In an Objective C project for MacOS using XCode 12.3 I define variables of various types including NSRect and CGFloat at the start of a class implementation region so that they are accessible from all methods. When I add a breakpoint in a method, some of the variables can be displayed by hovering the cursor over the variable in the code window or examining the variables window. However, some class-level variables are not shown in the variables window or by hovering over them. Attempting to examine then using po in the debugger console shows an undeclared variable error. Class-level variables of type CGFloat which are assigned are visible but not variables that do not have values assigned. None of the objects class NSRect appearing on the RHS of assignments are visible when hovering over the or by using po in the debugger console.
