Execution was interrupted, reason: internal ObjC exception breakpoint(-10)..

In debugging mode, getting exception while evaluating expression for mostly all custom framework functions.
error: Execution was interrupted, reason: internal ObjC exception breakpoint(-10)..
The process has been returned to the state before expression evaluation.

(lldb) po <function with parameters>
error: Execution was interrupted, reason: internal ObjC exception breakpoint(-10)..
The process has been returned to the state before expression evaluation.
(lldb)
Could you show the code where it occurs ?
Can't show the exact code.As the break point hit the function, I am trying to change its parameter value in debug pane like below:
(lldb) po someVar
"ABC"

(lldb) expression self.someVar = "XYZ"
() $R4 = {}
(lldb) po self.someVar
"XYZ"

(lldb) po methodName(with: self.someVar)
error: Execution was interrupted, reason: internal ObjC exception breakpoint(-10)..
The process has been returned to the state before expression evaluation.
(lldb)
