Next decide the screen orientation and hit the ‘Start Build’ button.
Flowlab will then create a .ipa file you can submit to the App Store.

7. Screenshots & App Preview
Now’s the time to create the screenshots from your game that will be uploaded to iTunes Connect.
Apple announced the Simplified Screenshot Submission Process at their Worldwide Developers Conference of 2016.
With simplified screenshots, iTunes Connect allows app developers to generate screenshots for every iPhone version by simply uploading a 5.5″ screenshot asset. iTunes Connect then downsizes this 5.5″ (iPhone 7 Plus) screenshot to 4.7″, 4″ and 3.5″ to fit every device in the Apple’s iPhone family. You can also upload designs at a single size for the iPad Pro which will also downsize for the rest the iPad family.
5.5-inch Display
2208px w x 1242px h
iPad Pro (2nd Generation) 12.9-inch Display
2732px x 2048px h
You can upload up to 10 screenshots at each size.
You can also upload App Previews which are very popular and increase engagement with your game. It has been estimated that you can increase downloads by up to 20–35% by including an App Preview, and gamers who watch the video are 3x more likely to install.
You can also create screenshot sizes and upload for all individual sizes. There are also optional sizes you can resize to but it’s not necessary to do so in order to submit your game for review. Please see below specific screenshot and app preview sizes.
