I downloaded Xcode 6 but got an icon with a Stop sign. After copying it to Applications, it remains the same and won't react to click. Any idea what I am missing? I am running OSX 10.9.3.

This is the message I got when I tried to run my app in Xcoded 7.3. I worked with this app with version 8.0 a bit.
Swift version doesn't seem to have any problem, for it is still 2.3.
The project format setting is set to 6.3 so I think it's supposed to be run in 7.3 too but it doesn't.
Do I need to do some more things to get this run in 7.3?
Storyboards opened in Xcode 8 can't be opened up in Xcode 7 or 6.
If you go to your Main.storyboard inspector, you can change the format back to Xcode 7, like this:
When you do this, you'll get this warning in Xcode 8:
And yes, you can go from Xcode 8 back to Xcode 7 format, but you can't go back to Xcode 6 format from Xcode 8. If you want to get back to Xcode 6, you might have to open Xcode 7 first and repeat the steps I showed above to change the "Builds For" format pop-down menu.
I took a running app that was built under XCode7 and since I'm going to make some updates to it, did a build with XCode 8. After the first build (it was successful), I got a series of "suggestions" that XCode 8 wanted to automatically make for the app. Since I've never had problems doing that, I clicked OK and did another build under XCode 8. Now my app won't link properly! (It's happening on two separate apps, both using Crashlytics and Ensembles)
How can I backout the changes that were automatically made to the app by XCode 8?
If you are using source control with your project, you can go back to the last committed state of your .xcodeproj file. Maybe this is not too far away from the state right before you switched to Xcode 8.
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 !!
Using Xcode 5.1 to debug an iOS 7.1 iPad application.
When I build and run my project in the iOS Simulator, the simulator opens and my app icon pops up for a second. Then it looks like the app stops installing and the simulator goes to the home screen. Xcode still thinks it's debugging and it doesn't show any errors in Xcode or the simulator. I can go to my app in the simulator and click it again, but it just crashes. I get the same behavior in iPad, iPad Retina, and iPad Retina (64 bit). Any subsequent tries to run the app in the simulator doesn't even attempt to pop the app icon up until I quit the iOS Simulator and try again. All the usual fixes haven't worked for me yet.
Fixes I've Tried:
1. iOS Simulator > Reset Content and Settings...
2. Window(in Xcode) > Organizer > Delete Derived Data & Delete Snapshots
3. Delete Contents in ~/Library/Application Support/iPhone Simulator
4. Uninstall Xcode and reinstall
5. Clean project and rebuild
6. Restart machine
I'm out of ideas. Is there something I've missed?
Thanks all!
Create another app with the exact same template and look at the app delegates and make sure they are the same.
Example: AppDelegate.h and AppDelegate.m
You might've accidentally deleted an area that helps load the App.
Alright I found the problem. I was playing with how we load our frameworks because we were having other issues before and I left a bad value in our Linking settings.
Here's how I fixed it:
Project > Build Settings > Linking > Mach-O Type set to "Executable"
It was set to "Bundles" before which causes Xcode to package the app in a way that caused ours to break.
Helpful Post: In Xcode project target build settings, What is Mach-O Type?
