This is one of those community consensus things. Most of the style guides and Apple's own examples usually include the opening brace on the same line as the conditional or method.
The real 50/50 proposition is having else on a new line. Some people love that and some hate it. It was hard for me to know what the consensus is, so I picked one way and if it turns out to not be what the majority find correct, others can correct it.
Right, because is a community consensus thing, you wouldn't mark that convention as 'bad'. You could write that the same line curly brace opening is 'preferred'.
