My question is, will they release XCode 4 for 10.5, or only 10.6? I already had to download the iPhone dev kit version of XCode after a system wipe because the standard version of XCode is now 10.6.x only.

My mac is a MacBook Air RevA, and there've been some negative reports (maybe ironed out by now) of issues with 10.6 on the older MBA hardware, so I have avoided updating.

I imagine it will be 10.6 only based on what Apple has done in the past.
 
You can't judge it on those screenshots, there are too many good bits they don't show.

I completely agree. Any concerns I may have had are gone.

It's killing me though that it's not available to download yet, and I'm not sure why Apple feels the need to NDA it. I think there were some legal issues which were behind the iPhone NDA stuff back when the iPhone SDK was first released, but I'm having a really hard time understanding the thinking behind NDAing Xcode 4 right now (surely it's not to hide the advancements from their competitors at this point?).

I think one of the most exciting aspects of Xcode 4, is that there are a lot of REALLY cool features that are now possible to add in future versions because of the major pluming work they've done under-the-hood.

Why would they release Xcode 4 for 10.5 when the current version of Xcode is 10.6 only?
 
Also, I would recommend watching Session 300 - Developer tools State of the Union. You'll get to see a good overview of new Xcode 4 features.

You can hear us Ooo'ing and Aaah'ing.
 
Does Xcode 4 offer anything competitive for people developing in Java, PHP, Python (or indeed anything other than a C-variant or Cocoa-variant)?

No. XCode is made for Apple's tools and libraries (Which if you haven't guessed, use mainly C languages). You want Java? Use Netbeans or Eclipse. There is no point in Apple wasting resources they don't really support or use.

While i love Netbeans for my PHP, Ruby and Java needs i would love to jump ship to Xcode for more than just C and Objective C. Perhaps plugins for other languages would be a nice bonus for 4.1.

Except for the fact that Xcode does support Python and Ruby for use with their respective Cocoa bindings which are supported by Apple.

In fact Xcode still (well at least 3.2.2 does) supports Java you just need to access the templates through the Organiser.
 
Clang is the compiler, which is based on LLVM. I've known about it for a while (the analyse feature in XCode 3 is really useful). The new debugger is LLDB, which is related to Clang, but is new.

http://blog.llvm.org/2010/06/new-lldb-debugger.html

Clang is more than just a compiler. It's also a set of libraries for doing compiler-related things like parsing, semantic analysis, etc... it can be used to build syntax colorers, code autocompleters, and other handy tools besides compilers and static analyzers.

I am also curious why it's not available yet to ADC Online (or whatever they're called now) members. Surely the reason is that either it's not ready (because of bugs that need fixing) or Apple's delaying it on purpose to co-release with the final iOS 4 SDK... or both.
 
For those disappointed that they do not have access to Xcode 4 yet, don't be too disheartened. I managed to get my hands on a copy and all I can say is that despite all the cool new features, its nowhere near ready for every day use yet. I've found it nearly impossible to get anything productive done.

Could you share? :cool:

I've had my antennae up on this issue as well, and from what I've heard, people are guessing a real beta version in fall at the earliest, with spring being a reasonable estimate for the final ship date.

I don't feel quite so bad, not having it yet. Although, Apple could have done a better job communicating with it's ADC members. I'm still baffled by the NDA, what a bunch of legal nonsense.

so it is really in a BETA stage. No release soon then ?
 
It's a developer preview. "Preview" with Apple seems to hint at an early tease. It's meant to make you drool and get excited about it, similar to the iPhone update previews Apple had in April.

I'm expect an official open beta to all ADC members within 2-4 months... Maybe even an official release. I'd love to see a beta released on Monday with the release of iOS 4.0, but that doesn't seem likely as they've had only two weeks to gather bug reports and fix things.

I've watched many of the XCode 4 overview/demo session videos from WWDC2010 and am very excited. Working with XCode 3.2 now makes me sad that I can't use the new features yet. I sometimes also find myself attempting to do something I saw in the XCode 4 videos within XCode 3.2 and realizing I can't do it yet.

I have seen the light . . .

Having watched the WWDC session 300 Developer Tools Overview, I am completely sold on the Xcode 4. Of course, that's the objective of the presentation, but everything looks great.
 
I really hope this new version of XCode's project builder has all the appropriate hud-style controls. Anyone got any insight on this?
 
... do you mean Interface Builder? That's more related to what AppKit has implemented than it is related to what Xcode provides. i.e. upgrading Xcode won't install additional AppKit controls on your system.

Just out of interest, what are you missing?

Right not with Xcode 3.2 its just not nice to work with and does not tell me how my classes link up, if a class is over written by another. Mostly silly little things that Netbeans is just great at.
