DTXcodeBuild is the wrong value to use

[davedelong]

👋 Just watched your video on modding Xcode, where you talk about using DTXcodeBuild for determining plugin compatibility.

DTXcodeBuild does not describe the build version of that Xcode. It describes the version of Xcode used to compile that app. All compiled applications have a DTXcodeBuild value in their Info.plist.

If you want Xcode's actual build value, that's in its Contents/version.plist under the ProductBuildVersion key. (This explains the discrepancy between the value in the Info.plist and the value on xcodereleases.com)

Hopper seems to think you can get this value from -[NSProcessInfo xcodeProductBuildVersion], courtesy the DevToolsSupport framework.

🤦 Hi Dave! Thanks for reporting this, I should have recognized the key — serves me right for rushing to support Xcode 15.3 midway through this project.

Just added #2 to support ProductBuildVersion. Great tip on xcodeProductBuildVersion too — thanks for digging it up! Appreciate both the initial report and direction — thank you again!
