Fixing autocompletion on mixed Objective-C and Swift projects

Fri, 16 Jun 2017 23:55:27 +0100

This year I had the privilege of attending WWDC for the first time. I knew the labs were very important, and I want to share a resolution to fix a problem for our big project at Peak: Autocompletion on Swift code was not working most of the time in the IDE, and with the help of an Apple engineer in the labs we got it sorted.

Update on 30/10/2017:

The issues described here seem to be fixed with latest release version of Xcode 9.0.1 (9A1004). Also the ‘internal’ menu doesn’t seem to be accessible anymore. If you know how to access it I’d love to hear from you!

Automatic bridging from Swift to Objective-C using Sourcery

Sun, 21 May 2017 22:30:00 +0100

I recently read a great post by Benjamin Encz about bridging Swift to Objective-C by creating bridging types that can be exposed to the older language. I wondered if his idea can be improved and automated using meta-programming with Sourcery by Krzystof Zablocki. The answer is a very impressive ObjC-like uppercase YES.

Transitioning iOS versions

Having worked in companies developing their own products, I’ve faced many times the problem developers encounter when building iOS applications: Your biggest 3rd party dependency - the OS SDK - is changing under you every year. How does your team deal with this in a maintainable way?

Adopting nullability annotations

Fri, 17 Apr 2015 23:39:03 +0100

Apple introduced nullability annotations to Objective-C compiler from XCode 6.3. I was really surprised by this change, and welcomed it with open arms when I saw the release notes. My first thought was: Objective-C is learning from Swift! I want to share my 2 cents on this new annotation and what it means for more modern Objective-C code.

A tale of categories and extensions

Sat, 20 Dec 2014 21:37:17 +0000

I’ve gradually been changing my code style favouring (Obj-C) categories and (Swift) extensions a lot more. I’ve been inspired by my other lover (Ruby). Why? Readability and code organisation.
