How to fix iOS crash "EXC_BREAKPOINT UNKNOWN"?

Question

I have in my app this type of crash:

Line 144 is this:

if singleProfile == true

And variable declaration is this:

var singleProfile: Bool = false

I really don't understand why it crashes :(

Answer 1

I have seen EXC_BREAKPOINT UNKNOWN happens when you are unwrapping an optional but the value inside is nil. Please check unwrapping optionals code.
