I tested same code 2.3 is fine

[danielgindi]

Yes but have you tested on 3.0? 2.5 is pretty much outdated. How do you even manage to still compile for Swift 2? You need to update your Xcode...

[billxie1988]

my Xcode is 8.3，OK I‘m going to try 3.0

3.0 is OK，but We need to stuff quiet a lot things on adaption. I still want to know the reason why cause this problem. Or is there any trick way to avoid this problem.Thanks
