Filter the images using the image.imageOrientation property.
UIImageOrientation ref - Here
You can use PHAsset class to fetch all the images with required specification by using predicate.And then filter the images based on the image.imageOrientation
Eg:-
let options = PHFetchOptions()
options.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: true)]
var images = PHAsset.fetchAssets(with: .image, options: options)

PHAsset does not provide any predicate or subtype to show image picker only landscape photos ?, I need to create custom picker – Maha Khan Jan 17 '17 at 08:08

Yes...there is no predicate to identify the image orientation. – user3608500 Jan 17 '17 at 08:16

Using custom picker will you able to access multiple images at same time? – user3608500 Jan 17 '17 at 08:17

Or you can use "pixelWidth" and "pixelHeight" properties to identify the orientation by comparing the height and width. – user3608500 Jan 17 '17 at 09:22
