An implementation of the classic Minesweeper game. Originally written by me in 1999 and updated for Xcode 8 and macOS Sierra in 2017. For a full (but light-hearted) article on the topic, see Compiling a Mac OS 8 application on macOS Sierra.
NOTE: this project in this article no longer compiles in Xcode 10/macOS 10.14 or newer due to i386 deprecation.
Building this project requires a copy of the Mac OS X 10.6 SDK. The easiest way to get this is to visit the Apple Developer "More Downloads" page and once you've logged in download Xcode 4.3.3 for Lion from Apple (this second link will likely fail unless you've already logged in).
You can't run Xcode 4.3.3 on macOS Sierra but you can open the bundle and copy the "Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk" folder and place it at the same location in your Xcode 8's bundle. To force Xcode to include the 10.6 SDK, you must also edit the "MinimumSDKVersion" in the "Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Info.plist" file in your Xcode bundle to "10.6" or lower.
