Earlier today Apple released OSX Yosemite developer preview version 6, along with a beta version of the new Xcode developer tools. However, after users downloaded it, they found that the new Xcode beta version could not be used, so Apple temporarily removed it from the developer website. However, the problem seems to have been resolved, because the latest Xcode beta version currently appears on the Apple developer website. Judging from the version number, the newly released Xcode beta version is indeed newer than the version released earlier today. The Xcode beta version contains Mac and iOS development tools, including the Swift programming language recently launched by Apple at the WWDC conference in June this year. But what is very unexpected is that this year Apple provides this tool to any user who needs to use the Xcode6 beta version, regardless of whether the user has a paid developer account with Apple. Users who need this testing tool can download (enter) it from Apple’s official website.
