Took screenshots for every size in the simulator and I'm having a problem with 4.7-inch (iphone 6) and 5.5-inch (iphone 6 Plus) screenshots only.... With 4-inch and 3.5-inch had no problem uploading.
Error states: One or more screenshots have the wrong aspect ratio. For more information, see the Developer Guide.
On the Dev-Guide says:
4.7-inch -> 750 x 1334 pixels for hi-res portrait
5.5-inch -> 1242 x 2208 pixels for hi-res portrait
My screenshots HAVE those dimensions, I took them with the respective simulators. Any one had a similar problem?
(Already tried renaming the screenshots, avoiding strange characters and what not... No success yet)
The iOS Simulator began scaling images. If you're scaling is anything other than 100, change it back to 100. I had the same issue, this seemed to solve it.
Just rename them to "1.png" and so on.
Run your app on the simulator, and save screen shots.
Rename those screen shots to 4.7.1 (iPhone 6), 5.5.1 (iPhone 6 plus) and so on.
set the simulator scale to 100%
Simulator > Window > Scale > 100%
It's been a temporary problem by Apple. Now it should accept your images: Uploading screenshots to iTunes connect for iPhone 6 and 6+
