This still doesn't work with 6.4.x.
This will be fixed in a future x.ios release. However, our support for constrained calls (i.e. calls
made through variables whose type might be a reference type or valuetype at runtime) is still limited.
Thanks for the update. Is there any workaround you could suggest?
Fixed the rest of the cases as well.
Wow. That was quick! Great job. Any idea when this will hit iOS Beta?
The fixes will be in the not-yet released 6.4.4.
Verified the test case passes. App loads and I can generate GUIDs.
