I'm very used to option clicking on something in XCode, and then clicking the "notebook" icon in the top right, to bring up the appropriate documentation (see the image below).
Where has this icon gone in XCode 4.5? (i.e. how do I get to the documentation in 4.5?)
If you click on the link in the reference section of the popup, it will take you to the documentation section of organizer. I'm not sure if this is what you are looking for as I have never used the feature pre 4.5. Just tested this on my computer and it worked though.

I'm building my first application using CSS Grids.
Using Firefox's DevTools, I'm able to to highlight the Grid's tracks by clicking "# grid" next to an element in the "Rules" pane :
But when I click the "Layout" pane, it always shows "CSS Grid is not in use on this page":
Why is that?
(I'm using the latest Firefox version available today, "62.0.2")
UPDATE: Here's an example project.
UPDATE 2: It does work when I create a new, fresh, profile! But it doesn't work with my current profile, even when I start in safe mode, with all add-ons disabled... I guess I'll customize a new profile!
I agree with you indeed this is a bug in Firefox, I'm using the latest version of developer edition 85.0b9, I faced the same issue. You can clearly see, I've display as Grid still it says CSS Grid not in use on this page.
Issue - It happens when you open it in the default or the 1st Tab, it's not setting some tab-value there. The bug is still not fixed by Bugzilla's dev team, open from past 2 years. Let's hope they fix in future.
Issue Link - https://bugzilla.mozilla.org/show_bug.cgi?id=1492370
Solution - Just duplicate your tab, it'll work like a charm.
I was about to add a new app icon in Xcode 4.3 when I accidentally clicked something in the project inspector (the joys of using the touchpad and not a mouse). I had my project selected and was about to add a new image for iPhone retina icon when I accidentally selected something and now I cannot see anything of my project. The last thing I remember seeing was a drop-down menu change to "Absolute" (I think as I only saw it for a moment) and I think the label was something to do with paths. The screen flashed and the entire project disappeared from the Xcode UI even though it is open.
The folder created in my Documents folder by Xcode is still in tact and all files are present. Even opening the project from here renders the same result - a completely empty Xcode except for appdelegte.h and .m.
I have even tried restoring an earlier snapshot but it does not help. When I open my project all I see is the AppDelegate.m and .h and nothing else. The only item in my project navigator where I used to see all my files is my app name .xcodeproj in red text. I cannot find anything to help me get my project back.
Can anyone help me to reverse this simple mistake?
I was able to reproduce this problem consistently and cause Xcode to crash in the process.
1] Start Xcode (Quit and re-start) and create a new utility project named TestProj. I don't believe the project type or name makes a difference but I didn't try any other combinations. Do not create a GIT.
2] After the project is created, simply click on "Location" which is greyed out because the project is selected in the project navigator. Once you have done this, the project is hosed and you can't get the project to open in project navigator again - it simply shows "TestProj.xcodeproj" where the project used to be listed in the project navigator.
3] To see Xcode crash, selected "Relative to SDK" and Xcode dies.
I have accidentally clicked on that greyed out location twice simply due to my apparently terrible mouse skills.
Apple, please fix this!
After reading:
Accidentally changed location of project file in file inspector, now can't see any project files in Navigator.
I went to Xcode (4.3 on Lion in my case), selected the project on the Project Navigator (left Xcode panel) and in the File Inspector (right Xcode panel) I updated its location to the Relative to Group value and then clicked over the little image button (underneath the location line) and selected my project.xcodeproj from Finder. It also solved the problem.
Best regards.
Ok - problem solved.
Eventually Xcode opened without crashing and with a seemingly useless file listed on the left in the navigator. I highlighted it (which is when Xcode was crashing all the time) and immediately clicked the in the project name text box in the inspector and entered my project name. Then selected the drop-down beneath it and selected relative to SDK. As soon as I let go (mouse-up) it changed to "Not Applicable" and my project re-appeared. Happy days! Only lost a day worth of work - but could have been worse...
Thanks to everyone who gave this some time...
I haven't been able to find what these Xcode icons mean. Some you can deduce (cup icon is cocoa, person icon is your code) but other's are more mysterious.
UPDATE 1:
I was able to find the icon files under:
.../Xcode.app/Contents/PlugIns/DebuggerFoundation.ideplugin/Contents/Resources
There's a total of 13 different icons and they are all clearly labeled. In the screenshot that I posted we have:
Person icon is User
Mug icon is AppKit (or UIKit)
Briefcase icon is Frameworks
Gear icon is System
Morse code icon is Foundation
Spider web looking icon is Web
Update 2:
A while back I wrote a blog post that's easier to read:
http://jlmendezbonini.com/2013/03/27/Xcode-4-debugger-icons.html
Update 3:
Looks like Apple finally documented it in the Process View Display
section. Here's a link to the image:
Here's a quick screen shot of the folder mentioned. The names explain the meaning of each icon. This is from xcode 5 beta 2.
The icon means, in general, assembly for which you don't have debugging symbols. Not your code (the person icon), not public, top-level Cocoa code (the mug), not Framework/library code (the suitcase) but plain old assembly.
I don't think this is documented anywhere (I haven't seen it) but it seems to hold true for all the tests I've done.
Running Analyze in Xcode 4.0.2 shows issues in the Issue Navigator. Clicking on an issue makes the appropriate file appear in the Editor pane, but nowhere does it show where in the code the issue occurs as I am used to from Xcode 3.x. Does anyone know how I can turn on this feature?
A couple of tips:
First, if you're looking for the view where Xcode annotates the project with arrows, bear in mind that you may need to expand the top-level analyser result in Xcode's Issue navigator and click the second-level issue in order to see those - see screenshots.
Screenshot 1: top-level issue selected - no arrows
Screenshot 2: second-level issue selected - arrows!
Second tip: if that stuff isn't working, try cleaning the project's build products folder. Hold down the Option (alt) key and choose Clean Build Folder... from the Product menu. (You need to hold down the Option key, otherwise you won't see that menu option.)
I've seen this happen before sometimes. I believe it's a bug in Xcode. Restart Xcode and try again.
One note. I'm seeing this for files that are referenced outside the current project. I currently have a library in which the files with missing annotations live and simply added them to my current project without copying them. Haven't done the project dependency setup yet, so if you're referring to files outside your project that could be why. (I opened the library project, did an analyze and the annotations showed up.)
Woohoo, I've nailed it! At least for me. I've been struggling with this problem for about 2 hours now, trying out all the things suggested here and more (Xcode 4.0.2, Snow Leopard). Bizarre thing was I had one file where the warning were correctly showing in the editor. Then I noticed the difference to all other files; in the File Inspector pane the location was specified as "Relative to Project" (warnings show correctly in the editor), all the other project files were "Relative to Group" (warnings not showing in the editor).
I took one of the problem files, switched it's location to "Relative to Project", reanalyzed and bingo! I've see it's warnings in the editor.
I guess this ties in a bit with David Goodine's answer refering to files outside the project.
I am working on Struts project using the Spring Source Toolsuite IDE.
When there are complier errors or something, a red X mark or yellow exclamation mark appear over the icon for my project.
But even after I made sure there are no complier errors, I got this exclamation mark in my project icon. My project is building and running successfully and I am getting the proper output.
Why is it there? How can I find out what it is complaining about?
Click Window -> Show View -> Problems and you'll see the list of errors/warnings and you can take it from there.
As ptsw pointed out, too:
If the Problems item isn't visible in Window -> Show View menu, choose Other... instead and select Problems in the General group to view the Problems pane:
