I did two sample applications in ios.Both applications i have done using storyboard.Then after i did i copied the two classes of one application to another.Then i saved and compiled,it worked>But second time when i build the application and when i run that application,am getting error like this:
Couldn't register BundleIdentifier.application name with the bootstrap server.Error:unknown
error code.
This generally means that another instance of this process was already running or is hung in the debugger.(gdb)
How to resolve this error?Please give me some suggestions in resolving this issue.
The reason for this error is that you are testing app in either simulator or device and suddenly change for another without stopping it.
For this you need to properly close app from navigator before moving for another ios selection.
if encounter this problem then restart xcode and simultor(also reset simulator).

I am currently working on an IOS app built through Swift on Xcode. Firebase packages are installed using Cocoapods, and all pods are updated. Additionally, I double-checked that the Plist and Google-Service Info files are correct.
This is the full error line I receive when logging into the app and trying to retrieve user information from the database:
nw_proxy_resolver_create_parsed_array [C3.1.1 proxy pac] Evaluation
error: NSURLErrorDomain: -1003
I am unable to figure out how to resolve this issue as there were no changes in my code and it was working beforehand perfectly.
I can provide code snippets if needed but since the app was working prior, I am assuming this isn't related to my code.
The only time I was able to solve this issue temporarily was to reset the package caches through XCode, allowing me to view posts and other content pulled from the firebase backend. Unfortunately, after I restarted the app, this solution did not work anymore, and the same error from above popped up. Since resetting the package caches worked initially, I am assuming there is no direct correlation between the error and my source code.
Does anyone have any idea as to ways I can solve this issue? It has prevented me from working on my app for several days now. Thanks for any help!
Update: After looking over my code one more time, I found that there was a missing dot in a line of code, leading to my IOS app not running. This did NOT solve the error of nw_proxy_resolver_create_parsed_array [C3.1.1 proxy pac] Evaluation error: NSURLErrorDomain: -1003, but since the app is working successfully, my problem is solved.
I'm trying to get my swift Mac app to launch at login using the method described in this page: https://theswiftdev.com/how-to-launch-a-macos-app-at-login/
However, I keep getting the following errors as soon as I call SMLoginItemSetEnabled:
Could not locate login item com.domain.LauncherApplication in the caller's bundle
Could not enable login item: com.domain.LauncherApplication: 3: No such process
I checked that the launcher app ID is correct multiple times, I tried changing it and changing its version number. I even tried cleaning the project and moving the base app to /Applications but I always get these error messages.
Any idea what the problem might be? (Notice the solution must not require me to disable App Sandboxing)
OK, I found the problem but it took a long time since it was so sneaky: In the Copy File Build Phase section I entered "Contents/Library/LoginItem" as the subpath instead of "Contents/Library/LoginItems" (notice the 's' in the end - can't believe I missed it). So thank you #vadian! You were absolutely right.
I have a set of UI automation test cases for my iPhone app.
These tests run fine on the iOS 9 and 8 simulator however when I change to the most recent simulator (10.2) I get this error in my terminal
objc[8642]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x11f55b998) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x11f37d880). One of the two will be used. Which one is undefined.

2017-01-06 10:50:52.142 MyAPP[8642:947316] [Crashlytics] Version 3.7.3 (114)
Any idea why this is happening? Has anyone else experienced this?
The messages you're showing seem to indicate two distinct problems. The first is that you have two definitions of PLBuildVersion. The second is the "This app is not allowed to query..." issue.
The likely cause of the second problem is that you need to declare the schemes your app uses in your Info.plist. Use the key LSApplicationQueriesSchemes and list the schemes you want to look for. Without that, your call to -canOpenURL: will fail as you've seen.
The first problem is nicely described in Class PLBuildVersion is implemented in both frameworks, and from what I read there it doesn't seem to be anything to worry about.
So, I have an iOS tabbed app (live and free in the store [http://itunes.com/apps/iphoundyou]). One tab is a grouped tableview, with the number of groups (1 or 2) dependent on some JSON that a web service returns. The JSON is valid and straightforward. Handling it seems to be easy, and, when run in the simulator, behaves as expected. However, I just found that when run on the device, if the two section reaction is needed...it crashes.
"ok" I thought "I'll just hook up my device, launch the debugger, replicate the crash, and figure out where I have a bug"
However, when I did that, I get the most unhelpful response I could expect:
So, given that it works in the simulator, is there any suggestions as to how else to track down the flaw? The code for the tableview is nothing special, along the lines of "if this JSON key exists, number of sections=2...with the number of rows of that section equal to the number of items in another array within the JSON"
Another note: I recently started seeing a dozen or so of these when launching an app:
unable to read unknown load command 0x25
unable to read unknown load command 0x26
Thanks so much.
In my case it turned out that it was just my own error: I'd updated my device OS but didn't have that SDK (I was behind in updating XCode)
I'm able to complete my iphone app using core data internally.
But for the first time when I'm running in simulator or on device its crashing with following error:
2010-03-18 10:55:41.785 CrData[1605:4603] Unresolved error Error Domain=NSCocoaErrorDomain Code=513 UserInfo=0x50448d0 "Operation could not be completed. (Cocoa error 513.)", {
NSUnderlyingException = Error validating url for store;
}
When I run the app again in simulator or on device, its running perfectly. I'm not able to identify the exact problem. Can some one guide me on how to proceed further???
You need to unroll the errors and see what is going on. Inside of that error (which you can set a break point on objc_exception_thrown to catch it) is the userInfo dictionary which you can interrogate to see what the underlying errors are.
update
What does your NSPersistentStoreCoordinator creation code look like?
Did you add a break point and do a po [error userInfo] so see if there were any additional errors in the userInfo?
Core Data can and does send you a hierarchy of errors and frequently on a small amount of information is exposed at the top error. Unrolling the errors via the debugger is best to determine the underlying causes.
update
Code error 513 means, write permissions for creating store in core data app failed. But the same piece of code is running well from next time. So, what might be the actual problem is not known to me..... how to proceed here.
Again, what does your persistent store creation code look like? You need to post some code so that I can take a look at it. Otherwise I am just guessing which is no fun.
8.2 has become more strict on the location (and permissions) of your persistent store. I've just seen the "513" error appear when the database was stored in the bundle and used with a read only option. Using a device with 8.1 it worked without failing, but on 8.2 the error and exception appeared causing a crash. On the simulator the exception did not occur and happily continued to work.
The solution that worked to copy the database into the application documents directory at start up.
NSFileManager copyItemAtURL:toURL:error will come in useful.
