The simplest solution is probably just to redefine the functions Apple took away. Example:

    func CGRectMake(_ x: CGFloat, _ y: CGFloat, _ width: CGFloat, _ height: CGFloat) -&gt; CGRect {
        return CGRect(x: x, y: y, width: width, height: height)
    }

Put that in your module and all calls to `CGRectMake` will work again.


Short answer: don&#39;t do it. Don&#39;t let Apple boss you around. I _hate_ `CGRect(x:y:width:height:)`. I&#39;ve filed a bug on it. I think the initializer should be `CGRect(_:_:_:_:)`, just like `CGRectMake`. I&#39;ve defined an extension on CGRect that supplies it, and plop that extension into _every single project_ the instant I start.

    extension CGRect {
        init(_ x:CGFloat, _ y:CGFloat, _ w:CGFloat, _ h:CGFloat) {
            self.init(x:x, y:y, width:w, height:h)
        }
    }

That way, all I have to do is change &quot;CGRectMake&quot; to &quot;CGRect&quot; everywhere, and I&#39;m done.


Apple actually does provide this feature. All you have to do is go to:

And then follow the onscreen prompts.

This will solve your syntax issues and you won&#39;t have to make new functions for all of the various removed functions.

I need to get an image from the gallery on a button click and show it into the imageview.

I am doing it in the following way:

        btn_image_button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                
                getImageFromAlbum();
            }
        });

The method Definition is as:

       private void getImageFromAlbum(){
        try{
            Intent i = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(i, RESULT_LOAD_IMAGE);
        }catch(Exception exp){
            Log.i(&quot;Error&quot;,exp.toString());
        }
    }

The activity result method is

      @Override
      protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RESULT_LOAD_IMAGE &amp;&amp; resultCode == RESULT_OK &amp;&amp; null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

            try {
                bmp = getBitmapFromUri(selectedImage);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            image_view.setImageBitmap(bmp);
           
            //to know about the selected image width and height
            Toast.makeText(MainActivity.this, image_view.getDrawable().getIntrinsicWidth()+&quot; &amp; &quot;+image_view.getDrawable().getIntrinsicHeight(), Toast.LENGTH_SHORT).show();
        }

    }


----------

The Problem
-----------

The problem I am facing is when the image resolution is high suppose that if the image size is of 5mp to 13mp. It won&#39;t loads up and show up into the image view.

But the images with the low width and height are successfully loading into the image view!

Can somebody tell me any issues with the code and what I am doing wrong? I just want to import the camera images from the gallery and show them in the image view!

the Local Executor spawns new processes while scheduling tasks. Is there a limit to the number of processes it creates. I needed to change it. I need to know what is the difference between scheduler&#39;s &quot;max_threads&quot; and

Now that CGRectMake , CGPointMake, CGSizeMake, etc. has been removed in Swift 3.0, is there any way to automatically update all initializations like from `CGRectMake(0,0,w,h) to CGRect(x:0,y:0,width:w,height:h)`. Manual process is.. quite a pain.

Not sure why Apple don&#39;t auto convert this when I convert the code to Current Swift Syntax...

I recently downloaded the **Advanced NSOperations** sample app from Apple and found this code...

    // Operators to use in the switch statement.
    private func ~=(lhs: (String, Int, String?), rhs: (String, Int, String?)) -&gt; Bool {
        return lhs.0 ~= rhs.0 &amp;&amp; lhs.1 ~= rhs.1 &amp;&amp; lhs.2 == rhs.2
    }
    
    private func ~=(lhs: (String, OperationErrorCode, String), rhs: (String, Int, String?)) -&gt; Bool {
        return lhs.0 ~= rhs.0 &amp;&amp; lhs.1.rawValue ~= rhs.1 &amp;&amp; lhs.2 == rhs.2
    }

It seems to use the `~=` operator against `Strings` and `Ints` but I&#39;ve never seen it before.

What is it?

I&#39;m learning iOS development from an online course and everytime I make a custom view (custom table view cell, collection view cell, etc) the instructor always implements this initializer:

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

Why exactly do I always have to call this? What does it do? Can I put properties inside the init?


What exactly is init coder aDecoder?

I have an array of `Person`&#39;s objects: 

    class Person {
       let name:String
       let position:Int
    }

and the array is: 

    let myArray = [p1,p1,p3]

I want to map `myArray` to be a Dictionary of `[position:name]` the classic solution is:

    var myDictionary =  [Int:String]()
            
    for person in myArray {
        myDictionary[person.position] = person.name
    }

is there any elegant way by Swift to do that with the functional approach `map`, `flatMap`... or other modern Swift style

**Update**: This issue has been fixed in Xcode 8.2. Keychain works in the simulator without enabling keychain sharing.

Why am I *always* receiving error -34018 when calling `SecItemAdd` function *in Xcode 8 / iOS 10 simulator*?

## Steps to Reproduce

Create a new Single page iOS app project in Xcode 8.
Run the following code in `viewDidLoad` (or open [this][1] Xcode project).


    let itemKey = &quot;My key&quot;
    let itemValue = &quot;My secretive bee &#128029;&quot;
    
    // Remove from Keychain
    // ----------------
    
    let queryDelete: [String: AnyObject] = [
      kSecClass as String: kSecClassGenericPassword,
      kSecAttrAccount as String: itemKey as AnyObject
    ]
    
    let resultCodeDelete = SecItemDelete(queryDelete as CFDictionary)
    
    if resultCodeDelete != noErr {
      print(&quot;Error deleting from Keychain: \(resultCodeDelete)&quot;)
    }
    
    
    // Add to keychain
    // ----------------
    
    guard let valueData = itemValue.data(using: String.Encoding.utf8) else {
      print(&quot;&#128035;&#128035;&#128035;&#128035;&#128035;&#128035;&#128035;&#128035;&#128035;&#128035; Error saving text to Keychain&quot;)
      return
    }
    
    let queryAdd: [String: AnyObject] = [
      kSecClass as String: kSecClassGenericPassword,
      kSecAttrAccount as String: itemKey as AnyObject,
      kSecValueData as String: valueData as AnyObject,
      kSecAttrAccessible as String: kSecAttrAccessibleWhenUnlocked
    ]
    
    let resultCode = SecItemAdd(queryAdd as CFDictionary, nil)
    
    if resultCode != noErr {
      print(&quot;&#128029;&#128029;&#128029;&#128029;&#128029;&#128029;&#128029;&#128029;&#128029; Error saving to Keychain: \(resultCode).&quot;)
    } else {
      print(&quot;&#127808;&#127808;&#127808;&#127808;&#127808;&#127808;&#127808;&#127808;&#127808; Saved to keychain successfully.&quot;)
    }


## Expected Results


Item is added to Keychain.


## Actual Results

Function SecItemAdd returns the following error code: `-34018`.



## Version

Xcode version 8.1 (8B62), macOS Sierra 10.12.1.

## Configuration

Always occurs in Xcode 8 since Beta 2 when testing in an iOS 10 simulator.

Does NOT occur in Xcode 8 when testing in an iOS 9.3 simulator.

I have an Objective-C project in Xcode 8 Beta 3. Since updating, whenever I try to build I receive the following error:

&gt;“Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit &gt; Convert &gt; To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.

Has anyone encountered this? Since it&#39;s an Objective-C project there&#39;s no build setting to configure Swift. I have also made sure none of the project dependencies or CocoaPods are using Swift. The only solution I have is to use Beta 2. Any ideas how I might fix this issue?

I should also mention I&#39;m running OSX 10.12 Beta 2.

Hello i have working no error codes for UITextfield border color change but when using it in Swift 3 dont change textfield border color and dont gives error. I need your help my codes under below. 

    @IBOutlet weak var email: UITextField!
    @IBOutlet weak var pass: UITextField!
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let myColor : UIColor = UIColor.white()
        email.layer.borderColor = myColor.cgColor
        pass.layer.borderColor = myColor.cgColor
        
    
    }
    
     

 Thank you !

New in Xcode 8 beta 4, `NSError` is bridged to the Swift `Error` protocol type. This affects StoreKit when dealing with failed `SKPaymentTransaction`s. You ought to check to be sure the error didn&#39;t occur because the transaction was cancelled to know whether or not to show an error message to the user. You do this by examining the error&#39;s `code`. But with `Error` instead of `NSError`, there is no `code` defined. I haven&#39;t been able to figure out how to properly get the error code from `Error`.

This worked in the previous version of Swift 3:

    func failedTransaction(_ transaction: SKPaymentTransaction) {
        if let transactionError = transaction.error {
            if transactionError.code != SKErrorCode.paymentCancelled.rawValue {
                //show error to user
            }
         }
         ...
    }

Now that `error` is an `Error` not `NSError`, `code` is not a member.

Accessing code in Swift 3 Error

The Swift documentation at page 61 of the Swift manual hints to the possibility of using `where` to join an optional binding with a regular condition. Yet when I do it I have a warning suggesting me to substitute the `where` with a comma like in the following piece of code:

    if let geocodingError = error as? NSError where geocodingError.code == 2

I am trying to add a `UITapGesture` to a UIButton so it will trigger a function when tapped. I am using `Swift 3` and is getting some error:

&gt;Terminating app due to uncaught exception &#39;NSInvalidArgumentException&#39;, reason: &#39;-[SwiftRunner.ViewController tapBlurButton]: unrecognized selector sent to instance 0x149e07610&#39;

This is roughly what I have:

    // Swift 3
    import UIKit
    class ViewController {

       @IBOutlet weak var qsBlurButton: UIButton!       

       override func viewDidLoad() {
          super.viewDidLoad()
          
          let tapGesture = UITapGestureRecognizer(target: self, action: Selector((&quot;tapBlurButton&quot;)))
          qsBlurButton.addGestureRecognizer(tapGesture)
       }
    
       func tapBlurButton(sender: UITapGestureRecognizer) {
          print(&quot;Please Help!&quot;)
       }
    }

The [`ObjectiveC.swift`](https://github.com/apple/swift/blob/master/stdlib/public/SDK/ObjectiveC/ObjectiveC.swift#L228) file from the standard library contains the following few lines of code around line 228:

    extension NSObject : Equatable, Hashable {
      /// ...
      open var hashValue: Int {
        return hash
      }
    }

What does `open var` mean in this context, or what is the `open` keyword in general?
