It's a small thing, but every time I open my current Xcode project the default iOS device to run my app on is my phone. Is there a way to change it to one of the simulators? i.e. iPhone Pro 11?

SwiftUI Preview Don't work. Progress Preparing iPhone Simulator for Previews. SwiftUI Xcode version 13.0 macOS Big Sur version 11.6

In Xcode 13, using the 14.5 and 15.0 simulators, when I use UserDefaults to save preferences for the user, the defaults seem to go away when the app quits (I am using the home button / app switcher / slide up gesture to quit the app in the simulator). This problem does not occur when using my actual devices (iPad and iPhone). [userDefaults synchronize] returns YES, however I am getting nil for the key I saved upon next launch. Note: I am using NSKeyedArchiver archivedDataWithRootObject with requiresSecureCoding set to YES for some keys, however the first key is not using NSKeyedArchiver and is also returning nil.

When I run an app that uses location services on the Xcode 13.1 simulator for iOS 15 the location privacy settings are missing. If you go to the settings on the simulator under privacy the section for location services is missing. The exact same thing on a physical iPhone running iOS 15.0 does show the location settings under privacy in the settings app. Where did the settings for location privacy go? In order to test using the simulator a developer needs to be able to turn those settings on and off, like turning off precise location to see how an app responds.

Hello , I have a problem of Xcode Simulator Download, Xcode 13.0 successful installed, Macbook OS 12.0.1; got an Apple developer Account with my user name and password, free account; I go to components, and I want to download Simulator IOS 14.5; but after a long time of waiting, I got the above error message, "Xcode could not download and install simulator,... , kCFErrorDomainCFNetwork error 303.; I also tried to use sudo /Applications/Xcode.app/Contents/MacOS/Xcode , but still the same error; What happened and how to solve this problem? thank you!

Hi, I've activated the option "Show device mask in screenshots and videos" in iOS Simulator's preferences. When I take a screenshot of the simulator, using the "Save Screen" button, the "preview" of the screenshot (the one that appears as a small image on MacOS, next to the simulator) shows the frame, but when I save the image, e.g. in the Desktop folder, the frame doesn't appear in the saved image. Am I missing something, or this feature has a bug?

Hello, I have a probelm with the Xcode Simulator not showing desired changes with text font at specific configuration. When the configuration of a UIButton text was set as below on the editor, althought the changes were viewable on storyboard, the simulator didn't look the same. Type:Custom Style: Plain Title:Attributed Is there a logical reason why this happens? Also, the documentation says "Plain" indicate the text is a plain String object whilst "Attributed" indicate the string has become a instance of NSAttributedString. How is it possible to set the style and the title different like Style: Plain/Title: Attributed and vise versa? Maybe this was the reason the simulator didn't work alright? Thank you in advance

MacBook Pro 2018 mid 13.3" Xcode 13.3 Mac OS Monterey 12.3 I had the kernelpanic bellow three time today. I had Xcode with simulator running all times. Have anyone this issue? kernel panic

My version of Xcode was recently updated to 13.3. Now, I can not launch any simulator. I get an "Unable to Boot the Simulator" error from any iOS 15.4 device. I have deleted all 15.4 devices, and am downloading 15.2 devices to test. Some other sources are reporting this, too, but I saw nothing on the Developer Forums so thought I'd open a question here. Hoping for speedy resolution so I don't have to use Android emulators :(. (I develop on Flutter, which is cross platform)

I would like to use(or emulate) a virtual USB drive which behaves as a physical USB drive. Using this, I could try to mount/unmount the Virtual USB and copy(or modify) required files and folders into that(similar to physical USB drive activity). Is there a way to get or implement this in MacOS(BigSur) system? Could anyone please confirm.  If yes, how this can be achieved.

Hello When I open CarPlay Simulator and connect the phone, it gives the following error: Accessory is not Supported Mac Mini MacOS 12.4 with iPhone 13 Pro iOS 15.5 Does anyone have a solution?

I've downloaded Apple's metal simulator example from here https://developer.apple.com/documentation/metal/supporting_simulator_in_a_metal_app and tried simulating an iphone 11 with 11.5 and 12 using iOS, and iPad 9th gen. I get the error below when running the simulator on all the above devices. -[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5252: failed assertion `Draw Errors Validation Fragment Function(blendFragmentShader): Shader reads texture (prevColor[1]) whose usage (0x04) doesn't specify MTLTextureUsageShaderRead (0x01) The error occurs in the drawBox:rendererEncoder at the code below when boxIndex = 1 for(MTKSubmesh *submesh in _meshes[boxIndex].submeshes)   {     [renderEncoder drawIndexedPrimitives:submesh.primitiveType                  indexCount:submesh.indexCount                   indexType:submesh.indexType                  indexBuffer:submesh.indexBuffer.buffer               indexBufferOffset:submesh.indexBuffer.offset];   } I'm using a Macbook pro, macos 12.2 and Xcode 13.3. I hoped that this example would be an easy way to get experience with metal, but I've not got the experience I need to interpret what I should change to address the "doesn't specify MTLTextureUsageShaderRead" error. Any help is greatly appreciated.

Does anyone know how to rid of this message? It is happening every time I build a project using the simulator with the following versions: xCode 13.4.1 mac Monterey 12.4. I didn't see this behavior in Xcode's previous versions. The issue seems to be because it is adding a new application every time I build the project into the firewall app list. (image below) Any tips on how to fix this?

I'm testing network loss handling in my app on the simulator. Turning WiFi OFF triggers pathUpdateHandler with .unsatisfied status. Turning WiFi back to ON triggers pathUpdateHandler with .unsatisfied status again. I noticed that pathUpdateHandler is triggered right after I enabled WiFi, but before WiFi actually connects to the network. When the laptop is actually connected to the WiFi network - pathUpdateHandler isn't triggered, so my app stays in "offline" mode permanently. networkMonitor.pathUpdateHandler = { [weak self] path in guard let self = self else { return } DispatchQueue.main.async { if path.status == .satisfied { self.status = .connected } else { print(path.unsatisfiedReason) self.status = .disconnected } } } monitor.start(queue: queue) networkMonitor is retained by my DIContainer

Noticing that the simulator is often in some state that requires it to Quit and restart it. I often do this: CMD+R to run. Make changes. CMD+R to run (overwrite the existing session). The app (kinda) quits, but the screen is completely black. Like the app hasn't completely quit. The result is that Xcode just constantly says "Launching [App]...". And I have to quit the simulator.

Every time my app runs in the simulator I see this error: Warning: Error creating LLDB target at path '/Users/aaronsmith/Library/Developer/Xcode/DerivedData/Babylist-ahvzjxxrpawwqhecszqeyvjstfca/Build/Products/Debug-iphonesimulator/Babylist.app'- using an empty LLDB target which can cause slow memory reads from remote devices: the specified architecture 'arm64--' is not compatible with 'x86_64-apple-ios13.2.0-simulator' in '/Users/aaronsmith/Library/Developer/Xcode/DerivedData/Babylist-ahvzjxxrpawwqhecszqeyvjstfca/Build/Products/Debug-iphonesimulator/Babylist.app/Babylist' What is this? I'm on an M1, no build issues. It makes me think the simulator is running under rosetta with x68_64. But I didn't choose to do that. Mac OS Ventura. Xcode 14 RC.

One of the two will be used. Which one is undefined.

Hello, I'm new to iOS development and I'm trying to take some screenshots of my app to submit to the App Store. I'm running Ventura 13.0.1 and XCode 14.1. So far I've used these simulators to take screenshots: 6.5 inch - iPhone 11 Pro Max 6.7 inch - iPhone 14 Pro Max 12.9 inch - iPad Pro 6th gen What I'm stuck on is getting the 5.5 inch screenshots, which are required for App Store submission. As far as I can tell from some online searching, the latest iPhone with that screen size was the 8 Plus. I've installed the oldest iOS simulator that XCode has listed (iOS 13.7), but it still won't let me run a simulator for the iPhone 8 Plus to get those screenshots. I don't have the physical device to take screenshots on. Does anyone know how to get the 5.5 inch screenshots without having to manually resize them?

Hi, I'm facing the issue for building the project for Simulator on M1 Mac. One of the suggested solutions was to enable Validate Workspace in project's Build Settings, but it seems it's not available in Xcode 14 anymore. Any suggestions?
