Hello, I am experiencing an unexpected issue related to PhotosKit, where an occasional crash is occurring in an area it shouldn't. I've provided the crash log below for reference below: Last Exception Backtrace: 0 CoreFoundation 0x1aa050860 __exceptionPreprocess + 164 1 libobjc.A.dylib 0x1a2363c80 objc_exception_throw + 60 2 CoreFoundation 0x1a9f68218 -[__NSDictionaryM setObject:forKeyedSubscript:] + 1184 3 Photos 0x1c11cb178 -[PHCloudIdentifierLookup _lookupCodeSpecificCloudIdentifierStrings:forIdentifierCode:] + 572 4 Photos 0x1c11cb278 -[PHCloudIdentifierLookup _lookupLocalIdentifiersForIdentifierCode:codeSpecificCloudIdentifierStrings:] + 92 5 Photos 0x1c11cbbec __69-[PHCloudIdentifierLookup lookupLocalIdentifiersForCloudIdentifiers:]_block_invoke + 88 6 CoreFoundation 0x1a9f67d70 NSDICTIONARY_IS_CALLING_OUT_TO_A_BLOCK + 24 7 CoreFoundation 0x1a9f67bec -[__NSDictionaryM enumerateKeysAndObjectsWithOptions:usingBlock:] + 288 8 Photos 0x1c11cbb40 -[PHCloudIdentifierLookup lookupLocalIdentifiersForCloudIdentifiers:] + 488 9 Photos 0x1c125e6e4 -[PHPhotoLibrary(CloudIdentifiers) localIdentifierMappingsForCloudIdentifiers:] + 96 10 Photos 0x1c1104f18 0x1c1101000 + 16152 "exceptionReason" : {"arguments":["-[__NSDictionaryM setObject:forKeyedSubscript:]"],"format_string":"*** %s: key cannot be nil","name":"NSInvalidArgumentException","type":"objc-exception","composed_message":"*** -[__NSDictionaryM setObject:forKeyedSubscript:]: key cannot be nil","class":"NSException"}, The crash can be recreated by calling PHPhotoLibrary.cloudIdentifierMappings(forLocalIdentifiers:) with random identifiers, as demonstrated below: let cloudIdentifiers = (0...10).map { _ in PHCloudIdentifier(stringValue: UUID().uuidString) } let localIdsMap = PHPhotoLibrary.shared().localIdentifierMappings(for: cloudIdentifiers) I've noticed that the method seems to crash consistently when an incorrect cloud identifier is input. This is surprising to me since the return type is [PHCloudIdentifier : Result<String, Error>], so I was anticipating an explicit error. The issue can be reproduced on both Xcode 15.0 & iOS 17.2 and Xcode 14.3.1 & iOS 16.0. While I'm fairly certain that only valid identifiers are used in my app, I would still like to know if there is a potential way to validate a cloud identifier prior to accessing this method?
