Hot Code Swapping in Xcode?

Question

I am doing iOS game development using the cocos2d framework, and I tremendously envy the ability for Eclipse Java programmers to hot swap their code while they are debugging

Answer 1

You can hot swap a variable value in Xcode by:

expression = ;.

By having a break point in the place where you wanna change the value and doing the command in Xcode console.

Example:

// Messages From Console
(lldb) expression graphFlag = @"X";    // Update variable value
(__NSCFConstantString *) $0 = 0x36f95718 @"X"  // Xcode prints the updated value
(lldb) expression graphFlag; // Printing value through expression command
(__NSCFConstantString *) $1 = 0x36f95718 @"X" // Hot Swapped variable value
