As it turns out, learning TCA might be easier than you think!

I’m sure you’ve already used the search feature in Xcode.

But did you know that it has a hidden feature?

If you have some experience with iOS, I’m pretty sure you’ve already used a DateFormatter or a NumberFormatter.

For subscription apps, the paywall is very important because it’s basically the salesperson of the app.

That’s why such apps spend a lot of time trying to optimize their paywall as best as possible: the better a paywall is, the more revenue it generates.

Have a look at this function: func f(_ closure: (() -> Void)? = nil).

Would you say that the optional closure is escaping or not?

Last week I’ve told you about the advanced features of breakpoints in Xcode, and this week I want us to stay on the topic of little-know features in Xcode!

This time we’re going to talk about multiple cursors and how they enable us to quickly edit repetitive pieces of our code.

Nobody wants to spend their day adding breakpoints here and there, to try and piece together the reason why something is not working as it should.

So I want to walk you through the advanced features of breakpoints in Xcode: this way the next time a sneaky bug comes along you’ll be well equipped to track it down fast 😌

Memory leaks can cause a lot of damage and they are often very hard to fix 😔

That’s why I want to show you a nice little trick that will let you write tests that can detect memory leaks!

Have you heard of a new feature of Swift called Parameter Packs?

I want to show you a use case where they really shine!

SwiftUI feels like a pretty safe approach to build your app’s UI, doesn’t it?

But did you know that a small syntax error has the potential to completely crash your entire app?

Last week I’ve released a video that I was really excited about, because it focused on a topic that I had never really covered on my channel until then: How to optimize the performance of iOS apps!

The video was received very positively, so I figured that it could be worth it if for this week’s email I wrote an outline of all the tricks!
