Have you already use Do-While-False in some project ? This is of course not much applicable in Swift as we have guard let, but in C++, Java or ObjectiveC, this could be very useful in some cases. Let me past an example I found in old project. The purpose of the function here doesn’t really […]
Let’s take an example. You are working as a team, with 4 members (Alex, John, Michael, Henry). The team is working on 4 iOS projects (Calculator, Tetris, Streaming App, Social Network) Now we want to mark which team member is working on which project. A simple way would be to use enum for this. One […]
This is going to be the last post of the Swift Package Manager Series. After we create a package, then make it automated, and include it in our project, we would like to make a second package. And we would like the package A to depend on packageB. What we want Package A Package B, […]
Now that we know how to create a package hosted in a git repo and use in a client project, we would like to try to set up some automated build + running our unit tests. This would prevent any wrong commits, and we could be notified automatically by the system. For the example, I […]
In the first post, we saw how to create a package, here we’ll see how to use our newly created package without our project. Add code to your package First, open your xcode project, and create some code. Get rid of the automatically generated code : FluentCoding_MediaControl.swift Create a new swift file: MediaControlManager.swift ⚠️ Please […]
Today I would like to write about Swift Package Manager (SPM), which was introduced already several years ago, but I’ve never had a chance to try as I was mostly using Cocoa Pods for managing dependencies. I will split my experience over several posts (4), because there is a lot to write, so this one […]
What is a module? In Xcode we have the possibility to create modules like in other IDE/programming languages. Maybe you are aware of dlls in C++, or jar file in Java. These are self contained pieces of program (compiled or not) which are usually responsible for a main concept. You can imagine a module as […]
Swift UI has been around for almost 2 years now, and I didn’t have much time / opportunity to play with it. But yesterday I did my first Swift UI view. This is not very advanced, as I wanted to replace a simple table view which shows text on each cell, and handles a click […]
I like to write unit tests. It gives me early feedback on my code and challenge my design. After all, unit tests are the first clients of my API. Unit tests are cheap, easy to write, easy to maintain and fast to execute, at least they should 😆 Here I want to give just couple […]
How many TODO, do you have in your code? If your code base is big, or running for couple of years, I bet you have several dozen of TODOs in comments. And most likely, they are going to stay for a while. Usually we write TODOs like this ❌ TODOs got forgotten, unless you have […]
