Unity 5.5 (Blur Optimized) broken for iOS?

Hello

I'm running 5.5f1 and I've also tried 5.5p1, but blur optimized fails to compile when building for iOS (in Xcode).

See below :

Compilation failed:

WARNING: Shader Unsupported: 'Hidden/FastBlur' - Setting to default shader.​

This was working fine before 5.5 - does anyone else experience this? The error messages are from Xcode and build time.

Any assistance greatly appreciated.

Many Thanks

 

Mine too. I don't know why, but only iOS fails to compile it, so I can't use blur effect now.. Is this bug of Unity or Xcode??

 

Ok, I tested it with Unity 5.5.0f3, and I got this bug. So, I upgraded Unity to 5.5.1f1 after I checked the release note which describes the fix for translating shader codes for Metal. BUT, this bug still happens.. Any help?

Thank you for noticing me!
