q
need to understand initializers
issue
use of undeclared type UIViewController
q
where can I get a short list of the required initializers
note
whenever swift gives a weird error you should first go to the documentation
q
nothing happening on screen.
is barButtons getting hit ?
q
which of the view controllers init methods is getting triggered ?
task
with a runtime error need to find where the error took place. First step is always an exception breakpoint
note
Whenever a runtime exception occurs the first step to solving it is to use an exception breakpoint.
q
In swift how to create a method that does not have named arguments ?
q
check if I can get ANY graph method to work
result
No. I created a method with nothing in it and it does not work.
q
If I create a graph variable within testGraph does it run?
result
somehow the build target got changed
other interesting ways that this bug can occur are given here
