Description

• Swift Pocket Reference not free anymore
• Test-driven iOS Development with Swift not free anymore
• Tizen for Dummies was just a list of changes between two versions of the book. Seems like it was never free. I found another book (Guide to Developing Tizen Native Application) to replace it so that we don't have to let go of a whole subcategory.
• Programming Windows 8 Apps with HTML, CSS, and JavaScript (v1) and Programming Windows 8 Apps with HTML, CSS, and JavaScript (v2, incomplete) were combined to one entry which is the final edition of the ebook.
