App crashes on trying to read card ID about mensaguthaben-ios HOT 2 CLOSED

Hi @kiliankoe ,
after installing the latest Xcode update I discover the same problem. But interestingly only in debug mode: this means when I export the app "Ad Hoc" (as .ipa) and install it via Apple Configurator, the app works without crashing. Strange.
The reason seams to be that tag.identifier returns a 7 byte long data value, but you need 8 bytes for a successful conversion to Integer. So my solution is to insert a zero byte into idData. This solution works, it prints out the correct card ID.

if(idData.count == 7) {
    idData.append(UInt8(0))
}

Thanks for reporting!
