+### IDEWorkspaceChecks
+
+Manage `IDEWorkspaceChecks.plist` files that store workspace check states. Introduced in Xcode 9.3, these files prevent Xcode from recomputing checks each time a workspace is opened.
+
+The primary use is suppressing the macOS 32-bit deprecation warning:
+
+```ts
+import { XCWorkspace, IDEWorkspaceChecks } from "@bacons/xcode";
+
+// Suppress the 32-bit deprecation warning
+const workspace = XCWorkspace.open("/path/to/MyApp.xcworkspace");
+workspace.setMac32BitWarningComputed();
+
+// Or work with IDEWorkspaceChecks directly
+const checks = IDEWorkspaceChecks.openOrCreate("/path/to/MyApp.xcworkspace");
+checks.mac32BitWarningComputed = true;
+checks.save();
+
+// Low-level API
+import * as workspace from "@bacons/xcode/workspace";
+
+const plist = workspace.parseChecks(plistString);
+console.log(plist.IDEDidComputeMac32BitWarning); // true
+
+const output = workspace.buildChecks({ IDEDidComputeMac32BitWarning: true });
+```
