Reference to ' ' is ambigous error in Xcode

Question

I was working with a custom iOS framework project in Xcode.There I am getting a lot of errors mentioning "Reference to ' ' is ambigous".I am attaching the screenshot of errors.Please help me correcting this.

Answer 1

Adding more information to Jason's answer.

The error message makes me think you have two declarations of the same library functions. All of those references are from UIKit

mostly this can be occurring because of the header files. As you can see all the errors indicates that it is quoting the enum values. Enum values will always be in the .h files. Normally the reference headers(.h files) will be present inside the frameworks. It is a common mistake that sometimes these header files will be buried some where in our code by any third party frameworks. So kindly check your third party libraries.

I did face this issue once and after searching everywhere i could not able to find the solution. The only thing solved my issue was

Opening a fresh project and importing my files into that project. Actually it really took me less than 10 minutes to move to a new project and immediately my xcode was happy. This is definitely worth a try.

Answer 2

Actually This error was cleared when I shift from iOS SDK 6.1 to 7.1(or any version higher that 6.1)
