I was trying to test my app on my iPhone 4G iOS 5.0(latest software) on Xcode(latest software), but when I open 'Organizer' and this message(below) shows under device.
The version of iOS on “User Name” does not match any of the versions of iOS supported for development with this installation of the iOS SDK. Please restore the device to a version of the OS listed below, or update to the latest version of the iOS SDK; which is available here.
OS Installed on Moo 5.0 (9A334)
Xcode Supported iOS Versions Latest 4.3 4.2 4.1 4.0.2 4.0.1 4.0 3.2.2 3.2.1 3.2 3.1.3 3.1.2 3.1.1 3.1 3.0.1 3.0
How do I do to make my app run on my iPhone again? Just wondering why there isn't an option of iOS 5.0 in Xcode, where it only has iOS 4.3?
You can only build for iOS 5 with XCode 4.2.
Xcode 4.2 is on the Mac App Store. Note that there may be an installation issue that will keep you at 4.1; I'd recommend uninstalling Xcode first and then running the Install Xcode.app that MAS gives you.
You'll need Xcode 4.2 (4.1 was released for OSX Lion) and the iOS5 SDK. Both are available from http://developer.apple.com
Also notice that when you download update for Xcode 4.1 from App store it won't install itself alone, it will only download XCode installer which you need to run to update 4.1 to 4.2 and it will give you iOS5 then in frameworks.
Apple updates Xcode 4.2! Adds iOS 5 Support!
What’s New in Version 4.2
- Includes SDKs for Mac OS X 10.7 Lion and iOS 5
– Storyboards let you design multiple iOS screens, and define the segues among them
– Automatic Reference Counting (ARC) saves you from manually managing retain/release
– iCloud entitlements are automatically enabled for Mac and iOS apps
– OpenGL ES Debugger graphically analyzes your OpenGL scene directly within the IDE
– Apple LLVM compiler supports C++11 features and the LLVM libc++ standard library
– Older iOS Simulators and device debugging symbols are downloaded on-demand
Enhancements and fixes in previous Xcode updates:
– Interface Builder support for Auto Layout and new Aqua controls such as NSPopover
– Full screen support in workspace, project, and organizer windows
– Project editor can validate and resolve out of date build settings
– Behaviors can be customized and assigned to unique key bindings
– Source control enhancements to pushing, pulling, and management of remote servers
– Assistant editor support for display of generated assembly and preprocessed output
– Additional bug fixes and stability improvements
Download xcode 4.2 from the the App Store and install it to somewhere else like /Developer-4.2. Then to test with a device on iOS 5.0 IN xcode 4.1 do the following in a Terminal:
[ 16:39 root@MacBookPro / ]# cp -rv /Developer-4.2/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/ /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
[ 16:40 root@MacBookPro / ]# cp -rv /Developer-4.2/Platforms/iPhoneOS.platform/DeviceSupport/5.0/ /Developer/Platforms/iPhoneOS.platform/DeviceSupport/
This will copy all the necessary files over to your xcode 4.1 install, and the device will show up in the organizer and you can test your App on an iOS 5 device while still using xcode 4.1!
