iOS-XCode调试

Question

while i'm debugging my app there is some strange things. In some point the code line isn't be debugged one under another. Example :

LINE 1
LINE 2
LINE 3

Sometimes LINE 3 is debugged and then Xcode return to line 1 and proceed normally with line 1, 2 and 3. I hope i explained the problem well. Thanks

一种可能的解释是，优化编译器会对代码进行重新排序，以提高缓存的一致性，避免流水线停顿和其他麻烦。
