I found Simulator show up very slowly. It takes me nearly 10 seconds to show the Simulator after building successfully by pressing Command + R, even with a new Project.
I'm using Mac Lion + XCode 4.5.2
This issue happens when there is no memory or there is a hang in the Xcode or the simulator, try to completely close the Xcode and the simulator i hope this will solve the issue
The first time the simulator starts up tends to be much slower than subsequent startups. I'm using an SSD in my MacBook Pro and that helps as subsequent startups of the simulator are quite fast. It may also help you to change your derived data directory, typically ~/Library/Developer/Xcode/DerivedData, to a RAM disk under File > Project Settings. I'm using Mountain Lion, Xcode 4.5.2 with the iOS 6 SDK and have 16 GB of RAM.

Just created a Today Widget and all seems to be good (on ios 8.3) devices. It installs and runs fine from XCODE 6.3.1. But on iOS 8.2 or 8.1 devices, the Today Widget does not install / run even though XCODE says it is running.
If a breakpoint is put on ViewDidLoad it never gets hit. Will try and do some digging in the logs, but so far nothing...
Need to make sure that the deployment platform for the Today Widget is set to 8.0. It was created and set to 8.3 and XCODE did not have any error messages when trying to run on 8.1, 8.2, etc.
I have a piece of software I wrote using xcode 5. Since I upgraded to xcode 6, the app looks strange when I run it on a physical device using the emulator. Not entirely sure what is going on or how I could fix it. It's not respecting the full size of the screen.
I am testing on an iPhone 5s (NOT simulator -- the app looks fine in the iPhone 5s simulator). I am connecting my phone to my comp and running it via xCode.
I am having the same issue with another project I built using xcode 5 and trying to run again in xcode 6...
thoughts anyone?!
Here is a screenshot of what is going on:
I have an iPhone with iOS 8 installed on it, but when I connect it to Xcode 5.1, it doesn't recognize it.
As with the other answers, it seemed fairly random whether or not my iOS 8 device was being picked up by Xcode 5.1. It appears that it works if you have the iOS 8 device plugged in before you start Xcode 5.1. When you do that, you will get a screen indicating the symbols are being processed:
After this completes, the device is selectable. I am pretty sure this needs to be performed with each new beta. That might explain why it appears to suddenly stop working.
If this isn't working for you, make sure you have the latest Xcode 6 Beta to match the iOS 8 Beta version, and connect the device while Xcode 6 is running. The same "Processing Symbol" files process will occur and then Xcode 5.1 seems to work.
the only decent way to make it work is to create a symbolic link to a folder that contains binary for iOS8. You can make fool Xcode 5.1 saying "yes, iOS 8 is ok." via a symlink:
In my case I have Xcode 5.1 on Mavericks HD, and Xcode 6.0 beta 4 on Yosemite HD.
I did:
sudo ln -s /Applications/Xcode6-Beta4.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/8.0\ (12A4331d) /Volumes/MAVERICKS/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/8.0\ (12A4331d)
and Xcode 5.1 did work with my iOS8 iphone.
(note the space before /Volumes/MAVER... )
PS: for every beta, I have to patch again... :(
You need to download the Xcode 6 Beta. It's available in the iOS Developer Center, where you downloaded the iOS 8 Beta.
I have connected my iPhone with iOS 8 installed to Xcode 5.1.First time it doesn't recognize.but when i unplugged device and connect again , Device Recognized.
I dont know the reason Anyway i am sure that you can also connect your IOS8 installed device to Xcode5.1 ....
I've been using Xcode 5 to build on an iOS 8 device just fine. Now all of a sudden, it won't let me anymore.
first use xcode6 build on your iPhone5s.
second open xcode 5 ,unpluge device and connect again.
then device recognized.
Open xcode 6 and wait until device is recognised. When done, close xcode 6 and open xcode 5.1 and your device is going to be automatically recognised.
That way you can run your application on a device with iOS 8 with the old xcode.
Apple has now announced Xcode 6 (and iOS 8). I currently have Mavericks on my Mac (and am not planning to upgrade to Yosemite yet), and am wondering if I can download the Xcode 6 dev preview, while still maintaining my current version of Xcode 5. This is so that I can use the new Xcode 6 features, while still being able to work on, and upload, my current applications. Is that possible?
Also, if I update my phone to iOS 8 Beta, will I be able to run apps from Xcode 5, or only Xcode 6?
Answers would be hugely appreciated! Thanks :)
Even I use Mavericks, I installed Xcode 6. In order to be sure about my maintenance projects, I've also downloaded Xcode5.1.1 from Apple developer portal, copied it into my Desktop, renamed it as XCode 5.1.1 and then moved it to my applications folder.
I have both versions at the moment without any issues and can also select the version of Xcode while opening an existing Xcode project by using open with menu feature.
I hope this helps...
Xcode 6 Beta Release Notes
Xcode 6 Beta requires a Mac running OS X version 10.9.3 (or later) or 10.10.
I think its possible that you can do all things you was able to do with Xcode 5 but I will tell you when my xcode 6 download is finished.
You may install XCode 6 Beta on OS X 10.9.3, and I think that you'll need XCode 6 in order to run iOS8 apps.
One thing that you didn't ask, but that you should keep in mind (as you mentioned your phone):
Devices updated to iOS 8 beta can not be restored to earlier versions
of iOS.
i've installed Xcode6 in Mavericks and iOS simulator crash with message : Unable to boot the iOS Simulator. :-(
You can download the preview of Xcode 6 and use your existing installed Xcode 5 side by side without affecting anything you're doing. Just make sure if you click on a project file that you open it in the correct version of Xcode.
Download xcode dmg file from Apple's developer site. Install it in a different location other than the Applications folder. There you go !!
My kids want to learn to write apps on their MacBook which currently runs OS version 10.5.8.
I have downloaded Xcode 3.1.4 but it doesn't seem to have the iPhone Simulator.
Does anyone know where I can find this?
(And are their better tags I should use for this question?)
Thanks.
(UPDATE: I down loaded the " xcode 3.2.6 & ios sdk 4.3" dmg file from Apple in the hopes of accessing just the "iPhone simulator" but repeated attempts to open the .dmg file on my OS10.5.8 Macbook result in a complete, "blackscreen" crash.)
I am really very sorry because this is not straight to your question. But if I were you, I'd like to encourage them to start with Android. To me, an open-platform is more preferred. Beside that, Java is a strong/ dynamic language when comparing to C/C++.

Eclipse IDE
Android SDK
ADT plugin for Eclipse

Hope they will like :-)
Are you sure the simulator was not included? One thing to remember is it won't be shown with xcode in your applications folder.
To use the simulator you have to launch it from xcode by pressing the play button in the top left corner of the interface. If you have already used xcode with an iPhone/iPod/iPad make sure you select simulator from the drop down next the play and stop buttons(press and hold to change what is selected).
If you want to make sure you can access the simulator without xcode, launch the simulator as described above and then right click(or ctrl click) the icon for the simulator and select keep in dock from the options menu.
Hopefully the above helps you with your problem. If xcode truly did not come with the simulator your best option is to uninstall xcode(after backing up any projects) and trying a fresh install. Also try checking Apples dev center (https://developer.apple.com/devcenter/ios/index.action) for information about xcode and the simulator.
