ios 8.1.2 not running on Xcode 6.0 - iphone

Is iOS 8.1.2 supported by Xcode 6.0 and OS X 10.9.4?
When trying to run, Xcode shows a message that there are "Ineligible devices (OS Version)"

You need to update your OS to 10.10.1 and install Xcode 6.1.

Update your Xcode. You did not specify the Xcode version so I can only assume.
If you have Xcode 9:
Update your Xcode version. If you macOS is incompatible please refer to this link
If you have Xcode 10:
Please make sure you have the latest version of Xcode from developer.apple.com

Xcode restKit error after updating into Xcode 4.5

I have an application running successfully on Xcode 4.2 iOS 5.1, when i updated to Xcode 4.5 to make the application compatible with iOS 6, when i run the application it gives an error
Apple Mach-O linker error: no such file or directory: '/Users/User/Library/Developer/Xcode/DerivedData/Build/Products/Debug-iphonesimulator/RestKit/RestKit'
Note that i have moved the whole project from a Mac that was running xcode 4.2 into another Mac running Xcode 4.5
Thanks in advance
Just goto BuildSettings of the Project and remove armv7s from Valid architecture

Can't debug on iOS 4.x devices

Whenever I try to debug on devices with iOS 4.x (iPhone 4 and 3GS) I get the following error:
error: failed to launch '/XXX/Library/Developer/Xcode/DerivedData/XXX-fytptbaixvmoweacfsniqxtvjkst/Build/Products/Debug-iphoneos/XXX.app/XXX'
-- Bad CPU type in executable
On devices with iOS 5.x it works.
I am using xCode 4.3.3 and my configurations are:
Architectures: Standard (armv7) (also tried armv6,armv7 to no avail)
Base SDK: Latest iOS (iOS 5.1)
Valid Architectures: armv6, armv7
Deployment Target: iOS 4.0
What do you think?
In your Xcode preferences, go to downloads tab and install "iOS 4.0 - 4.1 Device Debugging Support".
This package includes information and symbols that Xcode needs for
debugging your app on iOS devices running versions of iOS prior to iOS
4.2. If you intend to debug your app on a device running one of these versions of iOS you should install this package.

iphone simulator not starting

Freshly installed xcode 4.2 on snow leopard and my system profile reads:
Version: 4.2 (4C199)
Location: /Developer
Applications:
Xcode: 4.2 (828)
Instruments: 4.2 (4233)
Dashcode: 3.0.2 (336)
SDKs:
Mac OS X: 10.6: (10K549)
iPhone OS: 5.0: (9A334)
iPhone Simulator: 5.0: (9A334)
My apps work fine on the device but not on the simulator. Message on the xcode reads "Running on iPhone 5.0 simulator" but simulator's status is "Application not responding". I even tried reinstalling xcode/sdk (--mode=all) but no luck.
I'm sure the problem is not with the app because the simulator doesnt respond even when I start it directly without xcode.

How to develop for iPhone OS 3.1.2?

Strange thing happened: My old 2.2.1 version iPod works perfectly with Xcode. Now I got a new one with 3.1.2 installed. Xcode complains that it can't develop for 3.1.2, but instead it can do so for:
Xcode Supported iPhone OS Versions
3.1.1 (7C145)
3.1 (7C144)
3.0.1 (7A400)
3.0
2.2.1
2.2
2.1.1
2.1
2.0.2 (5C1)
2.0.1 (5B108)
2.0 (5A347)
2.0 (5A345)
Now what can I do about it? I have Snow Leopard and Xcode 3.2
You have to update your version of XCode. Go to http://developer.apple.com/iphone/ and download the new SDK.
Sounds like you need the new iphone SDK 3.2 beta available from developer.apple.com today.
