The same can be said for if/else constructs though— all those braces get heavy
if they’re all wrapping one line each. Python does away with the braces and
relies on indentation, but Swift has explicitly stated that it will not follow
that path— yet case statements seem an exception. It’s a collection of
statements, they should be grouped in braces.
Your example is still only one line per case, but those braces are less of a
problem when amortized over more lines (note that there are extra braces
enforced by the `if` and `else`):
switch x {
case 0 {
//a comment or two describing what's happening in this particular case
//because commenting is good practice
result=runSomeCode()
if result {
//do something here
}
else {
//maybe some more stuff
print(0)
}
}
case 1 {
//a comment or two describing what's happening in this particular case
//because commenting is good practice
result=runSomeCode()
if result {
//do something here
}
else {
//maybe some more stuff
print(1)
}
}
case 2 {
//a comment or two describing what's happening in this particular case
//because commenting is good practice
result=runSomeCode()
if result {
//do something here
}
else {
//maybe some more stuff
print(2)
}
}
default {
//a comment or two describing what's happening in this particular case
//because commenting is good practice
result=runSomeCode()
if result {
//do something here
}
else {
//maybe some more stuff
print(0)
}
}
}
