So here lies the bug - I have a controller named NameSelectionController. In order to do that, let's run the code, execute anotherMethod 4 times in a row and see ourselves that it eventually prints True in the console. Why? Now we know that this line of code when added to the initializer works, we can safely modify the initializer of NameSelectionController to include that line, Update: I realized it later that we don't always need to do it this way. This is complete garbage. This is interesting because last week I came to know about the fact that Swift's inbuilt, Public speaking, Thus if you run the code again and this is the only symbolic breakpoint you have, you can see console prints algo without stopping or pausing the program execution. My intention is to use this post as a reference for the future debugging session by having one place to get the list of all tricks I learned from this it. To move the Instruction Pointer, just click on Hamburger icon on the right and drag it to the desired location. This is called an Instruction Pointer and it points to the next line of code to be executed. However, this could be hidden somewhere in the app, and the problem might seem gigantic when considered a huge project size. Now we will see the demonstration of another trick which allows us to hit the breakpoint and find the source of execution when the given method is executed. We will add another symbolic breakpoint in our program execution. Another opposite trick you can do it to avoid the line of code from executing. So say, I am paused at the above-mentioned breakpoint, I can easily verify these parameters using following debugger commands, Please note that I had to cast arg2 to SEL since lldb doesn't know what kind of type that arg represents, Please note that since this code gets called every time setText is called on UILabel, this might trigger false positive. So let's make an alias called poc for it as follows. $4,200.00 excl. In Advanced Apple Debugging and Reverse Engineering, you’ll come to realize debugging is an enjoyable process to help you better understand software. Calling this method with alternate parameter through debugger with expression, Moving the instruction pointer to the next line and finish the execution. Advanced iOS. Fortunately, for iOS developers though, Xcode and Core Foundation provide some advanced networking debugging tools to help you gain insight on network traffic from the client vantage point. Tip List First, we will call outerMethod and put the breakpoint on the line 121 as shown in the image. Suppose I want to find the recursiveDescription of a given view. Let's see how it can be used to call the same method repeatedly without having to compile the programme every time. However, there is a bug which I uncovered during the debug session. It’s easier to enable USB Debugging on Android with no software hiccups; however, it’s entirely different for locked phones. Let's assume we have these two methods named outerMethod and innerMethod. The tips in this article should work in Visual Studio 2008/ 2010. Speaking, Suppose I have the following method named anotherMethod.
