Have Xcode show breakpoint in Assistant editor if file is open - xcode

So I just got into TDD and working with tests I started using the Assistant editor a lot more. I usually keep my test file on the left and production code on the right. However, when running a test, if I hit an exception or a breakpoint in my production code, the file opens up on the right again, even though it is already open on the left.
My goal is to have Xcode focus on the exception/breakpoint in the Assistant editor if the relevant file is open right now. Is there any way to achieve such behaviour?
The closest thing I found was in the Behaviour tab in preferences where I can choose which editor jumps to the exception/breakpoint, but this should depend on which file did it occur in. So if there is a problem in currently open test file, show it on the left. If it is in currently open production file, show it on the right. If it is in a file that is not showing, then show it wherever.
Thanks

How to return window state back to normal after debugging

When I run my project in Xcode a few things happen (especially if there was an exception)
The debug (output) window slides up into view
The file directory pane on the left switches to the Debug navigator
The code file you left off on switches to main.m or some other file where the error happened.
That's all great, but when I'm done running the application none of this goes back to how it was. So that means there's this constant repetition of hiding the output window, clicking on the file directory icon, and finding the file I was just on.
This is just completely unacceptable as I may run the application a dozen times in a minute.
Coming from Visual Studio, the same experience happens when debugging, but everything returns back to normal when you stop debugging.
How can I make things return back to normal?
Assuming you're using Xcode 4 or later, you can set up behaviors to set up things how you want. Under the Xcode Preferences, click on the Behaviors tab and select "Completes" under the "Running" section. You have the option to open or close any of the various panes.
Here's an interesting article on customizing Xcode to make it work better for you.

Unable to set breakpoints in Chrome dev tools, version 26.0.1410.64 m

I need to debug some JavaScript an' I use Chrome dev tools. I'm a newby in JavaScript (just started to learn a couple of days ago), an' at work I could set breakpoints via the Resources pane. But at home for some reason I can't do this: after the click no breakpoint appeares.
I have Chrome version: 26.0.1410.64 m.
What could be the case?
clicking on the De-Obfuscate Source button (i.e. {}) solved this issue for me.
I'm a fool! haha! breakpoints are set in the Source pane )))
It's been a while, but in version 33.0.1750.146, but my problem was that I was on the Sources pane (I'd call this a tab; it's one of the items at the very top of the window), but I was on the Content scripts tab (on the left hand side). I needed to switch to the Sources tab.
To be clear, there are two sets of Sources tabs; one is within the other.
UPDATE 2016-01-07: Now I'm on 47.0.2526.106. The only thing that worked for me today was to close DevTools and re-open. It was a little finicky. It worked once, then stopped, and I had to close the DevTools and re-open again. I saw #johntrepreneur's answer about closing the browser, but unfortunately I have too many tabs open on too many workspaces, so that's too much of a pain, so I didn't try that, although I have to assume that would work.
Other solutions didn't work for me. Had to close and restart browser to be able to set breakpoints again.
This also happens when there is a JS error in your code.
Some sort of weird built in function in windows 10 i think because I did press a few buttons by accident. Some of my keys even stopped working in certain areas of visual studio. F.e the letter "c" stopped working in the find window.
Mine did this and no solution worked, i pressed alt, windows key and function key a few times and my problem went away.
Fixed as follows: For me, the issue stems from having set up Chrome to interact with operating system files. If you set this up, then the fact is evident from a green dot by the file name. At some point, I could not set a breakpoint in a recently edited file. I fixed this by disconnecting the interaction, as follows: When viewing "sources", above the code, there were some file names listed. Clicking the [x] to make the particular filename go away gave a caution message; I proceeded without saving. After that, I was able to set breakpoints for that file.
I also had this problem. However, once I closed the popup message in my browser, suddenly all my breakpoints that I set in that time appeared. Mental note: Don't set breakpoints while your app is showing a popup.
I couldn't find any direct fix for this problem.
It seems that chrome keeps settings of your site stored somewhere whatever you do to clean it. (I tried removing the folder from workspace, closing et reopening chrome etc... and nothing worked).
A workaround is to change your site's url to make chrome consider it a new site

Xcode 4 - simultaneous viewing of Project Navigator and Debug Navigator and other Navigators

In Xcode 4 (4.2), is there a way to keep the Project Navigator view open and Debug Navigator view open as well. Must a user have one or the other, but not both? And the other navigators?
Apple seems to have decided that if you want to see the debug view, you don't want to see the files in your project. WTH? Am I getting this wrong? Did Apple Xcode UI guys even talk to developers before designing the UI for Xcode 4?
Sigh...
You can indeed have more navigators open at once, if you are prepared to have multiple windows open. I know it's not exactly what you're asking for, but for multiple display setups it's very handy. Xcode provides "behaviors" to help automate this process if you only want certain things showing at certain times.
For example, a common pattern that developers follow is to setup a behavior for "Run starts" that opens up a new window setup for debugging. Start by creating a new tab in your main Xcode window by pressing command-T, and double-click on the tab's title to rename is "Debug", or whatever you like. Then drag that window out (or leave it as a tab if you like), and customise the view as required - for example, for a deb window you might have the Debug area showing at the bottom (or even covering the whole editor view), and remove the toolbar at the top by right clicking and selecting "Hide Toolbar".
Next, go to "Xcode > Behaviors > Edit Behaviors..." and choose "Run starts" in the left panel. Check the box for "Show tab" and enter the name of your newly created tab. You can also ask that tab to automatically show the Debug Navigator, and show the debugger with variables and/or console view. If you like, you can then choose "Run completes" and show the original "tab" (window), which I've setup to be called "Coding", and show the required navigator (in my case, Project Navigator).
On successfully running, Xcode will now open up your new window (or bring it to the front if it's already open) with all the settings you left it with. On stopping, your main editor will be brought back to the front.
There are loads of useful behaviors, so I would really recommend looking through them and taking the time to setup Xcode to suit your style as best as possible. All software dictates to the user how to go about doing things, and the developers can never please everybody when they decide to change the UI. The best anybody can hope to achieve is to customise the interface as best as they can to fit their style of working. If it's still an issue for you, you can either adapt to it, or, if possible, move to something else.
I'm not a fan of every new interface feature in Xcode, but I've "made it mine" with some customisations and I can still be very productive. That being said there are a lot of things that I do really like about it, and for that I can forgive it for some of the less friendly features - after all, you can't please every user.

In Xcode is there code that will open up the console for you?

Is there a way in Xcode to have your software open up the console for you? I would like to have it when my code compiles and runs in Debug to have the console open up automatically but in release for it to not open.
Thanks in advance.
A common way to achieve this is :
Open a new tab, and rename it 'Console' (or what name you want)
In this tab, show only the panes you want (in your case the console)
Go to Preferences>Behaviors
Tell Xcode to 'Show tab' and give it the name you set in 1. (you can set this at various moments, when build starts, or when app runs).
Now, each you will either compile or run your app, Xcode will switch to the tab you have set in Prefs.
You dont use code, you go to xcode pref's and do it there
This is where I came for the answer given and marked correct (although it's not clear it was what the asker quite wanted).
Arguably, a simpler version of the answer given is to set the Behaviors preferences to show the Debugger when a run starts. With the settings in the image below, this opens up the console (or the console + variable views or the variables view, depending on how it was last set - that's what 'Current Views' means).

How can I make the tabs work normally on Xcode 4?

Xcode finally added tabs but the problem is that they behave very strange. For example they will keep a tab open only if it was opened to a new tab.
If you open a file just by clicking in the project tree, Xcode will close your tab as soon as you are clicking on another file in the tree.
Is is possible to make them behave like real tabs and prevent Xcode from reusing them? How?
I use a method similar to franks:
In Preferences > Navigation (or Preferences > General in versions of Xcode prior to 5) you can set Optional Navigation to Uses Separate Tab
Now opt-clicking a file in the file navigator will open it in a new tab
Better yet, opt-clicking links in the code opens the destination file in a new tab
The big feature missing is swapping to an already open tab containing the file if there is one (or staying in the current one).
UPDATE for 2020:
Finally, almost 10 years later, Xcode 12.x now appears to mostly resolve the issue described here. There is a new Navigation Style option in the Navigation settings panel that controls this behavior.
The behavior has some new quirks/design-choices that seem to make sense, but I'm still getting used to the new experience. For example, a tab will get re-used unless the file in that tab has been edited recently; such a tab is indicated with an italics title.
PREVIOUS ANSWER
I don't think you can currently get the behavior you desire (or I desire). While the tabs work like Safari, they don't work like tabs in other popular IDEs (Visual Studio or Eclipse). And for me this kind of sucks.
In general, I expect IDE tabs to keep more than 1 file open. So if I click a file in the project tree, I expect that it will switch to the tab I have opened with that file - if I have already opened it. Instead, XCode 4 changes the current tab to the file I clicked - making 2 tabs with the same file. Having 2 tabs with the same file is fairly useless.
This forces the user to scan the tab bar first to see if the file is currently opened; if it's not opened then you can look to the project tree. But if you click in the project tree first (which is what I tend to do) then you get punished because you will have just killed a tab.
This isn't really an answer insofar as it contains a solution; I mostly just want to join in the griping. But upvoting will make you feel better and prove Apple wrong. :)
The problem with Xcode 4's implementation of tabs is that Apple has implemented them as workspace tabs. In other words, creating a new tab essentially creates a new workspace, each with its own sub-panes with their configurations, etc. It's essentially a whole environment in each tab. There are a number of problems with this choice.
This differs from most IDE/text editors' implementation of file tabs wherein a tab (generally) represents a single file, and each file has its own tab.
The problem with workspace tabs is there are only so many potential different workspaces we could benefit from, severely limiting the actual use of tabs in this way. Beyond this, the additional workspaces just become a liability, introducing more things the user of the application needs to concern him/herself with: for example, what the navigator view is, what editor mode is active (standard, assistant, version), whether the debug console is open, etc. etc. Suddenly switching to a new tab means you now have to worry about getting the environment back in the form you need it, because there's a good chance the other tab wasn't left in the state you expect to find it in. This actually discourages the use of tabs because it introduces more work in the workflow.
File tabs don't have this problem (not counting special cases like split view panes) because all that's changing is the file you're looking at, not your whole environment. Moreover, if implemented properly, file tabs work great as an immediate history, allowing one to quickly switch back to a file that was worked in recently, with little effort. The only way to do this in Xcode is to explicitly set up a new tab environment for each file you want to work with, but you have to be careful not to change the file in that tab or your file all of a sudden becomes lost: again, more work for the user.
Workspace tabs are also significantly heavier-weight than file tabs, because there is much more to remember and switching workspaces involves much more than switching files.
The truth is (and I think most will agree with me on this), to a developer, file tabs are much more useful than workspace tabs, and as it stands Xcode still lacks a proper implementation of this feature that many would consider basic required functionality in an IDE/editor.
Xcode->Preferences->General->Double Click Navigation and from the list, choose Uses Separate Tab.
Well, not a real answer but my personal workaround. The real problem for me is, that a file opened in a tab goes away so easily in xcode 4. Finding a file again can be time-consuming, so I like them to be in a tab and stay there.
I solved this (somehow) for me by exactly identifying the actions I do which cause the tab to switch to another file and replace them by their equivalent actions which open a new tab instead.
Instead of single-clicking a file in the navigator, I always double-click which I have set to open a new tab
Most time I do not use the navigator, as it has a different state of opened and closed folders in each tab. Not useful for me. So I switched to using Option ⌥ Command ⌘ O. When opening a file from this list I keep ShiftOption ⌥ pressed. In the small window appearing I choose 'new tab'.
When clicking on links in code I press ShiftOption ⌥ Command ⌘, too, and open in new tab.
I keep two fixed tabs around for editing target-related settings and to view build results. I completely disabled all automatic tab switching in the prefs, because I noticed this distracted me to much.
I would really love to get something like the xcode 3 favorites bar in xcode 4, this was so simple to use..
I imagine my answer won't bubble up for a while, but if you want this to work like visual studio or intellij (or at least closer)
Preferences->General->Double Click Navigation->Uses a separate tab
Double Clicking a file now will stop opening it in a new window and open it in a new tab.
Single is still dumb and takes over your tab. But if you get used to double clicking (which I was already) this will save you some headaches. I suppose.
I absolutely hate how tabs work in Xcode. However, the only workaround i found that works decent is using the OSX tabs shortcuts:
CTRL + CMD + ->
CTRL + CMD + <-
I found my way in Preferences-Behaviors!
I hated Xcode 4 first for the tab issues discussed here, mainly because the debug information kept opening new files in tabs and changing the navigator
in Behaviors you can define a Debug tab and make the Run and Build jump there in various ways. in the Debug tab I give more space to navigators left and bottom
for similar reasons I have a Find tab, too
the other tabs are for files I am writing in. I start them with the .h which is usually small enough so I need only one view, and then with single clicks in the navegator I open 2-3 versions of the .cpp file so I can set them to the locations where the recent hot spots in the file are. then I close the navigators in those tabs
this does not invalidate the care and tricks given in the other answers here, but makes them far less hard
happy coding!
I found out that when pressing option a.k.a. alt when opening files in the navigator, you will jump to the tab already open with the file and a new tab will open in case it was not yet open.
This technique also works when opening files via cmdshift-O and opening the suggestion with option-enter in stead of simply enter...
Now, if there would be some way to make this the default, i.e. the need to keep pressing option all the time would be removed, that would be a big step forward.
Also I use Behaviors to keep my tabs from being recycled after test or build failures.
(Like other people, I totally mislike Xcode's tab behavior. Apple should take a look at IntelliJ...)
xcode tab bar is so suck, I think Apple should enhance the feature of the tab navigation to avoid followed 3 points.
1. double click a file will let xcode open another tab if it has already been there.
2. for more tabs, the tab will become small and thus I don't know which file in which tab, I want the tab show full name
3. for even more tabs, new tabs will be hidden, instead of two lines of tabs. I want to it show two lines of tab bars.
If you have the tab bar enabled (View/Show Tab Bar) and you double click a file, it appears in it's own window, with a single tab (Be sure the Tab Bar is enabled in both the new and old (main) windows).
Now all you have to do is drag that new window from its tab and drop it into the tab bar of your main window.
It will stay docked as a separate tab, showing that file.
To change the file open in that new tab, go Project / Reveal in Project Navigator, which opens the project navigator at the left hand side.
Tabs in Xcode 4 work like tabs elsewhere on Mac OS X, for example in Safari and Terminal.
