In tutorial, when someone debug app they see something like this: But when i start recording, by pressing red button: I see this... Make sure the Generate Debug Symbols build setting is set to Yes. You need debug symbols to have function names appear in Instruments. If your project is generating debug symbols, Instruments may not be able to find your project's dSYM file. In Instruments choose Instrument > Call Tree Data Mining > Locate dSYM file to find and open your project's dSYM file. Your project's dSYM file is usually located in the same directory as the application bundle of your project

I would like to use UIAutomation via Instruments in Xcode to test an app on my iOS device. Is it possible to do so without having to build the source code? The reason for this is that our team will have testers who will be writing automation scripts to test the apps on our devices, but we don't want them to all go through syncing to latest builds and compiling it through Xcode. Does anyone know if this is possible through UIAutomation or possibly through a 3rd party application? Thanks. You could make UIAutomation tests without the source code, but you will not see your symbols and you cant

I need to lauch iOS Simulator that uses specific language using command line. So I found that I can use instruments -w <device> and it is working great, I can set specific device. But how can I run simulator with specific language? I've tried adding -AppleLanguages -AppleLocale but there are some warnings: Instruments Usage Error : Specified target process is invalid: -AppleLanguage thanks! To run your app must be installed and located (if not, will open default language) Use this command to run your app with some language xcrun simctl launch <deviceid> <appid> -AppleLanguages "(pt-BR)" Sample

When I'm running instruments and check for leaks, it's showing leaks mainly consisting of: _ContiguousArrayStorage<String> _NativeDictionaryStorageOwner<Int, CGFloat> _NativeDictionaryStorageOwner<String, AnyObject> This is when I'm using Swift 3 and testing on devices using iOS 10. The leaks only show up in iOS 10 while on iOS 9.x everything seems to be normal. On top of that, in iOS 10 UISwitch doesn't seem to deallocate either. Currently I've been creating all kinds of workarounds trying to avoid using dictionaries and in some cases arrays, making it really annoying to code. Question:

I'm experiencing a memory leak in my application and it seems to originate from CALayer. It looks as though it only affects old iPads; I see the problem with iPad 1 & 2, but iPad Air is ok. I have a crash report from an iPad 1 showing that my app was 'jettisoned' due to insufficient memory, this leak is my main suspect. Background During operation setNeedsDisplay is continuously called every 40ms by the network thread on various UIViews to update their visuals, see function below. - (void)setNeedsRepaint { [self performSelectorOnMainThread:@selector(setNeedsDisplay) withObject:nil

I have a utility function that I suspect is eating up a large portion of my application's execution time. Using Time Profiler to look at the call stack, this function takes up a large portion of the execution time of any function from which it is called. However, since this utility function is called from many different sources, I am having trouble determining if, overall, this is the best use of my optimization time. How can I look at total time spent in this function during program execution, regardless of who called it? For clarity, I want to combine the selected entries with all other
