What is debug build in IOS?
Debug builds of an application place debug symbols inside the compiled binary file by default, while release builds of an application place debug symbols in a debug symbol supplemental (dSYM) file to reduce size. of the distributed application.

What is #if #endif in Swift?
Perhaps the most widely used Swift compilation directive is the #if command, which allows us to conditionally include or exclude certain blocks of code when our program is compiled. For more information on using function flags, both at compile time and at run time, see “Function flags in Swift”.
How do you define debugging?
Definition: Debugging is the process of detecting and removing existing and potential bugs (also called “bugs”) in software code that can cause it to behave unexpectedly or crash. To prevent malfunction of a software or system, debugging is used to find and resolve bugs or defects.
How does the Python debugger work?
Python has a built-in debugger called pdb. It is a simple utility with a command line interface that does the main job. As soon as the interpreter reaches this line, you will receive a command prompt in the terminal where you are running the program. This is a general Python prompt, but with some new commands.
What are debugging symbols in IOS?
Debugging symbols are additional information about your source code that are used to aid in debugging. Also see this wikipedia article on debugging symbols. They will not be submitted to the app store as they are only part of the debug build, whereas you only submit a release build to the app store.
How do I know if I debug or release Swift?
As of Swift 4.1, if all you need is to check if code is built with debug or release configuration, you can use the built-in functions: _isDebugAssertConfiguration() (true when optimization is set to -Onone)
When you use ifdef debugging what is it for?
If so, what is it for? #ifdef DEBUG or #ifdef _DEBUG are used to handle some code that you use for debugging purposes. If you add #undef _DEBUG or similar to the beginning of your code, the compiler will skip the code contained in #ifdef DEBUG /* blah blah */ #endif.
When to use ifdef in a development environment?
Don’t make it any harder than it absolutely has to be. Use #ifdefs as sparingly as possible. In general, there are ways you can do this within your development environment for permanent differences, like debug/release builds, or for different architectures.
Is it safe to use ifdef in C++?
Using #ifdefs like this makes the code very difficult to read. So no, don’t use #ifdefs like that. There can be tons of arguments why not to use ifdefs, for me this is enough. All depending on what approaches are defined or not.
What does the ifdef keyword do in Verilog?
The `ifdef keyword simply tells the compiler to include the piece of code until the next `else or `endif if the given macro called FLAG is defined using a `define directive. `ifdef < FLAG > `endif `ifdef < FLAG > `else `endif `ifdef < FLAG1 > `elsif < FLAG2 > `elsif < FLAG3 > `else `endif
