Apple has finally released Preview 5 of Xcode4. I am very excited and loving it, but it still has a few bugs and Apple recommends sticking to Xcode 3.2.5 if you want to develop apps for the app store. Few of the features that I love in Preview 5:
- Many performance problems with making connections are resolved. In particular, the performance of connecting to the First Responder has been drastically improved.
- C++: Several bugs related to using blocks are fixed.
- Xcode automatically creates schemes for all targets in a project when you open an Xcode 3.x– based project. It doesn’t skip targets that other targets depend on.
- When you create NSManagedObject subclasses from entities in a Core Data data model, Xcode ask for confirmation before overwriting existing files.
Can’t wait for the Xcode4 final version! I am working on a nice app which is to be released in early February, and would love if Xcode4 is here by that time.
