How to change variables value while debugging with LLDB in Xcode?

Question

In Xcode, GDB allows you to change local variables while debugging (see how to change NSString value while debugging in XCode?). Does LLDB offer a similar functionality? If

Answer 1

The following stuff works for me. I am using Xcode 8.

If you want to set some variable (for example a "dict") to nil and then test the code flow, you can try the following.

1. Put the breakpoint properly after initialised to the desired value.
2. then execute "expression dict = nil" in lldb command line to change it. (for example "nil")
3. Step over the break point.
4. Check the variable "dict" in the next line. It will be nil.

It will look something like in the console.

(lldb) expression dict = nil
(NSDictionary *) $5 = nil
