In Swift and Objective-C, the easiest way (and thread safe too) is to do:

//assume that the image is loaded in landscape mode from disk
UIImage * LandscapeImage = [UIImage imageNamed: imgname];
UIImage * PortraitImage = [[UIImage alloc] initWithCGImage: LandscapeImage.CGImage scale: 1.0 orientation: UIImageOrientationRight];

This only modifies the orientation data of the image - the pixel data is untouched. For some applications, this may not be enough.

Or in swift:

let PortraitImage  : UIImage = UIImage(CGImage: LandscapeImage.CGImage , scale: 1.0 , orientation: UIImageOrientation.Right)
