问题
I'm trying to use arc4random_uniform in the Xcode build mentioned, but it seems to no longer be available:
An alt-click on the available functions show that they're declared in stdlib.h, which has them listed as follows:
It seems strange that its no longer available. This particular stdlib.h is within the iOS 9.0 simulator directory at usr/include/stdlib.h not sure if that helps or not.
I have the latest command line tools installed. Not sure what's going on. Any advice / help / fixes are much appreciated. Thanks in advance.
UPDATE
Seems to be an Xcode bug, references for which are:
- 22275032
- 22275176

It seems to be still available (I have been using it in 7A176x, but on El Capitan), it is just not shown in the suggestions.
