You can also do "expression -l objc -O -- [`self.view` recursiveDescription]" if you've hit a breakpoint inside a UIViewController. The "`self.view`" is Swift code, the rest is Objective-C format. Idk why KZitem is adding a strikethrough format but it's dash l and dash O.

Great video! Hands down one of the best video I've seen on LLDB (believe me I've searched near & far :) ). Hopefully, you can make another more detailed follow-up video for advanced debugging too - with specific focus on detecting/debugging constraint issues.

If you want very in-depth and more descriptive information that you didn't even know exist, I recommend watching the Apple WWDC debugging videos, especially since 2018 it's still relevant.

Always love your video, I have to mention that your code and tutorials are basis of my first iOS app that I am still working on. Would also appreciate it if you can share more insights about different architectures, specifically, I heard about TCA, while I developed my app in MVVM (UIKit + SwiftUI + Combine). Some people mention that SwiftUI should not be using MVVM.

thanks for this useful video! it's only me thinking that Xcode's debugger is the worst thing ever? all the time when i'm trying to debug something he doesn't know what i want from him or what to do. i always get errors like: error: expression failed to parse: error: Couldn't realize type of self. or error: expression failed to parse: error: :2:11: error: cannot find type '$__lldb_context' in scope extension $__lldb_context { ^~~~~~~~~~~~~~~ even for the simplest code, it doesn't understand what I want from it and it's very frustrating. i can't believe the apple have such a bad product.

Hi Brother, Hope you are doing well. I have a request. I recently tried to learn about iOS login Authentication and how it works while you have a sign in option in your app and under the hood how to pass the token, where to store and how the mechanism works. I encountered this questions a lot overtime. When you get chance, please create a tutorial on top of it please please. Thanks a lot.

runtime injection can be really useful as well as symbolic breakpoint. Can we use symbolic breakpoint for variables? If not then whats the alternative for watch var in Xcode and how to use it.?

Great video. To avoid typing in long commands in lldb it's pretty simple to create an alias in .lldbinit. Looking into FB's chisel is also worth it it has a lot of useful stuff, ie. the print hierarchy is simply "pvc"
