The software was made available for free to all registered members of the $99 per year Mac Developer program and the $99 per year iOS Developer program. It was also sold for $4.99 to non-members on the [[Mac App Store]] (no longer available).  Xcode 4.0 drops support for many older systems, including all PowerPC development and [[software development kit]]s (SDKs) for Mac OS X 10.4 and 10.5, and all iOS SDKs older than 4.3.  The deployment target can still be set to produce binaries for those older platforms, but for Mac OS platforms, one is then limited to creating [[x86]] and [[x86-64]] binaries. Later, Xcode was free to the general public. Before version 4.1, Xcode cost $4.99.<ref>{{cite web|url=http://appleinsider.com/articles/11/07/20/apple_makes_xcode_free_to_all_with_release_of_4_1_on_mac_app_store.html |title=Apple makes Xcode free to all with release of 4.1 on Mac App Store |publisher=[[AppleInsider]] |date=July 20, 2011 |access-date=July 3, 2013}}</ref>
