Closed 5 years ago.
Can anyone who have access to iPhone 8 and iPhone X let me know the model names? It could be accessed by UIDevice.current.modelName.
The information as #Anbu mentioned are:
iPhone 8: iPhone10,1 and iPhone10,4
iPhone 8 Plus: iPhone10,2 and iPhone10,5
iPhone X: iPhone10,3 and iPhone10,6
Remember if you want to use UIDevice.current.modelName you need to create your own extension since this is not a default value in UIDevice.current.

I just wanted to ask why my app is starting with a too small size on devices other than iPhone 4s on my simulator? Is there something wrong related to the constraints I set or general project difficulties?
You must set your launch images. At least set them for iphone 6 and you should solve the issue

Enabling auto layout in iOS 6 while remaining backwards compatible with iOS 5
My boss want me do to an App compatible with iPhone 5/4/4S and iOS 6/5
Is it possible ?
Will i be able to use NSLayoutConstaint ?
You can create a single app that supports anywhere from iOS 4.3 on up and it will work on all devices that supports iOS 4.3 or later (or 5.0 and later if you choose).
However, NSLayoutContraint is only in iOS 6.0 and later. You will need to use other mechanisms for the app to support iOS 5.x.
Nope, not possible. NSLayoutConstaint are only available on iOS 6. You still can use Autoresing mask for layout purpose on iOS 5
