Did you manage to get your game to fill the iOS screen fully without the black bars? If so what aspect ratio settings did you have?
Also, are you implementing and native iOS features such as social sharing etc?
Iâ€™m coming to the end of the dev of my first iOS/Android game so would be grateful for any pointers or tutorials on how to get the .ipa file from my desktop to the App Store.
Yeah I did. You need to set viewport fit to cover in the project properties to support the iPhone X and use a LaunchImage in xCode with the correct iPhone X resolution as well.
I am using a 9:16 aspect ratio (portrait only),720x1280 resolution in Construct 3 & scale outer mode. Just make sure your background is bigger than the layout size so that it's not cut off of some devices with other resolutions (iPad).
Like here on the screenshot:
I haven't added any social sharing yet but using gamecenter for achievments & leaderboards!
Feel free to contact me if you have any questions!
