Let me share my story about a bug, which was driving me crazy for a week. I made some modification in my app, tested it on simulators, even a device, and I sent the latest build for the internal TestFlight. When I installed the app on the same device I used to use for testing ...
Ok, you might be laughing at the end of this post, but I thought it is better if I put this into a searchable form, and you might in the same situation as me. In a nutshell: I modified the signature one of my class’s initializer, this class was actually a subclass of the UIView, ...
The recent meltdown of GitLab made me more aware again about the remote repository and thinking about using more than one provider in git, with only one push. In a pure git based situation it is quite easy, actually you can use hacks and official solutions. Let see quickly what are they: Hack #1 At ...

In the first post I put the focus on the initializers, in this post I would like to put the nullability into the spotlight. I would also explain why is it a good practice, and how it will help you migrate your existing Objective-C code into Swift. Nullable/Nonnull The idea behind using the nullable/nonnull keyword ...
Let’s talk about the header (.h) files. Probably you know that what is defined in the header file has a public visibility. Any method or property declared here can be accessible all of the other classes, which are importing this file. That is one of the reason why we need to plan carefully what is ...
In the last post we changed the communication between our classes to be based on the Key-Value Observation. As we could see KVO is not the best solution for our problem, but sometimes can be helpful, if we need to observe one particular object property changes.
