Just upgrade my Xcode from 7.2.1 to 7.3. Have no idea why. Do I have choices other than delete Xcode and reinstall again? (which I highly don't like).
BTW, the documentation tab is fine. Just a blank simulators.
Update: If I click "check and isntall now", it reports:
Could not download and install OS X 10.11.4 Documentation. The certificate for this server is invalid. You might be connecting to a server that is pretending to be “devimages.apple.com.edgekey.net” which could put your confidential information at risk.
I checked cert on https://devimages.apple.com.edgekey.net, seems fine..
In Xcode 7.3 I found the following way to add older simulator versions.
1.) Choose "Window" from the menu bar
2.) Choose "Devices" from the drop down menu list
Result: Devices window opens
3.) Click the "+" icon in the lower left-hand corner of the window.
4.) Choose the Add Simulator option
Result: You can add a simulator (and download older ones).

Can't see any iOS 9.0 simulators. In previous Xcode 7 beta 3 all was OK.
Can't install iOS 8.3 simulator.
Also I can't add any simulator from 'Organizer'. By pressing "Create" nothing happened.
Each time when I'm trying to download iOS simulator I see next thing:
One possible issue is that there may be old leftover simulators installed, which are not compatible with the new XCode, and their presence causes the whole Simulator to fail. To get rid of them, delete the simulators in /Library/Developer/CoreSimulator/Profiles/Runtimes (for me there was an iOS 7 simulator there which was the issue). Relaunch XCode after this.
Then try to run the simulator from XCode->Open Developer Tool->Simulator. Assuming this succeeds, verify that you have the simulators under the iOS Simulator menu Hardware->Device->Manage Devices… – if not, you should be able to click the + in the bottom bar to add yourself some iOS 9 simulators. Relaunch XCode again and they should show up in the menu.
In my case was with Xcode 8.2, what it worked to me was changing Deployment Version:
After setting another different than 10.0 then appeared back all simulators again.
Have you tried going to Xcode > preferences > downloads and trying to re-download the simulators you want?
For me it was only showing one simulator,
and when I go to Xcode > Preferences I can see the simulator is already downloaded but it is not showing up in the list,
if you're facing something similar. This is how you should add required simulator,
From the Xcode menu, open Windows > Devices, shown in the image below
you should see this screen,
notice there is only one simulator (ref: first image)
Now to add required simulator, you should click on the + (in the left corner)
You should see this,
You can choose the simulator from the list, In my case it is iPhone 6s Plus.
In Xcode you can see additional simulator iPhone 6s Plus,
I was also not able to see simulators.Reason is,I have not restarted system after upgrading Xcode.I restarted & simulator started displaying as routine.
There is a bug in the latest El Capitan beta which causes a process to crash when dlopen() fails to mmap() a dynamic library. Such mmap() failures can occur due to code signature verification failures.
These mmap() failures will occur if older iOS Simulator runtimes are present on disk (ie: installed from Xcode 6.x), and that is the reason why Xcode 7 beta release notes have indicated that earlier runtimes are not working in Xcode 7. The iOS 8.x Simulator runtimes were updated in newer downloads, but if the older versions are present on disk, they will cause the mmap() failure, which in the latest El Capitan beta, unfortunately results in the CoreSimulatorService repeatedly crashing which in turn results in no simulators being available.
If simulators are suddenly disappeared:
Just consider decreasing Deployment target to a minor version below current version in Project > Build Settings > Deployment Info > Deployment Target
P.S. Usually you see a place holder text showing the selected version (in gray) in the box denoted above. If for example the gray text says 9.3, then decrease it to 9.2.
Look at seancook's response in the middle of this page... it seems to have fixed this issue for several people.

Edit:
This can also be fixed by booting into recovery mode (CMD - R) and reinstalling El Capitan.
Go to Windows. Select Devices. Select '+' from left bottom and add all simulators one by one.
I had changed the name of my Project from Finder. I clicked on the old project name (between the Play Button and and the selector for the desired Simulator or Device), selected edit schemes, selected the Targets Tab, and realised that the old scheme was missing so I just added my new Project name by clicking on the plus button and the simulator list reappeared.
Today in the morning I tried to compile my project to run in my device and I found the destination toolbar disappeared and I cannot choose my IOS device or IOS Simulator device as target. (I can do it in the Product/Destination Menu)
After some research I found the >> at the right on the screen and when I pushed a Scheme option appeared but it is disabled and I can't enable again.
This is what I tried with no success:
Open an old project to see if the problem was in my project
Create a new project (with Swift and Objective C but I don't think this make any difference)
Restart my computer
Hide and show the toolbar (View menu/Hide Toolbar and the View menu/Show Toolbar)
I tried all the previous options with the device connected and disconnected
I have installed the IOS Simulator 8.4 (when I run my project it runs in the last selected simulator) and XCode 6.4.
Looks like Xcode hides that menu when the window is a certain size. I have to make my window quite large before it comes back.
Not a fix as such but you can work around it using the menus: Product > Scheme and Product > Destination
You're probably running into the same issue I am. Like #BrandonWilliams said in his answer, it appears again if the Xcode window is wide enough. The underlying cause, for me at least, seems to be that in this build of Xcode (6.4) running on El Capitan beta 2 (with Xcode 7 beta installed), I am seeing duplicate simulators for iOS 8.4. And since there are two of the same version, the Schemes dropdown shows some sort of long GUID next to each one, causing the Scheme dropdown to be quite large:
I came to SO looking for an answer but realized that I had seen this issue before.
So the problem is basically that auto layout sucks (I mean it is not working properly in Xcode 6) and on El Capitan, the destination toolbar is for some reason hiding instead of collapsing properly. So when your Xcode window is narrow, the destination toolbar disappears.
But, if you expand the window far enough, it shows back up again.
In case you can't tell, in the first screenshot, the window is about 1241 pixels wide and in the second screenshot the window is 1541 pixels wide.
Go to Product then Destination and choose at which simulator or device you want to test your build.
I'm running with same problem. You can select device or change scheme using below steps:
Select Product from menu
Select Scheme or Destination
Select required Scheme option or Destination option
Alternative Solution:
The only solution is to use Xcode 7 or above. I've installed Xcode 7.1 and found Scheme/Simulator list available. Refer screenshot.
It seems that Xcode 6 or below doesn't support OS X El Capitan.
I am still seeing this problem in Xcode 7.2 on iMac with resolution 1920x1080. Resizing the XCode windows dens't help. I can have the menu bar back if I push the green button and go to full screen mode. But that's pretty annoying. This is how I finally figure out a solution that works for me. I notice that only if I open the project file that I have been working daily that the menu bar is missing. If I create a new project, the menu bar is there. And here is my solution:
Remove your project file on disc (or move it to a different folder)
Open the Welcome to Xcode window by shift+command+1
Make sure your project is no longer under this list. If it is still there, click on it and Xcode will tell you the project is not found and it will be removed.
Add the project file back and open it and I have my menu bar back (if you have moved it, simply opening it from a different file location may work I guess)
I guess the problem is that some cache value in Xcode about the project file is messed up somehow. Hope this helps.
I make my XCode screen little big and now find both options.
On XCode 9.0 beta, this worked for me: select View -> Show Toolbar from menu
right click on title bar -> select show toolbar
Fixed it by deleting the following file ~/Library/Preferences/com.apple.dt.Xcode.plist and restarting Xcode.
The downside is that Xcode preferences dropped to defaults obviously.
I have strange behavior of XCode, if someone could explain it to me it would be very useful.
So the thing is that I've updated XCode 6.2 to 6.3 at 10th April.
Mac App Store app says that my Xcode is 6.3 now, but Xcode itself says that it is still 6.2 (in the XCode > About Xcode menu).
Why?
Odds on, your Dock has an Xcode from another location on your disk. Right click on the dock icon when it's open, select Options, then Show in Finder. What's the path to the folder (right click on the title of the Finder window)? If it's not /Applications, then drag it off the Dock, and grab the App Store version from /Applications.
In Xcode 5, i have a problem with installing simulators. They don`t show up in the downloads section of preferences for Xcode. And the 6.1 simulator cannot be run when it says its installed. Only shows up with a question mark besides it. When i click check and install, it says nothing new found. How to fix this?
When i try to run an app, no simulators show as installed:
It shows you installed all the simulators.
Just Quit the Xcode and open again. It wil show you a window same as below.
Also please cross check that, the downlaoded SDK's are available under Application->Xcode.app->right-click->Show Package Contents
->Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
Also cross check the Base SDK and Target devices.
So I'm horribly confused by this error, other threads on Stack Overflow mention I should set the SDK, but I see no option to do this. I'm trying to build:http://wafflesoftware.net/shortcut/
And I get no options, and I can only choose My Mac 64-bit, and I want it in 32-bit. Really beginning to hate Xcode 4.
Here is the screenshot when I try to edit my scheme: http://groovyape.com/scheme.png
Thoughts?
Firstly, I have observed that when Xcode 4 decides my Mac is 64 bit and all my other schemes have vanished, a restart of Xcode fixes that.
If you still have the issue after a restart, go to Manage Schemes... (under the Product Menu) and click on Autocreate Schemes now button. Try to delete the other schemes and see if you can run the project now.
However, if the issue is that you need to set the SDK, that's different:
Click on the top-level project icon in the left hand panel
In the right hand panel that appears, select Build Settings (near the top).
Select "All" option (instead of Combined)
Ensure Base SDK is set appropriately, like "OS X 10.7".
FWIW I'm seriously considering reverting to Xcode 3.2.5 at the moment, 4 seems horrendously buggy.
In xCode 4.4.1, use Validate Settings to solve the problem!
I can select either 32bit or 64bit now.
Ran into the same error message ("The selected run destination is not valid for this action") when attempting to use XCode 4 to build/run a tiny Objective-C "Hello, World" project I created in XCode 3.x. Fixed it by choosing to "Manage Schemes..." from the drop-down menu to the right of the Stop button, deleting the one scheme on the list (click checkbox beside the scheme, then click the "-" button at the bottom left), and then clicking "Autocreate Schemes Now".
I also needed to change the "Base SDK" from 10.5 to 10.6, by clicking on 'folder' icon (beneath the Run button), clicking the root/top of the tree view below it, clicking on the blue icon below "PROJECT" in the pane just to the right, and then finally, choosing "Latest Mac OS X (Mac OS X 10.6)" to the right of that.
I had this issue today. I found switching Base SDK from Latest iOS (4.3) to iOS 4.3 fixed everything.
This will happen if XCode believes your mac is a 64-bit machine, when really it's a 32-bit. If this is the case for you, simply click on your project icon from the far-left pane - it's the menu item that displays your project name next to a little blue icon. This should bring up a center pane that says "PROJECT" at the top. Highlight your project name, and the third pane should now show your build settings. The first item is "Architectures" which will allow you to specify if you are building a 32-bit or 64-bit application.
Kind of amazing that none of the answers here solved the issue for me, but I figured it out. Forget restarting Xcode, or using Autocreate Schemes, still only 64-bit will show up as a valid destination in the scheme.
The correct solution is to change the Architecture for your project. Go to Build Settings (in the root node of your project), and change Architecture to 32-bit Intel, it's right above the Base SDK setting. Destination will instantly switch to "My Mac 32-bit". HTH somebody.
It sounds as if you're trying to run (Cmd-R or run button) the framework (which you can't do - it's not an executable, just a library) rather than simply build it (Cmd-B).
I had this issue and maybe it was a coincidence but when I restarted XC4 but this time didn't choose to load my project from the popup window that appears on launch - instead choosing it explicitly from the File menu - the issue didn't occur and the build started ok.
On the 3 or 4 occasions I had this error, I had chosen to load the project from the popup window that appears when XC4 first loads.
As I say, I might have just got lucky, but I certainly didn't make any other changes to the projects to 'fix' the issue.
I found a good practice for moving from Xcode 3.2.X to Xcode 4 is, to remove any references to older SDKs (in the case of Mac OS to remove any Base SDK Ref, etc., for Mac OS <= 10.5, in the case of iOS I think you need to remove everything <= 4.3) PRIOR to upgrading to Xcode 4.
I never experienced any problems for new Projects, created in Xcode 4, only for such that where created with Xcode 3.X or 2.X
Xcode 4.5. I was trying to compile for 10.6. It seemed to be stuck on 64 bit just because it couldn't find the sdk. I didn't get any message about it not finding the sdk.
I first tried to put in the correct path to /Developer-3.2.6/SDKs/MacOSX10.6.sdk but xcode didn't want to find it there. Then I copied that folder into 4.5 next to the other OSX Platform sdk (new location I think just look in the bundle).
And magically my 32 bit came back.
So my conclusion is that the 32/64 bit option is really dependent on whether xcode can verify the sdk that you're trying to use. Being stuck at 64 while trying to compile for 32 gives the error without notifying you that its first issue is that the sdk can't be found.
I fixed this by deleting my xcuserdata in my Project file. Not sure how it got corrupt. But it worked for everyone else in the office, deleting the xcuserdata did the trick. I made sure Xcode was closed while doing so. Just for fun, make sure you delete your DerivedData folder for the app, and do a build clean for superstitious folks.
If this happened after you renamed your app, go to Schemes -> Edit Scheme -> Run <YourApp> -> Info
Select the right executable file (YourApp.app)
Another way is to select None as executable and then reselect the YourApp.app from your Debug-iPhoneOS folder.
