Really? Knowing Apple they will be ditching Objective C completely within three years. I wouldn't be surprised if this was the first step in moving to ARM CPUs. (Well, that's an educated guess on my behalf but it could be true with A8/A9 CPUs, Metal coding and whathaveyou.)

Moving to ARM or MIPS CPU's?

Well it will be Apple's own. It's only me thinking out loud. I don't even know how an A8 processor would compare to Core i7 for example.

Point well made. The benefit we'll see is that if a developer prefers using ObjC but requires implicit typing in a particular part of the project, they can just switch over to Swift for that specific function and it will still be compatible with the rest of the project.

I believe there is type casting similar to PHP so it sort of fixes some of the void of strong type e.g. point out what type a variable should be.

I think if the speed of Swift is true then a lot of developer would move over to for the gains they can make, it also doesn't seem to have pitfalls such as seagfaults but that needs to be seen, just going through the ibook briefly.

Does the iBook teach you from scratch?

Thats my 2008 alu macbook screwed. It won't be able to handle OSX Yosemite's use of gpu for transparency etc, though I doubt the machine will be supported full stop.

It'll be fine - the GeForce 9400 runs Windows Aero well. Even decodes VC-1, H.264 fully in hardware. Might not have tons of shaders for playing games, but it's enough for desktop usage.

The latest iBook for Swift expect you to have some OOP programming knowledge I believe but give it a read.

Hmm I don't know. I don't play games full stop on my MB full stop but it certainly is a bit slower on Mavericks than previous OS's - I notice far more HD accesses.

Then again I have never ever reinstalled an OS from clean since I bought it

So since Snow Leopard I've done OS upgrades all the way upto Maverick

Had a bit more of a read now, and a quick play with a demo project based on Swift in Xcode 6. Waves of C# nostalgia were flooding back to me

You can still explicitly declare types if you want to, it is optional. Same goes for semi-colons, the compiler just ignores them.

Seems a step in the right direction all round really.

Yup looks very nice, not done C# so it reminds me heavily off Javascript.

I'm not so sure... Whilst the machine may be capable... Apple has a way of disabling certain features off certain models (airplay monitors for instance). The plus side is that he'll prob be able to upgrade but might not get the full package.

MagicBoy · 4 Jun 2014 at 10:01

The 9400 has feature equality and isn't far off the performance of the Intel 3000 which is the lowest common denominator for later 2010-2012 era Apple kit. Current Core Image accelerated apps like iPhoto run just fine on it. If they were going to drop support it would have been with Mountain Lion.

shiver · 4 Jun 2014 at 10:29

I hope they'll have the option to disable some of those UI features

MagicBoy · 4 Jun 2014 at 11:46

Airplay Mirroring leverages Intel QuickSync, which requires a supported CPU so it's an atypical case.

ic1male · 4 Jun 2014 at 11:54

I had a very brief look at the Swift book but I don't think it teaches you any of the Cocoa or Interface Builder stuff. So where do you learn about those?

Found this linked off the Yosemite thread :

Just a quick note to say that the new beta of OS X Yosemite looks interesting and runs well even on an old Macbook 5,1, albeit one with 8GB of RAM and an SSD.

MacBook 5,1 is the late 2008 alu model originally mentioned. Screenshots show it running full transparency.

Kainz · 4 Jun 2014 at 15:45

oooh, I has the 2008 Alu MB. Though it has the original 4GB of ram and a the stock 250gb HD on it. Good news overall if it does run well, at least when backed up by an SSD.
