Xcode 3.2 Changes

These screencasts were based on Xcode 3.1.2. Xcode 3.2 looks a tad different in some areas, but generally all the shortcuts and power moves are the same.

A few notable changes:

1. If your custom macros stopped working Xcode 3.2, you’ll need to add OnlyAtBOL = YES or NO to each macro definition in your xctxtmacro file. Here’s an example from my ObjectiveC.xctxtmacro file (note the third line):

{
    Identifier = objc.property;
    BasedOn = objc;
    OnlyAtBOL = YES;
    IsMenuItem = YES;
    Name = "@property Definition";
    TextString = "@property (nonatomic, retain) <#type#> *<#variable#>;";
    CompletionPrefix = "prop";
    IncludeContexts = ("xcode.lang.objc.interface");
}

2. The LLVM/Clang Static Analyzer is now included as part of Xcode 3.2. To run it, simply use the Build->Build and Analyze menu item. The results are displayed in the build results window (shift-command-B).

3. In addition to using ctrl-. to select the next completion, you can now also use tab.

Have fun!

To clarify one thing about the “OnlyAtBOL = YES;” line…

From my tests, it seems that if you set it to NO, you cannot use completion for the item when it IS at the beginning of a line (beginning meaning the first non-whitespace characters). This had me a bit baffled as I was working through Mike’s great examples in the screencast.

Hope someone finds this helpful.

Thanks Robert yor remark helps. I’m using SnowLeopard and Xcode 3.2.1. My guess was that OnlyAtBOL stands for “only at the beginning of a line”. However I tested the macros below and the first one (called line) did work only at the biggining of a line. However the second (called hello) didn’t even though it says OnlyAtBol = YES;
In fact it only works when it’s not on beginning of a line. I relally don’t understand the logic behind this.

( {

Identifier = objc.line;
  BasedOn = objc;
  IsMenuItem = YES;
  Name = "Line";
  TextString = "// -------------------------";
  CompletionPrefix = "line";
  OnlyAtBOL = YES;
  IncludeContexts = ( "xcode.lang.objc" );
},

{
  Identifier = objc.hello;
  BasedOn = objc;
  IsMenuItem = YES;
  Name = "Hello";
  TextString = "Hello, Xcode!";
  CompletionPrefix = "hello";
  OnlyAtBol = YES;
  IncludeContexts = ( "xcode.lang.objc" );
},
)

Would it be possible to put some sort of text overlays in your instructional videos to say this? (i.e., something like “In Xcode 3.2, make sure to add OnlyAtBOL=YES”, or something along those lines. Or maybe a URL to check out.)

I’ve spent nearly an hour trying to figure this issue out, when in fact the video wasn’t telling me the right info. (Otherwise, your videos are excellent.)

Thanks.

When Apple releases a new version of iOS they often seem to also include some small fixes and enhancements in an update to Xcode. The release of iOS 4.2 was no different in that it was accompanied by Xcode 3.2.5 One minor change that I think is worth mentioning is the ability to set the base SDK to the “Latest iOS” version. Usually after an SDK version update you need to manually update the base SDK version of each project. The first time you open an existing project after upgrading Xcode will complain that it cannot find the base SDK. With Xcode 3.2.5 you can go into the project settings and specify the base SDK for all configurations to be the latest iOS version.

Thanks for code Noah, it really helped me out. My coding skill are pretty poor.

...moderator cut…

I’m happy that is working tab key now...

The first time you open an existing project after upgrading Xcode will complain that it cannot find the base SDK. Thanks.
