Reducing the pain of git bisect with Xcode

Sun, 22 Jan 2017 11:49:01 +0000

There’s times when you need to investigate regressions in your project, and you don’t know have any clue as why something is happening. Git bisect is the best tool for this cases, but it can be painful to use in non small projects using CocoaPods and Xcode. I want to share what I’ve been doing to ease the pain.

Controlling time in the app

Wed, 26 Oct 2016 19:38:37 +0100

Today I want to share a small utility we’ve been using for a while at Peak, my current workplace, to control the system time inside the application and save time while testing or debugging.

Xcode 8: New build settings and analyzer improvements

Sun, 31 Jul 2016 21:50:16 +0100

I always like to check the new build settings and analyzer improvements of every Xcode release. And this year’s main release includes a couple of goodies. Let’s check them out!

Xcode 7.3 analyzer improvements

Thu, 21 Jan 2016 20:39:53 +0000

The latest xcode beta is available for downloading. There are many improvements, and the usual problems with stuff that stops working… Ah the love of Apple for it’s developers :). But I want to tell you about a feature that caught my attention: New analyzer settings!

New analyzer settings

From the release notes:

The static analyzer warns when nil is returned from a method or function with a nonnull return type or is passed to a parameter marked nonnull.

Transitioning iOS versions

Mon, 14 Dec 2015 20:00:25 +0000

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?

Three months with XVim

Thu, 19 Nov 2015 22:19:24 +0000

‘Know your key shortcuts’ is the mantra of the productive programmer. I’ve chosen to try using the same keybindings everywhere, investing time and learning Vim. And using xvim in Xcode. In this article I’m going to try to explain why I did this, and I’ll share my experience of the process.

Jumping into existing codebases

Sun, 15 Nov 2015 18:55:18 +0000

I’ve recently changed workplace - we’re hiring! - and I’ve jumped into an existing codebase. This is a good time to review what I like to do when I start to work on a project in these circumstances.

Freehand Drawing

Thu, 20 Aug 2015 21:09:40 +0100

Yesterday my last post on the series ‘Let’s build Freehand Drawing for iOS’ has been published at Badoo Tech blog. It’s been a very good experience for me, and of course I recommend you visit the tutorials if you are interested.

I divided the tutorials in 3 parts:

Part 1: Introduces the feature and a naive implementation
Part 2: Adds undo functionality, refactoring along the way
Part 3: Improves stroke to make it look smoother

Building tutorials is hard

This series has been my first take on writing technical tutorials. And I must say that it’s a lot harder than I thought. You need to keep track of the content, code correctness, and the pace of the articles so it’s readable and understandable. Coding while writing an article is challenging, but the experience has been very gratifying.

Adopting Objective-C generics

Tue, 09 Jun 2015 22:53:14 +0100

This year in WWDC, Apple introduced Objective-C ‘lightweight’ generics for XCode7. This builds upon the improvements to Objective-C to document the code and improve the interoperability with Swift. I wrote previously about nullability annotations and I continue to be delighted by these changes to the language. Here’s what I think.

Fragmentation

Wed, 27 May 2015 15:16:50 +0100

As an iOS developer or Apple-centric developer, WWDC is a time of excitement and news. The yearly event at Apple offers many networking opportunities, but most importantly sets the stage for the next year of development in the company’s platform. As this year event is closing in, I wanted to write my thoughts on a related, and often overlooked topic; fragmentation

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.

Code signing and distributing - Swift

Fri, 13 Feb 2015 11:45:12 +0000

Having problems code signing and distributing your application written in Swift? I’ve encountered some, found solutions for them, and I’ve written a sum up for Badoo Tech blog.

Hopefully it will help anybody with similar issues and increase discoverability of the solutions.

Swift Animations

Thu, 05 Feb 2015 20:00:14 +0000

Today I introduce a small Swift DSL to improve how complex and chained animation code looks, and reads.

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.
