Mobile Development Digest #57

The week full of news!

First of all, this was a week of 10 years anniversary of iPhone. Spend some in nostalgia with original press release for the iPhone and take a look how iPhone changed the industry (and one more).

Most shocking news was that two guys left Apple and joined Tesla. First is Chris Lattner author of LLVM and Swift Core Team member. Despite the fact that Chris leaves Apple he stays in Swift core team. This makes him the first non-Apple member. Ted Kremenek author of Clang will take his place. I believe that these changes will not affect Swift seriously and it will keep fast evolution pace in the same direction. However, it might be better to lower this speed?

Second is Matt Casebolt original Air designer. He worked also on MacPro and Touch Bar MacBook. I am worried more about this leave. Apple is my favorite device provider during past 8 years and as many others I’m not happy with what is going on with MacBooks and iPhone. If designers are leaving Apple then how it will affect the company? Obviously, someone new will come and it’s good because of fresh blood and new ideas. However, guys like Matt has a weight and they (probably) have a voice when top managers make a decision.

Design and performance were a key points of Apple devices. However, Windows PCs provide now much more variations and computational power than notebooks from Apple’s and Android phone aren’t far away from iPhone now; so my personal perception that device performance isn’t a key thing for Apple anymore. If Apple looses designers (I haven’t heard anything about Jonathan Ive while ago) then could it be a sign that focus moved to some point that completely different from what we saw in Jobs era? I hope not and decreased salary of Tim Cook can save a situation and return Apple to the way of innovations and unique, frontline devices.
