iPhone 7 problem

[JDiDev]

This works well on previous devices, but on iPhone 7/plus the color picker image remains unchanged. I guess it has something to do with iPhone 7 having a wider color spectrum (extended rgb) than what was before.

Seeing the same issue. I've noticed this only happens with a physical device. Color picker renders properly on iPhone 7 simulator

Having the same problem. Anyone found a solution yet?

@MrMatthias can you at least try to point me in the right direction with this issue? Or update the status? This is a blocker for any production iOS 10 application.

@aChase55 @sarperdag @JDiDev Can you set the colorspace in PickerImage::createImageFromData like this and see if it fixes the problem:
let colorSpace = CGColorSpace.init(name: CGColorSpace.sRGB)!
I don't have a device to test it

[sarperdag]

already tried it and it's not working...

[aChase55]

I tried to quickload view the img variable in ColorPicker's drawRect method and got this

[Example] ImageIO: handle_error:350: zlib error
[Example] ImageIO: handle_error:350: No IDATs 

Looking into it

[aChase55]

I think it might be a threading issue. The A10 processor in the iPhone7 devices could be causing a race condition when rendering ColorPickerImage

This would also explain why the issue is only occuring on physical iPhone 7 devices

[MrMatthias]

@aChase55 can you try to disable the changeSize method in PickerImage? Locking should be coordinated in the ColorPicker class which is not the case.

@MrMatthias

Made the following changes:

Still seeing the same:

I just ran into this issue as well. iPhone 7 does not show the Color Picker. Did anyone find a fix for this?

@MrMatthias - I see that it does not affect BinaryClock app - any more ideas?

I have ported the solution for example branch, will do for master as well.
