I don&#39;t know why, but on my end deleting the app from simulator solved this.

Run Activity Monitor and force Kill the simulator process. Then Run you app again and simulator will launch automatically and problem goes away. 

I think this may be because you have installed (run) it on 64bit iOS7 simulator and now you are trying to use same install/files on 32bit simulation.

1) Press stop button from Xcode

2) Exit Simulator

3) Press run button again from Xcode

This is the quickest workaround that I have tried, did not have to delete the app or do anything like that.

Restart simulator, if it wont solve your problem and then delete all content. It worked for me.

I noticed I started getting this error when manually editing files that are in the Emulator&#39;s disk space.

With &quot;the Emulator&#39;s disk space&quot; I mean a path similar to this one:
~/Library/Application Support/iPhone Simulator/7.0/Applications/&lt;some large UID&gt;/&lt;My apps name&gt;.app/

Having the build process re-run solved my problems too so I feel like it has something to do with file permissions or some sort of checksum failure.

Is there a way to change the node_modules folder location?

For example: 

    - dir1
    - dir2
    - node_modules

to:

    - dir1
    - dir2
        - node_modules

I need help for how to detect if an input contains a Japanese emoji/emoticon.

Currently my character set is `charset=utf-8`. On inputting text, the user can enter Japanese characters/alpanumerics/symbols but if they insert an emoji, `onsubmit` JavaScript will check if there is an emoji, error message will display.

I can&#39;t get this to work because I have no idea on how to detect an emoji in JavaScript?

Launching apps from Xcode 5 to the iOS simulator (multiple OS versions) fails with `SpringBoard failed to launch application with error: -3`. I can get around the problem by &#39;turning it off and back on again&#39; (quitting the simulator and relaunching, uninstalling and redeploying the app, etc.), but it seems to come back again later and in other projects.

Can someone help me understand what the real problem here is and if there is a permanent fix?

I&#39;ve been reading up on how to transfer data between iOS devices over Bluetooth using GameKit.  I&#39;m not writing a game, per se, but do have a need to transfer a small amount of binary data between two devices.  Between two iOS devices, this is easy enough.  However, I was wondering if it is possible to transfer data between an iOS device and an Android device via the same mechanism.  

Has anyone come across documentation/tutorial that would explain how to do this?  Is it even technically possible?  Or has Apple put in some sort of restriction that would prevent this?

The other option I discovered was Bonjour over Bluetooth.  Would this be a more suitable option for this type of operation?

For some web pages we use the swipe left and right functionality of iPhone to pull up the menus. 
Now with iOS7, they have introduced the ability to go back and forward to previous and next pages of browser history on swipe left and right motions.

But is there a way to disable it for specific pages so as to not have conflicting behavior on the swipe actions?

iOS 7 - is there a way to disable the swipe back and forward functionality in Safari?

I am getting this error only in iOS 7 and the application crashed. 
In iOS 6, I never get any error, just once of memory warning when opening the camera.

    Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.

Here is what I am doing.

    imagePicker = [[UIImagePickerController alloc] init];
    [imagePicker setDelegate:self];
    [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
    [imagePicker setAllowsEditing:YES];
            
    [self presentModalViewController:imagePicker animated:YES];

I did tried to delay the `presentModalViewController`, but I am still getting the same message. After few seconds (7-10), the application crashed.

This error is only present in iOS 7. 

Anybody has the clue?

With the 64 bit version of iOS we can&#39;t use `%d` and `%u` anymore to format `NSInteger` and `NSUInteger`. Because for 64 bit those are typedef&#39;d to `long` and `unsigned long` instead of `int` and `unsigned int`.

So Xcode will throw warnings if you try to format NSInteger with %d. Xcode is nice to us and offers an replacement for those two cases, which consists of a l-prefixed format specifier and a typecast to long. Then our code basically looks like this:

    NSLog(@&quot;%ld&quot;, (long)i);
    NSLog(@&quot;%lu&quot;, (unsigned long)u);

Which, if you ask me, is a pain in the eye. 


A couple of days ago someone at Twitter mentioned the format specifiers `%zd` to format signed variables and `%tu` to format unsigned variables on 32 and 64 bit plattforms. 

    NSLog(@&quot;%zd&quot;, i);
    NSLog(@&quot;%tu&quot;, u);

Which seems to work. And which I like more than typecasting. 

But I honestly have no idea why those work. Right now both are basically magic values for me.  
 
I did a bit of research and figured out that the `z` prefix means that the following format specifier has the same size as `size_t`. But I have absolutely no idea what the prefix `t` means. So I have two questions:

What exactly do `%zd` and `%tu` mean?

And is it safe to use `%zd` and `%tu` instead of Apples suggestion to typecast to long?

---


*I am aware of similar questions and Apples 64-Bit Transition guides, which all recommend the `%lu (unsigned long)` approach. I am asking for an alternative to type casting.* 

Alternatives to type casting when formatting NS(U)Integer on 32 and 64 bit architectures?

How can I get the right coloring for my translucent navigation bars in iOS 7? The navigation bar just adjusts the given color to a much brighter one. Changing brightness or saturation of the color also doesn&#180;t deliver the right result.

Anyone having the same trouble? It seems to work somehow, looking at Facebook: they&#180;re having their colors and translucent navigation bars.

Edit: Just to make it clear: I need the Bar to be translucent, not transparent (with some alpha), not solid! http://en.wikipedia.org/wiki/Transparency_and_translucency

I have all my code signing entitlements set correctly. Running the app on my phone is fine, but launching it in instruments gives me an error message:

    Error Starting Recording
    At least one target failed to launch; aborting run

And then:

    Target failed to run. Permisson to debug [app name] was denied. The app must be signed with a development identity (i.e. iOS Developer)

Any ideas how I could stop this from happening? Doesn&#39;t happen on my iPad.

Can&#39;t launch my app in Instruments: At least one target failed to launch

This is for an existing app that compiled and distributed multiple times. Since updating to Xcode 5 I have this error popping. 

  1. I have my developers profile selected in the Code Signing for debug. 
  2. Deleted the Derived Data a few times.
  3. Quit a few times
  4. Downloaded and tried to re-add my Developers certificates.
  5. Reset my computer! And checked updates
  6. Tried using black magic!
  7. The Scheme &gt; Build Configuration is set to Debug

The odd circumstances I am compiling to compile to iOS 6.1 so I can run on my iPhone 3GS - the base is SDK iOS 7? Could this be an issue? I just need to test it before finding a newer phone to before change it to iOS 7.

Xcode : failed to get the task for process

I&#39;m starting new project in Xcode 5. I want to develop application using `iOS SDK 7` but with deployment target `iOS 5.0`. As soon as I create new project in Xcode and try to change deployment target to 5.0, I&#39;ve got this message:

    Applications including an arm64 slice are not compatible with versions of iOS
    prior to 6.0
    Adjust your Architectures build setting to not include arm64 in order to deploy
    to releases prior to iOS 6.0.

So changed architectures to `Standard` (no 64bit). I compiles, runs but I do not really understand what just happend.&lt;br&gt;&lt;br&gt;What&#39;s the difference between `Architectures` and `Valid architectures` settings in Xcode project Build Settings?&lt;br&gt;If I set `Architectures` to exclude 64-bit what happens when I run my app on 64-bit iPhone or iOS Simulator (I know it works, I&#39;m just curious what hapens underneath)?&lt;br&gt;Can you explain big mess with new 64-bit architecture?

I&#39;ve struggling with this for hours. I have 2 same provisioning profiles I&#39;ve created and the new profile didn&#39;t substitute the old one (which expires 6 days earlier than the new one). Through the XCode 5 menu I can&#39;t seem to delete the duplicate provisioning profile. Any workaround in this situation?

I&#39;m the only one to have a slow simulator since the last OSX update (Mavericks)?

 - I&#39;ve tried to reset simulator
 - I&#39;ve tried to switch on/off animation speed in Debug main bar
 - I&#39;ve tried to draw my game with a simple moving quad
 - I&#39;ve tried to run my application on IOS7, IOS6 with Retina and without on the simulator
 - My application isn&#39;t slow when I run it on an Android device

Simulator is always slow, on the previous OSX version I haven&#39;t got any problems :/
(My application is a game using OpenGL ES2)

Thanks!



IOS simulator slow with Mavericks

I&#39;m working with xcode 5, and often get `The Simulator can&#39;t be launched because it is already in use.` when it&#39;s not running or open (i.e. after i do: quit simulator). 

I stopped the application &amp; don&#39;t have any other project that is open, running or using the simulator (please avoid these kind of suggestions). 

this happens after i get and exception.

how can I &quot;free&quot; the simulator process without having to reboot my computer (right now that is the only solution i found) I&#39;ve tried:

 1. simulator --&gt;services--&gt;a reset content and settings
 2. closing xcode and re-opening
 3. xcode --&gt; developer toos --&gt; simulator --&gt;(open the simulator) quit simulator
 4. Activity monitor --&gt; (the simulator is closed so nothing here to force close)

also the exception is not getting caught in any of my try catch so i wondering if which tool from the developer instrument can help me figure out what is wrong.

The iOS Simulator is too large on the screen. I saw all the settings but nothing. Please help me!

In **Xcode5** there is simple option to Delete derived data:

In organiser menu (&lt;kbd&gt;cmd&lt;/kbd&gt; + &lt;kbd&gt;shift&lt;/kbd&gt; + &lt;kbd&gt;2&lt;/kbd&gt;):

![enter image description here][1]


But with new interface of Xcode6 there is no similar options.

Is there any quick methods to delete this trough **Xcode6** interface?

Or now I should remove this folders in system manually?

How to &quot;Delete derived data&quot; in Xcode?

I&#39;ve also installed on a 10.10 partition and have access to the iOS 8.0 simulators there, but for some reason when following the same setup process on 10.9 no 8.0 simulators are available, I only have the option to use &#39;iOS Device&#39;.

My command line tools are the latest ones for Mavericks and selected under &#39;locations&#39;. If I change my deployment target I can launch a 7.1 simulator. The only potential outlier is that I use iRamDisk to manage simulator and derived data file storage. However, I&#39;ve disabled this, uninstalled and reinstalled Xcode to no avail. Could other Xcode installations be conflicting?

Any help or ideas are much appreciated. Thanks.

Using Xcode 6 on 10.9 no iOS 8.0 simulator available

I am building an iOS app in Xcode 5, and I&#39;m having trouble adding layout constraints. In Xcode 4.x, I could just add leading/trailing/top/bottom spaces to container (superview) to any UI element. Now, I only have this option:

![enter image description here][1]

I want to add a &quot;bottom space to superview&quot; constraint to my text view. It says &quot;spacing to nearest neighbor&quot;, but I don&#39;t want to create a constraint to &quot;nearest neighbor&quot;, I have something else under my text view, and I don&#39;t want to create a constraint with that. If there is no other object under my text view, it adds a constraint to the container correctly. But if I try to change anything, everything messes up: I need to move all the views somewhere else, then add the constraint, then add move the other views back. If I add a constraint between the text view and the UI element (a button, in this case), it doesn&#39;t work (everything seems correctly: button has a constraint to superview&#39;s bottom, and text view has a vertical spacing constraint with the button, and there are no conflicting constraints). The UI elements appear out of screen bounds in different (3.5 inch) screen orientations. Is there a bug with the Interface Builder, or am I missing something? When I could set everything up correctly, my controls still seem out of bounds when I resize the interface builder screens, but display correctly on simulator/device at 3.5 inches. What is the &quot;best practice&quot; of designing the UI with the new Interface Builder constraints in Xcode 5?

**UPDATE:** I&#39;m having some more trouble in another project with the same thing. I am trying to fix a view&#39;s top to the top layout guide exactly by CTRL-dragging my control to where it says &quot;top layout guide&quot;, and it is trying to aling the bottom of my control to the layout guide (by about -470 points) instead of alinging the top of my control, which doesn&#39;t make any sense as the control should layout itself in variable height screens (e.g. regular and 4-inch iPhone, and the possible other layouts in the future..). Here is a screenshot of what&#39;s happening:

![enter image description here][2]

And I&#39;m getting this in constraints:

![enter image description here][3]

How can I make Interface Builder align the *top* of the view to the top layout guide?

**UPDATE 2:** I&#39;ve found a workaround. I first resize the view to decrease it&#39;s height (so the top of it will not overlap or be very close to the top layout guide) and THEN I CTRL+drag it to the top layout guide. It seems to work correctly. After I connect it, I resize my view again to the desired size and select `Update Constraints`. It works, but it&#39;s still not a solution as it requires resizing the view, connecting, resizing again, and updating constraints.

Add spacing constraint to superview in Xcode 5

It appears that: 

`[[NSBundle mainBundle] pathForResource:@&quot;name&quot; ofType:@&quot;png&quot;];`

Does not return anything for assets that are inside the Images.xcassets asset catalog.  I also tried:

`[[NSBundle mainBundle] pathForResource:@&quot;name&quot; ofType:@&quot;png&quot; inDirectory:@&quot;Images&quot;];`

`[[NSBundle mainBundle] pathForResource:@&quot;name&quot; ofType:@&quot;png&quot; inDirectory:@&quot;Images.xcassets&quot;];`

But neither of those worked either.

Has anyone had success retrieving paths to assets in the catalog?

I have an app that incorporates many round rect buttons. However, in xcode 5, those dont exist. How do I get the round rect buttons back? They are essential to my app. Now it just is pressable text. What do I do? I am planning on releasing this app later, if that is relevant.
