In the Xcode breakpoints panel, it has a column of 'checkbox' (between Breakpoint column and Location column). My question is why some breakpoint has 'a Check' some has a '-' and some are empty? I think 'a Check' means enabled.
I have one breakpoint which I manually make it to 'enabled' (a Check) but as soon as I 'debug' my program in Xcode, it turns into a '-'.
