[Metal][iOS] Weather/Diffuse Shader error: "Compilation failed: cannot use as_type cast"
Steps to reproduce:
1. Open the attached project
2. Build to iOS
3. Observe the cube in iOS device
Expected result: cube is black&white
Actual result: cube is pink, Debug log is flooded with these messages:
Compilation failed:
program_source:97:29: error: cannot use as_type to cast from 'half' to 'int', types of different size
u_xlati9 = u_xlatb2.y ? as_type<int>(u_xlat16_2.x) : int(0);
^~~~~~~~~~~~~~~~~~~~~~~~~~
program_source:115:53: error: cannot use as_type to cast from 'half' to 'unsigned int', types of different size
u_xlati22 = int(uint(u_xlatb22) * 0xffffffffu | as_type<uint>(u_xlat16_2.y));
^~~~~~~~~~~~~~~~~~~~~~~~~~~
program_source:119:34: error: cannot use as_type to cast from 'half' to 'int', types of different size
u_xlati22 = u_xlatb4.y ? as_type<int>(u_xlat16_2.x) : int(0);
^~~~~~~~~~~~~~~~~~~~~~~~~~
Reproduced on: 5.5.4p2, 5.6.3f1, 2017.1.0p5, 2017.2.0b6 (Metal)
Could not reproduce on: 2017.3.0a4, on this version the shader has a compile error in the editor:
Too many texture interpolators would be used for ForwardBase pass (11 out of max 10)
Thus the cube is purely white on both Metal and OpenGLES2

FIXED IN 2017.3
The line "#pragma target 3.0" should be commented out or removed.
