Hi Csounders!

Has anyone run into issues or been successful calling csoundCreateThread
from Swift 3? All the other functions I am using work but when I run this
line of code:

csoundCreateThread(performance_function, UnsafeMutableRawPointer(csound))

I get this error:

Cannot convert value of type '(UnsafeMutableRawPointer!) -> UInt' to
expected argument type '(@convention(c) (UnsafeMutableRawPointer?) ->
UInt)!'

The performance function seems to be causing an issue. It looks like the
standard c function:

uintptr_t performance_function(void* data) {
    CSOUND* csound = (CSOUND*) data;
    while (csoundPerformKsmps(csound) == 0) {}
    return 0;
}

This line of code was working in Swift 1.0 and now it seems to be broken.
Any ideas as to what needs to be changed or added? Thank you guys.

What I ended up doing was just creating a work-around, using a void function
to call csoundCreateThread from a .c instead of a .swift file:

void register_performance_function(void* data) {
    CSOUND* csound = (CSOUND*) data;
    csoundCreateThread(performance_function, csound);
}
