1. From Xcode plugin to Xcode extension
2. About Khoa Pham github.com/onmyway133 github.com/hyperoslo medium.com/@onmyway133
3. It takes 2 iOS developers to start complaining about Xcode
4. XcodeWay
5. Xcode plugin
6. Alcatraz
7. XVim
8. SCXcodeMiniMap

10. ColorSense-for-Xcode
11. Techniques • Private frameworks • Objective C Runtime • LLDB • Swizzling
12. class-dump • IDEKit • DVTKit • Xcode.app/Contents/SharedFrameworks/DVTKit.framework
14. DVTBezelAlertPanel class func swizzleMethods() { guard let originalClass = NSClassFromString("DVTBezelAlertPanel") as? NSObject.Type else { return } do { try originalClass.jr_swizzleMethod("initWithIcon:message:parentWindow:duration:", withMethod: "xmas_initWithIcon:message:parentWindow:duration:") } catch { Swift.print("Swizzling failed") } }
16. DVTSourceTextView func listenNotification() { NSNotificationCenter.defaultCenter().addObserver( self, selector: #selector(handleSelectionChange(_:)), name: NSTextViewDidChangeSelectionNotification, object: nil) } func handleSelectionChange(note: NSNotification) { guard let DVTSourceTextView = NSClassFromString("DVTSourceTextView") as? NSObject.Type, object = note.object where object.isKindOfClass(DVTSourceTextView.self), let textView = object as? NSTextView else { return } self.textView = textView }
17. IDEWorkspaceWindowController self.IDEWorkspaceWindowControllerClass = objc_getClass("IDEWorkspaceWindowController"); NSArray *workspaceWindowControllers = [self.IDEWorkspaceWindowControllerClass valueForKey:@"workspaceWindowControllers"];
18. XcodeGhost
19. Xcode Source Editor extension • Modify contents • Modify current text selection • Seperated process protocol XCSourceEditorCommand { func perform(with invocation: XCSourceEditorCommandInvocation, completionHandler: @escaping (Error?) -> Void) }
20. App Extension • Share • Photo Editing • Today • Finder Sync • Custom Keyboard • File Provider • Document Provider
21. Resign codesign
22. XcodeColorSense extension ? • No Notification • No UI modification
23. Color literal ! #colorLiteral
24. XcodeWay extension ? • No NSTask • No NSWorkspace • No swizzling
25. AppleScript !
27. • NSUserAppleScriptTask • NSAppleEventDescriptor • ProcessSerialNumber on myOpenFolder(myPath) tell application "Finder" activate open myPath as POSIX file end tell end myOpenFolder
28. App Sandbox
29. Scripts Directory NSApplicationScriptsDirectory
30. macOS Mojave • WWDC 2018 - Your Apps and the Future of macOS Security • NSAppleEventsUsageDescription
