Overview

for (int i = 0; i < 1000; i++){ double st_tmp = CFAbsoluteTimeGetCurrent(); retBuffer = [self.enhancer enhance:pixelBuffer error:&error]; double et_tmp = CFAbsoluteTimeGetCurrent(); NSLog(@"[enhance once] %f ms ", (et_tmp - st_tmp) * 1000); } When I run a CoreML model using the above code, I notice that the runtime gradually decreases at the beginning. output： [enhance once] 14.965057 ms [enhance once] 12.727022 ms [enhance once] 12.818098 ms [enhance once] 11.829972 ms [enhance once] 11.461020 ms [enhance once] 10.949016 ms [enhance once] 10.712981 ms [enhance once] 10.367990 ms [enhance once] 10.077000 ms [enhance once] 9.699941 ms [enhance once] 9.370089 ms [enhance once] 8.634090 ms [enhance once] 7.659078 ms [enhance once] 7.061005 ms [enhance once] 6.729007 ms [enhance once] 6.603003 ms [enhance once] 6.427050 ms [enhance once] 6.376028 ms [enhance once] 6.509066 ms [enhance once] 6.452084 ms [enhance once] 6.549001 ms [enhance once] 6.616950 ms [enhance once] 6.471038 ms [enhance once] 6.462932 ms [enhance once] 6.443977 ms [enhance once] 6.683946 ms [enhance once] 6.538987 ms [enhance once] 6.628990 ms ... In most deep learning inference frameworks, there is usually a warmup process, but typically, only the first inference is slower. Why does CoreML have a decreasing runtime at the beginning? Is there a way to make only the first inference time longer, while keeping the rest consistent? I use the CoreML model in the (void)display_pixels:(IJKOverlay *)overlay function.

URLSession.shared.downloadTask doesn't work apple watch. I monitored network traffic but it doesn't. have any activity. Data(contentsOf: URL(string: url)!) works perfectly. Also, it works perfectly in preview. What do i do? Ask for more context if necessary.

When I accessed the page "Certificates, IDs, &amp; Profiles", it shows "Unable to find a team with the given Team ID 'XXXXXXXXXX' to which you belong. Please contact Apple Developer Program Support. https://developer.apple.com/support". I confirmed my developer account was paid in 6 months and should be valid. I accessed 2 weeks ago without any problem. This is the screenshot.

Is it possible to initiate an iap flow from App Clips? There's not a clear answer to this in the docs. StoreKit is NOT listed as an unapproved framework for App Clips, but in-app purchases ARE listed as "not recommended" for App Clip functionality. I tried setting up a test with a StoreKit config file on the App Clip in XCode and the products weren't returned but... storekit testing... it would be great to get confirmation on this functionality after the iOS 17 updates.

WindowGroup{ SolarDisplayView() .environment(model) } .windowStyle(.plain) Why is the code above correct while the code below reports an error? How to modify the following code? WindowGroup{ SolarDisplayView() .environment(model) } .windowStyle(model.isShow ? .plain : .automatic)

I uploaded a build to testflight and released it to Internal testers, however when the testers tried downloading the app a alert dialog shows the following: Could not install [App] The requested app is not available or doesn't exist. Also tried to submit it via external testers but getting another error.

Hi, I wanted to use Siri Capability for a WatchOS app, however in xcode on a WatchOS project, the option to add Siri is not present. In an IOS project this is visible but if you are not part of the ADP or ADEP you do not have access to it, this message appears in red if you try to select it as a personal team. I am considering paying to join the ADP but I am unsure if it will unlock the ability to use Siri capability on WatchOS. It looks like it is completely unsupported as it cannot be even selected from the capabilities section in xcode , even though Apple states it is supported under ADP and ADEP on their website. I am a little confused. Does anyone else have this issue, or is Siri present under capabilities for you in a WatchOS project?

Hi everyone, I'm encountering an intermittent issue with my Xcode Cloud CI/CD pipeline when pulling Swift Package Manager (SPM) dependencies from AWS CodeArtifact. The build process occasionally fails with an SSL error, but other times it succeeds without any issues. This inconsistency is causing significant disruption to our continuous integration process. Environment: Xcode Cloud Swift Package Manager (SPM) for dependency management AWS CodeArtifact as the package registry Error Message: Error: registry login using https://xx-xx-xx.codeartifact.eu-central-1.amazonaws.com/swift/***/login failed: The certificate for this server is invalid. You might be connecting to a server that is pretending to be "xx-xx-xx.codeartifact.eu-central-1.amazonaws.com" which could put your confidential information at risk.. Would you like to connect to the server anyway?

We currently have a PacketTunnelProvider providing VPN to managed devices. Our profile locks this down with OnDemandEnabled and OnDemandUserOverrideDisabled set to true. We've received some reports that on device startup, there is a time period after Wi-Fi connects but before the OnDemand VPN kicks in to enable our VPN, where users are able to navigate to IPs that are meant to be captured by the VPN tunnel. Instead, they are able to reach these IPs directly during this time period. Is there an expectation in regards to when OnDemand VPN is allowed to kick in to enable the VPN? Is there anything that we can do to minimize this delay?

I'm working on an Angular application that retrieves static data (JSON, MP3, and images) from a backend server, with a cache control response header set to Cache-Control: public, max-age=2592000. I expect these files to be served from either disk or memory cache after the initial request. However, in Safari, the browser sometimes fetches the data from the cache and other times makes a network call. This inconsistent behavior is particularly noticeable with MP3 files, whereas JSON and image files are consistently served from the cache as expected. I've tested this on multiple Safari versions and observed the same issue: Version 17.2 (19617.1.17.11.9) Version 17.1 (19616.2.9.11.7) Version 17.3 (19617.2.4.11.8) I confirmed that the "Disable Cache" option is not enabled in the developer tools, so the MP3 files should be cached. This functionality works correctly in Chrome and Firefox without any issues.

In the past, Apple recommended restricting USDZ models to a maximum of 100,000 triangles and a texture sizes of 2048x2048 for Apple QuickLook (and I think for RealityKit on iOS in general). Does Apple have any recommended max polygon counts for visionOS? Is it the same for models running in a Volumetric window in the shared space and in ImmersiveSpace? What is the recommended texture size for visionOS? (I seem to recall 8192x8192, but I can't find it now)

I faced a problem during development that I could not scan Code39 barcode with iPad using Vision. A sample label I used for test has multiple Code39 barcode on it and I could scan almost all barcodes except for specific one. And when I use conventional barcode scanner and free apps to scan barcode, I could scan the barcode with no problem. I failed to scan the barcode only when I use Vision function. Has anyone faced similar situation? Do you know the cause why specific barcode could not be scanned with iPad with Vision?

Hi, I face a problem that I could not scan a specific Code 39 barcode with Vision framework. We have multiple barcode in a label and almost all Code 39 can be scanned, but not for specific one. One more information, regardless the one that is not recognized with Vision can be read by a general barcode scanner. Have anyone faced similar situation? Is there unique condition to make it hard to scan the barcode when using Vision?(size, intensity, etc) Regards,

I built a custom binary which requires elevated privileges to execute. I wrote a launchd plist file and loaded it. On loading , the app is working as expected but lot of apps were corrupted. Apps like chrome, slack, zoom etc became un openable . Even my mouse right click stopped working. When I looked at the contents of the chrome in application directory it was missing few files. contents of chrome before launching my custom app -rw-r--r--@ 1 myusername admin 2556 May 14 16:49 CodeResources drwxr-xr-x@ 3 myusername admin 96 May 14 15:59 Frameworks -rw-r--r--@ 1 myusername admin 11851 May 14 16:17 Info.plist drwxr-xr-x@ 3 myusername admin 96 May 14 15:59 Library drwxr-xr-x@ 3 myusername admin 96 May 14 16:17 MacOS -rw-r--r--@ 1 myusername admin 8 May 14 15:59 PkgInfo drwxr-xr-x@ 61 myusername admin 1952 May 14 15:59 Resources drwxr-xr-x@ 3 myusername admin 96 May 14 16:17 _CodeSignature -rw-r--r--@ 1 myusername admin 12551 May 14 15:59 embedded.provisionprofile contents of chrome after launching my custom app drwxr-xr-x@ 3 myusername admin 96 May 14 15:59 Frameworks drwxr-xr-x@ 3 myusername admin 96 May 14 15:59 Library drwxr-xr-x@ 2 myusername admin 64 May 16 13:48 MacOS drwxr-xr-x@ 58 myusername admin 1856 May 16 13:48 Resources drwxr-xr-x@ 2 myusername admin 64 May 16 13:48 _CodeSignature my custom app plist file &lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt; &lt;plist version="1.0"&gt; &lt;dict&gt; &lt;key&gt;Label&lt;/key&gt; &lt;string&gt;com.zzzz.xxxx&lt;/string&gt; &lt;key&gt;Program&lt;/key&gt; &lt;string&gt;/path/to/app&lt;/string&gt; &lt;key&gt;RunAtLoad&lt;/key&gt; &lt;true/&gt; &lt;/dict&gt; &lt;/plist&gt; If i run my custom app as a standalone process everything works as expected, no corruption or data loss.

Hello, financial reports for April 2024 are ready since the beginning of May in AppStore connect but the “Expected payment date“ is not present in the top right of the page. Anyone facing the same issue? Do you know the reason for that?

I'm currently supporting an app where one of the dependencies we use had an update. The app is an iPad only app that is meant to be run as a kiosk (guided access, single app mode). After the dependency update for the casing of the tablet / kiosk, we noticed an uptick in errors that may or may not have been associated with the recent 3rd party software update. I wanted to verify if the update had an impact on our production kiosks. To get a good idea of whether or not the update for casework's library had a negative impact, though, I would need to run instruments on a tablet while it's in the case. There's only one power cable to the iPad and the cable that would be used to connect directly to a Mac / Xcode is the same cable that connects to the casework. Is it possible to run instruments, and then retrieve data, from an app that's not directly connected to Xcode? Or is it possible for Xcode to somehow connect via a running instance of an app remotely?

Hello everyone, I have been receiving this same crash report for the past month whenever I try and export a Final Cut Pro project. The FCP video will get to about 88% completion of export, then the application crashes and I get the attached report. Any leads on how to fix this would be greatly appreciated! Thank you. -Lauren

I've read the definitive "Recording Private Data in the System Log" by @eskimo and the words at man 5 os_log and written code to, specifically, turn on "Enable-Private-Data" in my app. My application is a command line and I've configured Xcode to insert what I believe to be the appropriate incantations in an Info.plist file into the unstructured executable binary. When I run the app with Terminal, I see <private> output in the Console app where I expect values to be displayed in a public manner. Nothing I've read says that <key>Enable-Private-Data</key><true/> doesn't apply to command line apps, and my own understanding of the value of of the logging mechanism rejects that notion because logging is performed all over macOS, not just in a ***.app environment. A this point, I'm firmly convinced this unexpected behavior is of my own doing, but I have paused the search for my (probably embarrassing) mistake, to write this note because of a 1% doubt I'm wrong. I'd be very happy to receive the, expected, assurance that logging configuration via an embedded Info.plist in a command line app does influence logging behavior. With that assurance, I'll know it's my problem and I'll search/find/fix. On there way there, I'll create the simplest command line app that exhibits this anomaly -- which will likely reveal my error and, if not, it'll be fodder for a bug report. Embedding an Info.plist into a command line app is a tad out of the ordinary but I've done it before (using Xcode or SPM) to carry knowledge into a CLI via a mainBundle.infoDictionary .. and in the particular case described above, I've printed that infoDictionary to show the successful embedding, viz: . . . . "OSLogPreferences": { "com.ramsaycons" = { "DEFAULT-OPTIONS" = { "Enable-Private-Data" = 1; }; }; }, . . . . Sonoma 14.5 / Xcode 15.4 / MBP (Apple M1 Max)

Hi In my app I've to complete the IDV [Identity verification] by capturing the face os user and his/her documents, for this the backend developer provides me the URL from the IDV 3rd party, which URL I do open in webview, so before during loading the camera captureing screen in webview the Live Broadcast screen pops up from no where. I don't want this Live Broadcast screen but somehow it opens anyway. Although it is good thing that my expected camera screen was still open in background so I can go further from there. First time I'm also bit confused like how this kind of screen popsup even if I did't code for it. Also it takes me a little bit time to figure out how to close that screen. Simple peoples/users who're going to use my app they don't know how to close it. Please check the screenshots I attached. Please help me to rid of this popup. Thank You

I have a sample iOS app in Xcode that I run in the iOS 17.5 Simulator. It creates a WKWebView and configures a proxy via the ProxyConfiguration API, it works as expected unless the proxy tries to establish mTLS. It seems there is no way to handle the client certificate request when using a proxy. If I navigate to a page that requests mTLS without a proxy configured, it works as expected. Here is a minimal repro: #import "ViewController.h" #import &lt;WebKit/WebKit.h&gt; @import Foundation; @import WebKit; @interface ViewController () &lt;WKNavigationDelegate&gt; @property (nonatomic,strong) WKWebView* webView; @property (nonatomic, strong) WKWebViewConfiguration * webConfig; @end @implementation ViewController - (void)loadView { [super loadView]; nw_protocol_options_t tls_options = nw_tls_create_options(); sec_protocol_options_t sec_options = nw_tls_copy_sec_protocol_options(tls_options); sec_protocol_options_set_challenge_block( sec_options, ^(sec_protocol_metadata_t metadata, sec_protocol_challenge_complete_t challenge_complete) { NSLog(@"Inside of challenge block"); challenge_complete(nil); }, dispatch_get_main_queue()); nw_endpoint_t proxy_endpoint = nw_endpoint_create_host(GetHost(), GetPort()); nw_relay_hop_t relay = nw_relay_hop_create(nil, proxy_endpoint, tls_options); nw_proxy_config_t proxy_config = nw_proxy_config_create_relay(relay, nil); nw_proxy_config_add_match_domain(proxy_config, "api.ipify.org"); self.webConfig = [[WKWebViewConfiguration alloc] init]; self.webConfig.websiteDataStore = [WKWebsiteDataStore nonPersistentDataStore]; self.webConfig.websiteDataStore.proxyConfigurations = @[ proxy_config ]; self.webView = [[WKWebView alloc] initWithFrame:self.view.frame configuration:self.webConfig]; self.webView.navigationDelegate = self; [self.view addSubview:self.webView]; } - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"%s",__func__); NSURL* url = [[NSURL alloc] initWithString:@"https://api.ipify.org"]; NSURLRequest* request = [[NSURLRequest alloc] initWithURL:url]; [self.webView loadRequest:request]; } - (void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation { NSLog(@"%s",__func__); } - (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation withError:(NSError *)error { NSLog(@"%s. Error %@",__func__,error); } - (void)webView:(WKWebView *)webView didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential *))completionHandler { NSLog(@"%s",__func__); NSLog(@"protection space: %@", challenge.protectionSpace.authenticationMethod); completionHandler(NSURLSessionAuthChallengePerformDefaultHandling, nil); } @end The logs for this code show: -[ViewController viewDidLoad] -[ViewController webView:didStartProvisionalNavigation:] -[ViewController webView:didFailProvisionalNavigation:withError:]. Error Error Domain=NSURLErrorDomain Code=-1206 "The server “api.ipify.org” requires a client certificate." If we don't set up the ProxyConfiguration and navigate to a site that requires mTLS, the logs look like this: -[ViewController viewDidLoad] -[ViewController webView:didReceiveAuthenticationChallenge:completionHandler:] protection space: NSURLAuthenticationMethodServerTrust -[ViewController webView:didReceiveAuthenticationChallenge:completionHandler:] protection space: NSURLAuthenticationMethodClientCertificate -[ViewController webView:didStartProvisionalNavigation:] //... Eventually the request fails but the key difference is that didReceiveAuthenticationChallenge was invoked. When using the ProxyConfiguration neither that function nor the block we set via sec_protocol_options_set_challenge_block were run. I also tried to provide the client identity via sec_protocol_options_set_local_identity to no avail, and I've tried configuring these options too but they had no effect sec_protocol_options_add_tls_application_protocol(sec_options, "h2"); sec_protocol_options_set_max_tls_protocol_version(sec_options, tls_protocol_version_TLSv13); sec_protocol_options_set_peer_authentication_required(sec_options, true); Am I missing something? Or is this a bug in the ProxyConfiguration API?
