canOpenURL not working, scheme now must be only lowercase?
In iOS 9 and below it's working perfectly, on iOS 10 canOpenURL return always NO...In my plist I have this:<key>LSApplicationQueriesSchemes</key> <array> <string>easymeetingS</string> </array>From what this output in console:Jan 1 01:02:18 iPad-41-Air-v100 easymeetingOnCall S(UIKit)[374] <Notice>: -canOpenURL: failed for URL: easymeetingS:// - error: This app is not allowed to query for scheme easymeetingsI can deduce that at some point they enforced lowercase on URL schemas, why? Is this bug or permanent modification? I see nowhere in documentation the enforcing of lowercase...

Inquiry About iBeacon Advertising Packet Schemes for iOS Background Wake-up Performance
Hello, I would like to consult Apple’s technical team regarding how different iBeacon Bluetooth advertising packet configurations impact iOS app background wake-up performance. My specific questions are outlined below: We have two available iBeacon advertising configuration schemes: Scheme 1: Encapsulate the non-connectable iBeacon advertising payload and connectable Bluetooth advertising payload into a single advertising packet for transmission. Scheme 2: Split the two types of advertising payloads above into two separate independent advertising packets and broadcast them respectively. Could you please clarify which packet format enables iOS apps to detect and recognize iBeacon devices more reliably and easily, thereby triggering app background wake-up more effectively? I would appreciate it if you could explain the differences, advantages and disadvantages of these two schemes under iOS’s Bluetooth scanning and app wake-up mechanisms, as well as provide your official reco

Reply to Xcode Cloud: How to trigger testing for packages?
I use a workaround: Create a new Xcode project, in the same git repo as your-swift-package, without adding any source code files. Add your-swift-package as a local package to your Xcode project (File-> Add Packages) Add your-swift-package as a dependency to the Xcode project's target (In the Xcode project select the target and add framework as usual) Add the test target of your-swift-package to the test scheme of the project (Open the scheme editor in the Xcode project, in test-phase, info tab, add the test target of your-swift-package to the enabled tests using the '+' button Configure the Xcode project to build in Xcode Cloud I hope that Apple will soon support building stand alone swift packages, so we do not need this additional workaround.

Reply to SKScene Overlay stuck in loop
As a workaround, I recommend that you try running your app with Metal API validation disabled (Click your build target -> Edit Scheme -> Options -> Metal API Validation -> Disabled).Additionally, please file a bug report for this issue using our feedback assistant tool at: https://developer.apple.com/bug-reporting/

Reply to Xcode 12 "Build input file cannot be found" $DERIVED_FILES_DIR
It appears that the build system under Xcode 12 and higher is now validating that any files referenced in the Other Linker Flags (probably other build settings as well before actually building the target. The workaround to the problem is to force the file into existence before the target itself starts to build by touch-ing it prior to the build. The the existing project build phase script can still be used to populate the file before the build gets to the linking stage, the file just has to exist on disk. The Pre-action scripts in build schemes don't really work well for our situation, as we have several schemes that include the build targets. The best solution I've found is to move the generated plist file to a project relative location (instead of in $DERIVEDFILESDIR which is target specific). I then added an Aggregate build target to the actual target's project and made it a dependency of the original build target. This dependency gets built BE

Reply to I could not see my text file at my files
You'll have to specify the path to the file. When you are running in the Xcode debugger, you may be able to specify that in the scheme settings somewhere. Normally these kinds of simple apps are designed to be compiled and run from the command line. In this case watch.txt would be located in the current working directory of wherever your Terminal shell happened to be using at that time.

Widget Extension scheme causes "failed to find valid container bundle" errors when ran
I've got a macOS app with a Widget Extension. When I try to run the scheme attached to this extension, WidgetKit Simulator unexpectedly quits and I get plenty of errors such as the ones below, that do not seem to be at all linked with the purpose nor the functionalities explicitly used by the app (nor the extension). That's what I get in Xcode's console: com.apple.siri.AssistantSettingsControls failed to find valid container bundle for file:///System/Library/ExtensionKit/Extensions/AssistantSettingsControlsExtension.appex/ at /System/Library/ExtensionKit/Extensions/AssistantSettingsControlsExtension.appex com.apple.settings-intents.LoginItemsIntents failed to find valid container bundle for file:///System/Library/ExtensionKit/Extensions/LoginItemsIntentsExtension.appex/ at /System/Library/ExtensionKit/Extensions/LoginItemsIntentsExtension.appex com.apple.SoftwareUpdate.SoftwareUpdateSettingsWidget failed to find valid container bundle for file:///System/Library/ExtensionKit

Reply to xcodeproj and Swift package localization
Thanks, I filed feedback: https://feedbackassistant.apple.com/feedback/7763715 With regards to the recommendation to use xcodebuild. I am aware that I can use xcodebuild to build even platform-specific, e.g. xcodebuild -scheme SomePackage -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 11' build but I was under the impression that Xcode project might still be required in certain situations?!? For example testing may lead to error like the following xcodebuild: error: Scheme SomePackage is not currently configured for the test action. which I don't encounter when building with -project SomePackage.xcodeproj option

Reply to Can't Test StoreKit in Sandbox or Xcode
One thing you can do in Xcode 12 is to test purchases in the simulator, if you set up a StoreKit Configuration file and enable it in the project scheme... Then you can do the full range of purchase testing in the simulator. On device Sandbox should still present a login (make sure your scheme does not have a StoreKit configuration active if you want to test using Sandbox), if you go to Settings->AppStore are you already logged in to a testing account? If you are it would not present a new login. I get the same crash in Xcode using the Transactions window and clicking on manage subscriptions, though Xcode 12.2 seems to have a release candidate now and that might fix things.

Environment Variable? I know in SwiftUI you can: struct SmileyFaceView: View { @Environment(.colorScheme) var scheme var body: some View { Image(systemName: face.smiling) .foregroundColor(scheme == .light ? .black : .white) // this is to change to color according to the scheme .environment(.colorScheme, .light) // This is to force the icon to the face.smily } } for your need not sure in UIKit

Reply to ASWebAuthenticationSession Not Recognizing LinkedIn https Redirect
I faced the same issue. What I have found out is ASWebAuthenticationSession only uses custom URL scheme. I tried with universal link, still does not work. Callback is not happening back to the app. I would suggest you to use WKWebview for http/https scheme or use custom URL scheme.

Reply to XCode: uncaught exception of type NSException on ios 9-10 vs ios 11
Issue was resolved by enabling OS_ACTIVITY_MODE variable. I believe I disabled it in XCode 8 to prevent unwanted output.Select from Xcode menu Product -> Scheme -> Edit Scheme.. Select the Run scheme and look under Arguments. If you see the OS_ACTIVITY_MODE variable checked, deselect it.

Reply to Screenshot iPhone iPad for App Store
It is quite common to use simulator screenshots.View at 100% (even if that means going larger than you can view on your monitor), then use the simulator's menu to capture/save.Crop/resize down as needed via your favorite image editor, then save, being aware of applicable file naming schemes, etc.
