iOS camera: detect QR code with vCard 4.0

Hello.I have a problem with the built-in QR code detection of a vCard 4.0 in iOS.As described in https://tools.ietf.org/html/rfc6350 vCard Version 4.0 is always encoded with UTF-8. But it seems that the built-in QR code reader of iOS isn't able to decode the special characters correctly. Or am I missing something?Here is an example. Encode it with any QR code generator in the Internet and point your iOS Camera app at it. You will see that all special characters are not displayed correctly.BEGIN:VCARDVERSION:4.0N:T€st;BjörnORG:ÖÜÄTEL;CELL:+12 (34) 567890ADR:;;Blà St.;Blè Town;;12345;ç-LandURL:https://www.test123.comEMAIL;WORK;INTERNET:test@test123.comEND:VCARD

NSFileProtection confusion

Hello.I have an CoreData app that explicitly enables the data protection capability and sets "NSFileProtectionComplete" in the entitlements. However, if I check the file attributes on the 3 files of the sqlite database I see that these are set to "NSFileProtectionCompleteUntilFirstUserAuthentication" The parent directory ("Application Support") is correctly set to "NSFileProtectionComplete". What am I missing?BRBjörn

Xcode can't sign apps anymore

Today I updated to Xcode 10.1 (Build 10B61). Now I cannot run a single app in Debug mode on my devices. I always get the following error:/usr/bin/codesign --force --sign ... --verbose /Users/.../AppName-ejqufizhohhqtsfbcwkjvtmownxv/Build/Products/Debug-iphoneos/AppName.app/Frameworks/libswiftDispatch.dylib error: The specified item could not be found in the keychain.If I run the exact same command in the Terminal it shows no errors at all.If I run the command security find-identity -p codesigningthen I see the identity and it shows that the identity is valid. What happend to Xcode since the last update and how can I fix it? I already removed access to the identity in Keychain. Xcode asked for permission the next time I tried to run the app on the device. But I still get the same error.BRBjörn
