The Objective-C code does not behave as I thought it would. The handling of the IV and the key are not satisfactory. I will have to change the Objective-C code as well as come up with corresponding C# routines. Looks like I have to go to RNCryptor.

you are a good guy! I tried replacing the three lines you did not like with provider.IV = new byte[16] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; However, that did not work. I wrote a corresponding C# Encryption routine to check my C# Decryption routine. The C# routines work well together but do not work with the IOS one. The C# generates/expects 128 bytes while the IOS generates/expects 64 bytes for the same data input. I need to take a closer look at what the IOS routine is doing.

@prince The sample you provided has a default IV built into the sample so it won't work with the data coming from IOS.

What AES.Mode should I be using to be compatible with Objective-C? Where do I get the IV from? My key size is 64 bytes.

It probably was Time Machine. I vaguely remember the external drive being yellow. Now it is green and I have 12 GB available. Xcode 6.3 is listed as being installed but it is no where to be found on my system. However, it is showing up as available for install. I will try installing it again.

Yes, I use Time Machine for backup. It goes to my external drive and it is connected.

comment Xcode: How do I tell where a warning is coming from?
Yes. Turns out that the problem is a bug in iOS 8. It can be triggered by clicking on a date widget in Safari.
