//Croping start from x=0; y=0; and till width=125 and height=128;

UIImage *image =imageView.image;
CGRect cropRect = CGRectMake(0, 0, 125,128);
CGImageRef imageRef = CGImageCreateWithImageInRect([image CGImage], cropRect);
[imageView setImage:[UIImage imageWithCGImage:imageRef]]; 
CGImageRelease(imageRef); 


Mask Image




- (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage {
 
 CGImageRef maskRef = maskImage.CGImage; 
 
 CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef),
  CGImageGetHeight(maskRef),
  CGImageGetBitsPerComponent(maskRef),
  CGImageGetBitsPerPixel(maskRef),
  CGImageGetBytesPerRow(maskRef),
  CGImageGetDataProvider(maskRef), NULL, false);
 
 CGImageRef masked = CGImageCreateWithMask([image CGImage], mask);
 return [UIImage imageWithCGImage:masked];

Building and Running Python Scripts with Xcode

(Open terminal type cd and drag drop that location file) in my case path is " cd /Library/Frameworks/Python.framework/Versions/3.9/bin/"  Type "ln python3.9 python39" This is for terminal part. Now create new xcode project  File > New > Project > Cross-platform > External Build System > Next Enter Name and  Enter a name (e.g. PythonLearning), and enter the path from  above Step(i.e  /usr/local/bin/python3 ) into the “Build Tool” line. Click Next.  Create a Python file Choose File > New, select macOS > Other &g
