https://bugs.webkit.org/show_bug.cgi?id=249436 rdar://103410333 Reviewed by Brady Eidson. This adds a sandbox profile for webpushd on iOS. It allows standard system operations, reading and writing to the PushDatabase, interacting with apsd, and interacting with LaunchServices. For now, the sandbox defaults to allowing all operations with symbolication, but we'll change the default to deny once we're sure these rules are sufficient. * Source/WebKit/DerivedSources-input.xcfilelist: * Source/WebKit/Resources/SandboxProfiles/ios/com.apple.WebKit.webpushd.sb.in: Added. * Source/WebKit/Scripts/process-entitlements.sh: * Source/WebKit/WebKit.xcodeproj/project.pbxproj: Canonical link: https://commits.webkit.org/258033@main
