Hi friends i am new iphone develo开发者_StackOverflow社区per my project is previous is done in x code 3.2.1 earlier version but presently i was use that project in x code 3.2.1 but this kind of error is occurred what is the reason please help me.

The Error is:

The project “Irehab.x code project was saved with a newer version of X code than this one. This version of X code might or might not be able to open the project. Even if the project can be opened, information might be lost. Do you still want to try opening the project?

If u want to run any application of previous version of xcode in new version then click on project tab and select edit project settings. You get new window in which u change the base sdk type and select latest know ios. After that you again click on project tab then click on edit target settings and again change base sdk settings and set as latest known ios. After that in editor windoe change base sdk simulator. It will work .

It seems that you are trying to open with an older version of Xcode a project that was created (or updated to) a newer version of Xcode.

While you can open a older project with the latest Xcode version, the opposite is not always true and the message is telling you that.

One option you have is trying to use the project as it is (i.e., ignoring the warning you get), and try to fix the issues you have; though, possibly the best option you have is creating the project again with the Xcode version you want to use (i.e., creating an empry project and copy over to it files, nibs, create targets, add frameworks, etc.)
