Apple has really lost focus on quality under Tim Cook. It's subjective but if someone were to make some site you could submit all sorts of glitches, the Mac guys who used to poke fun at Windows 10 years ago would have been in for quite a treat.

This is so true:

<cite> Apple's software quality is constantly degrading, especially last few years. I am sure I am not the only one who can see this fact. </cite>

While I agree that Apple's software quality could be much better, I really don't understand why bring this up with Xcode 9. Xcode usually has been really annoying pain in the ass, however with XCode 9 I have noticed nothing but improvements.

Build times are faster, cleanup times are faster, wireless debugging, new nice menu with cmd + click, no bugs so far etc.

The bugs he mentioned, are nothing but small fry. The guy is obviously overworked or something.

Xcode could always be better, sure. But personally I'm having fun coding this and that in Swift 4.

Do you remember an XCode acceptable on its first version, because I don't and I am using them since XCode 4...

Tell me which one is acceptable?
