warning: ‘weak_import’ attribute ignored

April 12, 2009 § Leave a comment

Debugging is one of the most undocumented and least discussed topic in Xcode.

Very often you would have to rebuild the project hundreds of time if you make significant changes in project name, ViewController name, etc.

Sometimes you can save time by copy files from existing project by dragging the folders and files to new project. However, it doesn’t work all the times without running into significant errors.

After hours of trials, I discovered AudioTool.framework and AVFoundation.framework don’t like file transferring.

The most troublesome file transfer is CoreLocation.framework. If you are doing complex work on CoreLocation.framework, then it is better to add the framework instead of transferring.

If you don’t you’ll get this warning on console.
