When converting a project to use ARC what does “switch case is in protected scope” mean?

Question

When converting a project to use ARC what does \"switch case is in protected scope\" mean? I am converting a project to use ARC, using Xcode 4 Edit -> Refactor -> Convert to

Answer 1

For me, the problem started on the middle of a switch and curly brackets did not worked out, unless you have to include {} IN ALL previous case statements. For me the error came when I had the statement

NSDate *start = [NSDate date];

in the previous case. After I deleted this, then all subsequent case statement came clean from the protected scope error message

Answer 2

Surround each case itself with braces {}. That should fix the issue (it did for me in one of my projects).

Answer 3

Hard to be sure without looking at the code, but it probably means there's some variable declaration going on inside the switch and the compiler can't tell if there's a clear path to the required dealloc point.

Answer 4

There are 2 easy ways to solve this issue:

• You are probably declaring variables. Move the declaration of the variables outside the switch statement
• Put the whole case block in between curly brackets {}

The compiler can not calculate the code line when the variables are to be released. Causing this error.

Answer 5

Surround with braces {} the code between the case statement and the break in each case. It worked on my code.

Answer 6

Declare the variables outside the switch, then instantiate them inside the case. That worked perfectly for me using Xcode 6.2
