Apple’s insistence on XCode for iPhone OS apps not about Adobe, but switching chip architectures?

"This week Apple confined developers to a specific set of tools (XCode)," Steve Cheney blogs for steve's blog. "A lot of people think this is to kill Adobe Flash. Sure, that is a tactical reason, but there are much broader strategic reasons. By telling developers to move to XCode tools, Apple is setting the stage to potentially switch architectures."

"History often repeats itself: In 2003, Apple advised developers to switch to XCode tools," Cheney writes. "This was not a coincidental move—2 years later Apple moved to Intel across its entire Mac line. Developers who complied could simply press a button and applications would run natively (full performance) on new Intel Macs."

"Now consider this - Apple may have already switched without people knowing. Here’s an anecdote - the innards of Apple’s A4 (powers the iPad) have been speculated ad nauseum by experts, but the reality is no one knows what’s actually inside. This week, there was very surprising analysis that the A4’s die size far exceeds what it 'should' be (single core ARM Cortex A8 with a 64 bit memory bus and GPU).

"This analysis is not yet mainstream, but will add tremendous fuel to the fire that perhaps the A4 is NOT an ARM architecture," Cheney writes. "In fact, it’s highly possible that the A4 is a dual core Power Architecture, which is what the PA Semi team worked with, prior to Apple buying them in 2007."

"If this is indeed the case, then iPhone OS 4.0 would bring incredible speed improvements to the iPad, since it would no longer run applications on an ARM processor emulator," Cheney writes. "Can you imagine if OS 4.0 improved the iPad’s speed by 50% on day 1? Apple would be heralded as a software God. But in order for these speed improvements to be realized, apps would need to be written in objective C—which is exactly what Apple is now telling developers to do."

Cheney writes, "We will likely find out what's really inside the A4 soon. But one thing is already clear: Apple is sowing the groundwork to make architecture changes seamless—developers will only need to flip a switch to give their apps blazing, native performance... I find it fascinating that Apple has been so good at diverting attention to the Flash argument, that people don’t see the true genius behind Steve Jobs' vision..."

Wow. This is good news. It certainly brings light on what I thought was a sh*t sandwich made by Apple.

I hope this is true.

EDIT: Why don't they just tell everyone this if it is what they are up to?
 
Now matter how you spin it, it is about apple's desire to shut out adobe/flash from the iPhone/iPad platform.

AFAIK, xcode isn't the issue, heck adobe could (has?) provide a xcode sdk/framework but since that's against the policy of apple, there's no way we can use them.
 
MR posted a news story on someone disassembling the A4[/URL] and determined it was very similar to the iPhone and likely the Cortex A8.
General consensus is that is a modified and/or crippled Cortex A8. Crippled in that it may have some Cortex A8 circuitry stripped out for size, speed and specific usage.
 
The article is highly speculative and seems a bit off the wall.

However, the author bringing up the Intel switch was interesting. I could see where Apple would not want a repeat of the Carbon/Metroworks Codewarrior problem.

Big developers including both Microsoft and Adobe waited until the very last minute to move to XCode, costing them months of not having a version of their software that was native to the Mactel platform.

If Microsoft and Adobe would have been on the ball, we might have got Universal versions of Office 2004 and Creative Suite 2 (but probably not for marketing/revenue reasons).

RUMOR: Next-gen iPhone to be powered by Apple A4-based chipset
Monday, April 19, 2010


"According to the Korea Times, which cites an anonymous industry executive, Apple will indeed discontinue its tradition of using Samsung-designed processors with its next iPhone," Kelly Hodgkins reports for The Boy Genius Report (BGR).

"In its place, the phone will run a modified version of Apple’s A4 processor which just so happens to be proficient in handling 720p playback," Hodgkins reports.

"It’s not a complete loss for Samsung considering it’s expected the electronics giant will be entrusted with manufacturing the chip, but no doubt Apple’s decision to keep mobile processor design in-house will effect Samsung’s bottom line," Hodgkins reports.
