This was working a few days ago, but it has since stopped and I can't figure out why. I've tried resetting TCC, double-checking my entitlements, restarting, deleting and rebuilding, and nothing works.
My app is a sandboxed macOS SwiftUI LSUIElement app that, when invoked, checks to see if the frontmost process is Terminal, then tries to get the frontmost window’s title.
func
getFrontmostWindowTitle()
throws
-> String?
{
let trusted = AXIsProcessTrusted()
print("getFrontmostWindowTitle AX trusted: \(trusted)")
guard let app = NSWorkspace.shared.frontmostApplication else { return nil }
let appElement = AXUIElementCreateApplication(app.processIdentifier)
var focusedWindow: AnyObject?
let status = AXUIElementCopyAttributeValue(appElement, kAXFocusedWindowAttribute as CFString, &focusedWindow)
guard
status == .success,
let window = focusedWindow
else
{
if status == .cannotComplete
{
throw Errors.needAccessibilityPermission
}
return nil
}
var title: AnyObject?
let titleStatus = AXUIElementCopyAttributeValue(window as! AXUIElement, kAXTitleAttribute as CFString, &title)
guard titleStatus == .success else { return nil }
return title as? String
}
I recently renamed the app, but the Bundle ID has not yet changed. I have com.apple.security.accessibility set to YES in the Entitlements file (although i had to add it manually), and a NSAccessibilityUsageDescription string set in Info.plist.
The first time I ran this, macOS nicely prompted for permission. Now it won't do that, even when I use AXIsProcessTrustedWithOptions() to try to force it.
If I use tccutil to reset accessibility and apple events, it still doesn't prompt. If I drag my app from the build products folder to System Settings, it gets added to the system TCC DB (not the user DB). It shows an auth value of 2 for my app:
% sudo sqlite3 "/Library/Application Support/com.apple.TCC/TCC.db" "SELECT client,auth_value FROM access WHERE service='kTCCServiceAccessibility' OR service='kTCCServiceAppleEvents';"
com.latencyzero.<redacted>|2

I'm at a loss as to what went wrong. I proved out the concept earlier and it worked, and have since spent a lot of time enhancing and polishing the app, and now things aren't working and I'm starting to worry.
