Create a new mac os app in Xcode 14. Fetch camera list by these code: NSArray *devicesIOS = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo]; then change the architecture to x86_64 snd add com.apple.security.device.camera to entitlements then this code will cost 4s and UI will be stuck during next half minutes on M1 machine running MacOS 13 This causes a lot of apps stuck at starting like Zoom and Classin How to solve this?

Instruments freeze when WKWebView is created I create a very simple mac os application If I create a WKWebView like this " (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. self.webview = [[WKWebView alloc] initWithFrame:NSMakeRect(0, 0, 500, 500)]; } " Then the instruments freeze when I record allocations Why? If I remove the creation of WKWebView, everything works fine I'm using Xcode 14.2

I created an WKWebView, but it can not load "https://www.baidu.com" and also it keeps calling decidePolicyForNavigationAction function it works well for other website @interface ViewController() @property (nonatomic, strong) WKWebView* webview; @end @implementation ViewController (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. self.webview = [[WKWebView alloc] initWithFrame:NSMakeRect(0, 0, 500, 500)]; [self.view addSubview:self.webview]; self.webview.navigationDelegate = self; NSURL* url = [NSURL URLWithString:@"https://www.baidu.com"]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; [self.webview loadRequest:request]; // [self.webview reload]; } (void)setRepresentedObject:(id)representedObject { [super setRepresentedObject:representedObject]; // Update the view, if already loaded. } (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction preferences:(WKWebpagePreferences *)preferences decisionHandler:(void (^)(WKNavigationActionPolicy, WKWebpagePreferences *))decisionHandler{ decisionHandler(WKNavigationActionPolicyAllow, preferences); }
