If I open Instruments and select a standard application (e.g. Mail or MS Word) it has no issue.
If I am in Xcode and I go to Product > Profile (or press Cmd + I), it launches Instruments, allows me to select a template, and loads the standard screen. Then the downward arrow starts tracing to the right as it should, and the iOS simulator launches the program. However, nothing is plotted in Instruments. It shows no changes to anything no matter what the app is doing. I can't click anything in Instruments: no menu's, can't stop recording, can't open tabs, etc.
I randomly discovered that if I hit Cmd + Tab, Instruments will start behaving normally. This seems really strange to me. Either it's a bug or it's a hole in my knowledge about how to operate Instruments.
Strange bug is fixed in XCode 4.2!
The problem was the hidden password dialog, so sometime it works and sometimes not.
One of possible solutions was:
Run Instruments
Cmd Tab to Xcode covering the instruments. Cycle and hide messages until password dialog is found.
Close Xcode.

I have a MacBook Pro running Catalina with an additional display. I typically have my development-related apps on one display (iTerm2, VSCode, etc.) and everything else on the other display (Chrome, Slack, etc.)
Sometimes (not all the time), when I switch desktops (Ctrl+left or Ctrl+right), access an app using Spotlight (Cmd+space and type), or use Cmd+Tab to switch applications, the focus would suddenly jump to iTerm2 or VSCode. This happens even if iTerm2 or VSCode isn't currently showing; for example, if I try to switch to Chrome on display 1 and iTerm2 is on a different hidden desktop on display 2, Chrome would appear on display 1 and then display 2 would show the desktop containing iTerm2 sliding into view (along with focusing iTerm2).
This severely impacts workflow, since this behavior is unpredictable and involves a lot of typing in the wrong application and reaching for the mouse. What is causing this behavior?
I found that it only happens when I have windows of the same app on both screens.
Say I switch desktop on a screen 1 and Chrome should become active there, then if I also have a Chrome window on my screen 2, it's actually the one on screen 2 that becomes active. Very frustrating..
This bug still exists in macOS Big Sur 11.4. Another symptom is that, after the erroneous focusing happens, manually switching to a space with no windows in it will leave that focused app focused, after briefly focusing Finder, rather than just focusing Finder. It's this last erroneous focusing that causes the space-switching.
Workaround: when it happens, invoke "Show All" from the menu bar (I have a keyboard shortcut for this). Note that switching to an empty space now does a single focusing of Finder, and no further space-switching happens.
Since this morning I'm facing a really annoying bug in XCode 5 on Mavericks :
I'm heavily used to swipe from left to right with two fingers on the MacBook trackpad to go to the XCode editor previous / next files.
BUT, now, doing this totally freeze the editor after having just moved for something like 5 px.
After that I have to close XCode and reopen it to make the editor work again.
Pressing the previous / next button works wel since it doesn't trigger this buggy animation.
Did anyone had this problem before or has any clue to solve it ?
In fact this problem is affecting other swipe gesture like the previous / next swipe in Safari.
I found a way to fix this on Apple Support Forum, by resetting the NVRAM.
Shut down your Mac.
Locate the following keys on the keyboard: cmd ⌘alt ⌥PR. You will need to hold these keys down simultaneously in next step.
Turn on the computer and immediately press and hold the cmd ⌘alt ⌥PR keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
When your Mac finishes starting up, you might want to open System Preferences and adjust settings that have been reset, such as sound volume, display resolution, startup disk selection, or time zone.

For me, in Xcode 8.3.3 and Xcode 9, it started working after
Go to the system preferences
Go to Trackpad
Select and deselect "Tap to click"
I'm running Version 5.0.1 (5A2053), and every time I click the play button to run my app on an iPad, the right panel opens.
It does not provide any value whatsoever to me, and after closing it ~200 times, I'm interested if there's some Xcode 5.0.1 setting to prevent right panel from showing up when running apps on device.
Sorry if this question is not very programming oriented, but it definitely adds a bit of frustration over time.
With the default preferences, it should not happen. If it is, then go to Xcode>Preferences>Behaviors, and on the left side, click into everything with a checkmark besides it.
There is a section on the right side that says Show/Hide Utilities. Uncheck it in every one you can. Don't do this in ones one the left without checks, because they already have that off by default. Hope this helps.
Edit: Unchecking this flag in the "Starts" section fixed the issue:
Basically I am supposed to press Command + the [`~] button that is above the Tab.
This question has been answered twice here:
Tabbing between Xcode projects?
and
Navigate Between Projects in XCode 4.0
But it just wont work for me, has anything changed in the xcode versions? or the way the mac behaves?
When I press this combination all I hear is the "invalid" sound.
I am using the newest Mac OS mountain lion.
Sorry if this belong to the super user stack overflow I just figured more Xcode users would be found here.
I can do the swipe on the mouse pad to bring the screen where I see all the active windows for the current application... but this is much slower than just tabbing between the 2 projects I'm usually working with.
Thanks
Do I infer from your comment about using the three finger swipe (for Mission Control) that the second window is not on the same desktop as the other windows? The command+` sequence only jumps between windows on the same desktop, not between different desktops (which is not to be confused with two physical monitors, which you can jump between, if you have multiple monitors hooked up to your computer).
The inability of command+` to not jump between desktops is a little curious, because command+tab, which jumps between apps, does go across desktops. If you want to jump between desktops, you can press control+1 or control+2 to jump to desktop 1 or 2, respectively. It should be noted, though, that while that might be a good alternative when trying to jump between your two desktops, though it admittedly selects the last active window in that other desktop, not necessarily a window from your current app in that other desktop. Also control+left and control+right let you jump between desktops, too.
This is a Mac OS "feature", not an Xcode issue, I believe. The command+` ability to jump between windows (but not windows across Mission Control desktops) is the same behavior across the Mac OS.
Update:
If this keyboard shortcut is not working at all, in any app, even within a single Mission Control desktop, then you don't need to worry about Xcode settings, but rather focus your attention on the keyboard settings:
You might want to look at your "Move focus to the next window" keyboard shortcut. There have been reported problems of people with international keyboards not getting this to work properly, but by clicking on (and thereby selecting) the command+` graphic, you can try using different keyboard shortcut, and see if that does it for you.
I have mountain lion as far as i know.
How about this?
control + down
You'll get the current application windows.
Below them there should be a horizontal list of recent projects for Xcode (both opened and closed). With arrows left or right choose the project (it should be highlighted with blue) and press enter.
Well, the title pretty much sums it up, really. I've only just started toying around with XCode and stumbled upon this while coding the obligatory "Hello, World" app. When I click "Build And Run" (or just Run), my app runs, but XCode doesn't bring up the console window, so I can't, for example, see its output.
If I double-click the executable on the Detail View list, the terminal window appears as expected.
I suspect I'm doing something stupid, but don't know yet what it is. I'm running XCode 3.2.2 on Snow Leopard.
Thanks.
⌘-, select debugging, and change the "on start" value to "Show console & Debugger."
You can choose the other options, depending on your style. See the debugging guide for more details.
-S!
