I solved this problem by entering 

    Xcode &gt; Preferences &gt; Locations 

And [assigning the Command Line Tools][1]

This is in Xcode Version 7.2 beta (7C46t)

In Xcode, open the **Xcode** menu at the top, then select **Preferences…**, and then select the **Locations** tab.

In Terminal, try this. 

    sudo xcode-select -s /Applications/Xcode.app

***/Applications/Xcode.app*** is your Xcode.app path.

if U still get error in terminal.

try  `sudo xcodebuild -license` to agree  license.

Got similar issue on executing command 

```
./Scripts/bootstrap.sh -d.
```

This helped me `Xcode &gt; Preferences &gt; Locations, Set Command line Tools`

I had the same problem. My application was working well but suddenly in next run, it started throwing the &quot;simctl&quot; error. It seems I had started Xcode update installation in the background.

**Fix**: I just started the Xcode application and it prompted to install some pending tools update. After Xcode updates, my app started working normally.


While running Xcode, open the **Xcode** menu, go to **Preferences…**, then select **Locations**

In Locations, &quot;Command Line Tools&quot;, choose your version of Xcode.

It should be fine. This worked for me.

Choose Xcode **Preferences** then choose **Locations** tab and inside go to **command line tools** Drop down box and choose one.

Problem sovled !

FYI:
I tried this with Xcode 12.3

If you are interested in command line &quot;approach&quot;, please try: `installer -pkg /Applications/Xcode.app/Contents/Resources/Packages/XcodeSystemResources.pkg -target /`. In addition, please make sure that `xcode-select -s` selected right Xcode installation path.

 

adding xcode in preference-&gt; locations works fine

In React you can clearly create an object and assign it as an inline style. i.e.. mentioned below. 

&lt;!-- language: lang-js --&gt;

    var divStyle = {
      color: &#39;white&#39;,
      backgroundImage: &#39;url(&#39; + imgUrl + &#39;)&#39;,
      WebkitTransition: &#39;all&#39;, // note the capital &#39;W&#39; here
      msTransition: &#39;all&#39; // &#39;ms&#39; is the only lowercase vendor prefix
    };

    var divStyle2 = {fontSize: &#39;18px&#39;};
    
    React.render(&lt;div style={divStyle}&gt;Hello World!&lt;/div&gt;, mountNode);

I have the following structure:

`FormEditor` - holds multiple instances of FieldEditor
`FieldEditor` - edits a field of the form and saving various values about it in its state

When a button is clicked within FormEditor, I want to be able to collect information about the fields from all `FieldEditor` components, information that&#39;s in their state, and have it all within FormEditor.

I considered storing the information about the fields outside of `FieldEditor`&#39;s state and put it in `FormEditor`&#39;s state instead. However, that would require `FormEditor` to listen to each of its `FieldEditor` components as they change and store their information in its state.

Can&#39;t I just access the children&#39;s state instead? Is it ideal?

I am developing an app that allows to do survey. My layout is generated from XML based questions. 

I need to create radio buttons (single choice) and checkboxes (multiple answers). I did not find anything useful for swift. 

Does anyone have an idea?

Is it possible to use an Enum as a property for my model? I currently have a class like this:

    class Checkin: RLMObject {
      dynamic var id: Int = 0
      dynamic var kind: String = &quot;checked_in&quot;
      var kindEnum: Kind = .CheckedIn {
        willSet { self.kind = newValue.rawValue }
      }
      
      enum Kind: String {
        case CheckedIn = &quot;checked_in&quot;
        case EnRoute = &quot;en_route&quot;
        case DroppedOff = &quot;dropped_off&quot;
      }
      ....
    }

It works okay, but I&#39;d like to be able to have the `kind` property be the Enum and have Realm automatically call `.rawValue` on the property when it is saving an object to the store. Is this possible in Realm or is there a feature request already out there for it?

I&#39;ve been searching google, and have only come across libraries that either reduce the height/width or some how edit the UIImage appearance via CoreImage. But I have not seen or found one library, post that explains how to reduce image size so when it uploads, it&#39;s not the full image size.

so far I have this: 

            if image != nil {
            //let data = NSData(data: UIImagePNGRepresentation(image))
            let data = UIImagePNGRepresentation(image)
            body.appendString(&quot;--\(boundary)\r\n&quot;)
            body.appendString(&quot;Content-Disposition: form-data; name=\&quot;image\&quot;; filename=\&quot;randomName\&quot;\r\n&quot;)
            body.appendString(&quot;Content-Type: image/png\r\n\r\n&quot;)
            body.appendData(data)
            body.appendString(&quot;\r\n&quot;)
        }

and it&#39;s sending 12MB photos. How can I reduce this to 1mb? thanks!

I am trying to convert this `Obj-C` code to `Swift` code but I don&#39;t know what the equivalent of this code should be ?

    #define DEGREES_TO_RADIANS(degrees)((M_PI * degrees)/180)

I googled and found [this][1]

But I don&#39;t understand how to convert that in Swift in my case?

    Crashlytics: dSYM Error
    
    Unable to process &lt;your app&gt;.app.dSYM at path /path/to/&lt;your app&gt;.app.dSYM
    Make sure your project build settings are generating a dSYM file. DEBUG_INFORMATION_FORMAT should be set to dwarf-with-dsym for all configurations. This could also be a timing issue, make sure the Crashlytics run script build phase is the last build phase and no other scripts have moved the dSYM from the location Xcode generated it.

I tried this answer https://stackoverflow.com/questions/4466095/unable-to-copy-dsym-file-into-archive but all my `Generate Debug Symbols` are set to `YES` 

Any further suggestions?

I&#39;m currently in the process of submitting my first app to the Apple store.
I&#39;ve completed the following processes

 1. Obtained a developer account
 2. Logged into the Member Center to Create an App ID
 3. Used keychain access to request and receive a distribution certificate
 4. Obtained a provisioning profile using my id and certificate

When I build the app it runs perfectly in the app simulator and on the actual ipad, however when I switch my app to `Archive` on iOS Device i have a major code sign error which i&#39;ve attached below.

I have no idea what to do to fix this, as I&#39;ve tried to make sure all the other aspects of the process were completed correctly.

One concern i did have was when i clicked the provisioning profile file it would not open and &quot;add to library&quot; wouldn&#39;t pop up (i cannot access iphone configuration utility for some reason.) I manually added the .mobileprovision file to my xcode project but i&#39;m thinking this may also be a source of my error.

Anyone, can you please help?

I&#39;m using storyboards for the first time in my app

When I close Xcode, I have 0 warnings about misplaced views or anything pertaining to my storyboard. When I restart Xcode and open the storyboard, 3 out of my 15 scenes have misplaced view warnings.

Without touching anything (other than selecting the file), I can issue a `git status` and see that the .storyboard file has changes. If I `git diff`, I see this included in multiple areas of the file:

    &lt;variation key=&quot;widthClass=compact&quot; misplaced=&quot;YES&quot;&gt;
        &lt;rect key=&quot;frame&quot; x=&quot;8&quot; y=&quot;56&quot; width=&quot;130&quot; height=&quot;34&quot;/&gt;
    &lt;/variation&gt;

If an element already had `&lt;variation key=&quot;widthClass=Compact&quot;` node, then the `misplaced` attribute and `rect` node are added.

The only thing I have to do to get the warnings to go away is click on each one, make sure &quot;Update Frame&quot; is selected, and click &quot;Fix Misplacement&quot;. That fixes everything until I restart Xcode.

The basic structure of my scene is:
    
    UIView
        UICollectionView
            UICollectionReusableView
            UICollectionViewCell
            UICollectionViewCell
        UISegmentedControl
            

How can I prevent this from happening each time I restart?

I&#39;m using **GIT** and am trying to push my code and getting the following error when using the ***Terminal***. I don&#39;t use **XCode**, I&#39;m using ***Android Studio***.

The command I tried using was: 

&gt; git branch Networking

Error:

&gt; xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun`

I am running on **El Capitan Beta 4** update if that helps in any way.

&gt; **Update**: This also happens for **IntelliJ** users, and for **MacOS
&gt; Catalina** update

change xcrun developer path for Android Studio/IntelliJ

I&#39;m having xcode issues when I try to use brew and git:

&gt;xcrun: error: active developer path (&quot;/Applications/Xcode.app/Contents/Developer&quot;) does not exist, use `xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools (or see `man xcode-select`)

I can type xcode-select and it shows that the command exists. When I type `xcode-select -p` it shows:
 
&gt;/Applications/Xcode.app/Contents/Developer

but when I do `which xcode-select`, it gives me:

&gt;/usr/bin/xcode-select

I&#39;ve tried to use the command switch and install again via Apple Developer site but none of these options have work so far... How can I fix this?
