I ran my code on simulator, Iphone 5 with xcode connected just fine.
When I deployed to an Iphone 4s device, the scrolling is lagging, clicking is lagging by a seconds.
These are my steps to deploy.
1. Create provision profile on apple developer site which include my iphone 4s device.
2. Import into XCode organizer - Provision.
3. Set Code Signing to Distribution.
4. Distribute it through email.
5. Double click on IPA to install the App on device.
Any reason that caused slowness?

When I first run my project from Xcode in iOS physical device, it work fine. But if I stop the project from Xcode and again start the application from the device, it shows the Splash screen and than quit. I don't understand what is going wrong on the second time.
In both of the cases I am on the same network.
Eventhough, Xcode 6 displays in iOS devices section my iOS 8.0.2 running iPad2 wirelessly and builds normally my app, when it tries to run end up the the following message:
Cannot retrieve value from the passcode locked device.
Please check your setup and try again. (0xE8000016).
Any ideas ?
Try restarting the device to make sure Xcode is referencing the correct device.
In my case, Xcode detected one of my iPads nearby as a wireless device (which happened to be passcode locked), but when I plugged in my other iPad it mistook it for the wireless one.
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 am using XCode 5, with an iPhone 5s as the dev device. Every other time I run the app I get a pop that says "Could not launch [app name] \n busy". My iPhone 5s then appears to crash and the only way it will respond is if I hold the home and lock button until it resets.
The application is a single view application, the only thing I have done is added the Parse.framework from here and used
[Parse setApplicationID:appID clientKey:clientKey];
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
In applicationDidFinishLaunchingWithOptions, along with some UI that isn't hooked up to anything.
I'm not sure if this has to do with Parse or possibly the App settings.
So to be clear, the behavior is:
Fresh reset > Build and Run application on iPhone 5s > application runs fine > Build and Run application on iPhone 5s > application appears to launch but screen remains black and iPhone is no longer responsive except the screen will turn off when the lock button is pressed (but not back on) > Build and Run application on iPhone 5s > XCode says "could not launch app - busy" > hard reset iPhone
When I run this on the 64-bit simulator it works fine.
Edit 1:
I have tested with multiple applications now that we know work on multiple other devices (iPhone 5, iPhone 4, iPhone 4s) and the simulators. I don't have another iPhone 5s so it is hard to compare exactly but everything crashes my 5s..
My device was completely stuck with black screen. "To fix you have to hard reboot, holding the power and home button until the phone reboots - doesn't lose any of the data you have on your phone (a concern the first time I did it)." as stated here:

For iPhone7 there is a different approach:
Press and hold down the power button located on the right side of
the iPhone 7.
While holding down the power button, press and hold
down the Volume Down button on the left side of the iPhone 7.

You were using your phone when you ran the app. Make sure you don't use your phone after you press build and run, otherwise it will be "busy"
Which Xcode version do you use? Same issue with Xcode 5.0.1 + iPhone 5S (iOS 7.0.4). It crashed my iPhone 5S even by the simple application created by Xcode's default project template.
It seems this issue has been fixed in Xcode 5.0.2. Xcode 5.0.2 works fine for me by now.
I've got the same problem for several times. It seems that this problem always happens when iCloud or other background App is running & the App I was debug is already in running mode.
My suggestion is: Avoid any background App running when debug and Make sure the App debugging is fully killed before restart a debug.
It is obvious a bug in iOS 7 + Xcode 5.
I had the same issue and upgrading to Xcode 5.0.2 resolved it.
I have an app that i am release as iPhone and iPad even if it developed as Universal. The reason is that i have release an English version that is Universal and just want to update the iPhone and iPad Swedish versions as it have been with separate apps for the different devices.
When i run on the iPhone device i have no problems but when testing with iPad i get the message below, which i do not know how to remove:
"Could not launch “FamilyQuiz_3"
No such file or directory (/Users/peterk/Library/Developer/Xcode/DerivedData/MyApp_3-fosmfwberzyfryenqrjlfpacftjv/Build/Products/Debug-iphoneos/MyApp_3.app/MyApp_3)
I can start the app from the iPad device but it do not start automatically when submit from XCODE.
1)make sure your iOS Deployment Target version is the same or lower than the one on your device in build settings.
2)delete it from the device
3)close xcode
4)Goto /Users/peterk/Library/Developer/Xcode/DerivedData/ on your computer and delete the
MyApp_3-fosmfwberzyfryenqrjlfpacftjv folder
if that still doesnt work go and try deleting the app restarting your phone, and then restarting your computer even, and doing it again.
