Turning off the &#39;Automatically Sync Pasteboard&#39; option in the Edit menu of the Simulator works for me. 
I read it in Apple forums

 

This really helps! Just uncheck the Automatically Sync Pasteboard

Also read in the Apple forums that closing the simulator while working fixes this issue. So if it happens to me I close the simulator and copy-paste works fine from that point forwards.

Haven&#39;t tried it yet but I have feeling that Eva&#39;s answer is correct in that the simulator is trying to sync your pasteboard.

** Edit **

Can confirm that Eva&#39;s answer works and I no longer have this issue when I turn of automatic syncing on the simulator

The accepted answer doesn&#39;t work for me. See my comment there.
The problem is with the Handoff.

I had the **Handoff** option enabled in OS X Settings &gt; General.

After ***unchecking*** that option, I have the clipboard synced and no simulator freezes.

I have this line in my requirements file

Does that mean I need to have Django version `&gt;= 1.10` and then less than `1.11`?

I&#39;ve just updated to Xcode 9.4.1 and experienced an issue with the clipboard being cleared randomly.

So I select a text, hit `CMD+C`, then go to the position I want to paste it, hit `CMD+V`, but either

- it plays the system alert sound and doesn&#39;t paste anything, or
- it pastes a previous snippet that I copied earlier.

**Update**

Still remains with Xcode 10.1

**Update 2**

Xcode Clipboard: Copy &amp; Paste stuck

I've just updated to Xcode 9.4.1 and experienced an issue with the clipboard being cleared randomly.
So I select a text, hit <code>CMD+C</code>, then go to the position I want to paste it, hit <code>CMD+V</code>, but either
<ul>
<li>it plays the system alert sound and doesn't paste anything, or</li>
<li>it pastes a previous snippet that I copied earlier.</li>
</ul>
Update
Still remains with Xcode 10.1
Update 2
Still remains with Xcode 11

Consider the following example:

    import Foundation
    import os.log

    class OSLogWrapper {

        func logDefault(_ message: StaticString, _ args: CVarArg...) {
            os_log(message, type: .default, args)
        }

        func testWrapper() {
            logDefault(&quot;WTF: %f&quot;, 1.2345)
        }
    }

If I create a new instance of `OSLogWrapper` and call `testWrapper()`

    let logger = OSLogWrapper()
    logger.testWrapper()

I get the following output in the Xcode console:

    2018-06-19 18:21:08.327979-0400 WrapperWTF[50240:548958] WTF: 0.000000

I&#39;ve checked everything I can think of and I can&#39;t make heads or tails of what&#39;s going wrong here. Looking through the documentation isn&#39;t yielding anything helpful.

Why does wrapping os_log() cause doubles to not be logged correctly?

To play sound even on Silent mode I use to use below method. But how it&#39;s not working.

    // Works on Swift 3  
    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
    } catch {
        print(error)
    }

How to get it work in 4.2 / iOS 12?

In newer version we need to set mode and options.

    try AVAudioSession.sharedInstance().setCategory(
        &lt;#T##category:AVAudioSession.Category##AVAudioSession.Category#&gt;,
        mode: &lt;#T##AVAudioSession.Mode#&gt;, 
        options: &lt;#T##AVAudioSession.CategoryOptions#&gt;)`

I am working on an iOS app. It is working fine in Xcode 9.4.1, but when I build it in Xcode 10 it gives me following error:

I have a made a protocol in my VC in which i&#39;m getting the location placemark from one my my swift file class. In my swift class i have declare the protocol like this,

     weak var delegate: HandleMapSearch?
But the xcode is showing me error `&#39;weak&#39; must not be applied to non-class-bound &#39;HandleMapSearch&#39;; consider adding a protocol conformance that has a class bound` . It was working fine before but now when i run the app it shows this error. What is this for and how can i remove this error? This is how i have created protocol in my VC class. 

    protocol HandleMapSearch {
    func dropPinZoomIn(placemark:MKPlacemark)
    }

When updating to Xcode 10, iOS static library target fails to build. Way how I am trying to build it is following:

    xcodebuild -target TargetName -configuration Release clean build

With Xcode 9 everything runs smoothly, but when Xcode 10 is used for build, I am getting following error (after clean runs smoothly):

&gt; note: Using new build system

This probably unrelated, but I noticed that new Xcode 10 build system flags duplicated `Copy Bundle Resource` Info.plist files as errors, so I did make sure that there&#39;re no duplicated entries, but probably this error is not related to this fact.

Does anyone have any idea what might be wrong?

In Xcode 10, where is the Object Library which shows view and controller objects, code snippets and media that used to appear towards the lower right corner in Xcode 9 and older?

I&#39;d like to use the new build system of Xcode 10 for development, but our build in our continuous integration system fails since the `xcarchive` produced has an issue: the `Info.plist` in the `xcarchive` is missing the `ApplicationProperties` key and the information therein!

It turns out switching back to the legacy build system fixes this. This can be done in the workspace settings (File &gt; Workspace Settings… &gt; Build System). But I would prefer to keep the new build system for development and only use the legacy build system for CI builds.

Is there a way to make `xcodebuild` use the legacy build system without modifying the workspace?

How can I use the legacy build system with Xcode 10&#39;s `xcodebuild`?

Yesterday, I&#39;ve downloaded beta version of Xcode 11. After that, I&#39;ve opened my project and tried to run with new Xcode. Unfortunately error has occurred with message:
```Details

Failed to install the requested application
Domain: NSPOSIXErrorDomain
Code: 22
Failure Reason: The application&#39;s CFBundleVersion is invalid.
Recovery Suggestion: Ensure your bundle contains a CFBundleVersion with a valid semantic version number.
--
```

I&#39;ve closed beta version and tried to run again with latest stable version of Xcode (10.2.1), but the same error has occurred. I need to mention that before attempting to run a project with Xocde 11, it worked without any problems on Xcode 10. Nothing has been changed before and after running with beta Xcode.

What I&#39;ve already tried:

 - I&#39;ve removed Xcode 11 beta
 - I&#39;ve cleaned my project and pulled it from latest branch
 - I&#39;ve completely removed Xcode 10 from: 
 ```/Applications/Xcode.app
~/Library/Caches/com.apple.dt.Xcode
~/Library/Developer
~/Library/MobileDevice
~/Library/Preferences/com.apple.dt.Xcode.plist
/Library/Preferences/com.apple.dt.Xcode.plist
/System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.bom
/System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.plist
/System/Library/Receipts/com.apple.pkg.XcodeSystemResources.bom
/System/Library/Receipts/com.apple.pkg.XcodeSystemResources.plist
```
- And then installed fresh stable version 10.2.1

I can run other projects which was not tested with Xcode 11 without any problems.

My last idea is to just reinstall macOS, but I would like to don&#39;t do it.

Edit: I’ve forgot to mention that application is working on physical iPhone XS.

Cannot run application on simulator after installing Xcode 11 - CFBundleVersion error

With Xcode 10.2, I could select the &quot;Authors&quot; view, then select a **previous** git revision to blame from the bottom picker:
[![picker is available][1]][1]

But with Xcode 11 beta, when I select the [&quot;Authors&quot; view](https://i.stack.imgur.com/Hjc1R.png), I&#39;m unable to select a **past** revision to blame because the picker is missing:
[![picker is missing][2]][2]

Was that feature removed, or are there new steps to do to _blame_ the lines of code for a **past** revision? To illustrate it even more, I&#39;d like to see in Xcode 11 a **past** Blame like GitHub does when you [blame a specific **previous** revision]( https://github.com/EFPrefix/EFCountingLabel/blame/b84a92689bd453214c6063c6b6e77f8282e2232a/EFCountingLabel/Classes/EFCountingLabel.swift).

How to Git Blame/Authors a previous revision with Xcode 11?

When using Auto Layout, I am unable to set up a simple UIScrollView in my view controller in Xcode 11 beta. I know that I must constrain the scroll view to the edges, and then set the scroll view width and height equal to the width and height of the entire view that contains the scroll view. However, I am not getting the option to set equal widths and heights when I attempt to do so.

When I do the right-click-drag from the scroll view to the entire main view, I get the following options:

- Leading Space to Safe Area
- Top Space to Safe Area
- Trailing Space to Safe Area
- Bottom Space to Safe Area
- Center Horizontally in Safe Area
- Center Vertically in Safe Area

In other videos, there is an &quot;Equal Widths&quot; and &quot;Equal Heights&quot; option that I don&#39;t seem to have.

Am I doing something wrong, or did Apple change the way scroll views work in Xcode 11?
