Posting this again so I can include the image. I think I've found it. Quite possibly my project includes some legacy code or otherwise... i.e. Intel based. I'll have to look into that. under the PRODUCT menu, go down to DESTINATION. I had to change the Destination Architectures to Show Both. After doing this "My Mac (Rosetta)" was then showing back in Product --> Destination from the dropdown menu.

I've got the same error. macOS App. and I've tried to build and run on Apple Silicon. I don't see "My Mac" as an option - only "Any Mac (Intel)"... which of course this mac is an M2. the build architectures include Apple Silicon. There must be some setting I have missed. Oh... BTW, I have created a new app from scratch (i.e. built in default) and it builds and runs successfully. So it must be something misconfigured my legacy app.

I believe I have my code working again.For the record I had edited the Options... and removed two relating to iCloud. I had to put those changes back in again. options = @{NSMigratePersistentStoresAutomaticallyOption: @YES, // Key to automatically attempt to migrate versioned stores NSInferMappingModelAutomaticallyOption: @YES, // Key to attempt to create the mapping model automatically NSPersistentStoreUbiquitousContentNameKey: @"my_DataStore", // Option to specify that a persistent store has a given name in ubiquity. NSPersistentStoreUbiquitousContentURLKey: icloudURLForLogs, // Option to specify the log path to use for ubiquitous content logs. NSPersistentHistoryTrackingKey: @YES };- David

I've got the same issue. Were you able to resolve this?- David

The code below is for macOS, iOS should be the same. I'm using this to detect a camera being plugged into a Mac. mDeviceBrowser = [[ICDeviceBrowser alloc] init]; mDeviceBrowser.delegate = self; mDeviceBrowser.browsedDeviceTypeMask = ICDeviceLocationTypeMaskLocal|ICDeviceLocationTypeMaskRemote|ICDeviceLocationTypeMaskShared|ICDeviceLocationTypeMaskBluetooth|ICDeviceTypeMaskCamera; // ICDeviceLocationTypeMaskLocal = 0x00000100, // ICDeviceLocationTypeMaskShared = 0x00000200, // ICDeviceLocationTypeMaskBonjour = 0x00000400, // ICDeviceLocationTypeMaskBluetooth = 0x00000800, // ICDeviceLocationTypeMaskRemote = 0x0000FE00 [mDeviceBrowser start];To see all of this in full flight, take a look at the mac sample app for this called CameraBrowser.https://developer.apple.com/library/archive/samplecode/CameraBrowser/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007761https://developer.apple.com/library/archive/samplecode/SimpleCameraBrowser/Introduction/Intro.html#//apple_ref/doc/uid/DTS40009232I found two sample apps...Hope that helps.- David

Update.I have subsequently performed a build for 10.15... this has changed the behaviour of the application and deviceDidBecomeReady: is now called.2019-11-10 20:15:41.988835+1300 Moments[39041:357763] deviceDidBecomeReady: ICCameraDevice <0x10065c160>: delegate : <0x600003901110> deviceRef : 0x10000035 connectionID : 0xe3440b0c deviceID : 0x0200000c name : Canon EOS Kiss X6i locationDescription : ICDeviceLocationDescriptionUSB iconPath : /System/Library/Image Capture/Support/Icons/GenericCamera.png softwareInstallPercentDone : 100.000000 modulePath : /System/Library/Image Capture/Devices/PTPCamera.app moduleVersion : (null) moduleExecutableArchitecture : 0 type : 0x00000101 UUIDString : 00000000-0000-0000-0000-000004A9323B persistentIDString : 00000000-0000-0000-0000-000004A9323B autolaunchApplicationPath : capabilities : ICCameraDeviceCanTakePictureUsingShutterReleaseOnCamera ICCameraDeviceCanTakePicture ICCameraDeviceCanDeleteOneFile ICCameraDeviceCanAcceptPTPCommands shared : NO transportType : ICTransportTypeUSB usbLocationID : 0x14500000 usbProductID : 0x323b usbVendorID : 0x04a9 usbIntefaceClass : 0x00 usbInterfaceSubClass : 0x00 usbInterfaceProtocol : 0x00 timeOffset : 0.000000 hasConfigurableWiFiInterface : N/A isAccessRestrictedAppleDevice : NOThe call to "requestTakePicture" seems to have no affect.

I've just changed my minimum OS from 10.11 to 10.12This altered the behavious of the software running under 10.15 and caused the session for the device be to opened!I still cannot take a picture from the Mac, but it's a big step forward. I have subsequently increased the min OS version to 10.15... there's not change in picture taking behaviour.Anyway I thout that the feedback was worthwhile providing.- David

I have the same issue on 10.15.2 Beta (19C32e)My software works under 10.14@erobin> it seems to work as if a session is opened correctlyWhat do you mean by this? Is there a different way to open a device?- David
