available on the Parts Store

Our Featured App

Available on the iPhone App Store

Big red LED digits allow you to see the timer even at great distance so you are free to move while you give the talk of your life. SpeakerClock emulates the famous countdown clock that all speakers at TED conferences need to adhere to.

The latest version is a universal app with HD-support for iPad, multiple presets and lots of usability enhancements. New portrait support allows you to put your iPhone/iPad in the cradle and still use SpeakerClock. Now the whole screen flashes if you transition into a new phase of your speech.

Radar: [Xcode] Enabling Extension-safe API check changes generated ObjC-Header

Normally you only need the “Allow app extension API only” for extension targets, to get warned if you are accessing API which is not available for extensions. I had enabled it for a framework to make sure I didn’t call forbidden API.

I found this issue at the same time as this other issue because my client complained about both problems: Not seeing any documentation via Quick Help as well as the generated header unnecessarily containing internal classes. This problem was already present in Xcode 8, as evidenced by somebody asking about it on Stack Overflow.

Radar: [Xcode] Quick Help no longer shows documentation from imported module

I found this new issue when developing a framework for a client. I have all Swift code in a module and added nice documentation comments to all of the public methods and properties.

In Xcode 8, you could Open+Click on any property, class or method and you would see the documentation from these comments. This would work regardless if you are in Swift or Objective-C code.

Now with Xcode 9 that suddenly doesn’t work any more from Objective-C code. In Swift files it still works, both in the module itself as well as an app importing it.

Back to Square Two

When I started blogging on Cocoanetics.com in early 2009, I had been dabbling with iOS development for little under a year. That was the same time when I turned full-time, when my prior employer decided to have someone cheaper doing my job (Windows PC Helpdesk). This initial blogging frenzy was the way most of my clients found me, both for components as well as custom app development.

Who is Cocoanetics?

The word Cocoanetics comes from the words Cocoa (the framework we use to program iOS apps) and Genetics (to build, make up). It simply states that we have living and breathing iOS development a level even deeper than “in your blood”.

Our apps and parts are often experiments, mostly pieces of art, but always carefully handcrafted. We’re still learning and getting better at coding every day. You benefit from this because our code gets better all the time and we share what we learn on our blog.
