Nothing leaves you feeling like a stroke victim more than doing something you know you've done before and having it fail all over the place.
I'm trying to create a simple application with a dummy photo extension written in swift. I have already written an actual application with a photo extension and that works (as well as it can given the occasional nondeterministic behavior we and others have been seeing). To make this demo app, made a new single-view application in Xcode. Then I add a photo extension target, making sure to select Swift as the language. Then I make sure to go tell the application target that "Embedded content contains swift code" because otherwise the photo extension will fail at runtime with the *wildly misleading* and unhelpful error message: "blah blah blah swiftrelated.dylib blah:image not found" (not, in fact, referring to the image the photo extension has been asked to load). Then I delete the Main.storyboard because I don't like storyboards. Then I edit the info.plist created for the extension to remove the NSExtensionMainStoryboard key and replace it with an NSExtensionPrincipalClass key. Then I run the photo extension target in the Photos app. Upon selecting a photo and attempting to edit it with my new extension, I get this error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** setObjectForKey: object cannot be nil (key: <__NSConcreteUUID 0x7ffdd3f12c60> 21074A67-F7EF-423D-A245-8805C0CC134F)' *** First throw call stack: ( 0 CoreFoundation 0x0000000109d843f5 __exceptionPreprocess + 165 1 libobjc.A.dylib 0x000000010b8f1bb7 objc_exception_throw + 45 2 CoreFoundation 0x0000000109c8af18 -[__NSDictionaryM setObject:forKey:] + 968 3 libextension.dylib 0x000000010b8b217a -[_NSExtensionContextVendor _setPrincipalObject:forUUID:] + 114 4 libextension.dylib 0x000000010b8b1880 __105-[_NSExtensionContextVendor _beginRequestWithExtensionItems:listenerEndpoint:withContextUUID:completion:]_block_invoke + 822 5 libdispatch.dylib 0x000000010cdd0c06 _dispatch_call_block_and_release + 12 6 libdispatch.dylib 0x000000010cdeaaf4 _dispatch_client_callout + 8 7 libdispatch.dylib 0x000000010cdd62e9 _dispatch_main_queue_callback_4CF + 490 8 CoreFoundation 0x0000000109cec569 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ + 9 9 CoreFoundation 0x0000000109caf46b __CFRunLoopRun + 2043 10 CoreFoundation 0x0000000109caea06 CFRunLoopRunSpecific + 470 11 GraphicsServices 0x000000011008a9f0 GSEventRunModal + 161 12 UIKit 0x000000010a60e550 UIApplicationMain + 1282 13 libxpc.dylib 0x000000010d0e3b4b _xpc_objc_main + 416 14 libxpc.dylib 0x000000010d0e5ee0 xpc_main + 185 15 Foundation 0x000000010a3311d1 service_connection_handler + 0 16 PlugInKit 0x000000010960fba2 -[PKService run] + 521 17 PlugInKit 0x000000010960f867 +[PKService main] + 55 18 PlugInKit 0x000000010960fbc6 +[PKService _defaultRun:arguments:] + 17 19 libextension.dylib 0x000000010b8bfcdd NSExtensionMain + 51 20 libdyld.dylib 0x000000010ce1b145 start + 1 ) libc++abi.dylib: terminating with uncaught exception of type NSException Well, the ONLY reference to this that I can find is that some framework isn't being implicitly loaded and is dying here. See http://www.atomicbird.com/blog/ios-app-extension-tips at the section titled "Enabling modules might not work as expected" I have literally been pulling my hair out for two hours because I can't get my boilerplate to work and I was actually trying to make a useful demo project, not just bash my head against the same wall (not to mention the hour that I spent trying to get Xcode to NOT build swift successfully when it had copy-pasted Objective-C in it that was clearly not correct [which required me to restart my entire computer]). What am I doing wrong that I need to do right? -- Daniel Blakemore Pixio Software _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
