UIProgressView saves reset to 0.0

Question

I have a UIProgressView in my storyboard connected to my code. I am trying to set progress to something non-zero.

Here is an example of my code that I posted in viewDidLoad.

[self.progressBar setProgress:(float)someValueBetween0.1and1.0 animated:NO]; 

However, what happens is that the progress bar will be at the value I set, and then quickly animate to 0.0. For example, if I set the stroke to 0.5, the panel will be filled halfway when the preview loads, and then drops to 0.0.

I tried using

 self.progressBar.progress = (float)someValueBetween0.1and1.0; 

That didn't work either.

I do not change the progress of the progress bar through code elsewhere. I tried Googling, read the link to the UIProgressView class, and looked for a stack overflow without any success: /

Edit: Created a new project with nothing more than a UIProgressView, to be sure that this is not something else in my code. Still not working.

 #import "ViewController.h" @interface ViewController () @property (weak, nonatomic) IBOutlet UIProgressView *testProgressView; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; [self.testProgressView setProgress:1.0 animated:NO]; }

This is a bug in Xcode version 7.0 beta (7A120f).

I have confirmed this in both Objective-C and Swift.

This only happens in beta, the same source code runs correctly in Xcode 6.

A very strange mistake.
